Spring Boot项目中使用 TrueLicense 生成和验证License(服务器许可)

一 简介

License,即版权许可证,一般用于收费软件给付费用户提供的访问许可证明。根据应用部署位置的不同,一般可以分为以下两种情况讨论:

  • 应用部署在开发者自己的云服务器上。这种情况下用户通过账号登录的形式远程访问,因此只需要在账号登录的时候校验目标账号的有效期、访问权限等信息即可。
  • 应用部署在客户的内网环境。因为这种情况开发者无法控制客户的网络环境,也不能保证应用所在服务器可以访问外网,因此通常的做法是使用服务器许可文件,在应用启动的时候加载证书,然后在登录或者其他关键操作的地方校验证书的有效性。

注:限于文章篇幅,这里只讨论代码层面的许可限制,暂不考虑逆向破解等问题。此外,在下面我只讲解关键代码实现,完整代码可以参考:gitee.com/zifangsky/L…

二 使用 TrueLicense 生成License

(1)使用Spring Boot构建测试项目ServerDemo,用于为客户生成License许可文件:

注:这个完整的Demo项目可以参考:gitee.com/zifangsky/L…

i)在pom.xml中添加关键依赖:

<dependency>
    <groupId>de.schlichtherle.truelicense</groupId>
    <artifactId>truelicense-core</artifactId>
    <version>1.33</version>
    <scope>provided</scope>
</dependency>
复制代码

ii)校验自定义的License参数:

TrueLicense的 de.schlichtherle.license.LicenseManager 类自带的verify方法只校验了我们后面颁发的许可文件的生效和过期时间,然而在实际项目中我们可能需要额外校验应用部署的服务器的IP地址、MAC地址、CPU序列号、主板序列号等信息,因此我们需要复写框架的部分方法以实现校验自定义参数的目的。

首先需要添加一个自定义的可被允许的服务器硬件信息的实体类(如果校验其他参数,可自行补充):

package cn.zifangsky.license;

import java.io.Serializable;
import java.util.List;

/**
 * 自定义需要校验的License参数
 *
 * @author zifangsky
 * @date 2018/4/23
 * @since 1.0.0
 */
public class LicenseCheckModel implements Serializable{

    private static final long serialVersionUID = 8600137500316662317L;
    /**
     * 可被允许的IP地址
     */
    private List<String> ipAddress;

    /**
     * 可被允许的MAC地址
     */
    private List<String> macAddress;

    /**
     * 可被允许的CPU序列号
     */
    private String cpuSerial;

    /**
     * 可被允许的主板序列号
     */
    private String mainBoardSerial;

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseCheckModel{" +
                "ipAddress=" + ipAddress +
                ", macAddress=" + macAddress +
                ", cpuSerial='" + cpuSerial + '\'' +
                ", mainBoardSerial='" + mainBoardSerial + '\'' +
                '}';
    }
}
复制代码

其次,添加一个License生成类需要的参数:

package cn.zifangsky.license;

import com.fasterxml.jackson.annotation.JsonFormat;

import java.io.Serializable;
import java.util.Date;

/**
 * License生成类需要的参数
 *
 * @author zifangsky
 * @date 2018/4/19
 * @since 1.0.0
 */
public class LicenseCreatorParam implements Serializable {

    private static final long serialVersionUID = -7793154252684580872L;
    /**
     * 证书subject
     */
    private String subject;

    /**
     * 密钥别称
     */
    private String privateAlias;

    /**
     * 密钥密码(需要妥善保管,不能让使用者知道)
     */
    private String keyPass;

    /**
     * 访问秘钥库的密码
     */
    private String storePass;

    /**
     * 证书生成路径
     */
    private String licensePath;

    /**
     * 密钥库存储路径
     */
    private String privateKeysStorePath;

    /**
     * 证书生效时间
     */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date issuedTime = new Date();

    /**
     * 证书失效时间
     */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date expiryTime;

    /**
     * 用户类型
     */
    private String consumerType = "user";

    /**
     * 用户数量
     */
    private Integer consumerAmount = 1;

    /**
     * 描述信息
     */
    private String description = "";

    /**
     * 额外的服务器硬件校验信息
     */
    private LicenseCheckModel licenseCheckModel;

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseCreatorParam{" +
                "subject='" + subject + '\'' +
                ", privateAlias='" + privateAlias + '\'' +
                ", keyPass='" + keyPass + '\'' +
                ", storePass='" + storePass + '\'' +
                ", licensePath='" + licensePath + '\'' +
                ", privateKeysStorePath='" + privateKeysStorePath + '\'' +
                ", issuedTime=" + issuedTime +
                ", expiryTime=" + expiryTime +
                ", consumerType='" + consumerType + '\'' +
                ", consumerAmount=" + consumerAmount +
                ", description='" + description + '\'' +
                ", licenseCheckModel=" + licenseCheckModel +
                '}';
    }
}

最后是License生成类,用于生成License证书:

package cn.zifangsky.license;

import de.schlichtherle.license.CipherParam;
import de.schlichtherle.license.DefaultCipherParam;

    public boolean generateLicense(){
        try {
            LicenseManager licenseManager = new CustomLicenseManager(initLicenseParam());
            LicenseContent licenseContent = initLicenseContent();

            licenseManager.store(licenseContent,new File(param.getLicensePath()));

            return true;
        }catch (Exception e){
            logger.error(MessageFormat.format("证书生成失败:{0}",param),e);
            return false;
        }
    }

    /**

        //设置对证书内容加密的秘钥
        CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());

        KeyStoreParam privateStoreParam = new CustomKeyStoreParam(LicenseCreator.class

        //扩展校验服务器硬件信息
        licenseContent.setExtra(param.getLicenseCheckModel());

        return licenseContent;
    }

}
复制代码

iii)添加一个生成证书的Controller:

这个Controller对外提供了两个RESTful接口,分别是「获取服务器硬件信息」和「生成证书」,示例代码如下:

package cn.zifangsky.controller;

import cn.zifangsky.license.AbstractServerInfos;
import cn.zifangsky.license.LicenseCheckModel;
import cn.zifangsky.license.LicenseCreator;
import cn.zifangsky.license.LicenseCreatorParam;
import cn.zifangsky.license.LinuxServerInfos;
import cn.zifangsky.license.WindowsServerInfos;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

/**
 *
 * 用于生成证书文件,不能放在给客户部署的代码里
 * @author zifangsky
 * @date 2018/4/26
 * @since 1.0.0
 */
@RestController
@RequestMapping("/license")
public class LicenseCreatorController {

    /**
     * 证书生成路径
     */
    @Value("${license.licensePath}")
    private String licensePath;

    /**
     * 获取服务器硬件信息
     * @author zifangsky
     * @date 2018/4/26 13:13
     * @since 1.0.0
     * @param osName 操作系统类型,如果为空则自动判断
     * @return com.ccx.models.license.LicenseCheckModel
     */
    @RequestMapping(value = "/getServerInfos",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
    public LicenseCheckModel getServerInfos(@RequestParam(value = "osName",required = false) String osName) {
        //操作系统类型
        if(StringUtils.isBlank(osName)){
            osName = System.getProperty("os.name");
        }
        osName = osName.toLowerCase();

        AbstractServerInfos abstractServerInfos = null;

        //根据不同操作系统类型选择不同的数据获取方法
        if (osName.startsWith("windows")) {
            abstractServerInfos = new WindowsServerInfos();
        } else if (osName.startsWith("linux")) {
            abstractServerInfos = new LinuxServerInfos();
        }else{//其他服务器类型
            abstractServerInfos = new LinuxServerInfos();
        }

        return abstractServerInfos.getServerInfos();
    }

    /**
     * 生成证书
     * @author zifangsky
     * @date 2018/4/26 13:13
     * @since 1.0.0
     * @param param 生成证书需要的参数,如:{"subject":"ccx-models","privateAlias":"privateKey","keyPass":"5T7Zz5Y0dJFcqTxvzkH5LDGJJSGMzQ","storePass":"3538cef8e7","licensePath":"C:/Users/zifangsky/Desktop/license.lic","privateKeysStorePath":"C:/Users/zifangsky/Desktop/privateKeys.keystore","issuedTime":"2018-04-26 14:48:12","expiryTime":"2018-12-31 00:00:00","consumerType":"User","consumerAmount":1,"description":"这是证书描述信息","licenseCheckModel":{"ipAddress":["192.168.245.1","10.0.5.22"],"macAddress":["00-50-56-C0-00-01","50-7B-9D-F9-18-41"],"cpuSerial":"BFEBFBFF000406E3","mainBoardSerial":"L1HF65E00X9"}}
     * @return java.util.Map<java.lang.String,java.lang.Object>
     */
    @RequestMapping(value = "/generateLicense",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
    public Map<String,Object> generateLicense(@RequestBody(required = true) LicenseCreatorParam param) {
        Map<String,Object> resultMap = new HashMap<>(2);

        if(StringUtils.isBlank(param.getLicensePath())){
            param.setLicensePath(licensePath);
        }

        LicenseCreator licenseCreator = new LicenseCreator(param);
        boolean result = licenseCreator.generateLicense();

        if(result){
            resultMap.put("result","ok");
            resultMap.put("msg",param);
        }else{
            resultMap.put("result","error");
            resultMap.put("msg","证书文件生成失败!");
        }

        return resultMap;
    }

}
复制代码

(2)使用JDK自带的 keytool 工具生成公私钥证书库:

假如我们设置公钥库密码为:public_password1234,私钥库密码为:private_password1234,则生成命令如下:

#生成命令
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -keypass "private_password1234" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"

#导出命令
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"

#导入命令
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"
复制代码

上述命令执行完成之后,会在当前路径下生成三个文件,分别是:privateKeys.keystore、publicCerts.keystore、certfile.cer。其中文件certfile.cer不再需要可以删除,文件privateKeys.keystore用于当前的 ServerDemo 项目给客户生成license文件,而文件publicCerts.keystore则随应用代码部署到客户服务器,用户解密license文件并校验其许可信息

(3)为客户生成license文件:

将 ServerDemo 项目部署到客户服务器,通过以下接口获取服务器的硬件信息(等license文件生成后需要删除这个项目。当然也可以通过命令手动获取客户服务器的硬件信息,然后在开发者自己的电脑上生成license文件):

获取客户服务器的硬件信息

注:上图使用的是FirefoxRESTClient插件

然后生成license文件:

生成license文件

请求时需要在Header中添加一个Content-Type,其值为:application/json;charset=UTF-8。参数示例如下:

{
	"subject": "license_demo",
	"privateAlias": "privateKey",
	"keyPass": "private_password1234",
	"storePass": "public_password1234",
	"licensePath": "C:/Users/zifangsky/Desktop/license_demo/license.lic",
	"privateKeysStorePath": "C:/Users/zifangsky/Desktop/license_demo/privateKeys.keystore",
	"issuedTime": "2018-07-10 00:00:01",
	"expiryTime": "2019-12-31 23:59:59",
	"consumerType": "User",
	"consumerAmount": 1,
	"description": "这是证书描述信息",
	"licenseCheckModel": {
		"ipAddress": ["192.168.245.1", "10.0.5.22"],
		"macAddress": ["00-50-56-C0-00-01", "50-7B-9D-F9-18-41"],
		"cpuSerial": "BFEBFBFF000406E3",
		"mainBoardSerial": "L1HF65E00X9"
	}
}
复制代码

如果请求成功,那么最后会在 licensePath 参数设置的路径生成一个license.lic的文件,这个文件就是给客户部署代码的服务器许可文件。

三 给客户部署的应用中添加License校验

(1)使用Spring Boot构建测试项目ServerDemo,用于模拟给客户部署的应用:

注:这个完整的Demo项目可以参考:gitee.com/zifangsky/L…

(2)添加License校验类需要的参数:

package cn.zifangsky.license;

/**
 * License校验类需要的参数
 *
 * @author zifangsky
 * @date 2018/4/20
 * @since 1.0.0
 */
public class LicenseVerifyParam {

    /**
     * 证书subject
     */
    private String subject;

    /**
     * 公钥别称
     */
    private String publicAlias;

    /**
     * 访问公钥库的密码
     */
    private String storePass;

    /**
     * 证书生成路径
     */
    private String licensePath;

    /**
     * 密钥库存储路径
     */
    private String publicKeysStorePath;

    public LicenseVerifyParam() {

    }

    public LicenseVerifyParam(String subject, String publicAlias, String storePass, String licensePath, String publicKeysStorePath) {
        this.subject = subject;
        this.publicAlias = publicAlias;
        this.storePass = storePass;
        this.licensePath = licensePath;
        this.publicKeysStorePath = publicKeysStorePath;
    }

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseVerifyParam{" +
                "subject='" + subject + '\'' +
                ", publicAlias='" + publicAlias + '\'' +
                ", storePass='" + storePass + '\'' +
                ", licensePath='" + licensePath + '\'' +
                ", publicKeysStorePath='" + publicKeysStorePath + '\'' +
                '}';
    }
}
复制代码

然后再添加License校验类:

package cn.zifangsky.license;

import de.schlichtherle.license.*;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import java.io.File;

public class LicenseVerify {
    private static Logger logger = LogManager.getLogger(LicenseVerify.class);

    /**

     */
    public synchronized LicenseContent install(LicenseVerifyParam param){
        LicenseContent result = null;
        DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        //1. 安装证书
        try{
            LicenseManager licenseManager = LicenseManagerHolder.getInstance(initLicenseParam(param));
            licenseManager.uninstall();

            result = licenseManager.install(new File(param.getLicensePath()));
            logger.info(MessageFormat.format("证书安装成功,证书有效期:{0} - {1}",format.format(result.getNotBefore()),format.format(result.getNotAfter())));
        }catch (Exception e){
            logger.error("证书安装失败!",e);
        }

        return result;
    }

    /**

     * @author zifangsky
     * @date 2018/4/20 16:26
     * @since 1.0.0
     * @return boolean
     */
    public boolean verify(){
        LicenseManager licenseManager = LicenseManagerHolder.getInstance(null);
        DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        //2. 校验证书
        try {
            LicenseContent licenseContent = licenseManager.verify();
//            System.out.println(licenseContent.getSubject());

            logger.info(MessageFormat.format("证书校验通过,证书有效期:{0} - {1}",format.format(licenseContent.getNotBefore()),format.format(licenseContent.getNotAfter())));
            return true;
        }catch (Exception e){
            logger.error("证书校验失败!",e);
            return false;
        }
    }

    /**

     */
    private LicenseParam initLicenseParam(LicenseVerifyParam param){
        Preferences preferences = Preferences.userNodeForPackage(LicenseVerify.class);

        CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());

        KeyStoreParam publicStoreParam = new CustomKeyStoreParam(LicenseVerify.class
                ,param.getPublicKeysStorePath()
                ,param.getPublicAlias()
                ,param.getStorePass()
                ,null);

        return new DefaultLicenseParam(param.getSubject()
                ,preferences
                ,publicStoreParam
                ,cipherParam);
    }

}
复制代码

(3)添加Listener,用于在项目启动的时候安装License证书:

package cn.zifangsky.license;

import org.apache.commons.lang3.StringUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;

import org.springframework.stereotype.Component;

/**
 * 在项目启动时安装证书
 *
 * @author zifangsky
 * @date 2018/4/24
 * @since 1.0.0
 */
@Component
public class LicenseCheckListener implements ApplicationListener<ContextRefreshedEvent> {
    private static Logger logger = LogManager.getLogger(LicenseCheckListener.class);

    /**
     * 证书subject
     */
    @Value("${license.subject}")
    private String subject;

    /**
     * 公钥别称
     */
    @Value("${license.publicAlias}")
    private String publicAlias;

    /**
     * 访问公钥库的密码
     */
    @Value("${license.storePass}")
    private String storePass;

    /**
     * 证书生成路径
     */
    @Value("${license.licensePath}")
    private String licensePath;

    /**
     * 密钥库存储路径
     */
    @Value("${license.publicKeysStorePath}")
    private String publicKeysStorePath;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        //root application context 没有parent
        ApplicationContext context = event.getApplicationContext().getParent();
        if(context == null){
            if(StringUtils.isNotBlank(licensePath)){
                logger.info("++++++++ 开始安装证书 ++++++++");

                LicenseVerifyParam param = new LicenseVerifyParam();
                param.setSubject(subject);
                param.setPublicAlias(publicAlias);
                param.setStorePass(storePass);
                param.setLicensePath(licensePath);
                param.setPublicKeysStorePath(publicKeysStorePath);

                LicenseVerify licenseVerify = new LicenseVerify();
                //安装证书
                licenseVerify.install(param);

                logger.info("++++++++ 证书安装结束 ++++++++");
            }
        }
    }
}
复制代码

注:上面代码使用参数信息如下所示:

#License相关配置
license.subject=license_demo
license.publicAlias=publicCert
license.storePass=public_password1234
license.licensePath=C:/Users/zifangsky/Desktop/license_demo/license.lic
license.publicKeysStorePath=C:/Users/zifangsky/Desktop/license_demo/publicCerts.keystore
复制代码

(4)添加拦截器,用于在登录的时候校验License证书:

package cn.zifangsky.license;

import com.alibaba.fastjson.JSON;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;

/**
 * LicenseCheckInterceptor
 *
 * @author zifangsky
 * @date 2018/4/25
 * @since 1.0.0
 */
public class LicenseCheckInterceptor extends HandlerInterceptorAdapter{
    private static Logger logger = LogManager.getLogger(LicenseCheckInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        LicenseVerify licenseVerify = new LicenseVerify();

        //校验证书是否有效
        boolean verifyResult = licenseVerify.verify();

        if(verifyResult){
            return true;
        }else{
            response.setCharacterEncoding("utf-8");
            Map<String,String> result = new HashMap<>(1);
            result.put("result","您的证书无效,请核查服务器是否取得授权或重新申请证书!");

            response.getWriter().write(JSON.toJSONString(result));

            return false;
        }
    }

}
复制代码

(5)添加登录页面并测试:

添加一个登录页面,可以在license校验失败的时候给出错误提示:

<head>
    <meta content="text/html;charset=UTF-8"/>
    <meta http-equiv="X-UA-Compatible" content="IE=edge"/>

    <script>
        //回车登录
        function enterlogin(e) {
            var key = window.event ? e.keyCode : e.which;
            if (key === 13) {
                userLogin();
            }
        }

        //用户密码登录
        function userLogin() {
            //获取用户名、密码
            var username = $("#username").val();
            var password = $("#password").val();

            if (username == null || username === "") {
                $("#errMsg").text("请输入登陆用户名!");
                $("#errMsg").attr("style", "display:block");
                return;
            }
            if (password == null || password === "") {
                $("#errMsg").text("请输入登陆密码!");
                $("#errMsg").attr("style", "display:block");
                return;

                    "password": password
                },
                success: function (data) {
                    if (data.code == "200") {
                        $("#errMsg").attr("style", "display:none");
                        window.location.href = '/userIndex';

                        $("#errMsg").attr("style", "display:block");
                    }
                }
            });
        }
    </script>

i)启动项目,可以发现之前生成的license证书可以正常使用:

这时访问 http://127.0.0.1:7080/login ,可以正常登录:

ii)重新生成license证书,并设置很短的有效期。

iii)重新启动ClientDemo,并再次登录,可以发现爆以下提示信息:

至此,关于使用 TrueLicense 生成和验证License就结束了,文章中没有说到的类可以自行参考示例源码,谢谢阅读。
