@PrimaryGeneratedColumn()
id: number;
@Column({ length: 500 })

API实现
数据库配置(main.module.ts)
TypeOrmModule.forRoot(
{
type: 'mysql',
host: mysqlConfig.host,
port: 3306,
username: mysqlConfig.userName,
password: mysqlConfig.password,
database: 'b_simple_user_center',
entities: [join(__dirname, '**/**.entity{.ts,.js}')],
synchronize: true,
},
),
全局缓存
CacheModule.register({
store: redisStore,
host: redisCacheConfig.host,
port: redisCacheConfig.port,
ttl: redisCacheConfig.ttl, // seconds
max: redisCacheConfig.max, // seconds
}),
业务层实现
该系统中使用typeorm操作数据库，常见的typeorm操作方式包Entity Manager 和Query Builder，结合系统多条件查询场景，因此采用Query Builder方式，控制层和服务层为一一对应关系，代码内参见src/controller、src/service
采坑点
nest多条件查询
...
const queryConditionList = ['c.isDelete = :isDelete'];
if (query.name) {
queryConditionList.push('c.name LIKE :name');
}
const queryCondition = queryConditionList.join(' AND ');
const res = await this.productBrandRepository
.createQueryBuilder('c')
.where(queryCondition, {
name: `%${query.name}%`,
isDelete: 0,
})
.orderBy('c.name', 'ASC')
.skip((query.page - 1) * query.pageSize)
.take(query.pageSize)
.getManyAndCount();
...
typeorm实体间任意联查
typeorm中联查任意实体（在实体关系间没有表关联）时，getManyAndCount无法查询关联字段，必须采用getRawAndEntities，typeorm文档书写有误。
...
const res = await this.productAttributeRepository
.createQueryBuilder('c')
.leftJoinAndSelect(ProductAttributeCategoryEntity, 'a', 'a.id = c.product_attribute_category_id')
.where(queryCondition, {
name: `%${query.name}%`,
isDelete: 0,
productAttributeCategoryId: Number(query.cateAttrId),
type: Number(query.type),
})
.orderBy('c.name', 'ASC')
.skip((query.page - 1) * query.pageSize)
.take(query.pageSize)
.getRawAndEntities();
...
JWT用户认证拆分单独服务
用户系统中与身份认证拆分成单独的服务（网关服务）
