问题描述：查询用户信息时想级联查出用户订单以及订单详情，在查询用户的时候JDBC是will be managed by Spring，但懒加载用户订单以及订单详情时就will not be managed by Spring
Spring配置
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

service层代码，添加 事务注解
//一定要加上否则下面的方法不会被事务控制 @Transactional(value = "transactionManager") public abstract class BaseServiceImpl<T> implements BaseService<T> { public abstract BaseMapper<T> getMapper(); @Override public int deleteByPrimaryKey(Integer id) { return getMapper().deleteByPrimaryKey(id); }
@Service @Transactional(value = "transactionManager") public class UserServiceImpl extends BaseServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public BaseMapper<User> getMapper() { return userMapper; } }
