mybatisPlus

1.所有业务层接口继承 IService<T>，T表示实体类

public interface IAgentServiceRuleService extends IService<AgentServiceRule> {}

2.所有业务层接口实现类 继承 ServiceImpl<TMapper,T>类，并实现自己的业务层接口

@Service
public class AgentServiceRuleServiceImpl extends ServiceImpl<AgentServiceRuleMapper, AgentServiceRule> implements IAgentServiceRuleService {}//AgentServiceRuleMapper是该实体类的dao接口

3.所有的dao接口继承BaseMapper<T>

public interface AgentServiceRuleMapper extends BaseMapper<AgentServiceRule> {}

4.自定义SQL语句和mybatis相同

5.
