Service业务层实现

一、 概述

1.作用

统一业务逻辑实现，方便接口调用

2.位置

cn.ewsd.xxxx.service.impl

3.命名方式

命名方式：XxxxServiceImpl.java

4.继承

cn.ewsd.frame.service.impl.BaseServiceImpl

5.公用方法

实现cn.ewsd.frame.service.XxxxBaseServiceImpl中的方法

二、示例代码

1.自定义方法示例

    @Override
    public int save(SysUser sysUser){
        return sysUserMapper.save(sysUser);
    }
                

    @Override
    public int update(SysUser sysUser){
        return sysUserMapper.update(sysUser);
    }
                

    @Override
    public int deleteBatch(String[] uuids){
        return sysUserMapper.deleteBatch(uuids);
    }
                

2.用户serviceImpl示例

    @Service("sysUserServiceImpl")
    public class SysUserServiceImpl extends SystemBaseServiceImpl implements SysUserService {
        @Autowired
        private SysUserMapper sysUserMapper;

        @Override
        public PageSet getPageSet(PageParam pageParam, String filterSort) {
            PageHelper.startPage(pageParam.getPage(), pageParam.getRows());
            List list = sysUserMapper.getPageSet(filterSort);
            PageInfo pageInfo = new PageInfo<>(list);
            return PageUtils.getPageSet(pageInfo);
        }

        @Override
        public SysUser queryObject(String uuid){
            return sysUserMapper.queryObject(uuid);
        }

        @Override
        public List queryList(Map map){
            return sysUserMapper.queryList(map);
        }

        @Override
        public int queryTotal(Map map){
            return sysUserMapper.queryTotal(map);
        }

        @Override
        public int executeSave(SysUser sysUser){
            return sysUserMapper.executeSave(sysUser);
        }

        @Override
        public int executeUpdate(SysUser sysUser){
            return sysUserMapper.executeUpdate(sysUser);
        }

        @Override
        public int executeDelete(String uuid){
            return sysUserMapper.executeDelete(uuid);
        }

        @Override
        public int executeDeleteBatch(String[] uuids){
            return sysUserMapper.executeDeleteBatch(uuids);
        }
    }
