今日想法：

写完最后一个分级查询的接口

今日作为：

package com.clxs.service.impl;

import com.clxs.dao.*;
import com.clxs.pojo.*;
import com.clxs.service.LevelService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.*;

@Service
public class LevelServiceimpl implements LevelService {

    @Autowired
    WorkDao workDao;

    @Autowired
    WorkshopDao workshopDao;

    @Autowired
    WorkerDao workerDao;

    @Autowired
    WorksDao worksDao;

    @Autowired
    MessageDao messageDao;

    public List LevelBySelect() {

        Map<String, List> map = new HashMap<>();
        List<Workshop> array2 = new ArrayList<>();
        List<Worker> array3 = new ArrayList<>();
        List<Works> array4 = new ArrayList<>();


            List<Work> workList = workDao.SelectByPid(0);
        map.put("1", workList);
            for (Work p1 : workList) {
                List<Workshop> workshopList = workshopDao.SelectByPid(p1.getId());
                //key为2是否有值
                array2.addAll(workshopList);
                for (Workshop p2 : workshopList) {
                    List<Worker> workerList = workerDao.SelectByPid(p2.getId());
                    array3.addAll(workerList);
                    for (Worker p3 : workerList) {

                        List<Works> worksList = worksDao.SelectByPid(p3.getId());
                        array4.addAll(worksList);

                    }
                }
            }
        map.put("2", array2);
        map.put("3", array3);
        map.put("4", array4);

    }

}

这是一种很傻逼的方式···千万不要学我，没有考虑到方便。

今日问题：

接口的实现方法，设计的极差。

明日想法：

别说了，以最快的速度重写任务三，我佛了。
