前言
我是歌谣 今天继续带来前后端项目的开发 上次已经开发了部门管理，今天继续开发 员工管理 后端第一步empcontroller代码 package com.itheima.controller; import com.itheima.pojo.Emp; import com.itheima.pojo.PageBean; import com.itheima.pojo.Result; import com.itheima.service.EmpService; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.format.annotation.DateTimeFormat; import org.springframework.web.bind.annotation.*; import java.time.LocalDate; import java.util.List; /** * 员工管理Controller */ @RestController @Slf4j @RequestMapping("/emps") public class EmpController { @Autowired private EmpService empService; @GetMapping public Result page(@RequestParam(defaultValue = "1") Integer page, @RequestParam(defaultValue = "10") Integer pageSize, String name, Short gender, @DateTimeFormat(pattern = "yyyy-mm-dd")LocalDate begin, @DateTimeFormat(pattern = "yyyy-mm-dd")LocalDate end){ log.info("查询分页"); PageBean pageBean=empService.page(page,pageSize,name,gender,begin,end); return Result.success(pageBean); } @DeleteMapping("/{ids}") public Result delete(@PathVariable List ids){ log.info("删除"); empService.delete(ids); return Result.success(); } @PostMapping public Result save(@RequestBody Emp emp){ log.info("新增员工"); empService.save(emp); return Result.success(); } @GetMapping("/{id}") public Result getById(@PathVariable Integer id){ log.info("查询员工"); Emp emp=empService.getById(id); return Result.success(emp); } @PutMapping public Result update(@RequestBody Emp emp){ log.info("修改员工"); empService.update(emp); return Result.success(); } } 复制代码 后端第二步 empservice层 package com.itheima.service; import com.itheima.pojo.Emp; import com.itheima.pojo.PageBean; import org.springframework.stereotype.Service; import java.time.LocalDate; import java.util.List; public interface EmpService { PageBean page(Integer page, Integer pageSize, String name, Short gender, LocalDate begin,LocalDate end); void delete(List ids); void save(Emp emp); Emp getById(Integer id); void update(Emp emp); Emp login(Emp emp); } 复制代码 后端第三步empserviceImpl类 package com.itheima.service.impl; import com.github.pagehelper.Page; import com.github.pagehelper.PageHelper; import com.github.pagehelper.autoconfigure.PageHelperAutoConfiguration; import com.itheima.mapper.EmpMapper; import com.itheima.pojo.Emp; import com.itheima.pojo.PageBean; import com.itheima.service.EmpService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.time.LocalDate; import java.time.LocalDateTime; import java.util.List; //@Service //public class EmpServiceImpl implements EmpService { // @Autowired // private EmpMapper empMapper; // @Override // public PageBean page(Integer page, Integer pageSize) { // Long count= empMapper.count(); // Integer start=(page-1)*pageSize; // empMapper.page(start,pageSize); // List empList=empMapper.page(start,pageSize); // PageBean pageBean=new PageBean(count,empList); // return pageBean; // } //} @Service public class EmpServiceImpl implements EmpService { @Autowired private EmpMapper empMapper; @Override public PageBean page(Integer page, Integer pageSize, String name, Short gender, LocalDate begin, LocalDate end) { PageHelper.startPage(page,pageSize); List empList = empMapper.list(name,gender,begin,end); Page p= (Page) empList; PageBean pageBean=new PageBean(p.getTotal(),p.getResult()); return pageBean; } @Override public void delete(List ids){ empMapper.delete(ids); } @Override public void save(Emp emp) { emp.setCreateTime(LocalDateTime.now()); emp.setUpdateTime(LocalDateTime.now()); empMapper.insert(emp); } @Override public Emp getById(Integer id) { return empMapper.getById(id); } @Override public void update(Emp emp) { emp.setUpdateTime(LocalDateTime.now()); empMapper.update(emp); } @Override public Emp login(Emp emp) { return empMapper.getByUsernameAndPassword(emp); } } 复制代码 后端第四步empmapper package com.itheima.mapper; import com.itheima.pojo.Emp; import org.apache.ibatis.annotations.Insert; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Select; import java.time.LocalDate; import java.util.List; /** * 员工管理 */ //@Mapper //public interface EmpMapper { // @Select("select count(*) from emp") // public Long count(); //@Select("select * from emp limit #{start},#{pageSize}") // public List page(Integer start, Integer pageSize); //} @Mapper public interface EmpMapper { // @Select("select * from emp") public List list(String name, Short gender, LocalDate begin, LocalDate end); void delete(List ids); @Insert("insert into emp(username,name,gender,image,job,entrydate,dept_id,create_time,update_time)"+ "values(#{username},#{name},#{gender},#{image},#{job},#{entrydate},#{deptId},#{createTime},#{updateTime})") void insert(Emp emp); @Select("select * from emp where id=#{id}") Emp getById(Integer id); void update(Emp emp); @Select("select * from emp where username=#{username} and password=#{password}" ) Emp getByUsernameAndPassword(Emp emp); } 复制代码 实现结果 查询我是歌谣 放弃很容易 但是坚持一定很酷 一名研究java和前端的程序员 想加入前端巅峰人才交流群联系我 |
