简介： 快速搭建员工管理系统

4、员工管理页面

4.1、查询全部员工

DAO层

编写EmployeeMapper

package com.bobooy.ems.mapper;

import com.bobooy.ems.pojo.Employee;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/9/26 23:23
 */
@Mapper
@Repository
public interface EmployeeMapper {
    //查询全体员工信息
    public Collection<Employee> getAll();
}

编写EmployeeMapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.bobooy.ems.mapper.EmployeeMapper">
    <select id="getAll" resultMap="EmployeeDepartment">
        select e.id eid, e.last_Name eName, e.email email, e.gender gender,d.id did,e.birth birth, d.department_name dName
        from employee e
        join department d
        on e.department = d.id
    </select>
    <resultMap id="EmployeeDepartment" type="Employee">
        <result property="id" column="eid"/>
        <result property="lastName" column="eName"/>
        <result property="email" column="email"/>
        <result property="gender" column="gender"/>
        <result property="birth" column="birth"/>
        <association property="department" javaType="Department">
            <result property="id" column="did"/>
            <result property="departmentName" column="dName"/>
        </association>
    </resultMap>
</mapper>

service层

编写EmployeeService

package com.bobooy.ems.service;

import com.bobooy.ems.mapper.EmployeeMapper;
import com.bobooy.ems.pojo.Employee;
import org.springframework.stereotype.Service;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/9/26 23:44
 */
public interface EmployeeService {
    //查询全体员工信息
    public Collection<Employee> getAll();
}

EmployeeServiceImpl

package com.bobooy.ems.service;

import com.bobooy.ems.mapper.EmployeeMapper;
import com.bobooy.ems.pojo.Employee;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/9/26 23:45
 */
@Service
public class EmployeeServiceImpl implements EmployeeService{
    @Override
    public Collection<Employee> getAll() {
        return employeeMapper.getAll();
    }
}

controller层

编写EmployeeContoller

package com.bobooy.ems.controller;

import com.bobooy.ems.mapper.EmployeeMapper;
import com.bobooy.ems.pojo.Employee;
import com.bobooy.ems.service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/9/26 23:20
 */
@Controller
public class EmployeeController {
    @Autowired
    private EmployeeService employeeService;

    @RequestMapping("/emps")
    public String list(Model model) {
        Collection<Employee> employees = employeeService.getAll();
        model.addAttribute("emps",employees);
        return "emp/list";
    }
}

测试

4.2、添加员工

4.2.1、跳转添加页面

DAO层

编写 DepartmentMapper

package com.bobooy.ems.mapper;

import com.bobooy.ems.pojo.Department;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/9/27 0:01
 */
@Mapper
@Repository
public interface DepartmentMapper {
    //获取所有部门的信息
    Collection<Department> getDepartments();

    // 通过ID查询部门
    Department getDepartmentById(Integer id);
}

DepartmentMapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.bobooy.ems.mapper.DepartmentMapper">
    <select id="getDepartments" resultType="Department">
        select * from department
    </select>

    <select id="getDepartmentById" resultType="Department" parameterType="Integer">
        select * from department where id = #{id}
    </select>
</mapper>

在 application.yaml中开启 Myabtis 驼峰命名映射注意空格

  configuration:
    map-underscore-to-camel-case: true #开启驼峰命名

Service层

DepartmentService

package com.bobooy.ems.service;

import com.bobooy.ems.pojo.Department;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/10/2 10:31
 */
public interface DepartmentService {
    //获取所有部门的信息
    Collection<Department> getDepartments();

    // 通过ID查询部门
    Department getDepartmentById(Integer id);
}

DepartmentServiceImpl

package com.bobooy.ems.service;

import com.bobooy.ems.mapper.DepartmentMapper;
import com.bobooy.ems.pojo.Department;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Collection;

/**
 * @author BoBooY
 * @date 2022/10/2 10:32
 */
@Service
public class DepartmentServiceImpl implements DepartmentService{
    @Autowired
    private DepartmentMapper departmentMapper;

    @Override
    public Collection<Department> getDepartments() {
        return departmentMapper.getDepartments();
    }

    @Override
    public Department getDepartmentById(Integer id) {
        return departmentMapper.getDepartmentById(id);
    }
}

Controller层

在EmployeeController中处理 ”/add“请求

@Autowired
private DepartmentService departmentService;    
@GetMapping("/add")
public String add(Model model) {
    Collection<Department> departments = departmentService.getDepartments();
    model.addAttribute("depts",departments);
    System.out.println(departments);
    return "emp/add";
}

测试

在这里插入图片描述

4.2.2、处理添加员工请求

DAO层

编写EmployeeMapper

//添加员工
public int save(Employee employee);

EmployeeMapper.xml

<insert id="save" parameterType="Employee">
    insert into employee(`last_name`, `email`, `gender`, `department`, `birth`)
    values (#{lastName}, #{email}, #{gender}, #{department.id}, #{birth})
</insert>

service层

EmployeeService

//添加员工
public int save(Employee employee);

EmployeeServiceImpl

@Override
public int save(Employee employee) {
    return employeeMapper.save(employee);
}

controller层

EmployeeController

//添加员工
@RequestMapping("/addEmp")
public String addEmp(Employee employee) {
    int save = employeeService.save(employee);
    if(save > 0) {
        System.out.println("添加成功！");
    } else {
        System.out.println("添加失败！");
    }
    return "redirect:/emps";
}

设置日期格式

application.yaml（注意空格）

  #日期格式配置
  mvc:
    format:
      date: yyyy-MM-dd HH:mm

测试：添加员工

成功！

4.3、修改员工

Dao层

编写 EmployeeMapper

//修改员工
public int updateEmployee(Employee employee);

// 通过ID查询员工
public Employee getEmployee(Integer id);

EmployeeMapper.xml

<select id="getEmployee" parameterType="int" resultMap="EmployeeDepartment">
    select e.id eid, e.last_Name eName, e.email email, e.gender gender,d.id did,e.birth birth, d.department_name dName
    from employee e
    join department d
    on e.department = d.id
    where e.id = #{id}
</select>

<update id="updateEmployee" parameterType="Employee">
    update employee set `last_name`=#{lastName},`email`=#{email},`gender`=#{gender},`department`=#{department.id},`birth`=#{birth} where `id` = #{id}
</update>

service层

EmployeeService

// 通过ID查询员工
public Employee getEmployee(Integer id);

//修改员工
public int updateEmployee(Employee employee);

EmployeeServiceImpl

@Override
public Employee getEmployee(Integer id) {
    return employeeMapper.getEmployee(id);
}

@Override
public int updateEmployee(Employee employee) {
    return employeeMapper.updateEmployee(employee);
}

Controller层

EmployeeController

//跳转修改页面
@GetMapping("/update/{id}")
public String update(@PathVariable("id") int id,Model model) {
    Employee employee = employeeService.getEmployee(id);
    model.addAttribute("emp",employee);
    Collection<Department> departments = departmentService.getDepartments();
    model.addAttribute("departments",departments);
    return "emp/update";
}

//修改员工信息
@PostMapping("/updateEmp")
public String update(Employee employee) {
    int update = employeeService.updateEmployee(employee);
    if(update > 0) {
        System.out.println("修改成功");
    }else {
        System.out.println("修改失败");
    }
    return "redirect:/emps";
}

测试：修改id为 1012 的员工部门为后勤部性别为男

4.4、删除员工

Dao层

EmployeeMapper

// 删除员工
public int delete(Integer id);

EmployeeMapper.xml

<delete id="delete" parameterType="int">
    delete from employee where `id` = #{id}
</delete>

service层

EmployeeService

// 删除员工
public int delete(Integer id);

EmployeeServiceImpl

@Override
public int delete(Integer id) {
    return employeeMapper.delete(id);
}

controller层

EmployeeController

//删除员工
@RequestMapping("/delete/{id}")
public String delete(@PathVariable("id") int id) {
    int delete = employeeService.delete(id);
    if(delete > 0)
        System.out.println("删除成功！");
    else {
        System.out.println("删除失败！");
    }
    return "redirect:/emps";
}
