构建数据库

CREATE TABLE `mybatis`.`tbl_emp` (

  `email` VARCHAR(255) NULL,

ALTER TABLE `mybatis`.`tbl_emp` 
ADD COLUMN `d_id` INT NULL AFTER `email`,
ADD INDEX `fk_emp_dept_idx` (`d_id` ASC) VISIBLE;

ALTER TABLE `mybatis`.`tbl_emp` 
ADD CONSTRAINT `fk_emp_dept`
  FOREIGN KEY (`d_id`)
  REFERENCES `mybatis`.`tbl_dept` (`dept_id`)
  ON DELETE CASCADE
  ON UPDATE CASCADE;

使用Mybatis逆向工程

        } catch (Exception e) {
            e.printStackTrace();

写一个测试类插入一些数据

package com.zzf.ssm.test;

/*

 *
 */

import com.zzf.ssm.dao.DepartmentMapper;
import com.zzf.ssm.dao.EmployeeMapper;
import com.zzf.ssm.pojo.Employee;
import org.apache.ibatis.session.SqlSession;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.UUID;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:beans.xml"})
public class MapperTest {

    @Autowired
    DepartmentMapper departmentMapper;

    @Autowired
    EmployeeMapper employeeMapper;

    @Autowired
    SqlSession sqlSession;

    @Test
    public void testCRUD(){
        //插入部门
        /*departmentMapper.insertSelective(new Department(null,"开发部"));
        departmentMapper.insertSelective(new Department(null,"测试部"));*/

        //批量插入
        EmployeeMapper mapper = sqlSession.getMapper(EmployeeMapper.class);
        for (int i = 0; i < 1000; i++) {
            String uid = UUID.randomUUID().toString().substring(0, 5) + i;
            mapper.insertSelective(new Employee(null,uid,"M",uid+"@qq.com",8));
        }
        System.out.println("批量插入完成");
    }
}

构建前端

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<jsp:forward page="/WEB-INF/views/list.jsp"></jsp:forward>

list.jsp

具体见源码

实现的功能

分页查询

添加

删除（单个和批量）

编辑

其中添加和编辑加入了（JSR303后端校验和jquey前端校验）

效果展示

在这里插入图片描述
