毕业设计——基于SpringBoot+Mybatis+Thymeleaf架构实现的员工管理系统（源码+数据库）

完整项目地址：https://download.csdn.net/download/lijunhcn/88430276

基于SpringBoot+Mybatis+Thymeleaf架构实现的员工管理系统（源码+数据库）

SpringBoot整合CRUD实现员工管理案例，将Mybatis整合到原项目中，加入了数据库，添加了日期选项的控件。

环境要求

JDK8以上
IDEA
MySQL8
Maven3
需要熟练掌握MySQL数据库，SpringBoot及MyBatis知识，简单的前端知识；

数据库环境

创建案例所使用的数据库

CREATE DATABASE `employee`;USE `employee`;

创建登陆用户数据表

DROP TABLE IF EXISTS `user`;CREATE TABLE `user` (`id` int(10) NOT NULL,`user_name` varchar(255)NOT NULL COMMENT '用户名',`password` varchar(255)NOT NULL COMMENT '密码',PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8 ;INSERT INTO `user` VALUES (1, 'admin', '123456');

创建部门信息的数据库表

DROP TABLE IF EXISTS `department`;CREATE TABLE `department` (`id` int(10) NOT NULL,`department_name` varchar(255)NOT NULL COMMENT '部门名称',PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=utf8;BEGIN;INSERT INTO `department` VALUES (1, '市场部');INSERT INTO `department` VALUES (2, '技术部');INSERT INTO `department` VALUES (3, '销售部');INSERT INTO `department` VALUES (4, '客服部');INSERT INTO `department` VALUES (5, '公关部');COMMIT;

创建存放员工信息的数据库表

DROP TABLE IF EXISTS `employee`;CREATE TABLE `employee` (`id` int(10) NOT NULL AUTO_INCREMENT,`employee_name` varchar(255)NOT NULL COMMENT '员工姓名',`email` varchar(255)NOT NULL COMMENT '员工邮箱',`gender` int(2) NOT NULL COMMENT '员工性别',`department_id` int(10) NOT NULL COMMENT '部门编号',`date` date NOT NULL COMMENT '入职日期',PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=13 DEFAULT CHARSET=utf8;BEGIN;INSERT INTO `employee` VALUES (1, '张三', 'zhangsan@gmail.com', 0, 1, '2020-05-12');INSERT INTO `employee` VALUES (2, '李四', 'lisi@qq.com', 1, 2, '2020-05-05');INSERT INTO `employee` VALUES (3, '王五', 'wangwu@126.com', 0, 3, '2020-05-15');INSERT INTO `employee` VALUES (4, '赵六', 'zhaoliu@163.com', 1, 4, '2020-04-21');INSERT INTO `employee` VALUES (5, '田七', 'tianqi@foxmail.com', 0, 3, '2020-05-14');INSERT INTO `employee` VALUES (10, '王伟', 'wangwei@gmail.com', 1, 3, '2020-05-08');INSERT INTO `employee` VALUES (11, '张伟', 'zhangwei@gmail.com', 1, 2, '2020-05-11');INSERT INTO `employee` VALUES (12, '李伟', 'liwei@gmail.com', 1, 3, '2020-05-18');COMMIT;

基本环境搭建

新建Spring项目，添加Lombok，Spring Web，Thymeleaf，Mybatis，MySQL Driver的支持
相关的pom依赖
org.springframework.boot spring-boot-starter-thymeleaf org.springframework.boot spring-boot-starter-web org.mybatis.spring.boot mybatis-spring-boot-starter 2.1.2 mysql mysql-connector-java runtime org.projectlombok lombok true org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine
建立基本结构和配置框架

application.yml里配置数据库连接信息及Mapper映射文件信息
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/employee?useSSL=true&useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8
username: employee
password: employee123
thymeleaf:
cache: false
messages:
basename: i18n.login
mybatis:
type-aliases-package: com.godfrey.pojo
mapper-locations: classpath:com.godfrey.mapper/*Mapper.xml
configuration:
map-underscore-to-camel-case: true
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

测试数据库连接

package com.godfrey;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;

@SpringBootTest
class ApplicationTests {

@AutowiredDataSource dataSource;@Testvoid contextLoads() throws SQLException {System.out.println("数据源>>>>>>" + dataSource.getClass());Connection connection = dataSource.getConnection();System.out.println("连接>>>>>>>>>" + connection);System.out.println("连接地址>>>>>" + connection.getMetaData().getURL());connection.close();}

}

查看输出结果，数据库配置ok

创建pojo实体类

创建User实体
package com.godfrey.pojo;
import lombok.Data;
/**
- description : 登录验证实体类
- @author godfrey
- @since 2020-05-26
  */
  @Data
  public class User {
  private Integer id;
  private String userName;
  private String password;
  }
创建Department实体
package com.godfrey.pojo;
import lombok.Data;
/**
- description : 部门实体类
- @author godfrey
- @since 2020-05-26
  */
  @Data
  public class Department {
  private Integer id;
  private String departmentName;
  }
创建Employee实体
package com.godfrey.pojo;
import lombok.Data;
import java.sql.Date;
/**
- description : 员工实体类
- @author godfrey
- @since 2020-05-26
  */
  @Data
  public class Employee {
  private Integer id;
  private String employeeName;
  private String email;
  private Integer gender; //0:女 1:男
  private Date date;
  private Integer departmentId;
  }
创建EmployeeDTO实体
package com.godfrey.dto;
import lombok.Data;
import java.sql.Date;
/**
- description : EmployeeDTO
- @author godfrey
- @since 2020-05-26
  */
  @Data
  public class EmployeeDTO {
  private Integer id;
  private String employeeName;
  private String email;
  private Integer gender;
  private String departmentName;
  private Date date;
  }

文件存放目录：

com.godfrey.mapper 相关接口

resources/com.godfrey.mapper 相关mapper.xml

编写User的Mapper接口：UserMapper

  */
  @Mapper
  @Repository
  public interface UserMapper {
  User selectPasswordByName(@Param(“userName”) String userName, @Param(“password”) String password);
  }
编写接口对应的Mapper.xml文件：UserMapper.xml
select * from employee.user where user_name = #{userName} and password = #{password};
编写Department的Mapper接口：DepaertmentMapper
package com.godfrey.mapper;
import com.godfrey.pojo.Department;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

  */
  @Mapper
  @Repository
  public interface DepartmentMapper {
  List selectAllDepartment();
  }
编写接口对应的Mapper.xml文件：DepaertmentMapper.xml
select * from department;
编写Employee的Mapper接口：EmployeeMapper

  //添加一个员工信息
  int addEmployee(Employee employee);
  //修改一个员工信息
  int updateEmployee(Employee employee);
  //根据id删除员工信息
  int deleteEmployee(@Param(“id”) Integer id);
  }

编写接口对应的Mapper.xml文件：EmployeeMapper.xml

select e.id, e.employee_name, e.email, e.gender, d.department_name, e.datefrom employee e, department dwhere e.department_id = d.id;select *from employeewhere id = #{id}insert into employee (id, employee_name, email, gender, department_id, date)values (#{id}, #{employeeName}, #{email}, #{gender}, #{departmentId}, #{date})update employeeset employee_name=#{employeeName},email=#{email},gender=#{gender},department_id=#{departmentId},date=#{date}where id = #{id}deletefrom employeewhere id = #{id}

完善Config文件

编写Interceptor拦截器配置
package com.godfrey.config;
import org.springframework.web.servlet.HandlerInterceptor;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
- description : Interceptor登录拦截器

  public class MyHandlerInterceptor implements HandlerInterceptor {
  @Override
  public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
  Object username = request.getSession().getAttribute(“username”);
  if (username == null) {//未登录，返回登录页面
  request.setAttribute(“msg”, “没有权限,请先登录”);
  request.getRequestDispatcher(“/index.html”).forward(request, response);
  return false;
  } else {//登录，放行
  return true;
  }
  }

  //解析请求
  @Override
  public Locale resolveLocale(HttpServletRequest httpServletRequest) {
  //获取请求中的语言参数
  String language = httpServletRequest.getParameter(“lang”);
  Locale locale = Locale.getDefault();//如果没有就使用默认的
  if(!StringUtils.isEmpty(language)){
  String[] split = language.split(“_”);
  locale = new Locale(split[0],split[1]);
  }
  return locale;
  }
  @Override
  public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {
  }
  }
编写WebMvc文件，将上述配置到MvcConfiguration中

  //自定义国际化组件
  @Bean
