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

1. 新建Spring项目， 添加Lombok，Spring Web，Thymeleaf，Mybatis，MySQL Driver的支持

2. 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

3. 建立基本结构和配置框架

com/
|-- godfrey |-- config |-- controller |-- dto |-- mapper |-- pojo |-- service

4. 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

5. 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

Controller层

1. 登陆页LoginController

   package com.godfrey.controller;

   import com.godfrey.pojo.User;
   import com.godfrey.service.UserService;
   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 org.springframework.web.bind.annotation.RequestParam;

   import javax.servlet.http.HttpSession;

   /**

   • description : 登录Controller

   • @author godfrey

     session.setAttribute(“username”,user.getUserName());
     //登录成功！防止表单重复提交，我们重定向
     return “redirect:/main.html”;
     }else {
     //登录失败！存放错误信息
     model.addAttribute(“msg”,“用户名或密码错误”);
     return “index”;
     }
     }

     @GetMapping(“/user/loginOut”)
     public String loginOut(HttpSession session){
     session.invalidate();
     return “redirect:/index.html”;
     }
     }

2. 员工信息Controller

   package com.godfrey.controller;

   import com.godfrey.dto.EmployeeDTO;
   import com.godfrey.pojo.Department;
   import com.godfrey.pojo.Employee;
   import com.godfrey.service.DepartmentService;
   import com.godfrey.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.PathVariable;
   import org.springframework.web.bind.annotation.PostMapping;

   import java.util.Collection;

   /**

   • description : EmployeeController

   • @author godfrey

   • @since 2020-05-26
     */
     @Controller
     public class EmployeeController {

     @Autowired
     private EmployeeService employeeService;

     @Autowired
     private DepartmentService departmentService;

     //查询所有员工，返回列表页面
     @GetMapping(“/emp”)
     public String list(Model model){
     Collection employees = employeeService.selectAllEmployeeDTO();
     // 将结果放在请求中
     model.addAttribute(“emps”,employees);
     return “emp/list.html”;
     }

     //to员工添加页面
     @GetMapping(“/add”)

     //查出所有的部门，提供选择
     Collection departments = departmentService.selectAllDepartment();
     model.addAttribute(“departments”,departments);
     return “emp/add.html”;
     }

     //员工添加功能，使用post接收
     @PostMapping(“/add”)
     public String add(Employee employee){
     //保存员工信息
     employeeService.addEmployee(employee);
     //回到员工列表页面，可以使用redirect或者forward
     return “redirect:/emp”;
     }

     //to员工修改页面
     @GetMapping(“/emp/{id}”)
     public String toUpdateEmp(@PathVariable(“id”) Integer id, Model model){
     //根据id查出来员工
     Employee employee = employeeService.selectEmployeeById(id);
     //将员工信息返回页面
     model.addAttribute(“emp”,employee);
     //查出所有的部门，提供修改选择
     Collection departments = departmentService.selectAllDepartment();
     model.addAttribute(“departments”,departments);

      return "emp/update.html";

     }

     @PostMapping(“/updateEmp”)
     public String updateEmp(Employee employee){
     employeeService.updateEmployee(employee);
     //回到员工列表页面
     return “redirect:/emp”;
     }

     @GetMapping(“/delEmp/{id}”)
     public String deleteEmp(@PathVariable(“id”)Integer id){
     //根据id删除员工
     employeeService.deleteEmployee(id);
     return “redirect:/emp”;
     }
     }

完善Config文件

1. 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
   • @author godfrey
   • @since 2020-05-26
     */
     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;
     }
     }
     }

2. 编写国际化配置文件

   package com.godfrey.config;

   import org.springframework.util.StringUtils;
   import org.springframework.web.servlet.LocaleResolver;

   import javax.servlet.http.HttpServletRequest;
   import javax.servlet.http.HttpServletResponse;
   import java.util.Locale;

   /**

   • description : 国际化语言解析器

   • @author godfrey

   • @since 2020-05-26
     */
     public class MyLocaleResolver implements LocaleResolver {
     //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) {

     }
     }

3. 编写WebMvc文件，将上述配置到MvcConfiguration中

   package com.godfrey.config;

   import org.springframework.context.annotation.Bean;
   import org.springframework.context.annotation.Configuration;
   import org.springframework.web.servlet.LocaleResolver;
   import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
   import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
   import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

   /**

   • description : 扩展MVC配置

   • @author godfrey

   • @since 2020-05-26
     */
     @Configuration
     public class MyWebMvcConfig implements WebMvcConfigurer {
     @Override
     public void addViewControllers(ViewControllerRegistry registry) {
     registry.addViewController(“/”).setViewName(“index”);
     registry.addViewController(“/index.html”).setViewName(“index”);
     registry.addViewController(“/main.html”).setViewName(“main”);
     }

     //自定义国际化组件
     @Bean
     public LocaleResolver localeResolver(){
     return new MyLocaleResolver();
     }

     @Override
     public void addInterceptors(InterceptorRegistry registry) {
     registry.addInterceptor(new MyHandlerInterceptor())
     .addPathPatterns(“/“)
     .excludePathPatterns(”/“,”/index.html”,“/login”,”/css/”,“/js/“,”/img/”);
     }
     }
