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

# 员工管理系统（SpringBoot+Mybatis+Thymeleaf） 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 ```sql CREATE DATABASE `employee`; USE `employee`; ``` 创建登陆用户数据表 ```sql 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 ```sql 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 ```sql 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', '[email protected]', 0, 1, '2020-05-12'); INSERT INTO `employee` VALUES (2, '李四', '[email protected]', 1, 2, '2020-05-05'); INSERT INTO `employee` VALUES (3, '王五', '[email protected]', 0, 3, '2020-05-15'); INSERT INTO `employee` VALUES (4, '赵六', '[email protected]', 1, 4, '2020-04-21'); INSERT INTO `employee` VALUES (5, '田七', '[email protected]', 0, 3, '2020-05-14'); INSERT INTO `employee` VALUES (10, '王伟', '[email protected]', 1, 3, '2020-05-08'); INSERT INTO `employee` VALUES (11, '张伟', '[email protected]', 1, 2, '2020-05-11'); INSERT INTO `employee` VALUES (12, '李伟', '[email protected]', 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 ```xml <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.2</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> ``` 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 ```yml 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 ```java 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 { @Autowired DataSource dataSource; @Test void 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 1. 创建User实体 ```java 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; } ``` 2. 创建Department实体 ```java 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; } ``` 3. 创建Employee实体 ```java 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; } ``` 4. 创建EmployeeDTO实体 ```java 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; } ``` #### Mapper层 文件存放目录： com.godfrey.mapper 相关接口 resources/com.godfrey.mapper 相关mapper.xml 1. 编写User的Mapper接口：UserMapper ```java package com.godfrey.mapper; import com.godfrey.pojo.User; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.springframework.stereotype.Repository; /** * description : 登录验证查询Mapper * * @author godfrey * @since 2020-05-26 */ @Mapper @Repository public interface UserMapper { User selectPasswordByName(@Param("userName") String userName, @Param("password") String password); } ``` 2. 编写接口对应的Mapper.xml文件：UserMapper.xml ```xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.godfrey.mapper.UserMapper"> <select id="selectPasswordByName" resultType="User"> select * from employee.user where user_name = #{userName} and password = #{password}; </select> </mapper> ``` 3. 编写Department的Mapper接口：DepaertmentMapper ```java pac
