员工管理系统（SpringBoot+Mybatis+Thymeleaf）

项目代码：gitee github
项目地址：EmployeeManagement

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

</dependencies>

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 {

    @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

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/**");
    }
}
