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’, ‘[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

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

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

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
创建pojo实体类

  //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);
  }
