springBoot整合Mybatis，Junit

整合Mybatis

 

SpringBoot的版本：2.2.5.RELEASE Mybatis版本：mybatis-spring-boot-starter 2.1.2

 

添加Mybatis的起步依赖

<!-- Mybatis的起步依赖 -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.2</version>
</dependency>

添加数据库的驱动坐标

springBoot自动管理了mysql驱动的坐标，不用自己导入版本

　　

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

添加数据库连接信息，并使用druid连接池

# DBconfiguration：
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
    url: jdbc:mysql://127.0.0.1:3306/test
    type: com.alibaba.druid.pool.DruidDataSource

创建User表

在test数据库中创建表

-- ----------------------------
-- Table structure for `user`
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(50) DEFAULT NULL,
  `password` varchar(50) DEFAULT NULL,
  `name` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', 'zhangsan', '123', '张三');
INSERT INTO `user` VALUES ('2', 'lisi', '123', '李四');

创建实体Bean

package xyz.ytfs.entity;

/**
 * @author by 雨听风说
 * @Classname User
 * @Description TODO(用户的实体)
 * @Date 2020/5/13 15:45
 */


public class User {

    private Integer id;
    private String username;
    private String password;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                ", name='" + name + '\'' +
                '}';
    }
}
