SpringBoot-整合Mybatis-xml方式

这里利用SpringBoot整合了Mybatis，本实例主要使用xml方式，接下来会有注解方式，本实例Github地址04-mybatis，废话不多说，接下来开始整合：

POM文件

这是完整的pom文件：

        <!-- SpringBoot Mybatis整合包 -->

            </plugin>
        </plugins>

</project>

其中本次整合关键依赖：

<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<version>5.1.39</version>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>1.3.2</version>
</dependency>

数据库准备

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `name` varchar(50) DEFAULT NULL COMMENT '姓名',
  `age` int(11) DEFAULT NULL COMMENT '年龄',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of user
-- ----------------------------
INSERT INTO `user` VALUES ('1', '张三', '21');
INSERT INTO `user` VALUES ('2', '李四', '23');
INSERT INTO `user` VALUES ('3', '王二', '22');

实体类

Controller

Service接口

Service实现

Mapper接口

Mapper.xml映射

application配置

## 数据源配置
spring.datasource.url=jdbc:mysql://localhost:3306/springboot?characterEncoding=utf8
spring.datasource.username=root
spring.datasource.password=215521
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

## Mybatis 配置
mybatis.typeAliasesPackage=com.perfree.mybatis.pojo.User
mybatis.mapperLocations=classpath:mapper/*.xml

入口配置扫描mapper包

运行

到此简单的SpringBoot整合Mybatis的xml方式算是完成了，整合的时候注意对比文件路径及注解配置，祝你成功~
