SpringBoot集成mybatis

SpringBoot集成mybatis

1、maven依赖：

<!-- https://mvnrepository.com/artifact/org.mybatis.spring.boot/mybatis-spring-boot-starter -->
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.2</version>
</dependency>

2、yml配置 

#mybatis的相关配置
mybatis:
  #mapper配置文件
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.zhg.demo.mybatis.entity
  #开启驼峰命名
  configuration:
    map-underscore-to-camel-case: true

3、在 Spring Boot 启动类中添加 @MapperScan 注解，扫描 Mapper / dao文件夹：

@SpringBootApplication
@MapperScan("com.dw.study.mapper")
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(QuickStartApplication.class, args);
    }

}

mybatis.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="">
 
</mapper>
