SpringBoot 集成MyBatis

依赖包

     org.mybatis.spring.boot
     mybatis-spring-boot-starter
     2.1.3

properties配置

#指定xml文件的路径。*是个通配符，代表所有的文件，**代表所有目录下
mybatis.mapperLocations=classpath:mybatis/*Mapper.xml

#开启控制台sql语句打印
mybatis.configuration.log-impl=org.apache.ibatis.logging.slf4j.Slf4jImpl

#指定POJO扫描包来让mybatis自动扫描到自定义的POJO
mybatis.type-aliases-package=com.ocp.bizbase.entity

#该配置就是将带有下划线的表字段映射为驼峰格式的实体类属性
#配置该项后，在开发中只需要根据查询返回的字段，创建好实体类就可以了
mybatis.configuration.map-underscore-to-camel-case=true

启动类配置 注解@MapperScan

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
//import springfox.documentation.oas.annotations.EnableOpenApi;


@SpringBootApplication(scanbasePackages = {"com.test.xxx.*"})
@EnableDiscoveryClient
@MapperScan("mapper接口所在包路径")
public class BizbaseApplication {

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

    @LoadBalanced
    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

}
