mybatis的配置

1.pom.xml的配置

     com.baomidou
     mybatis-plus-boot-starter
     3.4.3.3

2.编写repository和xml

DeviceDictionaryRepository.java

public interface DeviceDictionaryRepository extends baseMapper {

    
    List queryAll();

}

DeviceDictionaryMapper.xml（注意修改namespace和resultMap中的type）

    
        
        
        
    

    
        select id,type_code,dict_name from device_dict_item
    

3.在启动类上配置@MapperScan

@SpringBootApplication(scanbasePackages = {"com.hikvision.ga.common.boot", "org.example"})
@MapperScan({"mapper","org.example.modules.repository"})
public class Bootstrap {
  
  public static void main(String[] args) {
    SpringApplication.run(Bootstrap.class, args);
  }

}
