First of all, create a multi-module project to make the project run successfully and run.

You can refer to the article to create a multi-module project, Goodbye!

The project is divided into three sub-modules: parent megatron

Megatron-api

Project startup class

Package com.megatron.module;import com.megatron.utils.IPUtils;import org.mybatis.spring.annotation.MapperScan;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication@MapperScan ("com.megatron.module.dal.mapper") / / scan the interface public class MegatronLogApiApplication {public static Logger logger = LoggerFactory.getLogger (MegatronLogApiApplication.class) in the specified package Public static void main (String [] args) {System.setProperty ("local-ip", IPUtils.getLocalIp ()); SpringApplication.run (MegatronLogApiApplication.class, args);}}
