Optimize SpringBoot startup log display

Optimize SpringBoot startup log display

SpringBoot startup class.

package com.course;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
import org.springframework.core.env.Environment;

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    
    

    private static final Logger LOG = LoggerFactory.getLogger(EurekaApplication.class);

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

    public static void main(String[] args) {
    
    
        SpringApplication app = new SpringApplication(EurekaApplication.class);
        Environment env = app.run(args).getEnvironment();
        LOG.info("启动成功！！");
        LOG.info("Eureka地址: \thttp://127.0.0.1:{}", env.getProperty("server.port"));
    }

}

I rewrote the logback.log file and rewritten the output format of the log, such as the time-I changed it to be shorter.
