Start-Class: 应用的启动类

Main-Class: org.springframework.boot.loader.JarLauncher

SpringBoot打成jar包后,真正的jar启动类是{@link JarLauncher}, 通过反射调用应用启动类的main(String[] args), 实则如果SpringBoot定义应用启动类的启动方法也是可以的
@see ExecutableArchiveLauncher#getMainClass()
@see MainMethodRunner#run()

 <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-loader</artifactId>
      <scope>provided</scope>
 </dependency>

远程调试

  1. 应用打成jar包,通过远程调试应用启动命令启动应用
  2. idea中创建remote,设置远程连接参数,见图片springboot-loader-debug.png
