Spring：运行多个“SpringApplication.Run（）”在应用主要方法 [英] Spring: Run multiple "SpringApplication.Run()" in application main method

问题描述

嘿，我是Spring的新手，我正在尝试在Applications.java的main中运行多个run方法。

Hey I am new to spring and am trying to run multiple run methods in the main in my Applications.java.

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan
@EnableAutoConfiguration
public class Application {

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

当我尝试运行时，我得到一个例外。

When I try to run this I get an exception.

有没有办法在主要方法中调用两种运行方法？

Is there a way to call both run methods in the main?

推荐答案

我认为您尝试使用两种配置运行一个spring应用程序。

I think you try to run one spring application with two configurations.

通常的方法是使用 @Import 注释。

The normal way to do this is to use the @Import annotation.

@ComponentScan
@EnableAutoConfiguration
@Import(ScheduledTasks.class)
public class Application {

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

@See 春天参考章节4.12.5编写基于Java的配置
使用@Import注释
