Spring: Run multiple "SpringApplication.Run()" in application main method
提问by user3073234
Hey I am new to spring and am trying to run multiple run methods in the main in my Applications.java.
嘿，我是 spring 的新手，我试图在我的 Applications.java 的 main 中运行多个 run 方法。
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);
}
}
When I try to run this I get an exception.
当我尝试运行它时，出现异常。
Is there a way to call both run methods in the main?
有没有办法在 main 中调用两个 run 方法？

I think you try to run one spring application with two configurations.
我认为您尝试使用两种配置运行一个 spring 应用程序。
The normal way to do this is to use the @Importannotation.
执行此操作的正常方法是使用@Import注释。
@ComponentScan
@EnableAutoConfiguration
@Import(ScheduledTasks.class)
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
@See Spring Reference Chapter 4.12.5 Composing Java-based configurations Using the @Import annotation

Without seeing the code it's not possible to say, but my guess is you are trying to launch 2 webapps with the same port. You can change the port of one if them, or make it a non webapp. I recommend using SpringApplicationBuilderto set those things up.
没有看到代码就不可能说，但我的猜测是您正在尝试使用相同的端口启动 2 个 web 应用程序。您可以更改其中一个的端口，或者使其成为非 Web 应用程序。我建议使用SpringApplicationBuilder来设置这些东西。

the run method supports an array of Objects. This code works
run 方法支持对象数组。此代码有效
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) {
Object[] sources = {Application.class, ScheduledTasks.class};
SpringApplication.run(sources, args);
}
}
