Spring:在应用程序主方法中运行多个“ SpringApplication.Run()”

spring-boot

嘿,我是Spring的新手,正在尝试在Applications.java的主目录中运行多个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);
    }
}

当我尝试运行此程序时,出现异常。

有没有一种方法可以同时调用两个run方法?

我认为您尝试使用两种配置运行一个spring应用程序。

通常的方法是使用@Import注释。

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

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

@See
Spring参考第4.12.5章使用@Import批注组合基于Java的配置
