SpringApplication.run主要方法 [英] SpringApplication.run main method

问题描述

我使用Spring Starter项目模板在Eclipse中创建了一个项目。

I created a project in Eclipse using the Spring Starter project template.

它自动创建了一个Application类文件，该路径与POM.xml中的路径匹配文件，所以一切都很好。这是Application类：

It automatically created an Application class file, and that path matches the path in the POM.xml file, so all is well. Here is the Application class:

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

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

这是我正在构建的命令行应用程序为了让它运行我必须注释掉SpringApplication.run行，只需从我的其他类中添加main方法即可运行。
除了这个快速的jerry-rig之外，我可以使用Maven构建它，并且它作为Spring应用程序运行，类似于。

This is a command line app that I am building and in order to get it to run I had to comment out the SpringApplication.run line and just add the main method from my other class to run. Other than this quick jerry-rig, I can build it using Maven and it runs as a Spring application, sort of.

我宁愿，但是，不必注释掉那一行，并使用完整的Spring框架。我该怎么做？

I'd rather, however, not have to comment out that line, and use the full Spring framework. How can I do this?

推荐答案

你需要运行 Application.run（）因为这个方法启动整个Spring Framework。下面的代码将您的 main（）与Spring Boot集成。

You need to run Application.run() because this method starts whole Spring Framework. Code below integrates your main() with Spring Boot.

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application {

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

ReconTool.java

ReconTool.java

@Component
public class ReconTool implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        main(args);
    }

    public static void main(String[] args) {
        // Recon Logic
    }
}

为什么不 SpringApplication.run（ReconTool.class，args）

因为这样弹簧没有完全配置（没有组件扫描等）。只创建run（）中定义的bean（ReconTool）。

Why not SpringApplication.run(ReconTool.class, args)

Because this way spring is not fully configured (no component scan etc.). Only bean defined in run() is created (ReconTool).
