Can i configure the Spring MVC application so that when ever i run the application, the controller or any method should be called automatically

问题

我已经开发了一个Spring应用程序,其中包含一个仅将具有一个GET方法的rest控制器。
我能否配置Spring MVC应用程序,以便无论何时我运行该应用程序,控制器或任何方法都会自动被调用,而无需从浏览器中访问API(就像独立应用程序一样)?

英文:

I have developed a spring application with rest controller which will have only one GET method.
Can i configure the Spring MVC application so that when ever i run the application, the controller or any method should be called automatically with out hitting the api from browser(Just like stand alone application)

你可以创建一个实现了 org.springframework.boot.CommandLineRunner 接口的 Bean。

例如:

  1. @Component
  2. public class MyRunner implements CommandLineRunner {
  3. @Override
  4. public void run(String... args) throws Exception {
  5. // 在启动时在这里进行操作
  6. }
  7. }

由于这是一个常规的 Spring 组件,你可以使用字段注入或构造函数注入来注入其他 Spring 组件。

英文:

You can create a bean that implements org.springframework.boot.CommandLineRunner interface.

E.g.

  1. @Component
  2. public class MyRunner implements CommandLineRunner {
  3. @Override
  4. public void run(String... args) throws Exception {
  5. // Do stuff here at startup
  6. }
  7. }

As this is a regular Spring component, you can use field or constructor injection to inject other Spring components.

你可以使用应用程序事件监听器在启动后执行工作。将以下代码添加到您的任何组件中:

  1. @EventListener(ApplicationReadyEvent.class)
  2. public void init(ApplicationReadyEvent ev) {
  3. // 启动后的操作
  4. }

更多信息请参见Application Events and Listeners(应用程序事件和监听器)

英文:

You can use an application event listener to do work after startup. Add this code in any of your components:

  1. @EventListener(ApplicationReadyEvent.class)
  2. public void init( ApplicationReadyEvent ev ) {
  3. //after startup
  4. }
