春天，使用新的ClassPathXmlApplicationContext和得到错误是无法找到的applicationContext.xml和其他人？ [英] Spring, using new ClassPathXmlApplicationContext and getting error being unable to find applicationContext.xml and others?

问题描述

我想按照这个教程： http://www.vogella.de/文章/ SpringDependencyInjection / article.html 使用注释依赖注入我的应用程序。我成立了绿豆等像教程，然后我试图我MainController类（处理产生我和Spring Web MVC应用程序特定的页面控制器类）中得到bean的实例。我不断收到

I am trying to follow this tutorial: http://www.vogella.de/articles/SpringDependencyInjection/article.html to use annotation dependency injection in my application. I set up the bean, etc like in the tutorial and then am trying to get an instance of the bean within my MainController class (a controller class that handles generating a specific page for my spring web mvc app).. I keep getting

SEVERE: Servlet.service() for servlet spring threw exception

    java.io.FileNotFoundException: class path resource [WEB-INF/applicationContext.xml] cannot be opened because it does not exist

我在我的MainController这样做的：

I am doing this in my MainController:

    ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

    BeanFactory factory = context;
    BeanIRPlus beanirPlus = (BeanIRPlus) factory
            .getBean("BeanIRPlus");
    IRPlusInterface irPlus = beanirPlus.getIRPlus();

我已经搜查，搜查就这个问题和尚未找到能解决我的问题的答案。我在的webapp / WEB-INF的applicationContext /和我的春天应用程序似乎是另有工作，因为它是在此之前处理请求，等等。我试图把applicationContext.xml中的WEB-INF类，但仍然一无所获。有任何解决方法，使这个，因为我觉得它做的相对路径搜索无法搜索的路径这种方式。感谢您的任何建议。

I have searched and searched on this and yet to find an answer that fixes my problem. My applicationContext in in webapp/WEB-INF/ and my spring app seems to be working otherwise as it was handling requests, etc before this. I have tried putting the applicationContext.xml in WEB-INF classes but still nothing. Is there any workaround to make this not search the path this way as I think its doing a relative path search. Thanks for any advice

推荐答案

不是一个直接的答案，但在这里不用。

Not a direct answer, but here goes.

您提到的教程是一个独立的应用程序依赖注入，而不是一个Web应用程序。在Web应用程序的情况下，弹簧会自动加载上下文文件并初始化豆。所以，你不需要任何指定的行 MainController 。

The tutorial you have referred is for dependency injection in a standalone application and not a web application. In case of web application, spring automatically loads the context files and initializes the beans. So you would not need any of the lines specified in the MainController.

相反，你可以做这样的事情在你的控制器使用beanIRPlus豆。

Instead, you could do something like this to use beanIRPlus bean in your controller.

@Autowired
private BeanIRPlus beanIRPlus;
