Spring，使用新的 ClassPathXmlApplicationContext 并出现无法找到 applicationContext.xml 和其他人的错误? [英] Spring, using new ClassPathXmlApplicationContext and getting error being unable to find applicationContext.xml and others?

问题描述

我正在尝试学习本教程:http://www.vogella.de/article/SpringDependencyInjection/article.html 在我的应用程序中使用注解依赖注入.我在教程中设置了 bean 等，然后尝试在我的 MainController 类中获取 bean 的一个实例(一个处理为我的 spring web mvc 应用程序生成特定页面的控制器类).我不断得到

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 MainController 中执行此操作:

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();

我对此进行了搜索和搜索，但仍未找到解决我问题的答案.我在 webapp/WEB-INF/中的 applicationContext 和我的 spring 应用程序似乎正在以其他方式工作，因为它在此之前处理请求等.我试过将 applicationContext.xml 放在 WEB-INF 类中，但仍然没有.有什么解决方法可以使它不以这种方式搜索路径，因为我认为它在进行相对路径搜索.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

不是直接的答案，但在这里.

Not a direct answer, but here goes.

您参考的教程是针对独立应用程序而非 Web 应用程序中的依赖项注入的.对于 Web 应用程序，spring 会自动加载上下文文件并初始化 bean.因此，您不需要 MainController 中指定的任何行.

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来在你的控制器中使用 beanIRPlus bean.

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

@Autowired
private BeanIRPlus beanIRPlus;
