为什么我的常规应用程序上下文不能加载我的属性文件? [英] Why can't my regular application context load my properties file?

问题描述

我正在尝试在我的应用程序中使用 PropertyPlaceholderConfigurer.我的 applicationContext-test.xml 加载我的属性文件就好了，但我的 applicationContext.xml 抛出异常.在这两种情况下，我都像这样加载我的属性文件:

I'm trying to use the PropertyPlaceholderConfigurer in my application. My applicationContext-test.xml loads my properties file just fine, but my applicationContext.xml throws an exception. In both cases, I'm loading my properties file like this:

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">    
    <property name="location">
        <value>localdevelopment_Company.properties</value>
    </property>
</bean>

当我运行我的测试时，它没有抱怨，但是当我启动我的服务器时，我得到这个异常:

When I run my tests, it does not complain, but when I start my server, I get this exception:

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

为了让它发挥作用，我快把自己逼疯了.有人可以帮忙吗?

I'm driving myself crazy trying to get this to work. Can someone help?

推荐答案

这归结为不同的应用程序上下文在何处寻找其资源.

This comes down to where different application contexts look for their resources.

单元测试上下文查看类路径，而 webapp 上下文查看 webapp 内部.因此，当您的 Web 应用程序查找 localdevelopment_Company.properties 时，它正在查找 Web 应用程序根目录下的文件.

A unit test context looks at the classpath, but a webapp context looks inside the webapp. So when your webapp looks for localdevelopment_Company.properties, it's looking for a file at the root of the webapp.

如果您的文件实际上在类路径上，那么您需要覆盖 webapp 上下文的默认搜索位置:

If your file is actually on the classpath, then you need to override the webapp context's default search location:

<value>classpath:localdevelopment_Company.properties</value>
