java.io.FileNotFoundException: class path resource [WEB-INF/classes/library.properties] cannot be opened because it does not exist
提问by Mr Morgan
In my Spring application, I have a simple properties file located in folder WEB-INF\classesso that it, the DispatcherServletand various other config files are in the classpath.
在我的 Spring 应用程序中，我在文件夹中有一个简单的属性文件，WEB-INF\classes因此它、DispatcherServlet以及其他各种配置文件都在classpath.
The props file is defined in the DispatcherServletas:
props 文件定义DispatcherServlet为：
<bean id="propertiesFactory" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location">
<value>/WEB-INF/classes/library.properties</value>
</property>
</bean>
The propertiesFactorybean is injected into a controller:
该propertiesFactorybean被注入到一个控制器：
@Autowired
private Properties propertiesFactory;
And used in a one of the controller's methods as:
并在控制器的方法之一中用作：
if (adminPassword.equals(propertiesFactory.getProperty("adminPassword"))) {
This all works perfectly, except for a test program as follows which has line:
这一切都完美无缺，除了如下的测试程序，它有一行：
ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("library-servlet.xml");
Which throws a BeanCreationException:
其中抛出一个BeanCreationException：
Injection of autowired dependencies failed
Because of:
因为：
java.io.FileNotFoundException: class path resource [WEB-INF/classes/library.properties] cannot be opened because it does not exist
But if the whole application can see the props file, why not this one program?
但是如果整个应用程序都可以看到 props 文件，为什么不能看到这个程序呢？

Everything in WEB-INF/classesis added to the root of the classpath. As such, you need to refer to your resource simply as
中的所有内容都WEB-INF/classes添加到类路径的根目录中。因此，您需要将您的资源简单地称为
library.properties
or better yet
或者更好
classpath:library.properties
in
在
<property name="location">
<value>classpath:library.properties</value>
</property>
You may find it useful to run
你可能会发现运行它很有用
System.out.println(System.getProperty("java.class.path"));
and see what was used as classpath entries.
并查看用作类路径条目的内容。
