Store xml files in resources folder (WAR), read from code
提问by JavaPete
I have different XML-files in my 'src/main/recources' folder, and I'd like to read them from my webapplication.
我的“src/main/resources”文件夹中有不同的 XML 文件，我想从我的 web 应用程序中读取它们。
File f = new File("file1.xml");
f.getAbsolutePath();
The code gets invoked inside a WebService, and this prints out 'C:\Users\Administrator' when I look inside the Tomcat-server-output. My current solution is to put the 'file1.xml'-documents outside of the WAR, in the 'C:\'-folder but this way my WAR is not transferable.
该代码在 WebService 内被调用，当我查看 Tomcat-server-output 时，它会打印出“C:\Users\Administrator”。我当前的解决方案是将 'file1.xml'-documents 放在 WAR 之外的 'C:\'-文件夹中，但这样我的 WAR 就不可转移。
I've also tried
我也试过
<bean name="webService">
<property name="document">
<value>classpath:file1.xml</value>
</property>
</bean>
But that just prints out the "classpath:file.xml" without parsing it.
但这只是打印出“classpath:file.xml”而不解析它。

If you are using the standard maven2 war packaging, your file1.xml is copied to the directory WEB-INF/classes within your warfile.
如果您使用标准的 maven2 war 打包，您的 file1.xml 将被复制到您的 warfile 中的目录 WEB-INF/classes。
You can access this file via the classpath.
您可以通过类路径访问此文件。
URL resourceUrl = URL.class.getResource("/WEB-INF/classes/file1.xml");
File resourceFile = new File(resourceUrl.toURI());

If you put the file in a directory underneath WEB-INF (or within WEB-INF itself) then you can read it using the ServletContext's getResourceAsStreammethod:
如果您将文件放在 WEB-INF 下（或 WEB-INF 本身内）的目录中，则可以使用ServletContext'sgetResourceAsStream方法读取它：
try {
InputStream is = context.getResourceAsStream("/WEB-INF/file1.xml");
...
} catch (IOException e) {
...
}

You can put the path info in the properties file that is in the path /WEB-INF/classes - and load this info in the application at runtime.
您可以将路径信息放在路径 /WEB-INF/classes 中的属性文件中 - 并在运行时将此信息加载到应用程序中。
To have different value for this path property you can use the option of maven profiles or any other build tool - so that different environment results in the WAR file having the right properties value for the path suited for that environment.
要为此路径属性设置不同的值，您可以使用 maven 配置文件或任何其他构建工具的选项 - 这样不同的环境会导致 WAR 文件具有适合该环境的路径的正确属性值。
