为什么Maven不包括我的文件/src/main/resources/config.props？

Question

我认为包含在src/main/resources目录中的任何东西都会打包成WAR？

我有以下结构：

src/main/resources/META-INF/... 
src/main/resources/config.props 

的META-INF包括，但config.props不是。我如何将它添加到WAR中？

Answer 1

WAR文件的根目录不是资源，而是src/main/webapp。如果您想在WAR文件中直接在WEB-INF下的文件，请将它们放入src/main/webapp/WEB-INF。 src/main/resources下的资源将在您的WAR文件中以/WEB-INF/classes结尾。

例如，如果你的来源是这样的：

. 
|____ src 
| |____ main 
| | |____ resources 
| | | |____ config.props 
| | |____ webapp 
| | | |____ WEB-INF 
| | | | |_____ web.xml 
| | | |____ index.jsp 

你的WAR文件将是这样的：

. 
|____ WEB-INF 
| |____ classes 
| | |____ config.props 
| |____ web.xml 
|____ index.jsp 

Answer 2

缺省情况下，src/main/resources文件夹的内容在类路径的根copyied。正如Seelenvirtuose指出的那样，对于标准WAR，在WEB-INF/classes文件夹中。

Answer 3

包容的Maven的资源插件文档/排除（这里https://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html）是预先说明一些资源可能不包括在内。您可以查看文档以确保已识别包含的任何非标准资源（例如，* .props不是标准的Java属性文件名）。如果默认设置对您的项目不起作用，您还可以设置源文件夹和目标文件夹。
