为什么我不能在Junit测试中访问src/test/resources ?

I am having a problems running the following code:

我有一个运行以下代码的问题:

configService.setMainConfig("src/test/resources/MainConfig.xml");

From within a Junit @Before method.

从Junit @Before方法。

Is this the way Maven builds out its target folder?

这是Maven构建目标文件夹的方式吗?

Access MainConfig.xml directly. The src/test/resources directory contents are placed in the root of your CLASSPATH.

访问MainConfig。直接xml。src/test/resources目录内容放在类路径的根目录中。

More precisely: contents of src/test/resources are copied into target/test-classes, so if you have the following project structure:

更准确地说:src/test/resources的内容被复制到目标/测试类中，所以如果您有以下项目结构:

.
└── src
    └── test
        ├── java
        │   └── foo
        │       └── C.java
        └── resources
            ├── a.xml
            └── foo
                └── b.xml

It will result with the following test CLASSPATH contents:

它将导致以下测试类路径内容:

/foo/C.class
/ foo / C.class
/a.xml
/ a.xml
/foo/b.xml
/ foo / b.xml

To actually access the files from Java source, use getClass().getResource("/MainConfig.xml").getFile().

要实际访问来自Java源代码的文件，请使用getClass(). getresource(“/MainConfig.xml”). getfile()。

I guess setMainConfig expects the path of a resource, that it will load using the ClassLoader, and not a relative file path. It would help if you linked to the javadoc of this mysterious configService.setMainConfig method.

我猜setMainConfig期望资源的路径，它将使用类加载器加载，而不是相对的文件路径。如果链接到这个神秘的configService的javadoc会有所帮助。setMainConfig方法。

If my guess is correct, then the path should just be MainConfig.xml. Mave copies the contents of src/test/resources to the target/test-classes (IIRC) folder. And this test-classes folder is in the classpath of the unit tests.

如果我的猜测是正确的，那么路径应该是MainConfig.xml。Mave将src/test/resources的内容复制到目标/测试类(IIRC)文件夹中。这个测试类文件夹位于单元测试的类路径中。
