Eclipse 在Maven测试中读取属性文件
这似乎是一个愚蠢的问题，但我在网上找到的任何解决方案都不适合我。我正在一个Maven项目中编写一个集成测试，需要从属性文件中读取值，我把它放在Eclipse 在Maven测试中读取属性文件,eclipse,maven,integration-testing,Eclipse,Maven,Integration Testing,这似乎是一个愚蠢的问题，但我在网上找到的任何解决方案都不适合我。我正在一个Maven项目中编写一个集成测试，需要从属性文件中读取值，我把它放在src/test/resources中 我的测试在构造期间尝试读取此属性文件： public ControllerIT() throws Exception { wc = new WebConversation(); prop = new Properties(); InputStream stream = getClass().getReso
src/test/resourcespublic ControllerIT() throws Exception {
wc = new WebConversation();
prop = new Properties();
InputStream stream = getClass().getResourceAsStream( "/test.properties" );
prop.load( stream );
}
prop.load（stream）时得到NullPointerException
我已经尝试了我在网上找到的各种解决方案：
- 将文件引用为
test.properties
而不是/test.properties
- 通过
getClass（）.getClassLoader（）.getResourceAsStream（“test.properties”）获取输入流
但什么都不管用
另外，我想理想的解决方案将允许我通过CLI上的mvn集成测试运行此测试，以及在Eclipse中通过runas
->JUnit测试运行此测试。为此，我想我还应该提到，我已经在Eclipse中显式地添加了main/test/resources
作为源文件夹，但它仍然没有正确加载文件
根据要求，这是我的POM：

在这个输出中，ControllerIT
的第30行是对prop.load（inputstream）
的调用，您的项目是打包类型pom。这样，资源插件就不包括在生命周期中（并且不会将任何资源复制到目标，从而进入类路径）
将您的打包更改为jar
，一切都应该正常。请显示完整的pom文件和toue属性文件的位置。如何开始集成测试？您是否使用mvn verify
？添加了POM和maven输出。似乎与此相关：[INFO]无法在存储库libs版本中找到资源“junit:junit:POM:debian”(http://artifactory:8081/artifactory/libs-发行版）下载：http://artifactory:8081/artifactory/simple/vm/junit/junit/debian/junit-debian.pom
？哈！当我第一次遇到这个问题时，我最初使用的是jar
的包装。我将其更改为pom
，因为我不希望它尝试运行单元测试（因为没有单元测试）。看起来我没有使用带有类加载器和/或属性文件路径正确组合的jar
包。
