在Maven測試中讀取屬性文件

Question

這似乎是一個如此愚蠢的問題，但我在網上找到的解決方案並沒有解決我的問題。我在Maven項目中編寫了一個集成測試，我需要從屬性文件中讀取值，我已經把它放在了src/test/resources。

我的測試嘗試讀取施工期間這個屬性文件：

public ControllerIT() throws Exception { 
    wc = new WebConversation(); 
    prop = new Properties(); 
    InputStream stream = getClass().getResourceAsStream("/test.properties"); 
    prop.load(stream); 
} 

當我運行測試，我總是在電話會議中prop.load(stream);得到了NullPointerException。通過getClass().getClassLoader().getResourceAsStream("test.properties");

• 引用該文件作爲test.properties而不是/test.properties
• 獲取輸入流：

  我已經嘗試了關於解決方案的每一個排列，我已經在網上找到但沒有任何工作。

  我想加分，理想的解決方案將允許我通過CLI上的mvn integration-test以及通過Run As - >JUnit test在Eclipse中運行此測試。爲此，我想我還應該提及，我已經明確將main/test/resources添加爲Eclipse中的源文件夾，但它仍然沒有正確加載文件。

  按要求，這裏是我的POM：

  正如你可以看到，這是一個獨立的集成測試套件（它基本上只是發送POST請求的Web服務）。我mvn verify運行它，看看：

  在此輸出，線路的ControllerIT 30是調用prop.load(inputstream)。

您的項目是包裝類型的pom。這樣一來，資源，插件不包含在生命週期中（沒有資源將被複制到目標，從而在classpath地）

您的包裝更改爲jar，一切都應該工作。
