我在Mac 10.7.4上運行Eclipse Indigo。我在Eclipse中設置了Maven(3.0.3)項目,但是當我在Eclipse中運行JUnit測試時,未能在我的src/main/resources目錄中加載屬性文件。然而,在Maven命令行上運行相同的測試通過,所以我想知道我的設置有什麼問題。這裏的測試...未能在Eclipse中加載屬性文件--JUnit測試

@Before 
public void setUp() throws IOException { 
    ... 
    stateService = new StateService("states.properties"); 
    ... 
} // setUp 

@Test 
public void testPositive() { 
    final String stateName = stateService.getStateFromAbbrev("TX"); 
    Assert.assertEquals("Texas", stateName); 
} // testPositive 

這裏就是我如何裝入特性文件...

public StateService(final String propertiesFile) { 
    abbrevToWordsProps = new Properties(); 
    InputStream in = null; 
    try{ 
     in = this.getClass().getClassLoader().getResourceAsStream(propertiesFile); 
     abbrevToWordsProps.load(in); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(System.err); 
    } finally { 
     if (in != null) { 
      try { 
       in.close(); 
      } catch (IOException e) { 
      } 
     } // if 
    } 
} 

當我運行通過Eclipse的測試(在Package Explorer中的Java測試文件上右鍵單擊,然後去Run As - > JUnit Test),它會隨着此例外而死亡...

怎麼回事?

確保'src/main/resources'目錄在您的eclipse JUnit測試類路徑中(請參閱Run configuration -> classpath tab)。

right ...或者運行'mvn eclipse:eclipse'並在項目根目錄上按F5,這是實現完全相同的事情的另一種方法:) – mschonaker

@mschonaker我懷疑混合使用Maven Integration(m2e)與maven-eclipse-plugin。 – FrVaBe

請使用下面的代碼: -

this.getClass().getResourceAsStream(propertiesFile); 

請不要使用 「getClassLoader()」。

我希望這可能有所幫助。

謝謝,這個提示真的幫了我。 – Robert
