如何在測試中啓用Spring的自動配置報告？

Question

我剛發現Spring有一個調試模式，它提供了有關自動配置的見解。對於服務器，可以通過將--debug作爲應用程序參數進行啓用。

有沒有辦法啓用調試模式也用於測試（用SpringJUnit4ClassRunner執行）？

如果自動配置報告工作，它應該打印輸出一些像這樣的：

========================= 
AUTO-CONFIGURATION REPORT 
=========================

--debug設置一個debug財產然後在自動配置交換機的報告。您可以在您的測試中使用例如@TestPropertySource對您的測試類進行相同的測試：

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringApplicationConfiguration(Application.class) 
@TestPropertySource(properties = "debug=true") 
public class YourTests { 
    // … 
}
