PowerMockito和CORBA衝突

Question

我想使用PowerMockito對使用CORBA的第三方庫的項目進行一些測試。我試圖通過找到問題的根源來跳過這個例外。我沒有成功找到關於這件事的信息。

這是我不能使它工作的最簡單的代碼：

Java類

@RunWith(PowerMockRunner.class) 
public class ORBTest { 

    @Test 
    public void initORB() throws Exception { 
     ORB.init(); 
    }  
} 

的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

如果有人，我會感激在這裏可以給我一些啓示，因爲你不知道該怎麼改變才能完成這項工作。

Answer 1

錯誤這樣

java.lang.LinkageError: loader constraint violation: when resolving method ... previously initiated loading for a different type with name...

一般可以通過添加包含到@PowerMockIgnore一個方法類或包來解決。

在你的情況，我建議你嘗試添加測試 @PowerMockIgnore("org.omg.CORBA.ORB")
