java - PowerMockito 和 CORBA 冲突

Question

我正在尝试使用 PowerMockito 对使用使用 CORBA 的第三方库的项目进行一些测试。我试图通过找到问题的根源来跳过这个异常。我没有成功找到有关此事的信息。

这是我无法使其工作的最简单的代码:

Java 类

@RunWith(PowerMockRunner.class)
public class ORBTest {

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

pom.xml

如果有人能在这里给我一些启发，我将不胜感激，因为您不知道要更改什么才能使这项工作成功。

Answer 1

像这样的错误

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

通常可以通过将包含方法的类或包添加到 @PowerMockIgnore 来解决。

在你的情况下，我建议尝试添加到测试 @PowerMockIgnore("org.omg.CORBA.ORB")
