我想使用PowerMock模拟以下代码：
ConnectionFactory rabbitMqFactory = createFactory();
com.rabbitmq.client.Connection connection = rabbitMqFactory.newConnection();
com.rabbitmq.client.Channel channel = con.createChannel();
com.rabbitmq.client.QueueingConsumer consumer = new com.rabbitmq.client.QueueingConsumer(channel);
然而，当我嘲笑QueueingConsumer时
@RunWith(PowerMockRunner.class)
@PrepareForTest({MyClass.class})
public class MyClassTester {
@Test
public void test() {
QueueingConsumer consumer = createMock(QueueingConsumer.class);
MyClass myClass = new MyClass();
// other code mock here ...
PowerMock.expectNew(QueueingConsumer.class, Channel.class).andReturn(consumer);
replayAll();
myClass.callRabbitMq();
verifyAll();
}
}
我总是得到以下例外：
org.powermock.reflect.exceptions.FieldNotFoundException: No instance field of type "org.easymock.internal.MocksControl$MockType" could be found in the class hierarchy of org.easymock.internal.MocksControl.

我只是不明白为什么。我的代码有问题吗？我已经用不同的方法重写了它，但在使用expectNew时总会出现这个错误。或者这是PowerMock 1.5.1版本的当前问题？
-谢谢-
您使用的是Easymock的哪个版本？当我有3.2版本的EasyMock时，我也遇到了同样的问题，但使用3.1还可以。我相信Powermock 1.5.1预计无论如何都会提供EasyMock3.1，所以这将是正确的使用版本。
我在使用以下jar时遇到了同样的错误：

我通过将easymock-3.2.jar替换为easymok-3.1.jar修复了这个错误。可以在官方下载网站上找到：http://easymock.org/Downloads.html
