如何使用easymock-powermock模拟静态方法链调用？

import org.easymock.EasyMock;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(A.class) // 需要mock的类
public class MyTest {

    @Test
    public void testStaticMethodChain() {
        // 创建mock对象
        A mockA = EasyMock.createMock(A.class);
        B mockB = EasyMock.createMock(B.class);
        Result mockResult = EasyMock.createMock(Result.class);

        // mock静态方法链调用
        PowerMock.mockStatic(A.class);
        EasyMock.expect(A.method1()).andReturn(mockA);
        EasyMock.expect(mockA.method2()).andReturn(mockB);
        EasyMock.expect(mockB.method3()).andReturn(mockResult);
        PowerMock.replay(A.class, mockA, mockB);

        // 执行测试代码，验证结果
        // ...

        // 验证mock的方法是否被调用
        PowerMock.verifyAll();
    }
}
