重新生产的步骤，
使用受保护的方法创建一个类，并在子类中重写相同的方法。
为子类创建一个测试，并尝试抑制方法调用 throws TooManyMethodsFoundException .
测试接口.java

package com.test.powermock;

/**
 * Created by dineshkumar on 06/05/16.
 */
public interface TestInterface {
    public int testMethod() throws Exception;
}

抽象测试.java

package com.test.powermock;

/**
 * Created by dineshkumar on 06/05/16.
 */
public abstract class AbstractTest implements TestInterface {

public int testMethod() throws Exception {
        return 0;
    }

    protected void voidMethodWithParams(String a) throws Exception{

    }
}

implclasstest.java文件

package com.test.powermock;

/**
 * Created by dineshkumar on 06/05/16.
 */
public class ImplClassTest extends AbstractTest {

    @Override
    public int testMethod() throws Exception {
        voidMethodWithParams("a");
        return 2;
    }

    @Override
    protected void voidMethodWithParams(String a) throws Exception{
        System.out.println("dd");
    }
}

implclasstesttest.java文件

package com.test.powermock;

import org.powermock.api.mockito.PowerMockito;
import static org.powermock.api.support.membermodification.MemberMatcher.method;
import static org.powermock.api.support.membermodification.MemberModifier.suppress;
import static org.testng.Assert.*;

/**
 * Created by dineshkumar on 06/05/16.
 */
public class ImplClassTestTest {

    @org.testng.annotations.Test
    public void testTestMethod() throws Exception {
        ImplClassTest implClassTestSpy = PowerMockito.spy(new ImplClassTest());
        suppress(method(ImplClassTest.class, "voidMethodWithParams", String.class));
        int res = implClassTestSpy.testMethod();
        assertEquals(res, 2);
    }
}

在谷歌之后，https://groups.google.com/forum/#!主题/powermock/h1u5yyexqfy
还尝试了以下代码，

package com.test.powermock;

import org.powermock.api.mockito.PowerMockito;

import static org.powermock.api.support.membermodification.MemberMatcher.method;
import static org.powermock.api.support.membermodification.MemberModifier.suppress;
import static org.testng.Assert.*;

/**
 * Created by dineshkumar on 06/05/16.
 */
public class ImplClassTestTest {

    @org.testng.annotations.Test
    public void testTestMethod() throws Exception {
        ImplClassTest implClassTestSpy = PowerMockito.spy(new ImplClassTest());
        suppress(method(AbstractTest.class, "voidMethodWithParams", String.class));
        suppress(method(ImplClassTest.class, "voidMethodWithParams", String.class));
        int res = implClassTestSpy.testMethod();
        assertEquals(res, 2);
    }
}

有什么方法可以抑制这些方法吗？

重新描述问题：
使用powermock suppress + method() 无法正确获取 @Overriden protected 方法：voidmethodwithparams，因为问题 TooManyMethodsFoundException ，找到类中存在的两个方法 ImplClassTest 以及 AbstractTest 问题：找到两种方法！powermock不知道该抑制哪一个。

// encounter TooManyMethodsFoundException !!!
    suppress(method(AbstractTest.class, "voidMethodWithParams", String.class));

解决方法：这个问题肯定难看，用java原创的方式 foo.class.getMethod() （仅公开）或 bar.class.getDeClaredMethod() （受保护和私人）

// "voidMethodWithParams" is protected method use getDeclaredMethod()
 suppress(ImplClassTest.class.getDeclaredMethod("voidMethodWithParams", String.class))
// "publicMethod" use getMethod()
 suppress(ContainPublicMethodClass.class.getMethod("publicMethod", foo.class))

ps：如果您想在一个类中抑制所有方法，请使用powermock的 methodsDeclaredIn() ```
import static org.powermock.api.support.membermodification.MemberMatcher.methodsDeclaredIn;
suppress(methodsDeclaredIn(AbstractTest.class))
