java-8 - 使用 Java 8 的 Powermockito

Question

我正在使用 powermockito 在 Java 7 中模拟带有参数的静态方法。最近开始迁移到 Java 8。迁移后，powermockito 停止模拟静态方法并开始调用原始方法。

Pom.xml

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-api-mockito</artifactId>
    <version>1.6.5</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4-rule-agent</artifactId>
    <version>1.6.5</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.18.2-GA</version>
    <scope>test</scope>        
</dependency>

Test class
using spring runner with PowerMockRule
@RunWith(SpringJUnit4ClassRunner.class)

@Rule
public PowerMockRule rule = new PowerMockRule(); 

Below is the code used for mock/stubbing the static..

PowerMockito.stub(PowerMockito.method(ABCHelper.class, "prepareResult",Arg1.class,Arg2.class,Arg3.class,Arg4.class)).toReturn(mockedReturnedObject);

有人可以帮我解决这个问题吗？

下面的代码对我有用。请在新项目中尝试使用以下依赖项和代码。
