com.thoughtworks.xstream.converters.ConversionException: 无法调用

Question

我遇到了使用 PowerMockito 测试 SpringCamelContext 单元测试的情况，我收到以下消息 error.Does 有人知道如何解决它。如果我申请

@Rule
    public PowerMockRule rule = new PowerMockRule();

以及以下依赖项。

<dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-module-junit4-rule</artifactId>
            <version>1.7.1</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.powermock</groupId>
            <artifactId>powermock-classloading-xstream</artifactId>
            <version>1.7.1</version>
            <scope>test</scope>
        </dependency>

然后只有我收到以下错误：

 com.thoughtworks.xstream.converters.ConversionException: Could not call java.security.CodeSource.readObject() : null

    version             : 1.4.7

有人知道怎么解决吗？？？？

Answer 1

为了解决这个问题。我将其替换为以下注释而不是 PowerMockRule。

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringJUnit4ClassRunner.class)

还从 Pom.xml 中删除了依赖项 powermock-module-junit4-rule & powermock-classloading-xstream 并且它有效。
