描述：

我正在尝试测试来自类的静态方法。我使用powerMock (1.6.2) + mockito (1.10.19)以及Junit4 (4.12) & java8进行模拟。

问题：

获取错误：“无法转换名称为com.gs.ops.domain.StaticClass的类，原因: java.io.IOException:无效常量类型: 18”

尝试的解决方案：

powermock提供的

  1. - mockito和java-8
  2. Excluded java assist以及powermock (1.5.4，1.6.2...)

不同版本的java assist

下面的是异常堆栈跟踪：

Powermock 1.6.3使用javassist3.15.2-GA，它不支持某些类型。使用3.18.2-GA的javassist对我来说很有效。您可能希望重写项目中的依赖项。

代码语言：javascript

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

您可能会面临另一个问题，解决方案就在这里Mockito + PowerMock LinkageError while mocking system class

希望这能有所帮助。

因此，在3.18.2之前，javassist (字节码工具包)似乎存在问题，因为有一个已解决的JIRA ticket-223。

Javassist1 -在你的pom.xml中找到版本，可以使用mvn dependency任务

代码语言：javascript
复制
$ mvn dependency:tree | grep javassist
[INFO] |     \- org.javassist:javassist:jar:3.14.0-GA:compile

它由powermock-module-junit4-rule使用，

代码语言：javascript
复制
[INFO] +- org.powermock:powermock-module-junit4-rule:jar:1.4.9:test
[INFO] |  +- org.powermock:powermock-classloading-base:jar:1.4.9:test
[INFO] |  \- org.powermock:powermock-core:jar:1.4.9:compile
[INFO] |     \- org.javassist:javassist:jar:3.14.0-GA:compile

2 -所以，通过显式地将javassist版本更新到任何版本的>= 3.18.2应该可以工作。

在我的例子中，我使用的是use 3.20.0-GA

代码语言：javascript
复制
    <dependency>
        <groupId>org.javassist</groupId>
        <artifactId>javassist</artifactId>
        <version>3.20.0-GA</version>
    </dependency>

工作。使用scalatest

代码语言：javascript
复制
@PowerMockIgnore(Array("javax.management.*"))
@RunWith(classOf[PowerMockRunner])
@PrepareForTest(Array(classOf[Configurator]))
class LogServiceSpec {

  @Test
  def initialises_log4j2_on_each_instance_call() {
    PowerMockito.mockStatic(classOf[Configurator])

    val logService1 = new LogService
    PowerMockito.verifyStatic(Mockito.times(1))
    Configurator.initialize(Matchers.anyString(), Matchers.eq("log4j.config"))
  }
}

这是由于依赖关系的冲突造成的。解决依赖冲突是解决此问题的一种方法，另一种方法是重新排序pom.xml中的<dependency></dependency>元素。将powermock依赖项声明移到<dependencies></dependencies>部分的顶部。这是一个完全的黑客攻击，解决它的正确方法应该是解决依赖冲突。

要识别这些冲突，可以使用命令"mvn dependency:tree“。下面是我的应用程序的依赖关系树，我在其中遇到了同样的问题。请注意，在树中有两个对"javassist“的依赖关系。
