java - NoSuchMethodError : javassist. CtClass.getDeclaredClasses()-6ren

java - NoSuchMethodError : javassist. CtClass.getDeclaredClasses()

转载作者：行者123 更新时间：2023-12-02 09:15:40

我已经为这个错误苦苦挣扎了两天。我在一个 spring、maven 项目中，使用 Intellij。

我已经尝试了在这里找到的每一个问题，但什么也没有。我尝试过很多版本，但什么也没有。

我完全被以下异常所困扰:

java.lang.NoSuchMethodError: javassist.CtClass.getDeclaredClasses()[Ljavassist/CtClass;

这是我的代码:

测试

package com.secondrain.utils;

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

@RunWith(PowerMockRunner.class)
@PrepareForTest(CompanyManager.class)
public class CompanyTest {

  @Test
  public void test() {}

}

如果我删除 PowerMock，一切都会正常工作:

package com.secondrain.utils;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;

@RunWith(BlockJUnit4ClassRunner.class)
public class CompanyTest {

  @Test
  public void test() {}

}

最佳答案

首先，这个:

javassist.CtClass.getDeclaredClasses()[Ljavassist/CtClass;

返回 javassist.CtClass 中具有签名的方法

<modifier> javassist.CtClass getDeclaredClasses()

根据published javadocs javassist 3.15 版本中添加了“缺失”方法。

因此，直接的解释是 JVM 在运行时类路径上找到的 javassist 的第一个 JAR 文件是旧版本的。

Maven依赖树显示PowerMock 2.0.2依赖

 org.javassist:javassist:jar:3.24.0-GA

但显然，当您运行测试时，运行时类路径上存在另一个版本的 JAR。神秘!

然后您说具有相同依赖项的干净项目不会出现此问题。至少这是有道理的。 (对我来说。)

<小时/>

如何解决这个问题？

您的计算机上必须有旧版(3.15 之前)javassist JAR 文件的一个或多个副本。找到它或他们。例如，在 Linux 上查找 $HOME -name javassist\* -type f，然后查看路径名。

接下来，尝试找出运行测试时正在使用的类路径。

如果您使用 maven 命令运行它们，-X(调试)选项将向您显示许多额外信息。根据Find classpath maven is using for running testng testcase ，这包括实际的类路径。
如果您在 IDE 中使用测试运行程序，请检查 IDE 文档。

最后，分析类路径以查找路径上为何存在旧的 javassist JAR。

FWIW，我的猜测是您正在 IDE 中运行测试，并且 IDE 以某种方式添加了虚假 JAR。这可能是 IDE 未正确清除的旧(或升级)依赖项的传递依赖项。
