Question

我有类路径问题。

背景：构建并运行Spring WebApp。
原来是一个大项目，包括dao / service / controller / webapp。
我有将我的项目分解为maven模块项目，实质上是分裂来自dao和服务层的webapp。
现在我的webapp junit测试了别跑。
junit代码没有改变，我不认为依赖关系已经改变（虽然转移了）。
Spring-test正在进行中我的本地存储库。
Spring-test在我的单元测试运行时类路径中（使用mvn debug logging来检查）
我没有其他类路径问题。所有dao模块测试都运行良好

然而，我得到了

java.lang.NoClassDefFoundError: Could not initialize class
org.springframework.test.context.junit4.SpringJUnit4ClassRunner.

我将发布我的父母和子女pom.xml。如果有人有任何建议，我将非常感激。

Answer 1

我不知道为什么但是在我的情况下，spring-boot-starter-test附带了junit 4.10并且我发现它是用4.12编译的，所以添加后

 <dependency> 
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version> 
</dependency>

工作正常。也许在spring-boot的pom中配置错误

Answer 2

在评论中你说过项目编译，但测试没有运行。 Maven-surefire-plugin可能是罪魁祸首（就像我的情况一样）。我得到了同样的错误，但经过一番挖掘，我知道：

java.lang.NoClassDefFoundError: Could not initialize class
org.springframework.test.context.junit4.SpringJUnit4ClassRunner.

是由：

引起的

java.lang.IllegalStateException: SpringJUnit4ClassRunner requires JUnit 4.12 or higher.
    at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<clinit>

因为maven-surefire-plugin没有从类路径中选择测试框架提供程序而是提供了自己过时的junit提供程序而引发了

。

通过指定JUnit工件名称来消除错误：

<plugins>
...
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>{your.surefire.version}</version>
        <configuration>
            <junitArtifactName> junit:junit:{your.junit.version} </junitArtifactName>
        </configuration>
    </plugin>
...
</plugins>

Answer 3

对于任何看到这个问题的人来说，我遇到了类似的问题，而这个问题与在spring boot中从maven传递依赖项中引入的日志记录impl冲突有关。一旦我排除了spring-boot-starter-logging，就解决了这个问题。

SpringJUnit4ClassRunner很可能无法在日志记录冲突中初始化类加载器，因此在代码中的另一个点抛出NoClassDefFoundError。

Answer 4

我找到了一个解决方案，而不是我的问题的答案。

解决方案是分阶段破坏项目。

首先，我创建了三个独立项目，并对每个项目进行了相关的单元测试。（显然必须以正确的顺序完成，以确保依赖）
其次，我创建了父pom和依赖关系管理。
第三，我将每个独立项目一个接一个地带到了paren之下。我通过迭代的一系列测试逐渐减少了孩子的pom依赖。

我仍然不知道为什么上述结构失败了。但是，由于现在一切正常，因此在我最终再次破坏我的webapp之前没有理由继续减少。

Answer 5

我最近遇到过这个。我刚刚将版本从3.0.7.RELEASE更新为3.1.1.RELEASE。

Answer 6

我在Spring Boot中遇到了同样的错误。我刚刚将spring-boot-starter-parent版本从1.5.6.RELEASE更改为1.5.10.RELEASED。

这个春季启动版已经包含以下类：

org.springframework.test.context.junit4.SpringJUnit4ClassRunner

Answer 7

我使用了 springmockk 依赖，这导致了这些错误。我使用旧版本修复了它，因为最新版本与我的旧 Springboot 版本不兼容。

Maven：NoClassDefFoundError：org.springframework.test.context.junit4.SpringJUnit4ClassRunner
