SpringFramework JUnit MergedAnnotations java.lang.NoClassDefFoundError

问题

尝试在Java SpringBoot应用程序中运行一些单元测试。

我运行的单元测试代码如下:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;
import static org.junit.Assert.assertEquals;

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {WebAppInitializer.class})
public class FilePropertyInjectionUnitTest {
   @Value("${geckoDir}")
   private String geckoDir;

   @Test
   public void whenFilePropertyProvided_thenProperlyInjected() {
      assertEquals(geckoDir, "C:\\GeckoDriver\\geckodriver.exe");
   }
}

我遇到了以下错误:

java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations
    at org.springframework.test.context.support.DynamicPropertiesContextCustomizerFactory.isAnnotated(DynamicPropertiesContextCustomizerFactory.java:53)
    at org.springframework.core.MethodIntrospector.lambda$selectMethods$1(MethodIntrospector.java:97)
    at org.springframework.core.MethodIntrospector.lambda$selectMethods$0(MethodIntrospector.java:74)
    at org.springframework.util.ReflectionUtils.doWithMethods(ReflectionUtils.java:410)
    at org.springframework.core.MethodIntrospector.selectMethods(MethodIntrospector.java:72)
    at org.springframework.core.MethodIntrospector.selectMethods(MethodIntrospector.java:96)

我使用的是IntelliJ作为IDE。

英文:

Try ro run some unit tests in a Java SpringBoot application.

The unit test I run is :

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Value;

import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;

import static org.junit.Assert.assertEquals;

@RunWith(SpringRunner.class)
@ContextConfiguration(classes = {WebAppInitializer.class})
public class FilePropertyInjectionUnitTest {
   @Value("${geckoDir}")
   private String geckoDir;

   @Test
   public void whenFilePropertyProvided_thenProperlyInjected() {
      assertEquals(geckoDir,"C:\\GeckoDriver\\geckodriver.exe");
   }
}

And I got the following error:

java.lang.NoClassDefFoundError: org/springframework/core/annotation/MergedAnnotations

at org.springframework.test.context.support.DynamicPropertiesContextCustomizerFactory.isAnnotated(DynamicPropertiesContextCustomizerFactory.java:53)
at org.springframework.core.MethodIntrospector.lambda$selectMethods$1(MethodIntrospector.java:97)
at org.springframework.core.MethodIntrospector.lambda$selectMethods$0(MethodIntrospector.java:74)
at org.springframework.util.ReflectionUtils.doWithMethods(ReflectionUtils.java:410)
at org.springframework.core.MethodIntrospector.selectMethods(MethodIntrospector.java:72)
at org.springframework.core.MethodIntrospector.selectMethods(MethodIntrospector.java:96)

I am using ItelliJ as IDE .

我终于弄清楚了这个问题。我不得不将spring-test依赖项升级到版本5.2.8:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.2.8.RELEASE</version>
    <scope>test</scope>
</dependency>

我真的在这个问题上走了很深。

英文:

I finally figure this one out.I had to upgrade spring-test dependency to version 5.2.8:

    &lt;dependency&gt;
        &lt;groupId&gt;org.springframework&lt;/groupId&gt;
        &lt;artifactId&gt;spring-test&lt;/artifactId&gt;
        &lt;version&gt;5.2.8.RELEASE&lt;/version&gt;
        &lt;scope&gt;test&lt;/scope&gt;
    &lt;/dependency&gt;

I really went down the rabitt hole with this one

以下是我的POM的一部分。我不知道哪些JAR包发生了冲突。

Below is part of my POM. I don't know what jars are clashing.
