Error AnnotatedElementUtils spring

Question

I wrote a jUnit test, but I have an error while executing it:

java.lang.NoClassDefFoundError: org/springframework/core/annotation/AnnotatedElementUtils at org.springframework.test.context.MetaAnnotationUtils$AnnotationDescriptor.<init>(MetaAnnotationUtils.java:269) at org.springframework.test.context.MetaAnnotationUtils$AnnotationDescriptor.<init>(MetaAnnotationUtils.java:257) at org.springframework.test.context.MetaAnnotationUtils$UntypedAnnotationDescriptor.<init>(MetaAnnotationUtils.java:326) at org.springframework.test.context.MetaAnnotationUtils.findAnnotationDescriptorForTypes(MetaAnnotationUtils.java:171) at org.springframework.test.context.ContextLoaderUtils.buildMergedContextConfiguration(ContextLoaderUtils.java:621) at org.springframework.test.context.DefaultTestContext.<init>(DefaultTestContext.java:93) at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:119) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTestContextManager(SpringJUnit4ClassRunner.java:120) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.<init>(SpringJUnit4ClassRunner.java:109) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:526) at org.junit.internal.builders.AnnotatedBuilder.buildRunner(AnnotatedBuilder.java:31) at org.junit.internal.builders.AnnotatedBuilder.runnerForClass(AnnotatedBuilder.java:24) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.builders.AllDefaultPossibilitiesBuilder.runnerForClass(AllDefaultPossibilitiesBuilder.java:29) at org.junit.runners.model.RunnerBuilder.safeRunnerForClass(RunnerBuilder.java:57) at org.junit.internal.requests.ClassRequest.getRunner(ClassRequest.java:24) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.<init>(JUnit4TestReference.java:33) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestClassReference.<init>(JUnit4TestClassReference.java:25) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:48) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:452) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.lang.ClassNotFoundException: org.springframework.core.annotation.AnnotatedElementUtils at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 27 more 

My application is configured this way:

My test:

 @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("TestDao-context.xml") public class TestDao { @Autowired private Dao test; @Test public void test() { Dao test = new DaoImpl(); try { test.connect(); assertTrue(true); } catch (UnknownHostException e) { e.printStackTrace(); assertTrue(false); } } } 

my context config:

  <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- Uncomment and add your base-package here: <context:component-scan base-package="org.springframework.samples.service"/> --> <!-- DAO --> <!-- MongoFactoryBean instance --> <bean id="mongoFactoryBean" class="org.springframework.data.mongodb.core.MongoFactoryBean"> <property name="host" value="127.0.0.1" /> <property name="port" value="27017"/> </bean> <bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory"> <constructor-arg name="mongo" ref="mongoFactoryBean" /> <constructor-arg name="databaseName" value="agence_voyage" /> </bean> <bean id="dao" class="dao.daoImpl.DaoImpl"> <property name="mongoFactory" ref="mongoDbFactory" /> </bean> <!-- Services --> <bean id="service" class="service.serviceImpl.ServiceImpl"> <property name="dao" ref="dao"/> </bean> <!-- Tests --> <bean id="testDao" class="testdao.TestDao"> <property name="test" ref="dao"/> </bean> </beans> 

my web.xml config:

  <?xml version="1.0" encoding="ISO-8859-1"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>AgenceVoyage</display-name> <!-- - Location of the XML file that defines the root application context. - Applied by ContextLoaderListener. --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/application-config.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- - Servlet that dispatches request to registered handlers (Controller implementations). --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/mvc-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> 

The configuration seems to be good according to various tutorials on the Internet, but I don't know where this error came from.

I think TestDao-context.xml is not very well implemented by my test class, because when I move the context file to another project, the error does not change at all. In addition, I checked many different ways to configure my @ContextConfiguration and didn't change anything.

Do you see something wrong?

Answer 1

The actual problem is the inconsistency between spring-test and other versions of spring - * jar (possibly 3.xx and 4.xx are not compatible with others). Anyone who could not run into this problem can use the same spring for all spring dependencies.

Answer 2

To solve this problem, all I did was update my pom configuration: I updated the version of spring -test (4.0.0.RELEASE) and JUnit.
