JUnit test appears java.lang.IllegalStateException:Failed to load ApplicationContext

The course design requires the JUnit test, which I tested on the already well-done SSH project, and the test class code is as follows

Package Com.zhang.web.services;importStaticorg.junit.assert.*; import org.junit.after;import org.junit.before;import org.junit.test;import javax.annotation.Resource;  Import Org.junit.runner.RunWith; Import Org.springframework.test.context.junit4.abstractjunit4springcontexttests;import  Org.springframework.test.context.ContextConfiguration;  Import Org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith (Springjunit4classrunner.class) @ContextConfiguration (Locations="Classpath:spring-beans.xml")   Public classUserdaotest extends abstractjunit4springcontexttests{@Resource (name="Userdao") PrivateUserdao Userdao; Public voidSetuserdao (Userdao Userdao) { This. Userdao =Userdao;} @Before Public voidsetUp () throws Exception {} @After Public voidTearDown () throws Exception {} @Test Public voidTestfinduser () {assertequals (Userdao.finduser (0),NULL);}}

The following error occurred while running the test

The workaround is to copy the Spring-beans.xml configuration file to the SRC directory.

Problem reason: I always think Eclipse's classpath includes Web-inf directory, not actually. We can open the. classpath file under the Web project with the following contents

<?xml version="1.0"encoding="UTF-8"? ><classpath><classpathentry kind="src"Path="src"/><classpathentry kind="Con"Path="Org.eclipse.jdt.launching.jre_container/org.eclipse.jdt.internal.debug.ui.launcher.standardvmtype/jre7 "><attributes><attribute name="owner.project.facets"Value="Java"/></attributes></classpathentry><classpathentry kind="Con"Path="Org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimetarget/apache Tomcat v7.0"><attributes><attribute name="owner.project.facets"Value="Jst.web"/></attributes></classpathentry><classpathentry kind="Con"Path="Org.eclipse.jst.j2ee.internal.module.container"/><classpathentry kind="Con"Path="Org.eclipse.jdt.user_library/spring3"/><classpathentry kind="Con"Path="org.eclipse.jdt.user_library/struts"/><classpathentry kind="Con"Path="org.eclipse.jdt.user_library/hibernate"/><classpathentry kind="Con"Path="ORG.ECLIPSE.JDT.JUNIT.JUNIT_CONTAINER/4"/><classpathentry kind="Output"Path="build/classes"/></classpath>

In this, we do not see that the classpath contains the Web-inf directory. If we add <classpathentry kind= "src" path= "Webcontent/web-inf"/> and then restart Eclipse, you will notice that the above problem does not exist and the test class runs successfully.
