Java Project: Failed to load ApplicationContext

Question

I have a Java Project in which I am writing a simple JUNIT test case. I have copied the applicatinoContext.xml file into the root java source directory. I've tried it with some of the recommended settings I have read of here on StackOverflow but still get the same error. Is this error happening due to my project being a java project and NOT a web project, or does that even matter? I'm not sure where im going wrong.

import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.transaction.annotation.Transactional;  @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"C:/projs/sortation/src/main/java/applicationContext.xml"}) // Also tried these settings but they also didnt work, //@ContextConfiguration(locations={"classpath:applicationContext.xml"}) //@ContextConfiguration("classpath:applicationContext.xml") @Transactional public class TestSS {      @Autowired     private EmsDao dao;      @Test     public void getSites() {          List<String> batchid = dao.getList();          for (String s : batchid) {             System.out.println(s);         }     } } 

Answer 1

Looks like you are using maven (src/main/java). In this case put the applicationContext.xml file in the src/main/resources directory. It will be copied in the classpath directory and you should be able to access it with

@ContextConfiguration("/applicationContext.xml") 

From the Spring-Documentation: A plain path, for example "context.xml", will be treated as a classpath resource from the same package in which the test class is defined. A path starting with a slash is treated as a fully qualified classpath location, for example "/org/example/config.xml".

So it's important that you add the slash when referencing the file in the root directory of the classpath.

If you work with the absolute file path you have to use 'file:C:...' (if I understand the documentation correctly).

I had the same problem, and I was using the following plugin for tests:

<plugin>     <groupId>org.apache.maven.plugins</groupId>     <artifactId>maven-surefire-plugin</artifactId>     <version>2.9</version>     <configuration>         <useFile>true</useFile>         <includes>             <include>**/*Tests.java</include>             <include>**/*Test.java</include>         </includes>         <excludes>             <exclude>**/Abstract*.java</exclude>         </excludes>         <junitArtifactName>junit:junit</junitArtifactName>         <parallel>methods</parallel>         <threadCount>10</threadCount>     </configuration> </plugin> 

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>     <threadCount>10</threadCount> 

Hope that this helps someone out!
