I am working on a simple spring project which has following code:
package com.luv2code.springdemo2;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class AnnotationDemoApp {
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Coach theCoach = context.getBean("tennisCoach", Coach.class);
System.out.println(theCoach.getDailyWorkout());
context.close();
}
}
ApplicationContext.xml:
<?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/context
http://www.springframework.org/schema/context/spring-context.xsd">
<context:annotation-config />
<context:component-scan base-package="com.luv2code.springdemo2"></context:component-scan>
</beans>
Coach.java
package com.luv2code.springdemo2;
public interface Coach {
public String getDailyWorkout();
}
TennisCoach.java:
package com.luv2code.springdemo2;
import org.springframework.stereotype.Component;
#Component("tennisCoach")
public class TennisCoach implements Coach {
#Override
public String getDailyWorkout() {
// TODO Auto-generated method stub
return "Practise your back hand volley daily";
}
}
I am not able to figure out why the error is occurring.
Error message:

I am using spring version 5 and I have added all the JAR files in the lib folder:
The applicationContext.xml file is present at the correct hierarchy, that is, there are no file location error
I am able to use XML based handling but not component annotations.
What is the problem here?
Kindly comment if other information is needed
You're missing spring-aop-5.3.9.jar. That's where the class that's reported missing (org.springframework.aop.TargetSource) is from, but you only have the sources and javadoc JAR files for spring-aop, not the JAR file with the actual classes.

Add the following to your pom.xml (if using maven)
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>4.2.1.RELEASE</version>
</dependency>
As you can see in the stacktrace the error is java.lang.ClassNotFoundException: org.springframework.aop.TargetSource.
That means, that you miss the spring-aop.jar in your classpath.
Add it as a dependecy to your pom.xml if you work with maven. If not you have to add it and all the dependencies manually to your classpath.
You could download required jar from Maven repo. and add the same in your classpath. I hope it will work fine.

You have a mismatch in java versions: version 57 is java 13
You probably need to mvn clean install again and check your versions.

I'm using NetBeans IDE. I also included the Spring Library and Components Logging.
Can someone help me and point out if I'm doing something wrong. Thank you.
You need to add the package. new ClassPathXmlApplicationContext("spring.xml"); should be new ClassPathXmlApplicationContext("org/spring/application/spring.xml");
You should place your spring.xml in the resource folder.

}
and its unit test:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration()
public class ApplicationContextProviderTest {
#Test
public void getApplicationContextInstance(){
assertNotNull(ApplicationContextProvider.getApplicationContext());
}
}
with the following resource file (same package with test class):
ApplicationContextProviderTest-context.xml

When I run the test, I get this error:

How can I fix this? I'm guessing that this is caused by wrong versioning of spring core
Any better way to test ApplicationContextProvider?
Thanks!
I found the same error while testing Spring Security 4.0.0.M1.
With 3.2.4.RELEASE there is no trouble.
Try it with 3.2.4.RELEASE.
It turned out I should use spring-test-3.0.5, like the version of my other spring jars.
I have seen this error message when dealing with Apache Tomcat and webapps.
A jar/class could be in the classpath when Apache Tomcat is being launched AND also be included within the webapp classes/lib folder.
The solution in this case is remove the duplicate class/jar.
