Could not instantiate bean class[org.springframework.aop.aspectj.AspectJPointcutAdv i

[mone855]

Hi I am Manjunath I am facing a issue while passing a userdefined argument through spring aop.

this is my context 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"

	</property>
	<property name="id">

	</bean>

	<bean id="Demographics" class="example.CaptureDemogrphicsImpl"/>
	
	<aop:config>
		<aop:aspect id="EncryptionAspect" ref="EncryptionHandler">
			<aop:around
			      method="encryption" 
			      pointcut="execution(* example.CaptureDemogrphics.submitDemoInfo(Userdetails)) and args(userdetails)"/>
		</aop:aspect>
		
		<!--<aop:aspect id="AuditAspect" ref="AuditHandler">

			      pointcut="execution(* example.CaptureDemogrphics.submitDemoInfo(String,String))"/>
		</aop:aspect>
	--></aop:config>

</beans>

my advice class is

package example;

import example.UserDetails;



public class EncryptionHandler {
	


	EncryptionHandler(){
		
		System.out.println("I am in the EncryptionHandler constructor");
	}

	public String encryption(UserDetails userdetails) {
		   String username =  userdetails.getUserName();
		   String id = (String) userdetails.getId();
		   System.out.println("Demographics Data   userName= "+ username +"		"+ "pass= " + id);
		return "data is encrypted hash map";
	   }


}

target interface

package example;

import example.UserDetails;

public interface CaptureDemogrphics {
	
	public String submitDemoInfo(UserDetails userdetails);
}

target implementation class

package example;

public class CaptureDemogrphicsImpl implements CaptureDemogrphics {

	public String submitDemoInfo(UserDetails userdetails) {
	
		return "return userdetails bean";
	}
	
	
}

this is my calling class

package example;

import example.UserDetails;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class CaptureDemoUI {

	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext(
				"example/aopContext.xml");
		CaptureDemogrphics CaptureDemogrphicsService = (CaptureDemogrphics) context
				.getBean("Demographics");
		UserDetails userDetails = (UserDetails) context
		.getBean("userDetails");
		userDetails.setUserName("monem");
		userDetails.setId("210080");

		String returnval = CaptureDemogrphicsService
				.submitDemoInfo(userDetails);

		
		System.out.println("returnvalue :- " + returnval);

	}

}

I am getting this error while calling submitDemoInfo(userDetails) with around advice

please give solution for this (it is urgent for my project)

thanks,

Your encryption class is wrong, if you read the documentation for the around advice.

The first parameter of the advice method must be of type ProceedingJoinPoint. Within the body of the advice, calling proceed() on the ProceedingJoinPoint causes the underlying method to execute. The proceed method may also be called passing in an Object[] - the values in the array will be used as the arguments to the method execution when it proceeds.

So change your method signature.

hi,

do u mean, i need to change my aopcontext.xml file.
If we pass String param in the execution of aopcontext.xml file , it works fine but when we pass an object instance it gives error

[Marten Deinum]

Read the documentation regarding around advices!

public class EncryptionHandler {

  EncryptionHandler(){		
    System.out.println("I am in the EncryptionHandler constructor");
  }

  public String encryption(ProceedingJoinPoint pjp, UserDetails userdetails) {
    String username =  userdetails.getUserName();
    String id = (String) userdetails.getId();
    System.out.println("Demographics Data   userName= "+ username +"		"+ "pass= " + id);
    return "data is encrypted hash map";
  }
}

[Marten Deinum]

Next to that specify the fully qualified classname for UserDetails in your pointcut...

<aop:config>
		<aop:aspect id="EncryptionAspect" ref="EncryptionHandler">
			<aop:around
          method="encryption" 
			    pointcut="execution(* example.CaptureDemogrphics.submitDemoInfo(example.Userdetails)) and args(userdetails)"/>
		</aop:aspect>		
</aop:config>

Which is given away by your exception.

Caused by: java.lang.IllegalArgumentException: warning no match for this type name: Userdetails [Xlint:invalidAbsoluteTypeName]

Now it working properly

Thank u Marten,
