In this example you will see the use of DefaultAdvisorAutoproxyCreator. It automatically creates the prxy for every bean of an application. There is no need to create the proxy bean manually if you are using DefaultAdvisorAutoproxyCreator.

EmployeBean.java

package roseindia.net.bean;

public class EmployeBean {
	String empName;
	int empId;

	public EmployeBean() {

	}

	public String getEmpName() {
		return empName;
	}

	public void setEmpName(String empName) {
		this.empName = empName;
	}

	public int getEmpId() {
		return empId;
	}

	public void setEmpId(int empId) {
		this.empId = empId;
	}

	public EmployeBean(String empName, int empId) {
		this.empName = empName;
		this.empId = empId;
	}

	public void showDetail() {
		System.out.println("Name " + this.empName + " Id " + this.empId);
	}
}

MethodBeforeAdviceExample.java

package roseindia.net.advice;

import java.lang.reflect.Method;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;
import org.springframework.aop.MethodBeforeAdvice;

public class MethodBeforeAdviceExample implements MethodBeforeAdvice {

	@Override
	public void before(Method method, Object[] objects, Object object)
			throws Throwable {
		// TODO Auto-generated method stub
		System.out.println("Inside Method Before Advice");
		System.out.println("Executing " + method.getName() + "() Method");
	}

}

MainClaz.java

package roseindia.net.main;

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

import roseindia.net.bean.EmployeBean;

public class MainClaz {
	public static void main(String args[]) {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
				new String[] { "roseindia/net/config/springConfig.xml" });
		EmployeBean employeBean = (EmployeBean) applicationContext
				.getBean("employeBean");
		employeBean.showDetail();

	}
}

springConfig.xml

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

  <bean id="employeBean" class="roseindia.net.bean.EmployeBean">
    <property name="empName" value="Vinay" />
    <property name="empId" value="007" />
  </bean>

  <bean id="beforeAdvice" class="roseindia.net.advice.MethodBeforeAdviceExample" />

  <bean id="employeAdvisor"
    class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor">
    <property name="mappedName" value="showDetail" />
    <property name="advice" ref="beforeAdvice" />
  </bean>
  <bean
    class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" />
