spring AOP 简单入门案例

TestServiceinter.java

package com.frank.aop;

public interface TestServiceinter {
    public void SayHello();

}

TestServiceImp.java

package com.frank.aop;

public class TestServiceImp implements TestServiceinter {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public void SayHello() {
        // TODO Auto-generated method stub
        System.out.println(name+"hello");

    }

}

MyMethodBeforeAdvice.java

package com.frank.aop;

import java.lang.reflect.Method;

import org.springframework.aop.MethodBeforeAdvice;

public class MyMethodBeforeAdvice implements MethodBeforeAdvice {

    @Override
    public void before(Method method, Object[] args, Object target)
            throws Throwable {
        // TODO Auto-generated method stub
        System.out.println("记录日志中。。。。"+method.getName());

    }

}

App1.java

package com.frank.aop;

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

public class App1 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ApplicationContext ac=new ClassPathXmlApplicationContext("com/frank/aop/beans.xml");
        TestServiceinter Ts=(TestServiceinter) ac.getBean("proxyFactoryBean");
        Ts.SayHello();

    }

}
