jar包

<!-- https://mvnrepository.com/artifact/cglib/cglib -->
<dependency>
  <groupId>cglib</groupId>
  <artifactId>cglib</artifactId>
  <version>3.1</version>
</dependency>

代码：

　　切面：

package com.blb.proxy;

public class AOPS{
    public void sayhello()
    {
        System.out.println("我是AOPS类中的sayhello方法");
    }

    public void before()
    {
        System.out.println("我是前面");
    }

    public void after()
    {
        System.out.println("我是后面");
    }

}

　　关注点：

package com.blb.proxy;

public class Hello {
    public void sayhello()
    {
        System.out.println("我是Hello类中的sayhello方法");
    }
}

　　切入规则：

package com.blb.proxy;

import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

import java.lang.reflect.Method;

public class Rule implements MethodInterceptor {
    private AOPS aops = new AOPS();

    @Override
    public Object intercept(Object o, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {
        aops.before();
        Object result = methodProxy.invokeSuper(o,objects);
        aops.after();
        return result;
    }
}

　　开始切入：

package com.blb.proxy;

import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

import java.lang.reflect.Method;

public class Rule implements MethodInterceptor {
    private AOPS aops = new AOPS();

    @Override
    public Object intercept(Object o, Method method, Object[] objects, MethodProxy methodProxy) throws Throwable {
        aops.before();
        Object result = methodProxy.invokeSuper(o,objects);
        aops.after();
        return result;
    }
}
