CGLIB 普通用法-白红宇

定义拦截回调，实现MethodInterceptor接口

package proxy;import net.sf.cglib.proxy.MethodInterceptor;import net.sf.cglib.proxy.MethodProxy;import java.lang.reflect.Method;/** * @author Mr Morning * @date 2019/4/30 08:54 */public class CglibProxy implements MethodInterceptor {    @Override    public Object intercept(Object obj, Method method, Object[] args, MethodProxy methodProxy) throws Throwable {        System.out.println("before invoke");        methodProxy.invokeSuper(obj, args);        System.out.println("after invoke");        return obj;    }}复制代码

定义被代理对象

package proxy;/** * @author Mr Morning * @date 2019/4/30 08:56 */public class Run {    public void run(){        System.out.println("runing......");    }}复制代码

测试

@Test    public void testCglib(){        Enhancer enhancer = new Enhancer();        // 设置被代理类        enhancer.setSuperclass(Run.class);        // 设置拦截回调        enhancer.setCallback(new CglibProxy());        // 创建代理类        Run o = (Run) enhancer.create();        // 判断是否为代理类        boolean is = o.getClass().getName().contains("$$EnhancerByCGLIB$$");        System.out.println(is);        o.run();        System.out.println("end");    }复制代码
