拦截器

package com.example.interceptor;import org.aopalliance.intercept.MethodInterceptor;import org.aopalliance.intercept.MethodInvocation;/** * @Author: sun * @Email: szw3366@126.com * @Date: 2017/12/5 * @Time: 13:17 * @Description: ${DESCRIPTION} */public class MyMethodInterceptor implements MethodInterceptor{    @Override    public Object invoke(MethodInvocation methodInvocation) throws Throwable {        System.out.println("调用方法前调用");        Object o = methodInvocation.proceed();        System.out.println("调用方法后调用");        return o;    }}

注册器

package com.example.interceptor;import org.aopalliance.aop.Advice;import org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;/** * @Author: sun * @Email: szw3366@126.com * @Date: 2017/12/5 * @Time: 13:20 * @Description: ${DESCRIPTION} */@Configurationpublic class AppConfig {    /**     *  加载前注册     * @return     */    @Bean    public Advice myMethodInterceptor(){        return new MyMethodInterceptor();    }    @Bean    public BeanNameAutoProxyCreator beanNameAutoProxyCreator() {        BeanNameAutoProxyCreator beanNameAutoProxyCreator = new BeanNameAutoProxyCreator();        beanNameAutoProxyCreator.setBeanNames("*userInfoService*");        beanNameAutoProxyCreator.setInterceptorNames("myMethodInterceptor");        return beanNameAutoProxyCreator;    }}
