spring development using XML configuration Spring AOP

 　　XML way to develop AOP and annotations development principles are the same, so here mainly to introduce some uses. It should be introduced AOP namespace in XML, so first look at the elements AOP configurable


　　Listing: cut class

package com.ssm.chapter11.xml.aspect;

public class XmlAspect {

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

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

    public void afterThrowing() {
        System.out.println("after-throwing ......");
    }

    public void afterReturning() {
        System.out.println("after-returning ......");
    }

}

　　Without any notes, which means that we need to use XML to describe them the whereabouts of the Spring IoC container.
