XML方式开发AOP与注解开发原理是相同的,所以这里主要介绍一些用法即可。这里需要在XML中引入AOP的命名空间,所以先来了解一下AOP可配置的元素

代码清单:切面类
代码清单:spring-cfg4.xml
代码清单:测试类

代码清单:切面类
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 ......"); } }
没有任何的注解,这就意味着需要我们使用XML去向Spring IoC容器描述它们。
代码清单:spring-cfg4.xml
xml version=‘1.0‘ encoding=‘UTF-8‘ ?> beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd"> bean id="xmlAspect" class="com.ssm.chapter11.xml.aspect.XmlAspect"/> bean id="roleService" class="com.ssm.chapter11.xml.service.impl.RoleServiceImpl"/> aop:config> aop:aspect ref="xmlAspect"> aop:pointcut id="printRole" expression="execution(* com.ssm.chapter11.xml.service.impl.RoleServiceImpl.printRole(..))"/> aop:before method="before" pointcut-ref="printRole"/> aop:after method="after" pointcut-ref="printRole"/> aop:after-throwing method="afterThrowing" pointcut-ref="printRole"/> aop:after-returning method="afterReturning" pointcut-ref="printRole"/> aop:around method="around" pointcut-ref="printRole"/> aop:aspect> aop:config> beans>
代码清单:测试类
public class Main { public static void main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("ssm/chapter11/spring-cfg4.xml"); RoleService roleService = ctx.getBean(RoleService.class); Role role = new Role(); role.setId(1L); role.setRoleName("role_name_1"); role.setNote("note_1"); roleService.printRole(role); } }
