RegexpMethodPointcutAdvisor：正则方法切入点顾问
核心：
<property name="pattern" value=".*do.*"></property> 表示方法全名（包名，接口名，方法名）
运算符 名称 意义
. 点号 表示任意单个字符
+ 加号 表示前一个字符出现一次或者多次
* 星号 表示前一个字符出现0次或者多次
具体使用案例：
一个实现俩个方法的类：SomeServiceImpl
package cn.dawn.day16advisor02; /** * Created by Dawn on 2018/3/8. */ public class SomeServiceImpl { public void doSome() { System.out.println("do something"); } public void doAny() { System.out.println("do Any"); } }
一个实现任意增强的接口的方法：此处是实现后置增强的，我起名LoggerAfter
package cn.dawn.day16advisor02; import org.springframework.aop.AfterReturningAdvice; import java.lang.reflect.Method; /** * Created by Dawn on 2018/3/5. */ /*后置增强*/ public class LoggerAfter implements AfterReturningAdvice { public void afterReturning(Object o, Method method, Object[] objects, Object o1) throws Throwable { System.out.println("===============after=================="); } }
大配置文件：
<?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:aop="http://www.springframework.org/schema/aop" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--要增强的对象--> <bean id="service" class="cn.dawn.day16advisor02.SomeServiceImpl"></bean> <!--增强的内容--> <bean id="myadvice" class="cn.dawn.day16advisor02.LoggerAfter"></bean> <!--顾问--> <bean id="myadvisor" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice" ref="myadvice"></property> <property name="pattern" value=".*do.*"></property> <!--上面那个name还有一个可以是patterns，value可以写多个正则。用逗号分割，匹配多个正则，方法名只要合适其中一个正则就增强--> </bean> <!--代理工厂bean--> <bean id="proxyfactory" class="org.springframework.aop.framework.ProxyFactoryBean"> <!--要增强的对象--> <property name="target" ref="service"></property> <!--增强的内容--> <property name="interceptorNames" value="myadvisor"></property> </bean> </beans>
单测方法：
package cn.dawn.day16advisor02; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * Created by Dawn on 2018/3/3. */ public class test20180310 { @Test /*aop代理工厂bean异常增强*/ public void t01(){ ApplicationContext context=new ClassPathXmlApplicationContext("ApplicationContext-day16advisor02.xml"); SomeServiceImpl service = (SomeServiceImpl) context.getBean("proxyfactory"); service.doSome(); service.doAny(); } }
