我定义了一个类，实现了ThrowsAdvice接口，在afterThrowing方法里输出“拦截异常”，可它不起作用，控制台只是输出普通的异常信息，没有输出我自己写的“拦截异常”几个字
Hi类
- Java code
public class Hi { public void sayHI(){ System.out.println("i say hi"); try { throw new Exception("my exception"); } catch (Exception e) { e.printStackTrace(); } }}ThrowsAdvice类：
- Java code
import org.springframework.aop.ThrowsAdvice;public class MyThrowsAdvice implements ThrowsAdvice{ public void afterThrowing(Exception ex){ System.out.println("拦截异常"); System.out.println(ex); }}applicationContex.xml
- HTML code
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"> <bean id="hi" class="Hi"/> <bean id="throw" class="MyThrowsAdvice"/> <bean id="proxy" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="target"> <ref bean="hi"/> </property> <property name="interceptorNames"> <list> <value>proxy</value> </list> </property> </bean></beans>
Test.java
- Java code
import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test { public static void main(String[] args) { ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml"); Hi h=(Hi)ac.getBean("proxy"); h.sayHI(); }}

不要在方法里捕获
