spring的aop错误

zr_dixuexiongying 2012-09-02 06:34:26
我用的是spring2.5开发的aop,可是做拦截的时候报错,代码如下:
package cn.itcast.service;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

/**
*
* 切面
*
*/
@Aspect
public class MyInterceptor {
@Pointcut("execution (* cn.itcast.service.impl.PersonServiceBean.*(..))")
private void anyMethod() {}

@Before("anyMethod()")
public void doAccessCheck(){
System.out.println("前置通知");
}
}


package cn.itcast.service;

public interface PersonService {
public void save(String name);
public void update(String name,Integer id);
public String getPersonName(Integer id);
}

package cn.itcast.service.impl;

import cn.itcast.service.PersonService;

public class PersonServiceBean implements PersonService {

public void save(String name) {
System.out.println("我是save()方法");
}

public void update(String name, Integer id) {
System.out.println("我是update()方法");
}

public String getPersonName(Integer id) {
System.out.println("我是 getPersonName()方法");
return "xxxx";
}

}

package junit.test;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.service.PersonService;

public class SpringAOPTest {

@BeforeClass
public static void setUpBeforeClass() throws Exception {
}

@Test public void interceptorTest(){
ApplicationContext cxt = new ClassPathXmlApplicationContext("beans.xml");
PersonService personService = (PersonService)cxt.getBean("personService");
personService.save("xxxxx");
}

}


<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

错误信息如下:

哈哈，我明天亲临了这个问题，那些bean都是没有问题的，主要是你在定义的切面的时候出现了问题， 这是我昨天小小总结了一下，你看哈行不行，不行再留言： http://blog.csdn.net/qq445422083/article/details/8194705

<aop:config> <aop:aspect id="asp" ref="myInterceptor"> <aop:pointcut id="mycut" expression="execution(*cn.itcast.service.imp.PersonServiceBean.*(java.lang.String,..))"/> <aop:before pointcut-ref="mycut" method="doAccessCheck"/> </aop:aspect> </aop:config> 把你方法里面的注解去掉 在配置文件中加入这个试试 要用注解你全部都用注解 别用一半

出现这种错误需要检查JDK版本与易用的aspectJrt的版本,如果你的JDK是1.6那么需要下载最新的aspectj-1.6.6.jar 或者改变你的JDK版本

<bean id="personService" class="cn.itcast.service.PersonServiceBeanImpl "></bean>
service后面接实现类 试试/

创建service bean的时候出错了，检查bean是否被创建了

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personService' defined in class path resource [beans.xml]: Initialization of bean failed
创建'personService' 的时候出错了，先检查一下，bean有没有被创建

现在问题并不是创建的bean类问题,而是拦截器的问题,因为我把拦截器的类和配置的bean去掉就可以正常运行了,只是我不明白我的拦截器哪里出现了问题,而且我也只是测试了一个前置通知的方法啊!

创建bean怎么就错了呢?明明创建了bean类啊!
<bean id="personService" class="..............."/> class不就是指向的实现类吗?

Spring AOP原理详解及实例
Spring AOP原理详解及实例 1.Spring AOP简介 在软件业，AOP为Aspect Oriented Programming的缩写，意为：面向切面编程，通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。AOP是OOP的延续，是软件开发中的一个热点，也是Spring框架中的一个重要内容，是函数式编程的一种衍生范型。利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻...
