spring的aop错误
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");
}
}
