error at ::0 can't find referenced pointcut allMethod
今天在编写AOP代码如下：
package com.zy.spring;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.annotation.Before;
/***
* 定义切面aspect
*
* @author Douglas Lau
*
*/
@Aspect
public class SecurityHandler {
/***
* 定义Pointcut，Pointcut的名称是allMethod，此方法不能有返回值和参数，该方法只是一个标识
*
* Pointcut的内容是一个表达式，描述那些对象的那些方法(订阅Joinpoint)
*/
@Pointcut("execution(* addUser(..))")
private void allMethod() {
}
/***
* 定义Advice，标识在那些切个切入点何处技入此方法
*/
@Before("allMethod()")
//@Before("execution(* addUser(..))")
private void checkSecurity() {
System.out.println("---------安全性检查------------");
}
}
加载运行时总是提示如下错误

后来看Spring Recipes Covers Spring Framework 3后调用里边儿的方法又对了，更改后的AOP如下
package com.zy.spring;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.annotation.Before;
/***
* 定义切面aspect
*
* @author Douglas Lau
*
*/
@Aspect
public class SecurityHandler {
/***
* 定义Advice，标识在那些切个切入点何处技入此方法
*/
@Before("execution(* addUser(..))")
private void checkSecurity() {
System.out.println("---------安全性检查------------");
}
}
后成功了，现在还找不到原因何在，目前来说我水平不够！
