我是AOP的新手.我有这样的问题.

package org.suman.Aspect;

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

@Aspect
public class LoginAspect {
    //@Before("execution(public String getName())")
    //@Before("execution(public String org.suman.Model.Triangle.getName())")
    //@Before("execution(* get*())")
    //@Before("execution(* get*(..))")
    //@Before("execution(* org.suman.Model.*.get*())")

    //@Before("execution(* get*())&& within(org.suman.Model.Circle)")
    @Before("execution(* get*())&& allCircle()")
    //@Before("allGetters() && allCircle()")
    public void LoginAdvice()
    {
        System.out.println("Advice run.. getMethod is called");
    }

    @Before("execution(* get*())")
    //@Before("allGetters()")
    public void SecondAdvice()
    {
        System.out.println("this is a second Advice");
    }
    @Pointcut("execution(* get*())")
    public void allGetters(){}

    //@Pointcut("execution (* * org.suman.Model.Circle.*(..))")
    @Pointcut("within(org.suman.Model.Circle)")
    public void allCircle(){}

} 

当使用切入点时,方法allGetters()为LoginAdvice方法,如果我使用@Before("execution(*get*())"然后没有错误但是如果我使用@Before("allGetters()")则会给出错误" java.lang.IllegalArgumentException::: 0处的错误找不到引用的切入点allGetters

如果我使用@Before("execution(*get*())&&(org.suman.Model.Circle)")而不是方法名称,它可以工作.

我的xml是这样的:

使用Java 7的aspectj插件有哪些适当的配置/版本/插件版本？

我正在尝试从Java 6升级到Java 7,而aspectj编译器似乎没有编译Java 7.我在Aspectj插件和maven编译器插件的插件配置中将java源和目标版本指定为1.7.我在我的代码中引入了Java7特定的语法,添加了几个语言功能,如switch in switch和diamond operator.在构建期间,我从aspectj获取有关Java7语法的错误.事情出错的第一个迹象是:

[INFO] --- aspectj-maven-plugin:1.4:compile (default) @ site ---
[ERROR] Cannot switch on a value of type String. Only int values or enum constants are permitted
[ERROR] Cannot instantiate the type HashSet<?>
[ERROR] Syntax error on token "<", ? expected after this token

如果我从aspectj maven插件中删除执行部分,因此它不运行,并使用mvn clean install,新代码编译正常.所以我认为这是与aspectj错误配置的东西.这是我的插件配置:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java-version>1.7</java-version>
    <org.aspectj-version>1.6.11</org.aspectj-version>
