AspectJ：一个方面内多个建议的执行顺序（优先级）

类使用编译时编织。

想象一下我有一个方面类：

@Aspect
public class SecurityInterceptor {

    @Pointcut("within(@org.springframework.stereotype.Controller *)")
    public void beanAnnotatedWithController() {}

    @Pointcut("execution(public * *(..)) && args(*,httpReq)")
    public void publicMethods(HttpServletRequest httpReq) {}

    @Pointcut("beanAnnotatedWithController() && publicMethods(httpReq)")
    public void controllerMethods(HttpServletRequest httpReq) {}

    @Pointcut("execution(public * *(..)) && args(httpReq)")
    public void publicMethodsRequestOnly(HttpServletRequest httpReq) {}

    @Pointcut("beanAnnotatedWithController() && publicMethodsRequestOnly(httpReq)")
    public void controllerMethodsOneArg(HttpServletRequest httpReq) {}


    @Around(value = "controllerMethods(httpReq)")
    public Object populateSecurityContext(final ProceedingJoinPoint joinPoint, HttpServletRequest httpReq) throws Throwable {
        return popSecContext(joinPoint, httpReq);
    }

    @Around(value = "controllerMethodsOneArg(httpReq)")
    public Object populateSecurityContextOneArg(final ProceedingJoinPoint joinPoint, HttpServletRequest httpReq) throws Throwable {
        return popSecContext(joinPoint, httpReq);
    }

}

正确的使用方法是什么@DeclarePrecedence来确定执行顺序？

请阅读“建议优先顺序”段落语言语义 http://www.eclipse.org/aspectj/doc/next/progguide/semantics-advice.htmlAspectJ 文档的部分。

的优先级aspects可以显式声明，优先级单一方面的建议AFAIK 由文档中描述的规则确定并且无法更改。所以@DeclarePrecedence在这种情况下不会帮助您，只能更改方面文件中的建议顺序。
