Java Spring AOP注入PortletRequest

我正在尝试在我的方面类中注入portletrequest

@Autowired(required = true)
private PortletRequest request;

@Before("execution(* de.ac.mis.dao.*.getSessionFactory())")
public void setUsername() {
    System.out.println("Now I'm setting the username " + this.request);
}

只给了我一个

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No matching bean of type [javax.portlet.PortletRequest] found for dependency: 
expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

例外情况

但是我可以自动连线

HttpServletRequest

-我遗漏了什么吗？

好的，在一些实验之后解决了它，也许它对其他人有用

@Before("execution(* de.ac.mis.dao.acDynamicUserSessionFactory.getSessionFactory())")
public void setUsername(JoinPoint joinPoint) {
    acDynamicUserSessionFactory dao = (acDynamicUserSessionFactory) joinPoint.getTarget();
    RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
    String userName = "";
    if (requestAttributes instanceof PortletRequestAttributes) {
        PortletRequest request = ((PortletRequestAttributes) requestAttributes).getRequest();
        userName = request.getRemoteUser();
    } else if (requestAttributes instanceof ServletRequestAttributes) {
        HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
        userName = request.getRemoteUser();
    }
    dao.setUserName(userName);
    this.log.debug("acUserSessionfactory was set for user: " + userName);
}

对于这些配置来说，重要的是请求资源（Portlet或Servlet）必须在spring上下文中运行，否则此时没有可用的requestattributes。

在查看JavaDocs后，我选择使用resolveReference，它声明：

至少：密钥的HttpServletRequest/PortletRequest引用 “请求”，以及密钥的HttpSession/PortletSession参考 “会议”

示例代码：

RequestAttributes attrs = RequestContextHolder.getRequestAttributes();
// According to JavaDoc, PortletRequest should be available
PortletRequest request = (PortletRequest) attrs.resolveReference("request");
