来自Spring的BeanCreationException，带有注解“@Context”和“@Loggable”

Question

我有使用Spring，Apache CXF和Jetty的Web应用程序。 Spring不喜欢在我的一个类中添加一个名为@Loggable的注释。

首先，注释@Loggable链接到类LogAspect，它记录请求和响应消息：

@Aspect 
@Component 
public class LogAspect { 

    ... 
    ... 
     @Around("execution(* * (..)) && @annotation(Loggable)") 
     public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable { 

      ... 
      if (returnValue != null) { 
       logger.infoRequestResponse(clazz, name, joinPoint.getArgs(), returnValue); 
      } else { 
       logger.infoRequestResponse(clazz, name, joinPoint.getArgs(), "void"); 
      } 
      return returnValue; 
     } 
} 

我猜它有事情做与@Context -annotation，什么被注射时。

该类是RESTful服务的实现。私有成员request有注解@Context它：

@org.springframework.stereotype.Service(value = "resellerService") 
public class ResellerServiceImpl implements ResellerService { 

    @Context 
    private HttpServletRequest request; 
... 
... 
    @Loggable 
    @Override 
    public Response isUserLoggedIn() { 
     Optional<ResellerSession> maybeSession = getSessionFromContext(); 
     return Response.ok(maybeSession.isPresent()).build(); 
    } 

的另外@Loggable -annotation上的isUserLoggedIn方法给了我以下异常：

所以我试图带走了@Context并将其添加到设置器方法中：

private HttpServletRequest request; 

@Context 
public void setRequest(HttpServletRequest request) { this.request = request; } 

这给我这个例外：

任何人有任何想法如何解决这个问题？

编辑

我不能表现出我的整个pom.xml的，但我确实有这条线 4.1.6.RELEASE

而构建的外观和工作正常。所有其他注释（如@Autowired）都可以正常工作。

Answer 1

我现在收到了关于如何解决此问题的帮助。简而言之，必须将@Context注释移到该类所实现的接口的方法中。

的解决方案如下：

1. 删除私有成员HttpServletRequest request及其@Context注释。

2. 将HttpServletRequest作为参数添加到使用它的方法中。 实施例：

   公共响应registerUser（HttpServletRequest的请求，...）{

3. 的@Context注释添加到REST接口代替。 实施例：

   @Path（ “注册/用户”）
   @POST
   @Consumes（ “应用程序/ JSON”）

   响应registerUser（@Context HttpServletRequest的HttpServletRequest的，..）;

Answer 2

问题出在spring-beans-4.1.6.RELEASE.jar。

希望你已经添加了Spring-beans-4.1.6.jar文件由于某些问题，Still Spring有时无法获取jar。在这种情况下，

从服务器中删除已存在的项目。

右键单击您的服务器，

点击干净，

右键单击您的服务器，

单击清除工作目录。

Spring MVC的也可以获取jar文件以这种方式，它的工作原理

右键点击你的Spring MVC项目，

构建路径 - >配置构建路径

一个标签就会出现，

选择添加外部JAR的按钮并添加所需的所有罐子。

之后，单击部署大会，

，单击Add按钮，

单击Java构建路径条目，

单击下一步，

选择所有正在出现的这个窗口上的罐子。

单击完成。

刷新您的项目，

运行该项目。

截至现在它会以正确的方式获取spring-beans-4.1.6.RELEASE.jar。希望能帮助到你。
