来自 Spring 的 BeanCreationException，带有注释“@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 class 之一的方法中添加一个名为 @Loggable 的注释。

首先，注释 @Loggable 链接到 class 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;
        }
}

我猜它与 @Context-注释有关，以及什么时候被注入。

class 是 RESTful 服务的实现。私有成员request上面有注解@Context：

@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();
    }

在 isUserLoggedIn 方法上添加 @Loggable-注释会出现以下异常：

所以我尝试删除请求中的 @Context，并将其添加到 setter 方法中：

private HttpServletRequest request;

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

这给了我这个例外：

有人知道如何解决这个问题吗？

编辑

我无法显示整个 pom.xml，但我确实有这一行 4.1.6.RELEASE

构建看起来和工作正常。 @Autowired 等所有其他注释都可以正常工作。

Answer 1

问题出在 spring-beans-4.1.6.RELEASE.jar.

希望您已添加 Spring-beans-4.1.6.jar 文件仍然 Spring 有时由于某些问题无法获取 jar。在这种情况下

从您的服务器中删除现有的项目。

右键单击您的服务器，

点击清理，

右键单击您的服务器，

单击清除工作目录。

Spring MVC也可以通过这种方式获取jar文件，有效

右键单击您的 Spring MVC 项目，

构建路径 -> 配置构建路径

将出现一个标签，

Select 添加外部 JAR 按钮并添加您想要的所有 jar。

之后，点击部署程序集，

点击添加按钮，

单击 Java 构建路径条目，

点击下一步，

Select 所有出现在 window 上的罐子。

单击“完成”。

刷新您的项目，

运行项目。

截至目前，它将以正确的方式获取 spring-beans-4.1.6.RELEASE.jar。希望对你有帮助。

Answer 2

我现在已经收到有关如何解决此问题的帮助。简而言之，必须将 @Context 注释移动到 class 实现的接口方法中。

解决方法如下：

删除了私有成员 HttpServletRequest request 及其 @Context 注释。
将 HttpServletRequest 作为参数添加到使用它的方法中。示例：

public 响应 registerUser(HttpServletRequest 请求,...) {
改为将 @Context 注释添加到 REST 接口。示例：

@Path("register/user")
@POST
@Consumes("application/json")

响应注册用户(@Context HttpServletRequest httpServletRequest, ..);
