Java 方面中的会话作用域bean

我无法将会话范围的bean自动连接到方面

我的外貌是这样的：

@Aspect
public class AuditAspect {

   Logger logger = LoggerFactory.getLogger(this.getClass());

   @Autowired
   private AuditService auditService;

   @Autowired
   private SessionData sessionData;


   @AfterReturning(value = "@annotation(fasthiAudit) && execution(* *(..))")
   public void audit(JoinPoint joinPoint, FasthiAudit fasthiAudit) {
      final String className = joinPoint.getTarget().getClass().getName();
      final String methodName = joinPoint.getSignature().getName();

      try {

         UserId userId = sessionData.getUserId();
         TenantId tenantId = sessionData.getTenantId();

      } catch (Exception e) {
         logger.error("Could not log audit entry for method name: " + methodName + " in class " + className, e);
      }

   }

}

@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SessionData {

   private UserId userId;
   private TenantId tenantId;

   public UserId getUserId() {
      return userId;
   }

   public void setUserId(UserId userId) {
      this.userId = userId;
   }

   public TenantId getTenantId() {
      return tenantId;
   }

   public void setTenantId(TenantId tenantId) {
      this.tenantId = tenantId;
   }
}

event.getServletContext().addListener(new RequestContextListener());

我的SessionData bean是会话范围的，如下所示：

@Aspect
public class AuditAspect {

   Logger logger = LoggerFactory.getLogger(this.getClass());

   @Autowired
   private AuditService auditService;

   @Autowired
   private SessionData sessionData;


   @AfterReturning(value = "@annotation(fasthiAudit) && execution(* *(..))")
   public void audit(JoinPoint joinPoint, FasthiAudit fasthiAudit) {
      final String className = joinPoint.getTarget().getClass().getName();
      final String methodName = joinPoint.getSignature().getName();

      try {

         UserId userId = sessionData.getUserId();
         TenantId tenantId = sessionData.getTenantId();

      } catch (Exception e) {
         logger.error("Could not log audit entry for method name: " + methodName + " in class " + className, e);
      }

   }

}

@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SessionData {

   private UserId userId;
   private TenantId tenantId;

   public UserId getUserId() {
      return userId;
   }

   public void setUserId(UserId userId) {
      this.userId = userId;
   }

   public TenantId getTenantId() {
      return tenantId;
   }

   public void setTenantId(TenantId tenantId) {
      this.tenantId = tenantId;
   }
}

event.getServletContext().addListener(new RequestContextListener());

在方面中，AuditService在OK中自动连接，SessionData不为null，但它会抛出一个异常，如

Method threw 'org.springframework.beans.factory.BeanCreationException' exception. Cannot evaluate se.reforce.fasthi.core.infrastructure.SessionData$$EnhancerBySpringCGLIB$$26c0d5bb.toString()

我添加了一个ContextLoaderListener来公开请求，如下所示：

@Aspect
public class AuditAspect {

   Logger logger = LoggerFactory.getLogger(this.getClass());

   @Autowired
   private AuditService auditService;

   @Autowired
   private SessionData sessionData;


   @AfterReturning(value = "@annotation(fasthiAudit) && execution(* *(..))")
   public void audit(JoinPoint joinPoint, FasthiAudit fasthiAudit) {
      final String className = joinPoint.getTarget().getClass().getName();
      final String methodName = joinPoint.getSignature().getName();

      try {

         UserId userId = sessionData.getUserId();
         TenantId tenantId = sessionData.getTenantId();

      } catch (Exception e) {
         logger.error("Could not log audit entry for method name: " + methodName + " in class " + className, e);
      }

   }

}

@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class SessionData {

   private UserId userId;
   private TenantId tenantId;

   public UserId getUserId() {
      return userId;
   }

   public void setUserId(UserId userId) {
      this.userId = userId;
   }

   public TenantId getTenantId() {
      return tenantId;
   }

   public void setTenantId(TenantId tenantId) {
      this.tenantId = tenantId;
   }
}

event.getServletContext().addListener(new RequestContextListener());

在SessionData bean中自动连接作为其他singelton bean中的代理，效果很好，但问题出现在方面

我错过了什么

多谢各位

/约翰头痛了几天后，我发现了这个问题。问题是我的Vaadin积分（我忘了在我的问题中提到）。我的vaadinui上的@Push注释对servlet造成了混淆，因此spring无法识别会话范围的bean。我解决了这个问题，将注释更改为：

@Push(transport= Transport.WEBSOCKET_XHR)

---

就是这样，现在会话范围的bean与singelton bean完美地结合在一起
