在 amqp rpc 客户端中创建一个 spring 会话
Create a spring session in amqp rpc client
我开发了 spring 远程 amqp rpc 应用程序。
这对于不将 bean 与 Scope SESSION 一起使用的方法非常有效。
对于其他方法，客户端无法使用spring会话，我得到这个异常
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.userSession': Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

所以我会在 rabbit mq
上创建和使用 spring 会话
首先，我设法在 RPC 调用中传递了 sessionId
在服务器上我添加了一个属性
class SessionDefaultRemoteInvocationFactory : DefaultRemoteInvocationFactory() {
override fun createRemoteInvocation(methodInvocation: MethodInvocation?): RemoteInvocation {
return super.createRemoteInvocation(methodInvocation)
.apply { addAttribute("sessionId", RequestContextHolder.currentRequestAttributes().sessionId) }
}
}
在客户端我可以阅读
class SessionDefaultRemoteInvocationExecutor : DefaultRemoteInvocationExecutor() {
override fun invoke(invocation: RemoteInvocation?, targetObject: Any?): Any {
if (invocation is RemoteInvocation) {
invocation.getAttribute("sessionId")?.let {
val sessionId = it.toString()
SecurityContextHolder.getContext().authentication = AnonymousAuthenticationToken(sessionId,
"anonymousUser", listOf(SimpleGrantedAuthority("ROLE_ANONYMOUS")))
val attr = RequestContextHolder.currentRequestAttributes() as ServletRequestAttributes // <= ERROR here
attr.request.getSession(true)
}
}
return super.invoke(invocation, targetObject)
}
}
但我无法使用它来创建 spring 会话
如何在此非 http 上下文中创建 spring 会话
我尝试创建一个请求上下文侦听器
@Configuration
@WebListener
class MyRequestContextListener : RequestContextListener()
但同样的错误
目前我绕过 spring 会话并注入了一个具有相同行为的 bean
@Component
@Scope("singleton")
class EngineThread(var engineSession: ThreadLocal<EngineSession> = ThreadLocal()) : IEngineSession by engineSession.getOrSet( { EngineSession() })
@Component
@Profile("engine & !test")
class SessionDefaultRemoteInvocationExecutor(val engineThread: EngineThread) : DefaultRemoteInvocationExecutor() {
val engineSessionStore : MutableMap<String, EngineSession> = mutableMapOf()
override fun invoke(invocation: RemoteInvocation?, targetObject: Any?): Any {
if (invocation is RemoteInvocation) {
invocation.getAttribute(SESSION_ID)?.let {
val sessionId = it.toString()
SecurityContextHolder.getContext().authentication = AnonymousAuthenticationToken(sessionId,
"anonymousUser", listOf(SimpleGrantedAuthority("ROLE_ANONYMOUS")))
if (! engineSessionStore.contains(sessionId)) {
engineSessionStore.put(sessionId, EngineSession())
}
engineThread.engineSession.set(engineSessionStore.getValue(sessionId))
}
}
return super.invoke(invocation, targetObject)
}
}
工作已完成，但我对这个解决方案不是很满意
（我将通过 softreference 添加 clean ......但所有这些工作都是重新发明会话而不是使用 spring 会话）
