Grails没有找到线程绑定的请求 [英] Grails No thread-bound request found

问题描述

我正在使用Grails服务闭包来执行异步HTTP请求到另一个Web应用程序。使用 Grails 1.3.9 ，我在这里非常有限。代码在一个线程内运行。它是从一个计划任务和几个函数调用中调用的。我得到的错误如下：

错误：

  java。 lang.IllegalStateException：找不到线程绑定请求：您是否在实际Web请求之外引用请求属性，或在原始接收线程之外处理请求？如果实际上在Web请求中运行并仍然收到此消息，则代码可能在DispatcherServlet / DispatcherPortlet之外运行：在这种情况下，请使用RequestContextListener或RequestContextFilter来公开当前请求。 
  

CODE：

  Thread.start {
 
 def http = new HTTPBuilder（grailsApplication？.config？.smsConfig？.smsServiceAddress）; 
 
尝试{
 http.request（POST）{
 
 body = bodyRequest; 
 requestContentType = ContentType.JSON 
 
 response.success = {resp  - > 
 printlnSUCCESS！$ {resp.status}
 
 def user = RequestContextHolder.currentRequestAttributes（）。getSession（）。user 
 
 if（user！= null）{
 if（termin）{
 termin.withTransaction {
 
 try {
 //做所需动作
 
} catch（ e）{
 println（e）; 
 
 
 
 
 
 
 response.failure = {resp  - > 
 printlnFAILURE请求失败，状态为$ {resp.status}，响应主体为[$ {resp.entity.content.text}]
 System.out << 
 
 
 $ b $ //在这里捕获错误
 catch（e）{
 log.errorError：+ e; 
 
 
 
 
 $ b我已经尝试在web.xml中添加这个选项
 < listener> 
< listener-class> org.springframework.web.context.request.RequestContextListener< / listener-class> 
  
 
 
  
 
 
 
以及WebXmlConfig。 groovy  
 
 
  listener.add = true 
 listener.classNames = [org.springframework.web.context.request。 RequestContextListener] 
  
但都没有帮助 
 
解决方案
这是没有很好的文档记录，或者你可以给你发送螺旋：       这个：
  / * 
 *修复找不到线程绑定请求：您是指请求属性
 * / 
 def webRequest = RequestContextHolder.getRequestAttributes（）
 if（！webRequest）{
 def servletContext = ServletContextHolder.getServletContext（）
 def applicationContext = WebApplicationContextUtils 。 getRequiredWebApplicationContext（servletContext）
 webRequest = grails.util.GrailsWebMockUtil.bindMockWebRequest（applicationContext）
} 
  
您需要在build.gradle中进行spring测试 
 
 
  compile'org.springframework：spring-test：2.5' 
  
有一个grails 2分支，所以如果它是grails 2， / p> 
I am using a Grails service closure to perform a async HTTP request to another web application. Using Grails 1.3.9, I am very limited here.  The code runs inside a thread. It is called from a scheduled job and from several function calls. The error I get is below: 


ERROR: 
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.
CODE:
    Thread.start {

        def http = new HTTPBuilder(grailsApplication?.config?.smsConfig?.smsServiceAddress);

        try {
            http.request(POST) {

                body = bodyRequest;
                requestContentType = ContentType.JSON

                response.success = { resp ->
                    println "SUCCESS! ${resp.status}"

                    def user = RequestContextHolder.currentRequestAttributes().getSession().user

                    if (user != null) {
                        if (termin) {
                            termin.withTransaction {

                                try {
                                    // do desired action

                                } catch (e) {
                                    println(e);
                                }

                            }
                        }

                    }
                }
                response.failure = { resp ->
                    println "FAILURE request failed with status ${resp.status}, response body was [${resp.entity.content.text}]"
                    System.out << resp
                }
            }
        }
        //here error is caught
        catch (e) {
            log.error "Error: " + e;
        }
    }
I have tried adding this options to web.xml 
    <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>


and also this to WebXmlConfig.groovy
    listener.add = true
listener.classNames = ["org.springframework.web.context.request.RequestContextListener"]
but both did not help
解决方案
This is something that isn't well documented or can you send you spirals:

Try this:
/*
* Fix for No thread-bound request found: Are you referring to request attributes
*/
def webRequest = RequestContextHolder.getRequestAttributes()
if(!webRequest) {
    def servletContext  = ServletContextHolder.getServletContext()
    def applicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext)
    webRequest =  grails.util.GrailsWebMockUtil.bindMockWebRequest(applicationContext)
}
You will need spring test in your build.gradle
  compile 'org.springframework:spring-test:2.5'
There is a grails 2 branch so follow the same class in the other branch if it is grails 2
