Grails项目-Servlet调用-ClassNotFoundException:javax.Servlet.AsyncContext

我正在使用

• intellij idea ultimate 12..4
• Grails2.2.0
• BuildConfig.groovy文件中的grails.servlet.version=“2.5”

并实现了简单的servlet post请求。使用RESTClient进行post请求时，我发现以下场景

情景：

• 当我在本地使用时，效果很好。URL:localhost:9090/testProject/api/testReport

• 但当我在本地服务器中部署它时，下面的错误消息显示URL:192.168.1.10:9090/testProject/api/testReport

本地服务器配置与localhost相同

code:

经过几天的搜索和整合，我找到了解决方案

为什么ClassNotFoundException异常最常发生在这里这篇文章真的很好

问题的主要原因显示日志java.lang.ClassNotFoundException:javax.servlet.AsyncContext

这意味着它找不到javax.servlet-3.0提供的asyncContext类。在Servlet2.5中，缺少它

我在本地主机上运行，但在本地服务器192.168.1.10上运行。在给定的链接中，apachedoc表示servlet版本

 So the solution is either anyone upgrade the Apache Tomcat 6 to Apache Tomcat 7
 or posting the file javax.servlet-3.0 in Apache Tomcat 6 lib folder.
 [Here][3] is the jar file.

您还可以强制Grails应用程序使用Servlet2.5 在BuildConfig.groovy中

grails.servlet.version=“2.5”

希望能有帮助

可能是Hello WillTryCodelt的副本，我已经看到了您在问我的问题之前提供的问题和评论。我没有解决我的问题。。。。根据答案，尝试将grails.servlet.version更改为3.0Tried，但没有得到解决方案。我想图书馆的路不见了。。。。但是找不到在哪里写。。。
