Question

我有一个基本的Spring 4 MVC项目设置。启动服务器之后，该站点可以访问并运行，直到我在代码中更改某些内容，之后当我单击我站点中的链接进行导航时，它不响应来自浏览器的任何类型的请求（GET / POST）。当我点击登录时，我在控制台中获得以下内容，

DEBUG DispatcherServlet:861 - DispatcherServlet with name 'dispatcherServlet' processing GET request for [/springapp/login]
[artifact:mvn] 2016-01-12 14:06:25 DEBUG RequestMappingHandlerMapping:318 - Looking up handler method for path /login

我的应用中登录的网址是http://localhost:8080/springapp/login。

对于任何后续请求，都会显示相同的“查找路径/something”消息的处理程序方法，但是localhost服务器没有响应。我等了15分钟，但没有任何回应。我在eclipse中使用嵌入式jetty作为我的服务器。我禁用了防火墙并卸载了防病毒软件，但这没有帮助。

的web.xml

<servlet>
<servlet-name>densoServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/config/springContext.xml</param-value>
  </init-param>
</servlet>

<servlet-mapping>
   <servlet-name>densoServlet</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>

我每次都要重新启动服务器以测试我的代码，这非常耗时。什么可以阻止来自服务器的响应？

编辑：仅当我在代码中进行更改时，服务器才会停止响应。停止服务器后，它抛出线程无法停止，

更新

我测试了其他系统中的相同工作区，它在那里工作得很好。所以代码不是问题所在。它不是日食，因为我使用STS并没有得到任何回应。我使用JDK的jVisualVM在eclipse pid上进行了一个Thread转储，以下是线程转储跟踪，http://pastebin.com/9HQFSebM

Answer 1

很长一段时间后，我发现了问题所在。正如他们所建议的那样联系Jrebel支持团队，我使用的是jrebel的旧版本（JRebel Legacy Agent 6.2.1 (201506091436)）。

升级到最新版本（JRebel Legacy Agent 6.2.3）解决了我的问题。似乎有一些错误修复了我没有更新的新版本。
