ResourceHttpRequestHandler返回错误（缓存？）资源

我有一个Spring（3.2.2）后端为静态资源提供jQuery Mobile前端。资源驻留在地图/ webapp/resources/images下。已经存在于此映射中的资源已正确返回，但是当我添加新资源并尝试访问它（使用浏览器）时，我找不到404。当我从地图中删除现有资源时，仍然可以根据请求找到它。我认为这是一些缓存问题？ResourceHttpRequestHandler返回错误（缓存？）资源

的web.xml

* UPDATE：*

我在每次资源更新后重新加载（停止/启动）在Eclipse Juno SR2中运行的apache-tomcat-7.0.32。也试图关闭日食并重新启动，没有任何运气。

它现在正在工作。 @ kryger指出我的问题（tomcat发布，而不是resourceHttpRequestHandler）。我打开服务器选项卡，显示项目已同步。我在/ image映射中添加了一个资源，仍然同步。我注意到第二个战争项目（对于web服务）的引用，目前还没有被使用，所以我删除了这个引用。现在，当我添加，修改或删除正在重新发布的资源时，甚至无需重新启动服务器。

让我猜...你申请后修改src/main/resources/目录的内容启动？由于使用target/classes/，源文件夹中的更改对正在运行的应用程序将不可见。 src/文件夹甚至不在类路径中。 您可以通过在target/目录中重复您的步骤来测试此理论。

如果这不是你的你的问题的原因，增加你的构建工具（Maven的？）和servlet容器的信息（Tomcat的？码头？独立？嵌入？）会有所帮助。

我在每次资源修改后停止/启动应用程序。我根据你的评论更新了我的问题。 – user2099506 2013-04-22 16:21:09

目前还不清楚你看到哪些“僵尸”资源。只是为了澄清：** 1 **。资源/有文件'a.png'和'b.png'。 ** 2 **。你启动服务器。 ** 3 **。你看到'a.png'和'b.png' ** 4 **。你停止服务器。 ** ** 5。你删除'b.png'，添加'd.png'（在'target/classes'中的src/main/resources'？** 6 **。你重新启动服务器** 7 **。你仍然可以请参阅第1页的状态？或者...？ – kryger 2013-04-22 19:13:13

是的，我采取了所有描述的步骤，我只在map/src/main/webapp/resources/images中进行了修改，实际上这些资源甚至不在/ target map。重启后，我看到a.png和b.png，d.png给出了404。在项目目录中查找时，我发现a.png和d.png中的资源位于/ src/main/webapp /资源/图像，a.png和b.png位于.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/oiga-frontend/resources/images中。 – user2099506 2013-04-22 21:05:54
