Question

我正在努力实施STRUTS SPRING和HIBERNATE INTEGRATION ON ONLINE EXAMINATION。使用apache tomcat 7.0.42在Eclipse Kepler中运行项目时，它会抛出以下错误

**HTTP Status 404 - /OnlineExam/registration.jsp**
**Description:**The requested resource is not available.

在控制台日志中，出现以下内容，

struts.xml中

请帮帮我朋友。我不知道为什么会这样。无论如何，谢谢你提前...... !!!

Answer 1

我认为你错过了“struts2-spring-plugin-2.1.6.jar”文件，请在你的类路径中查看

Answer 2

我得到了同样的错误，然而，添加jar并没有解决我的问题。

错误说明：Unable to load configuration. - action - file:/C:/workspace/.metadata/.plugins/org.eclipse.wst.server.core/tmp3/wtpwebapps/iSAS/WEB-INF/classes/ struts.xml：16：73

第16行的struts.xml存在问题，即

<action name="userRegistration" 方法=＆＃34; {1}＆＃34; class="userRegistration">

struts尝试从类userRegistration加载名为{1}的方法。可能该方法不存在，因为它是一个无效的Java名称。我不确定struts是否接受像{1}那样的表示法来引用类中的第一个方法（可能不是），但在我的情况下，那就是问题：在struts.xml中，在action标签中，我是引用一个名称拼写错误的方法，因此struts试图找到一个不存在的方法，导致此错误 - 无法加载配置。

Answer 3

修复了问题。希望解决方案对其他人有用：

struts.xml文件必须出现在WebContent下 - WEB-INF - classes - 使用eclipse时的struts.xml

我犯的错误是当我做了一个干净的项目时，它曾用于删除类文件夹下的文件，所以请确保该特定文件存在。

无法在Struts中加载配置
