本文介绍了HTTP 状态 404 – 应用程序运行时未找到的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的 spring 应用程序有问题.当我运行它时，我遇到了以下异常:它工作正常，但应用程序没有看到 .jsp 文件中的变化并且每次都加载相同的页面.我过去遇到过这个问题吗?但不幸的是我无法解决这个问题，并重新创建了项目.

我的项目结构:

我的spring-mvc-demo-servlet.xml文件:

<!-- 第三步:添加对组件扫描的支持--><context:component-scan base-package="com.spring"/><!-- 第 4 步:添加对转换、格式化和验证支持的支持 --><mvc:注解驱动/><!-- 第五步:定义Spring MVC视图解析器--><豆class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/view/"/><property name="suffix" value=".jsp"/></bean></豆类>

我的web.xml:

<display-name>spring-mvc-demo</display-name><!-- Spring MVC 配置 --><!-- 第一步:配置Spring MVC Dispatcher Servlet --><小服务程序><servlet-name>调度程序</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>/spring-mvc-demo-servlet.xml</param-value></init-param><启动时加载>1</启动时加载><!-- 步骤 2:为 Spring MVC Dispatcher Servlet 设置 URL 映射 --><servlet-mapping><servlet-name>调度程序</servlet-name><url-pattern>/</url-pattern></servlet-mapping></web-app>

可能是 artifacts 或 tomcat 配置有问题，因为我在尝试解决此错误时对其进行了更改.

我的pom.xml:

更新:::我创建了一个新的artfacts，并收到了一个新的错误:

我的工件:

虽然web.xml有问题.

错误是:无法解析 servlet 'dispatcher'.

Pom.xml 也在上面更新.

解决方案

至少我解决了我的问题.正如 M. Deinum 所说，我已将 web.xml、view 和 spring-mvc-demo-servlet.xml 移至 WEB-INF，因为我有:

<property name="prefix" value="/WEB-INF/view/"/><property name="suffix" value=".jsp"/></bean>

然后我重新生成了一个Artifacts.

I have a problem with my spring app. While I run it, I am getting below exception: It had worked correctly, but app didn't see changes in .jsp files and loaded the same page every time. I faced with this problem in the past? but unfortunately I couldn't resolve this, and recreated project.

My project struct:

My spring-mvc-demo-servlet.xml file:

Maybe there is a problem with artifacts or tomcat configuration, because I changed it while tried resolve this error.

Error is: Can not resolve servlet 'dispatcher'.

Pom.xml updated too above.

解决方案

At least I resolved my problem. As told M. Deinum I have moved an web.xml, view, and spring-mvc-demo-servlet.xml to WEB-INF, because I have:

<bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" />
    </bean>

Then I regenerated an Artifacts.
