Spring MVC ViewResolver 未映射到 HTML 文件

Question

我无法让 spring mvc 解析 .html 视图文件。

我有以下视图文件夹结构：

WEB-INF
      `-views
            |- home.jsp
            `- home.html

我有一个简单的 hello world 控制器方法，它只打印一条消息 并返回视图名称“home”。我有一个 home.jsp 文件，但想要 改为使用 home.html。

<!-- Working servlet mapping --> 
<servlet-mapping>
    <servlet-name>spaceShips</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<!-- working servlet context -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <beans:property name="prefix" value="WEB-INF/views/" />
    <beans:property name="suffix" value=".jsp" /> 
</beans:bean>

当我点击 spaceships/home 时，控制器会打印出 hello world 消息，我会看到 home.jsp 查看没有问题。

问题是当我将后缀更改为 .html 时。

更改后缀并导航到 /home 后，控制器会打印 消息但是我在浏览器中看到 404 错误，在控制台中看到以下内容： 警告：未找到带有 URI [/spaceships/WEB-INF/views/home.html] 的 HTTP 请求的映射

澄清一下：

<!-- not working with .html -->
<servlet-mapping>
    <servlet-name>spaceShips</servlet-name>
    <!-- I have tried /* here as well without success -->
    <url-pattern>/</url-pattern>
</servlet-mapping>

<!-- not working with .html-->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
    <beans:property name="prefix" value="WEB-INF/views/" />
    <beans:property name="suffix" value=".html" /> 
</beans:bean>

我已经检查了分解的战争文件夹，并且可以确认两个主文件都存在。

有没有人遇到过这样的事情？

最后一段控制台消息：

INFO: Server startup in 5256 ms
Hello, World!
Jul 27, 2014 12:52:01 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/spaceships/WEB-INF/views/home.html] in DispatcherServlet with name 'spaceShips'

感谢阅读。

=========== 解决方案============

以下（丑陋的）配置解决了这个问题。可能有一些方法可以解决这个问题，但如果您遇到同样的问题，您也许可以从中拼凑出一个解决方案。

文件夹结构：

 WEB-INF
       `-static
              |-html
                    `-home.html
              |-css
              `-img

控制器方法：

 @RequestMapping(value = "/home")
 public String goHome() { 
      System.out.println("lolololololol");
      return "static/html/home";
 }

弹簧配置：

 <resources mapping="/static/**" location="/WEB-INF/static/" />

 <beans:bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <beans:property name="prefix" value="" />
      <beans:property name="suffix" value=".html" />
 </beans:bean>

Answer 1

检查一下在 Spring mvc 中映射 html 文件（详细步骤在答案中给出）：

Which spring view resolver plays nice with angularjs?

简单来说：

为了在spring中使用静态资源(html,css,img,js)，使用如下目录结构：

src/
   package/
   LayoutController.java
WebContent/
   WEB-INF/
    static/
      html/
       layout.html
      images/
       image.jpg
      css/
       test.css
      js/
       main.js
     web.xml
    springmvc-servlet.xml


@Controller 
public class LayoutController {

 @RequestMapping("/staticPage") 
public String getIndexPage() { 
return "layout.htm"; 

} }




<!-- in spring config file -->
 <mvc:resources mapping="/static/**" location="/WEB-INF/static/" />

layout.html

<h1>Page with image</h1>
<img src="/static/img/image.jpg"/>

Answer 2

这是因为通常*.jsp 样式的 uri 模式由 servlet 容器处理，在此特定实例中，*.html 不由容器处理，而是将路径委托给不知道如何处理的 Spring MVC渲染这些扩展。

例如，如果您使用的是 tomcat，您会在 conf/web.xml 文件下看到这些条目：

<servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>*.jsp</url-pattern>
    <url-pattern>*.jspx</url-pattern>
</servlet-mapping>

即 jsp servlet 处理 *.jsp、*.jspx 扩展名。

因此，考虑到这一点，一个潜在的解决方法是添加 .html 以供 jsp servlet 处理，如以下链接所示：

Using .html files as JSPs

或者更好的是，将扩展名保留为 .jsp 并使用 .html 作为控制器模式？

I was also facing the same issue and tried various solutions to load the AngularJS html file using Spring configuration. After applying below steps it got resolved.

Step-1 in server's web.xml commemt these two lines

<!--     <mime-mapping>
        <extension>htm</extension>
        <mime-type>text/html</mime-type>
    </mime-mapping>--> 
<!--     <mime-mapping>
        <extension>html</extension>
        <mime-type>text/html</mime-type>
    </mime-mapping>
 -->

Step-2 enter following code in application's web xml

  <servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>*.htm</url-pattern>
</servlet-mapping>


Step-3

create a static controller class 

@Controller 
public class StatisController {
     @RequestMapping("/landingPage") 
    public String getIndexPage() { 
    return "CompanyInfo"; 

    }

}
Step-4 in the Spring configuration file change the suffix to .htm
        <property name="suffix">
            <value>.htm</value>
        </property>

Step-5
Rename page as .htm file and store it in WEB-INF and build/start the server 

localhost:8080/.../landingPage
