欢迎文件在春季不适用于 html 文件

Question

提问by Sarika.S

I have given my welcome file in web.xml But when running the application, it is showing 404 error on http://172.16.2.16:8080/sampletest/

我在 web.xml 中提供了我的欢迎文件但是在运行应用程序时，它显示 404 错误 http://172.16.2.16:8080/sampletest/

It is a spring application.

这是一个弹簧应用程序。

web.xml

网页.xml

    <display-name>sampletest</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

    <!-- Spring MVC -->

        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

I am using eclipse luna, java 8, tomcat 8 and maven framework. index.html file is directly under webapp folder and web.xml is under webapp/WEB-INF folder. If I use index.jsp instead of index.html, it is working. Then welcome page will load using http://172.16.2.16:8080/sampletest/

我正在使用 eclipse luna、java 8、tomcat 8 和 maven 框架。index.html 文件直接位于 webapp 文件夹下，而 web.xml 位于 webapp/WEB-INF 文件夹下。 如果我使用 index.jsp 而不是 index.html，它就可以工作。然后欢迎页面将加载使用http://172.16.2.16:8080/sampletest/

The issue is only with welcome file. Otherwise spring configuration is working. http://localhost:8080/sampletest/test/will load the data from database.

问题仅与欢迎文件有关。否则弹簧配置正在工作。 http://localhost:8080/sampletest/test/将从数据库加载数据。

Try adding <mvc:default-servlet-handler/>in your dispatcher-servlet.xml.

尝试添加<mvc:default-servlet-handler/>您的 dispatcher-servlet.xml。

See herefor details.

回答by Santhosh

You have mapped all your incoming requests to the dispatcherhere,

您已将所有传入请求映射到dispatcher此处，

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

So all your URLrequests for the application goes inside the dispatcher as '/' maps all incoming requests . check for the stacktraces in your application server log

因此，您URL对应用程序的所有请求都会进入调度程序，因为“/”映射所有传入请求。检查应用程序服务器日志中的堆栈跟踪

update:

更新：

You get the below warning because there are no handler for the '/' pattern,

您收到以下警告，因为“/”模式没有处理程序，

WARNING: No mapping found for HTTP request with URI [/AccelFlow/] in DispatcherServlet with name 'dispatcher'

警告：在名称为“dispatcher”的 DispatcherServlet 中找不到带有 URI [/AccelFlow/] 的 HTTP 请求的映射

You can do either of below options ,

您可以执行以下任一选项，

Map a url with '/' to the controller
Add a specific URL pattern to the spring dispatcher such as .htm or .doas you wish

将带有“/”的 url 映射到控制器
将特定的 URL 模式添加到 spring 调度程序，.htm or .do如您所愿

Modify your web.xml,

修改你的web.xml，

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

And in your controller,

在你的控制器中，

@RequestMapping(value = "/test.htm", method = RequestMethod.GET)
public @ResponseBody Response display() throws Exception {
    accelFlowFacade.disaply();
    Response res = new Response();
    return res;
}

Answer 3

回答by Saifulcse01

At the startup by default all incoming requests are mapping to '/' pattern as you write in the web.xml:

默认情况下，在启动时，所有传入请求都映射到您在 web.xml 中写入的“/”模式：

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

update:

更新：

Try to map a Controller method for the default view:

@RequestMapping(value = "/", method = GET)
public String welcome() {
    return "index";
}

Add viewresolver to dispather-servlet.xml:

<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/"
      p:suffix=".jsp" />

Remove welcome file from the web.xml as automatically spring will search for index page by default:
```
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
```

尝试为默认视图映射 Controller 方法：

@RequestMapping(value = "/", method = GET)
public String welcome() {
    return "index";
}

将 viewresolver 添加到 dispather-servlet.xml：

<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/"
      p:suffix=".jsp" />

从 web.xml 中删除欢迎文件，因为默认情况下 spring 将自动搜索索引页面：
```
<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
```

Welcome file can be access using following changes.

可以使用以下更改访问欢迎文件。

change 1. add resource path in dispatcher as following :

更改 1. 在调度程序中添加资源路径如下：

      <mvc:resources mapping="/" location="/index.html" />

change 2. add controller handler like following :

更改 2. 添加控制器处理程序，如下所示：

     @Controller
      public class RestController {

     @RequestMapping(value = "/", method = RequestMethod.GET)
      public String welcome() {
            return "index.html";
      }

     }

changes 3: index.html file should be in WebContent folder in project.

变化 3：index.html 文件应该在项目的 WebContent 文件夹中。

Note : If you are not able to add mvc bean in dispatcher servlet file then add

注意：如果您无法在调度程序 servlet 文件中添加 mvc bean，则添加

  xmlns:mvc="http://www.springframework.org/schema/mvc

in dispatcher servlet config file.

在调度程序 servlet 配置文件中。

using <mvc:resources mapping="/" location="/index.html" />is goods for static pages , however changing it to

using <mvc:resources mapping="/" location="/index.html" />is good for static pages ，但是将其更改为

@RequestMapping(value = "/", method = RequestMethod.GET) public String welcome() { return "index.html"; }

is not good design as all model in other controllers may point back to index page, instead use

不是好的设计，因为其他控制器中的所有模型都可能指向索引页面，而是使用

<mvc:resources mapping="/" location="/redfresh.html"  />

and make refresh page such

并制作刷新页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8"/>
    <meta http-equiv="refresh" content="0;URL='/index'" />
</head>
<body>
</body>
</html>

and point in controller to index such:

并在控制器中指向索引：

@Controller
public class indexPageController {

 @RequestMapping(value = "/index", method = RequestMethod.GET, produces = "text/html")
    public String index() {       
        return "index";
    }
}
