如何将弹簧控制器映射到扩展名为.jsp的URL？ [英] How can I map a spring controller to a url with .jsp extension?

问题描述

我们正在将仅限jsp的应用程序迁移到Spring-MVC。由于各种原因，我们无法更改当前页面的扩展名。 （对login.jsp的调用需要由将使用jsp文件作为视图的spring控制器处理。）

We are in the process of migrating a jsp-only application to Spring-MVC. For various reasons we can't change the extension of the current pages. (calls to login.jsp need to handled by a spring controller that will use a jsp file as view).

我们正在迭代地执行此操作，因此某些页面需要保留jsp文件（对welcome.jsp的调用不会由控制器处理）。

We are doing this iteratively, so some pages need to stay jsp files (calls to welcome.jsp won't be handled by a controller).

为此，我将DispatcherDervlet和HandlerMapping映射到* .jsp，并且以标准方式配置JstlView。

To do that I mapped both the DispatcherDervlet and the HandlerMapping to *.jsp, and configured the JstlView in the standard way.

不幸的是，如果我浏览到//login.jsp，我会收到错误消息

Unfortunately, if I browse to //login.jsp I get an error saying

<No mapping found for HTTP request with URI [/<context>/WEB-INF/jsp/login.jsp] in DispatcherServlet with name 'spring'>

如果我将.jsp更改为DispatcherServlet和HandlerMapping中的任何其他扩展名，则一切正常。

It all works if I change .jsp to any other extension in DispatcherServlet and HandlerMapping.

web.xml：

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
</servlet>

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

spring-servlet.xml：

spring-servlet.xml:

<!-- View resolver -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
    <property name="prefix" value="/WEB-INF/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>

<!-- URL Mapping -->
<bean id="publicUrlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">
        <map>
            <entry key="/login.jsp" value-ref="loginController"/>
        </map>
    </property>
</bean>

非常感谢。

UPDATE ：我刚刚验证过，如果我将.jsp文件重命名为其他（.jst）并相应地更新viewResolver，那么一切正常。显然，如果视图被解析为扩展名为.jsp的文件，则spring会尝试将视图转发给另一个控制器。

UPDATE: I just verified that if I rename my .jsp files to something else (.jst) and update the viewResolver accordingly, than it all works. Apparently if the view is resolved to a file with extension .jsp, spring tries to forward the view to another controller.

这对我有用。尝试将此添加到您的web.xml文件中：

This worked for me. Try adding this to your web.xml file:

<servlet-mapping>
    <servlet-name>jsp</servlet-name>
    <url-pattern>/WEB-INF/jsp/*</url-pattern>
</servlet-mapping>

请注意，即使链接中的信息，我也不明白为什么这有帮助。如果一些Spring专家可以匆匆解释，我很想知道。

Please note that even with the information in the link, I don't understand why this is helping. If some Spring expert could drop by and explain it, I'd love to know.

我也不能保证这可能造成潜在的安全/可靠性问题，所以使用风险自负。

I also can't guarantee that there are no potential security/reliability issues this could create, so use at your own risk.
