java - Servlet 映射与 mvc 资源 spring 相关的问题

Question

我对 mvc:resources 有疑问

我的main-servlet.xml

    **
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="multipartResolver"
        class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="50000000" />
    </bean>

    <mvc:resources mapping="/images/**" location="/images/" />
    <mvc:resources mapping="/css/**" location="/css/" />
    **

当我评论 mvc:resources 行时，一切(其他)都开始神奇地工作。但是当我取消注释这些行时，只有资源有效。编译时，日志显示仅映射了 css/** 和 images/** ，没有其他映射。

Web.xml 文件:

<servlet-mapping>
    <servlet-name>main</servlet-name>
    <url-pattern>/css/**</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>main</servlet-name>
    <url-pattern>/images/**</url-pattern>
</servlet-mapping>
     <servlet-mapping>
    <servlet-name>main</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

我尝试放置 2 个调度程序 servlet，但这也不起作用。另一个 servlet 被读取并被映射，但请求默认到主 servlet。

从 web.xml 注释/css/** 和/images/** 后的编译日志:

    **

Answer 1

请注意，您的任何 Controller 都不会在您当前的设置中注册。您需要添加

<mvc:annotation-driven />

到您的上下文，以便 Spring 使用 DispatcherServlet 注册它们。

您的main DispatcherServlet也应该简单地映射到

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

其他都是多余的。
