java - spring mvc中如何使用静态资源？

Question

在spring mvc中如何使用静态资源？我只想在jsp中插入一些图像。我必须在哪个地方找到我的资源？上次我曾经在 servlet-context 中添加 mvc:recources，但它显示我很少有映射错误。

我仍然有麻烦。我又提了一个问题。拜托，HALP。 https://stackoverflow.com/questions/18020129/troubles-with-static-resources-and-mvcresources

我的配置:

我的jsp:

<p>
    <small>With Spring MVC</small><img src='<c:url value="/static/img/logo.gif"/>' />

Answer 1

如果您收到 404 错误意味着请求的资源不适用，则意味着您有映射错误，在此映射之后还需要检查 controller-servlet.xml 映射。如果出现错误，请提供您的代码。

试试这个

<servlet>
<servlet-name>app</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
 </servlet>

<servlet-mapping>
<servlet-name>app</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

Controller-servlet.xml
<bean id="urlMapping" class="org.springframework.Handler.SimpleHandlerMapping">
<property name="mapping">
<props><prop key="app.do">hello</prop></props></property></bean>
