您要做的是在spring servlet-context xml配置中添加此行.

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

该mvcXML命名空间是在xmlns:mvc="http://www.springframework.org/schema/mvc"

该resources标签基本上告诉Spring从申报位置服务了一个名为文件,而不是通过你的控制器栈去处理请求的声明映射.映射还可用于提供任何资源:css,js,pdf等.

您不需要多个<mvc:resources>标签,只需要一个带有通用映射的标签,例如./ resources/**和逗号分隔的位置列表,例如./ resources/css /,/ resources/js /.

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

该<resources>标签是在Spring 3.0.4中引入的,因此至少需要该版本的Spring和xsd.您可以使用

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd`

此外,正如JB Nizet所说,您应该将您的图像引用为

<img src="<c:url value='/images/top.jpg'/>"/>
