春季静态资源映射
自从我开始使用Spring之后，就出现了这个错误，我无法处理静态内容
我的dispatcher-servlet配置

<img src="<c:url value="/resources/captcha/13.PNG"/>"/>但是我的日志显示如下：

01:19:10,805调试SimpleUrlHandlerMapping:124 - and /resources/captcha/35.png到带有处理程序org.springframework.web.servlet.resource.DefaultServletHttpRequestHandler@eea824和一个拦截器的HandlerExecutionChain
01:19:10,805调试DispatcherServlet:912 - /project/resources/captcha/35.png的最后修改值为：-1
01:19:10,805调试DispatcherServlet :999-Null ModelAndView返回给DispatcherServlet，名为“dispatcher”：假设HandlerAdapter完成了请求处理
01:19:10,806调试DispatcherServlet:966 -成功完成请求
我是不是错过了更多的配置？
谢谢

当您尝试访问/resources/captcha/13.PNG时
它通过以下方式映射到默认servlet：
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.PNG</url-pattern>
</servlet-mapping>它没有映射到/resources/captcha/，因为资源查找具有http://localhost:8080/captcha/*类型的路径，而不是具有http://localhost:8080/resources/captcha/*类型的路径，因此要处理此类请求，需要有一个视图解析器来响应/resources/*模式。
就像这样
@RequestMapping(path = '/resources/*')
public Object handler(){...}我的猜测是，您希望将PNG映像呈现为静态资源，您可能应该拥有<img src="<c:url value="/resources/captcha/13.PNG"/>"/>。
注:我不知道我的建议是否有效。我的回答完全是基于我的记忆，没有测试你提到的任何情况。
