  回答 5 已采纳 HttpServletRequest request = ServletActionContext.getRequest(); String UserStr = HttpServletRequestUtil.getString(request,"Userstr"); System.out.println("UserStr:"+UserStr); MultipartHttpServletRequest multipartRequest = null; MultipartFile profileImg = null; CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext()); System.out.println("multipartResolver.isMultipart(request):"+multipartResolver.isMultipart(request)); if (multipartResolver.isMultipart(request)) { multipartRequest = multipartResolver.resolveMultipart(request); profileImg = (MultipartFile) multipartRequest.getFile("fileupload"); } HttpServletRequest request = ServletActionContext.getRequest(); String UserStr = HttpServletRequestUtil.getString(request,"Userstr"); System.out.println("UserStr:"+UserStr); MultipartHttpServletRequest multipartRequest = null; MultipartFile profileImg = null; CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext()); System.out.println("multipartResolver.isMultipart(request):"+multipartResolver. 问题： multipartRequest.getFile("fileupload")为null 有时form表单中的Userstr也为null

  回答 4 已采纳 [code="java"] public String upload2(MultipartHttpServletRequest request, @RequestParam("name") String name){ List files = (List) request.getFile("myfiles"); } //修改成如下方法，还是报同样下面的错误： public String upload2(MultipartHttpServletRequest request, @RequestParam("name") String name, // 页面上的控件值 @RequestParam MultipartFile[] myfiles) { List files = Arrays.asList(myfiles); } // jsp页面，传一个myfiles，单个文件是可以通过的， [/code] [code="html"] [/code] 报错：[code="java"] org.springframework.web.multipart.MultipartException: Multiple files for field name [myfiles] found - not supported by MultipartResolver at org.springframework.web.multipart.commons.CommonsFileUploadSupport.parseFileItems(CommonsFileUploadSupport.java:254) at org.springframework.web.multipart.commons.CommonsMultipartResolver.parseRequest(CommonsMultipartResolver.java:166) at org.springframework.web.multipart.commons.CommonsMultipartResolver.resolveMultipart(CommonsMultipartResolver.java:149) at org.springframework.web.servlet.DispatcherServlet.checkMultipart(DispatcherServlet.java:1015) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:851) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:807) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:511) at javax.servlet.http.HttpServlet.service(HttpServlet.java:643) at javax.servlet.http.HttpServlet.service(HttpServlet.java:723) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:96) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:619) [/code]

  weixin_39668408的博客 最近我们前台架构的契约发生一次漏洞，造成契约脑裂。由于开发时间比较紧张，没有太多时间在协议上下功夫，在联调过程中造成不必要的弯路。Content-Type是什么？在RESTful接口的每个请求和响应中都会有Content-Type属性，存放在header头中。若是POST请求时必须要指定请求头Content-Type属性，一般我们使用application/x-www-form-urlencode...
