Springmvc上传文件限制大小,异常处理返回报错信息后,eclipse控制台还报错

1、web.xml配置:

上传文件超过限制大小,异常处理后页面返回了提示信息“上传文件太大,不能超过10k”,但是为啥eclipse的控制台还是有报错呢?

4个回答

我也是,在springmvc中配置了,为什么不能捕获异常,请问楼主解决了吗?

我也遇到这个问题了 ,在springmvc中配置了,就无法铺货异常了,请问有好的解决办法吗?

tomcat会出现这个问题,使用jetty不会有问题

今天也碰到一样的问题了,有什么办法解决吗

SpringMVC跨服务器上传文件,上传至文件服务器时报404错误
这是服务器端的代码 ``` @RequestMapping("/fileupload") public String upload(MultipartFile upload) throws IOException { System.out.println("SpringMVC跨服务器方式的文件上传..."); // 定义图片服务器的请求路径 String path = "http://localhost:9090/secondly_war_exploded/uploads/"; // 获取到上传文件的名称 String filename = upload.getOriginalFilename(); // 向图片服务器上传文件 // 创建客户端对象 Client client = Client.create(); // 连接图片服务器 WebResource webResource = client.resource(path+filename); // 上传文件 webResource.put(upload.getBytes()); return "success"; } ``` 这是报错的信息: ![图片说明](https://img-ask.csdn.net/upload/201910/05/1570271504_300400.png) 报错的核心信息是上传到图片服务器的时候404错误。 起初我以为是我的路径写的有问题或者服务器没开,然后我将路径直接粘贴到地址栏上,并没有任何问题: ![图片说明](https://img-ask.csdn.net/upload/201910/05/1570271649_380764.png) 本人在网上找了许久,也不见符合的相关答案

SpringMVC如何处理controller的各种返回类型
本人小白,求教一下各位大神,springMVC的controller的返回值都可以是什么类型? 然后springMVC对于各种返回类型是怎么处理的。 比如,我知道,如果controller返回string类型的值,那么springMVC会根据视图解析器拼接得到url,从而知道目标视图。 那么,当controlloer返回Map类型、void类型、ModelAndView(有些ModelAndView设置了viewName,有些又没设置),对于这些类型,springMVC框架都是如何处理。
为什么我们的SpringMVC项目的文件上传大小上限是500MB?
SpringMVC项目文件上传大小上限配置如下: ``` <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"/> <property name="fileItemFactory.sizeThreshold" value="0"></property> </bean> ``` 为什么这样的配置,该项目的上传大小上限却是500MB?是有其他的配置方式吗?我现在需要把上限提高到1.5G左右,请问应该怎么做,服务器那里需要有什么配置吗? 求各位大神们不吝赐教,万分感谢…
用springMVC框架做文件上传时遇到问题
我是基于red5服务器。来用springMVC框架做文件上传。在上传文件时遇到错误。 @RequestMapping(value = "/upload.do",method = RequestMethod.POST) public String upload(HttpServletRequest request, HttpServletResponse response, String string) { System.out.println("==================run in import"); System.out.println("--------------" + request.getParameter("upload")); // 创建一个通用的多部分解析器. CommonsMultipartResolver commonsMultipartResolver = new CommonsMultipartResolver( request.getSession().getServletContext()); // 设置编码 commonsMultipartResolver.setDefaultEncoding("utf-8"); System.out.println("++++++commonsMultipartResolver.isMultipart(request) : " + commonsMultipartResolver.isMultipart(request)); // 判断是否有文件上传 if (commonsMultipartResolver.isMultipart(request)) { MultipartHttpServletRequest multipartRequest = commonsMultipartResolver .resolveMultipart(request); Iterator<String> iter = multipartRequest.getFileNames(); System.out.println("+++++++++++iter = "+iter.toString()); // iter里面没有值 while (iter.hasNext()) { MultipartFile file = multipartRequest.getFile((String) iter.next()); if (file != null) { File localFile = new File("/WEB-INF/upload" + file.getOriginalFilename()); try { // file.transferTo(localFile); System.out.println("=======1111111111111===="); file.transferTo(localFile); System.out.println("====222222222222222======="); } catch (IllegalStateException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } // 批量上传 // Map<String, MultipartFile> fileMap = request.getFileMap(); // for(Entry<String, MultipartFile> entry : fileMap.entrySet()){ // MultipartFile file = entry.getValue(); // try { // file.transferTo(new File("/WEB-INF/upload" + // file.getOriginalFilename())); // } catch(IllegalStateException e){ // e.printStackTrace(); // }catch (Exception e) { // // TODO: handle exception // e.printStackTrace(); // } // } return "up"; } } 上传文件后,在我指定的地方没有找到文件。测试发现 if (commonsMultipartResolver.isMultipart(request)) 这个地方获得的是false,我这个action没有接收到上传的文件,但是通过System.out.println("--------------" + request.getParameter("upload"));获取到了我上传文件的文件名。 通过上网查找,我在配置文件中配置了MultipartResolver处理器 <!-- SpringMVC上传文件时,需要配置MultipartResolver处理器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 指定所上传文件的总大小不能超过200KB。注意maxUploadSize属性的限制不是针对单个文件,而是所有文件的容量之和 --> <property name="maxUploadSize" value="200000"/> </bean> <!-- SpringMVC在超出上传文件限制时,会抛出org.springframework.web.multipart.MaxUploadSizeExceededException --> <!-- 该异常是SpringMVC在检查上传的文件信息时抛出来的,而且此时还没有进入到Controller方法中 --> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="exceptionMappings"> <props> <!-- 遇到MaxUploadSizeExceededException异常时,自动跳转到/WEB-INF/jsp/error_fileupload.jsp页面 --> <prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">error_fileupload</prop> </props> </property> </bean> 如果我在代码最上面写 MultipartHttpServletRequest rrr = (MultipartHttpServletRequest) request; 他就会报转化错误 java.lang.ClassCastException: org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest 不知道现在是什么问题,求解啊!
springmvc统一异常处理
我最近在做异常统一处理,按照网上配置,但是报出异常也能捕捉到异常,但是就是跳转不到配合过的异常页面。 在项目中点击请求一个url,报出异常不跳转错误页面,但是把请求的url单独拿到浏览器上请求可以跳转到错误页面,请问各位大神有没有知道是什么原因的? 我的配置如下: ![图片说明](https://img-ask.csdn.net/upload/201802/28/1519789622_249548.png) 在项目页面上点击触发异常 ![图片说明](https://img-ask.csdn.net/upload/201802/28/1519790045_468962.png) ![图片说明](https://img-ask.csdn.net/upload/201802/28/1519790055_98719.png) 但是页面没有反应,没有跳转到异常页面,但是将url单独拿到浏览器请求会转发到异常页面
springMvc 返回json数据报错!
环境:springMvc5.1.8 jackson-databind2.9.9 ``` @Controller public class EmployeeController { @Autowired private EmployeeService employeeService; @RequestMapping(value = "/emps") @ResponseBody public List<Employee> findUser(@RequestParam(defaultValue = "1", name = "pageNum") Integer pageNum){ List<Employee> empsList = employeeService.selectAllEmployee(); return empsList; } } ``` 当我发送请求时报错: No

class="org.springframework.http.converter.StringHttpMessageConverter"/> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/> </mvc:message-converters>
