SpringMVC上传遇到的问题

记录日常

pom.xml配置

<dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.1</version>
    </dependency>
    <dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.4</version>
    </dependency>

springmvb.xml配置

<context:component-scan base-package="com.mvc.controller"/>
 <mvc:annotation-driven/>
  <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
 </bean>

service接收文件

@Controller
@RequestMapping("/file")
public class FileController {
	@RequestMapping("upload.do")
    public String upload(@RequestParam("myFile") MultipartFile myFile, HttpServletRequest request) throws IOException {
        String originalFilename = myFile.getOriginalFilename();
        String fileName=UUID.randomUUID().toString().replace("-","")+originalFilename.substring(originalFilename.lastIndexOf("."));
        String realPath = request.getServletContext().getRealPath("/uploadFile")+"/";
        myFile.transferTo(new File(realPath+fileName));
        System.out.println("上传成功");
        return "OK";
    }
}

遇到的问题

Request processing failed; nested exception is org.springframework.web.multipart.MultipartException

解决方法
在springmvc配置中

  <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>

id不能缺，设定为multipartResolver
