SpringMVC Required request part 'file' is not present

 

 

 

    public String testFileUpload(@RequestParam(value = "file") MultipartFile file,@RequestParam(value = "desc") String desc)
    {
        System.out.println("desc"+desc);
        System.out.println(file.getOriginalFilename());
        return "success";
    }

 

 

 SpringBoot项目中进行如下配置：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.multipart.MultipartResolver;
import org.springframework.web.multipart.commons.CommonsMultipartResolver;


@Configuration
public class MultipartResolverConfig {
    @Bean(name = "multipartResolver")
    public MultipartResolver multipartResolver(){
        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        //上传文件大小 10M 10*1024*1024
        resolver.setMaxUploadSize(10*1024*1024);
        resolver.setDefaultEncoding("UTF-8");
        return resolver;
    }
}

Controller:

 @PostMapping(value = "/import/test")
    public String importTest(
                                          @RequestParam(value = "file") MultipartFile uploadFile,
                                          HttpServletRequest request){

        return "SUCCESS";
    }

注意：参数名必须一致

HTML:

<form id="initialUploadForm" action="http://localhost:8080/import/test" enctype="multipart/form-data" method="post">
                <table align="left" width="50%" cellspacing="0" cellpadding="5"
                       border="0" class="formTable">
                    <tr>
                        <td><label class="">Add Cap File : </label></td>
                        <td><input type="file" name="file" style="width:100%;"/></td>
                    </tr>
                    <tr>
                        <td colspan="2">&nbsp;</td>
                    </tr>
                    <tr>
                        <td>&nbsp;</td>
                        <td><input class="btn btn-success" type="submit"
                                   value="Upload Data" id="btnInitialUpload"/></td>
                    </tr>
                    <tr>
                        <td colspan="2">&nbsp;</td>
                    </tr>
                </table>
</form>
