本文介绍了所需的MultipartFile参数“文件”不存在的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用Spring Boot来测试上传功能，并且获取
'所需的MultipartFile参数'文件'不存在'
错误。以下是1）JSP，2）控制器3）配置类4）嵌入式tomcat日志。

解决方案 我发现在Spring引导中有一个MultipartAutoConfiguration问题。我禁用它，并添加@Bean在网络配置，它的工作。根据例外情况，我看到Jackson Mapper试图解析多部分内容，而不是多部分解析器本身。
以下是摘录。
@EnableAutoConfiguration（exclude = {MultipartAutoConfiguration.class}
在您的webconfig类中添加以下内容：
$ b $ public class WebConfig extends WebMvcConfigurerAdapter {
$Be $（$ $ $ $ $ $ $ $ CommonsMultipartResolver multipartResolver $）
Common CommonsMultipartResolver multipartResolver（）{
logger.info（加载多重解析器）;
CommonsMultipartResolver multipartResolver
= new CommonsMultipartResolver（）;
返回multipartResolver;
}
I am using Spring Boot to test a upload functionality, and getting'Required MultipartFile parameter 'file' is not present'error. Following are the 1) JSP, 2) Controller 3) Config Class 4) embedded tomcat log.
JSP page
----------------------------------------------------------------------------
<!DOCTYPE html>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

</tr>
</table>
</form>
</body>
</html>
2. Controller:
@RequestMapping(value = "/uploadObject", method = RequestMethod.POST)
@Override
public String upload(@RequestParam("file") MultipartFile file,
@RequestParam("bucketName") String bucketName,
Map<String, Object> model) {
LOG.info("Object name parameter is " + file.getOriginalFilename());
LOG.info("Bucket name parameter is " + bucketName);
....
}

}
@Bean

MultiPartConfigFactory factory = new MultiPartConfigFactory();
factory.setMaxFileSize("1024KB");
factory.setMaxRequestSize("1024KB");
return factory.createMultipartConfig();
}

解决方案 I figured out that there is an issue with the MultipartAutoConfiguration within spring boot. I disabled it and added @Bean in the web config and it worked. Based on the exception I saw that the Jackson Mapper was trying to resolve the multipart content instead of the multipart resolver itself.
Here is the snippet.
@EnableAutoConfiguration(exclude={MultipartAutoConfiguration.class}
Add the following in your webconfig class
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
logger.info("Loading the multipart resolver");
CommonsMultipartResolver multipartResolver
= new CommonsMultipartResolver();
return multipartResolver;
}
这篇关于所需的MultipartFile参数“文件”不存在的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！

解决方案 我发现在Spring引导中有一个MultipartAutoConfiguration问题。我禁用它，并添加@Bean在网络配置，它的工作。根据例外情况，我看到Jackson Mapper试图解析多部分内容，而不是多部分解析器本身。
以下是摘录。
@EnableAutoConfiguration（exclude = {MultipartAutoConfiguration.class}
在您的webconfig类中添加以下内容：
$ b $ public class WebConfig extends WebMvcConfigurerAdapter {
$Be $（$ $ $ $ $ $ $ $ CommonsMultipartResolver multipartResolver $）
Common CommonsMultipartResolver multipartResolver（）{
logger.info（加载多重解析器）;
CommonsMultipartResolver multipartResolver
= new CommonsMultipartResolver（）;
返回multipartResolver;
}
I am using Spring Boot to test a upload functionality, and getting'Required MultipartFile parameter 'file' is not present'error. Following are the 1) JSP, 2) Controller 3) Config Class 4) embedded tomcat log.
JSP page

2. Controller:

@Override

@RequestParam("bucketName") String bucketName,

解决方案 I figured out that there is an issue with the MultipartAutoConfiguration within spring boot. I disabled it and added @Bean in the web config and it worked. Based on the exception I saw that the Jackson Mapper was trying to resolve the multipart content instead of the multipart resolver itself.
Here is the snippet.
@EnableAutoConfiguration(exclude={MultipartAutoConfiguration.class}
Add the following in your webconfig class
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean(name = "multipartResolver")
public CommonsMultipartResolver multipartResolver() {
logger.info("Loading the multipart resolver");
CommonsMultipartResolver multipartResolver
= new CommonsMultipartResolver();
return multipartResolver;
}
这篇关于所需的MultipartFile参数“文件”不存在的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
