解决Expected MultipartHttpServletRequest: is a MultipartResolver configured

问题描述:springmvc后台写文件上传接受功能时,使用mutipartfile会报错,提示MultipartResolver没有声明

解决办法:

1.导入文件上传依赖

2.配置bean文件声明MultipartResolver即可

(1).有配置文件的:

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

(2).没有配置文件的:

在配置了basePackages的java文件中加入

@Bean(name="multipartResolver")

public MultipartResolver getMultipartResolver(){

CommonsMultipartResolver multipartResolver =new CommonsMultipartResolver();

multipartResolver.setMaxUploadSizePerFile(100000000);//100M

multipartResolver.setDefaultEncoding("UTF-8");

multipartResolver.setResolveLazily(true);

return multipartResolver;

}
