el-upload上传文件后台MultipartFile接不到的解决方案
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 UploadConfig {
//显示声明CommonsMultipartResolver为mutipartResolver
@Bean(name = "multipartResolver")
public MultipartResolver multipartResolver() {
CommonsMultipartResolver resolver = new CommonsMultipartResolver();
resolver.setDefaultEncoding("UTF-8");
//resolveLazily属性启用是为了推迟文件解析，以在在UploadAction中捕获文件大小异常
resolver.setResolveLazily(true);
resolver.setMaxInMemorySize(40960);
//上传文件大小 50M 50*1024*1024
resolver.setMaxUploadSize(50 * 1024 * 1024);
return resolver;
}
