springboot上传文件解析器

@Bean(name = “multipartResolver”)
public MultipartResolver multipartResolver() {
CommonsMultipartResolver resolver = new CommonsMultipartResolver();
resolver.setDefaultEncoding(“UTF-8”);
resolver.setResolveLazily(true);// 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.setMaxInMemorySize(40960);
resolver.setMaxUploadSize(5 * 1024 * 1024 * 1024);// 上传文件大小 5G
return resolver;
