错误返回:
Required request part 'file' is not present
请检查你是否引入了这个jar包
自带了upload files的配置
1.如果没有
上传文件时需要引入并在webMvc配置
<!-- fileupload -->
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.3</version>
</dependency>
没有上面jar包时需要引入
@Bean
public MultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(environment.getProperty("file.upload.max.size", Long.class, 104857600L));
return multipartResolver;
}
