spring boot上传附件报错：org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException【转载+整理】

问题

spring boot + spring cloud，上传附件时遇到如下错误：

org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (11963927) exceeds the configured maximum (10485760)

错误信息表示上传附件报超出自带tomacat限制大小（默认1M）\

解决

在配置文件（application.properties或是application.yml）加入如下代码

1 2	spring.http.multipart.maxFileSize = 10Mb spring.http.multipart.maxRequestSize=100Mb

把如下代码放在启动类上，并在类上加入@Configuration

/**
   * 文件上传配置
   * 
   * @return
   */
  @Bean
  public MultipartConfigElement multipartConfigElement() {
      MultipartConfigFactory factory = new MultipartConfigFactory();
      //  单个数据大小
      factory.setMaxFileSize("10240KB"); // KB,MB
      /// 总上传数据大小
      factory.setMaxRequestSize("102400KB");
      return factory.createMultipartConfig();
  }

我这里选择只修改配置参数，就修复了问题。
