spring boot上传附件报错：org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException

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)

项目使用的是Spring Boot + Spring Cloud，上传附件报超出自带tomacat限制大小（默认1M）

解决办法：

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

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

maxFileSize 单个数据大小

maxRequestSize 是总数据大小

（2）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();
    }
