springboot 文件上傳超出大锌还蟆：MultipartFile file

異常信息如下：

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is 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 (76559398) exceeds the configured maximum (52428800)] with root cause

解決方案：
使用這種發(fā)現(xiàn)不生效：

uploadFile 修改上傳文件的大小限制

spring.http.multipart.max-file-size=100MB

spring.servlet.multipart.max-file-size=100MB
spring.servlet.multipart.max-request-size=100MB

生效方案如下：完美解決
/**

• 修改上傳文件的大小限制
• @author heng
  */
  @Configuration
  public class MultipartConfig {
  @Bean
  public MultipartConfigElement multipartConfigElement() {
  MultipartConfigFactory factory = new MultipartConfigFactory();
  factory.setMaxRequestSize("200Mb");
  factory.setMaxFileSize("200Mb");
  return factory.createMultipartConfig();
  }
  }
