Spring Boot:The field file exceeds its maximum permitted size of 1048576 bytes

錯誤信息:The field file exceeds its maximum permitted size of 1048576 bytes
原因是因為SpringBoot內嵌tomcat默認所能上傳的文件大小為1M,超出這個就會報錯。

解決辦法:

1.修改application.yml配置文件

spring:
  http:
    multipart:
      enabled: true
      max-file-size: 30MB
      max-request-size: 30MB

2.編寫配置類

package com.blog.springboot.config;

import javax.servlet.MultipartConfigElement;

import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MulterFile {
    /**  
     * 文件上傳配置  
     * @return  
     */  
    @Bean  
    public MultipartConfigElement multipartConfigElement() {  
        MultipartConfigFactory factory = new MultipartConfigFactory();  
        //文件最大  
        factory.setMaxFileSize("30960KB"); //KB,MB  
        /// 設置總上傳數據總大小  
        factory.setMaxRequestSize("309600KB");  
        return factory.createMultipartConfig();  
    }
}
