Springboot 文件上传超过限制处理

springboot文件上传报错

org.apache.tomcat.util.http.fileupload.FileUploadBase$FileSizeLimitExceededException: The field fileName exceeds its maximum permitted size of 1048576 bytes.

Spring Boot默认文件上传大小为2M，多文档上传中总是出现文件大小超出限度

处理

1.在application.properties文件中设置文件大小

# Single file max size
multipart.maxFileSize=50Mb
# All files max size
multipart.maxRequestSize=100Mb

2.在启动类App.class文件中配置Bean来设置文件大小

package com.source;

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

import javax.servlet.MultipartConfigElement;

@SpringBootApplication
@Configuration
public class SpringbootUploadDownloadApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootUploadDownloadApplication.class, args);
    }

    /**
     * 文件上传配置
     * @return
     */
    @Bean
    public MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        //单个文件最大
        factory.setMaxFileSize("50240KB"); //KB,MB
        /// 设置总上传数据总大小
        factory.setMaxRequestSize("1002400KB");
        return factory.createMultipartConfig();
    }
}
