spring boot 文件上传大小配置

在启动类中，添加bean

import javax.servlet.MultipartConfigElement;
 
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;
 
@Configuration
@SpringBootApplication
public class FileProApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(FileProApplication.class, args);
    }
 
    //上传文件大小
    @Bean
    public MultipartConfigElement multipartConfigElement() {
        MultipartConfigFactory factory = new MultipartConfigFactory();
        // 文件最大
        factory.setMaxFileSize("10240KB"); // KB,MB
        /// 设置总上传数据总大小
        factory.setMaxRequestSize("102400KB");
        return factory.createMultipartConfig();
    }
 
}
