1 在application.properties中进行配置#文件请求大小spring.server.MaxFileSize=100MBspring.server.MaxRequestSize=200MB
maxFileSize 单个数据大小
maxRequestSize 是总数据大小
2 启动类上添加代码，并在类上加入@Configuration@Configuration@SpringBootApplicationpublic class application { public static void main(Stringwjdyj args) { application .run(application .class, args); } @Value("${spring.server.MaxFileSize}") private String MaxFileSize; @Value("${spring.server.MaxRequestSize}") private String MaxRequestSize; @Bean public MultipartConfigElement multipartConfigElement() { MultipartConfigFactory factory = new MultipartConfigFactory(); // 单个数据大小 factory.setMaxFileSize(MaxFileSize); // 总上传数据大小 factory.setMaxRequestSize(MaxRequestSize); return factory.createMultipartConfig(); }}
3 重启项目就可以了 本文网址：http://www.shaoqun.com/a/447886.html
