springboot上传文件过大的500异常解决
修改appliaction.properties
#单个文件最大20m spring.servlet.multipart.max-file-size=20MB #一次请求最大100M spring.servlet.multipart.max-request-size=100MB
如果配置文件为appliaction.yml的这样配置文件：
spring: servlet: multipart: maxFileSize:20MB maxRequestSize:100MB
500代码异常，在启动类的里追加
/**
*文件上传配置
*
*@return
*/
@Bean
publicMultipartConfigElementmultipartConfigElement(){
/*
springBoot1.0+推荐这种写法
MultipartConfigFactoryfactory=newMultipartConfigFactory();
//单个文件最大
factory.setMaxFileSize("20480KB");//KB,MB
factory.setMaxFileSize("20480KB");
///设置总上传数据总大小
factory.setMaxRequestSize("102400KB");
returnfactory.createMultipartConfig();
*/
//springBoot2.0+推荐这种写法，
MultipartConfigFactoryfactory=newMultipartConfigFactory();
//文件最大10M,DataUnit提供5中类型B,KB,MB,GB,TB
factory.setMaxFileSize(DataSize.of(10,DataUnit.MEGABYTES));
///设置总上传数据总大小10M
factory.setMaxRequestSize(DataSize.of(100,DataUnit.MEGABYTES));
returnfactory.createMultipartConfig();
}
这是我的启动类：

corsConfiguration.addAllowedOrigin("*");//1允许任何域名使用

returncorsConfiguration;
}
@Bean
publicCorsFiltercorsFilter(){
UrlBasedCorsConfigurationSourcesource=newUrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**",buildConfig());//4
returnnewCorsFilter(source);
}
