文件上传以及配置跨域问题

1、文件上传代码

@Transactional(rollbackFor=Exception.class) public String uploadFile(MultipartFile file,FileVo fileVo) throws Exception{ //按日期目录存放 String trsfilename = DateTimeUtil.getDateTime("yyyyMMddHHmmssSSS"); String fileName = file.getOriginalFilename(); String fileSavePath = savePath + "/" + trsfilename.substring(0, 4) + "/" + trsfilename.substring(4, 6) + "/" + trsfilename.substring(6, 8); //判断目录是否存在，不存在则创建目录 File dir = new File(fileSavePath); if (!dir.exists()) { dir.mkdirs(); } File dest = new File(fileSavePath +"/"+ fileName); file.transferTo(dest); logger.info("上传成功"); return "上传成功"; }

2、允许跨域请求的Filter配置

package com.njwd.costconfig.aop; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.UrlBasedCorsConfigurationSource; import org.springframework.web.filter.CorsFilter; @Configuration public class Corsconfig { private CorsConfiguration buildConfig() { CorsConfiguration corsConfiguration = new CorsConfiguration(); corsConfiguration.setAllowCredentials(true); corsConfiguration.addAllowedOrigin("*"); corsConfiguration.addAllowedHeader("*"); corsConfiguration.addAllowedMethod("*"); return corsConfiguration; } @Bean public CorsFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", buildConfig()); return new CorsFilter(source); } }
