springboot 上传图片到服务器磁盘，数据库地址映射磁盘地址

1、yml文件

jingle:systemName: XXXXofficeName: XXXXversion: 1.0copyrightYear: 2019profile: d://jingle/staticAccessPath: /profile/**staticAccess: /profilefileExt: .png|.jpg|.jpeg|.gif|.bmp|.rar|.zip|.doc|.docx|.xls|.xlsx|.ppt|.pptx|.pdf|.txt

2 、配置类

/*** 通用配置* */
@Configuration
public class ResourcesConfig extends WebMvcConfigurerAdapter
{@Value("${jingle.staticAccessPath}")private String staticAccessPath;/*** 首页地址*/@Value("${shiro.user.indexUrl}")private String indexUrl;/*** 默认首页的设置，当输入域名是可以自动跳转到默认指定的网页*/@Overridepublic void addViewControllers(ViewControllerRegistry registry){registry.addViewController("/").setViewName("forward:" + indexUrl);registry.setOrder(Ordered.HIGHEST_PRECEDENCE);super.addViewControllers(registry);}@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry){registry.addResourceHandler(staticAccessPath).addResourceLocations("file:" + JingleConfig.getProfile());}
}

3、config

/*** 读取项目相关配置* * @author jingle*/
@Component
@ConfigurationProperties(prefix = "jingle")
public class JingleConfig
{/** 机构名称 */private String officeName;/** 项目名称 */private String systemName;/** 版本 */private String version;/** 版权年份 */private String copyrightYear;public static String userId = "70120008";public static String  webserviceUrl;public static String privateKey;private Integer queryNum;/** 上传路径 */private static String profile;private static String staticAccessPath;private static String staticAccess;public static String exportExcelPath="d:/export/excel/";public static String  fileExt=".png|.jpg|.jpeg|.gif|.bmp|.rar|.zip|.doc|.docx|.xls|.xlsx|.ppt|.pptx|.pdf|.txt";private static String hngpUrl;private static Integer hngpUsername;private static String hngpPassword;private static String serviceUrl;private static String bankName;private static String bankNo;private static String appId;private static String merchantPrivateKey;private static String alipayPublicKey;public static String getAppId() {return appId;}public static void setAppId(String appId) {JingleConfig.appId = appId;}public static String getMerchantPrivateKey() {return merchantPrivateKey;}public static void setMerchantPrivateKey(String merchantPrivateKey) {JingleConfig.merchantPrivateKey = merchantPrivateKey;}public static String getAlipayPublicKey() {return alipayPublicKey;}public static void setAlipayPublicKey(String alipayPublicKey) {JingleConfig.alipayPublicKey = alipayPublicKey;}public static String getBankName() {return bankName;}public static void setBankName(String bankName) {JingleConfig.bankName = bankName;}public static String getBankNo() {return bankNo;}public static void setBankNo(String bankNo) {JingleConfig.bankNo = bankNo;}public static String getHngpUrl() {return hngpUrl;}public static void setHngpUrl(String hngpUrl) {JingleConfig.hngpUrl = hngpUrl;}public static Integer getHngpUsername() {return hngpUsername;}public static void setHngpUsername(Integer hngpUsername) {JingleConfig.hngpUsername = hngpUsername;}public static String getHngpPassword() {return hngpPassword;}public static void setHngpPassword(String hngpPassword)   {JingleConfig.hngpPassword = hngpPassword;}public static String getServiceUrl() {return serviceUrl;}public static void setServiceUrl(String serviceUrl) {JingleConfig.serviceUrl = serviceUrl;}public String getSystemName() {return systemName;}public void setSystemName(String systemName) {this.systemName = systemName;}public String getOfficeName() {return officeName;}public void setOfficeName(String officeName) {this.officeName = officeName;}public String getVersion(){return version;}public void setVersion(String version){this.version = version;}public String getCopyrightYear(){return copyrightYear;}public void setCopyrightYear(String copyrightYear){this.copyrightYear = copyrightYear;}public static String getUserId() {return userId;}public static void setUserId(String userId) {JingleConfig.userId = userId;}public static String getWebserviceUrl() {return webserviceUrl;}public static void setWebserviceUrl(String webserviceUrl) {JingleConfig.webserviceUrl = webserviceUrl;}public Integer getQueryNum() {return queryNum;}public void setQueryNum(Integer queryNum) {this.queryNum = queryNum;}public static String getProfile(){return profile;}public static void setProfile(String profile){JingleConfig.profile = profile;}public static String getPrivateKey() {return privateKey;}public static void setPrivateKey(String privateKey) {JingleConfig.privateKey = privateKey;}public static String getExportExcelPath() {return exportExcelPath;}public static void setExportExcelPath(String exportExcelPath) {JingleConfig.exportExcelPath = exportExcelPath;}public static String getStaticAccessPath() {return staticAccessPath;}public static void setStaticAccessPath(String staticAccessPath) {JingleConfig.staticAccessPath = staticAccessPath;}public static String getStaticAccess() {return staticAccess;}public static void setStaticAccess(String staticAccess) {JingleConfig.staticAccess = staticAccess;}public static String getFileExt() {return fileExt;}public static void setFileExt(String fileExt) {JingleConfig.fileExt = fileExt;}}

4、controller

public String ueditorUpload(@RequestParam(value = "upfile", required = false) MultipartFile file, HttpServletResponse response, HttpServletRequest request) throws Exception {Map<String, Object> imgMap = new HashMap<String, Object>();try {String ext = FileUtil.extName(file.getOriginalFilename());imgMap.put("state", "FAILED");// if(JingleConfig.fileExt.contains(ext)){// String subFolder = "uploadfile" ;SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMdd");String dateString = "/" + simpleDateFormat.format(new Date());String path = FileUploadUtils.upload(ext + dateString, file);imgMap.put("url", path);imgMap.put("state", "SUCCESS");imgMap.put("title", file.getOriginalFilename());imgMap.put("original", file.getOriginalFilename());/** } else { imgMap.put("msg", "不支持上传"+ext+"类型文件"); }*/} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();imgMap.put("msg", "服务器异常" + e.getMessage());}return JSON.toJSONString(imgMap);}
