解决方案
我直接放源码了。
原理就是：我虽然调用的是虚拟目录，但是会映射到对应路径的实际
第一步：（在tomcat的 server.xml中创建一个虚拟目录）
虚拟目录创建方式：
<Context docBase="E:\liujinhua\img" path="/statics/uploadfiles" reloadable="true"/>
docBase：文件实际存储路径
path：Tomcat中虚拟路径
<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
Note: The pattern used is equivalent to using pattern="common" -->
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t "%r" %s %b" prefix="localhost_access_log" suffix=".txt"/>
<!-- <Context docBase="E:/青鸟学习/SSM/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/" path="/smbms-liujinhua2/statics/uploadfiles/" reloadable="true" source="org.eclipse.jst.jee.server:smbms-liujinhua2"/> -->
<Context docBase="E:\liujinhua\img" path="/statics/uploadfiles" reloadable="true"/>
<Context docBase="smbms-liujinhua2" path="/smbms-liujinhua" reloadable="true" source="org.eclipse.jst.jee.server:smbms-liujinhua2"/></Host>
第二步：（改写存进数据库的路径。）
/**

@RequestMapping(value = "/addProviderSava.html", method = RequestMethod.POST)
public String addProviderSava(Provider provider, HttpSession session, HttpServletRequest request,
@RequestParam(value = "attachs", required = false) MultipartFile[] attachs) {
String companyLicPicPath = null;// 文件路径
String orgCodePicPath = null;
String errorInfo = null;
boolean flag = true;
//String path = request.getSession().getServletContext().getRealPath("statics" + File.separator + "uploadfiles");
String path="E:\\liujinhua\\img";
logger.info("uploadFile path ======================>" + path);
for (int i = 0; i < attachs.length; i++) {
MultipartFile attach = attachs[i];
if (!attach.isEmpty()) {// 判断文件是否为空，不为空则上传
if (i == 0) {
errorInfo = "uploadFileError";
} else if (i == 1) {
errorInfo = "uploadOcError";
}
String oldFileName = attach.getOriginalFilename();// 原文件名
logger.info("uploadFile oldFileName ===================>" + oldFileName);
String prefix = FilenameUtils.getExtension(oldFileName);// 原文件后缀
logger.debug("uploadFile profix================>" + prefix);
int filesize = 500000;
logger.debug("uploadFile size===================>" + attach.getSize());
if (attach.getSize() > filesize) {// 上传大小不得超过500KB
request.setAttribute(errorInfo, "*上传大小不得超过 500KB");
return "useradd";
} else if (prefix.equalsIgnoreCase("jpg") || prefix.equalsIgnoreCase("png")
|| prefix.equalsIgnoreCase("jpeg") || prefix.equalsIgnoreCase("pneg")) {// 上传图片格式不正确
String fileName = System.currentTimeMillis() + RandomUtils.nextInt(1000000) + "_Personal.jpg";// 重新定义的文件名
logger.debug("new fileName==========" + attach.getName());
File targetFile = new File(path, fileName);//将path(实际存储路径)放入文件类中if (!targetFile.exists()) {
targetFile.mkdirs();
}
// 保存
try {
attach.transferTo(targetFile);
} catch (Exception e) {
e.printStackTrace();
request.setAttribute(errorInfo, "*上传失败！");
flag = false;
}
if (i == 0) {
// companyLicPicPath = path + File.separator + fileName;
companyLicPicPath = "/statics/uploadfiles/" + fileName;
} else if (i == 1) {
// orgCodePicPath = path + File.separator + fileName;
orgCodePicPath = "/statics/uploadfiles/" + fileName;//此处使用虚拟路径加文件名
}
logger.debug("companyLicPicPath:" + companyLicPicPath);
logger.debug("orgCodePicPath:" + orgCodePicPath);
} else {
request.setAttribute(errorInfo, "* 上传图片格式不正确");
flag = false;
}
}
}
if (flag) {
provider.setCreatedBy(((User) session.getAttribute(Constants.USER_SESSION)).getId());// 创建人
logger.debug("创建人----》" + ((User) session.getAttribute(Constants.USER_SESSION)).getId());
provider.setCreationDate(new Date());// 创建时间
provider.setCompanyLicPicPath(companyLicPicPath);
provider.setOrgCodePicPath(orgCodePicPath);
if (providerService.add(provider)) {
return "redirect:/provider/providerlist.html";
}
}
return "provideradd";
}
（完成！！！）
