2 个解决方案

This is a very popular design. 这是一个非常受欢迎的设计。 Consider the fact that if one of the two servers (A or B) is down, your site will not work, unless server B is mirrored properly. 考虑以下事实：如果两个服务器（A或B）之一关闭，则除非服务器B正确镜像，否则您的站点将无法工作。

Links to images can be anywhere on the web, as long as you provide the full path in the link. 只要在链接中提供完整路径，图像链接就可以在网络上的任何地方。 Also, make sure that server B can withstand the load, since every request for a page on server A with a link to an image on server B will obviously require both servers to respond. 另外，请确保服务器B能够承受负载，因为对服务器A上的页面的每个请求（带有链接到服务器B上的图像的请求）显然都需要两个服务器都进行响应。

Yes , I have found the solution. 是的，我找到了解决方案。 Approach #1: In java application you can upload your image to your current server(A) and store with c://somefolder/ . 方法1：在Java应用程序中，您可以将图像上传到当前服务器（A）并使用c：// somefolder /进行存储。 Then from the java application transfer the image using httpclient to a different server (B) which is in php/mysql and another domain name.(Php process is easy to store and access). 然后从Java应用程序中使用httpclient将图像传输到位于php / mysql和另一个域名中的另一台服务器（B）（Php流程易于存储和访问）。 After the transfer process get the result ,file name ,url and store it with your server A database. 传输过程完成后，获取结果，文件名，URL并将其存储在服务器A数据库中。 And in successful transfer delete the file from server A folder. 并成功传输后，从服务器A文件夹中删除文件。 Now u can user the image path as server B domainname/appname/imagepath . 现在，您可以将映像路径用作服务器B domainname / appname / imagepath。

Approach #2: The same process you can use with amazon web services. 方法2：您可以对亚马逊网络服务使用相同的过程。 (if you don't want to use the second domain name of yours. （如果您不想使用您的第二个域名。
