1.创建一个新的maven工程并且部署tomcat，用于做图片服务器并且在webapp下创建uploads文件
2.在应用服务器上的pom.xml导入坐标
<!--跨服务器上传文件--> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-core</artifactId> <version>1.18.1</version> </dependency> <dependency> <groupId>com.sun.jersey</groupId> <artifactId>jersey-client</artifactId> <version>1.18.1</version> </dependency>

<h3>跨服务器文件上传</h3> <form action="/user/fileupload" method="post" enctype="multipart/form-data"> 选择文件：<input type="file" name="upload"><br> <input type="submit" value="上传"> </form>

@Controller
@RequestMapping("/user")
public class UserConteoller {
/**

@RequestMapping("/fileupload")
public String fileupload(HttpServletRequest request, MultipartFile upload) throws Exception {
System.out.println("文件上传");
//定义上传文件服务器路径
String path = "http://localhost:9090/uploads/";
//获取上传文件的名称
String filename = upload.getOriginalFilename();
System.out.println(filename);
//把文件的名称设置位置 uuid
String uuid = UUID.randomUUID().toString().replace("-", "");
System.out.println(uuid);
filename = uuid + "_" + filename;
//完成跨服务器上传
//创建客户端对象
Client client = Client.create();
//和图片服务器进行连接
WebResource webResource = client.resource(path + filename);
//上传文件
webResource.put(upload.getBytes());
return "success";
}
}
