存数据的服务器配置:

 <Server port="8003" shutdown="SHUTDOWN">
 <Connector port="8004" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />
    <Connector port="8006" protocol="AJP/1.3" redirectPort="8443" />

执行存储的代码:

 public class SSMUtils {

    public static final String pic_HOST="http://loaclhost:8004/ssm_image";

}
 @Controller
@RequestMapping("/upload")
public class UploadController {

    @RequestMapping("/uploadPic")

        String suffix = sur.substring(sur.lastIndexOf("."));
        //创建jersy服务器
        Client client = Client.create();

        WebResource resource = client.resource(SSMUtils.pic_HOST+"/upload/"+newFileName+suffix);

        resource.put(String.class, fbytes);

程序员接私活怎样防止做完了不给钱?
