android集合SSH框架服务端应该怎么操作

public class LoginProtocol extends BaseProtocol{

 private List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
private final static String URL = "http://192.168.1.110:8080/healthServer/login";
public boolean checkLogin(User user){
    try {  

        addNameValuePair("name", user.getUsername());
        addNameValuePair("password", user.getPassword());

        pack(URL);
        System.out.println("URL是：：：：：：："+URL);
        parse();
        JSONObject obj = this.getJSON();
        System.out.println("输出obj是"+obj);
        if(obj.getString("result").equals("false")){
            return false;
        }else{
            return true;
        }
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("mmmmmmmmmmmmmmmmm");
        return false;
    }
}

}

public class BaseProtocol {

private StringBuilder sb = new StringBuilder();  

private HttpClient httpClient;
private HttpPost httpRequest;
private HttpResponse response;  

private List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();  

BaseProtocol() {
    httpClient = new DefaultHttpClient();
}  

/**
 * 向服务器端发送请求
 *
 * @param url
 * @throws Exception
 */
protected void pack(String url) throws Exception {
    httpClient = new DefaultHttpClient();
    httpRequest = new HttpPost(url);
    try{
    httpRequest.setEntity(new UrlEncodedFormEntity(nameValuePair,HTTP.UTF_8));
    //取得HTTP response
    System.out.println("httpRequest是"+httpRequest);
    System.out.println(nameValuePair+"//////////////////////");
    System.out.println("entity是；；；；；；；；；"+httpRequest.getEntity());
    response = httpClient.execute(httpRequest);
    System.out.println(response);
    }catch (Exception e){
    e.printStackTrace();
    }
}

/**
 * 得到返回数据
 *
 * @param url
 * @return
 * @throws Exception
 */
protected void parse() throws Exception {
    // TODO 状态处理 500 200
    if (response.getStatusLine().getStatusCode() == 200) {  

        System.out.println("ssssssssssssssssss"+response.getStatusLine().getStatusCode());
        BufferedReader bufferedReader2 = new BufferedReader(
                new InputStreamReader(response.getEntity().getContent()));  

        System.out.println("jjjjjjjjjjjjjjjjjjjjjjjjj"+bufferedReader2);
        for (String s = bufferedReader2.readLine(); s != null; s = bufferedReader2
                .readLine()) {
            sb.append(s);
            System.out.println(sb+"****************");
        }
        System.out.println("执行Parse()中的If语句了");
    }
}  

/**
 * 向服务器发送信息
 *
 * @param key
 * @param value
 */
public void addNameValuePair(String key, String value) {
    nameValuePair.add(new BasicNameValuePair(key, value));
    System.out.println(nameValuePair);
}  

/**
 * 返回JSONObject对象数据模型
 *
 * @return
 * @throws JSONException
 */
public JSONObject getJSON() throws JSONException {  

    return new JSONObject(sb.toString());
}

}
struts.xml文件：

/main/hint/errorpage/error.jsp
/main/hint/errorpage/javaerror.jsp
/WEB-INF/main/message.jsp

     <action name="login" class="action.login.LoginAction" method="logins">

        <result name="success2" type="json"><param name="includeProperties">result</param>
            <param name="ignoreHierarchy">false</param></result>
        <result name="success1" >/main/loginSuccess.jsp</result>
        <result name="false" >/main/loginFail.jsp</result>
    </action>
    在loginAnction中我应该怎么处理，怎么接收android传过来的HttpPost，怎么将httpRequest.setEntity(new UrlEncodedFormEntity(nameValuePair,HTTP.UTF_8))中的NameValuePair中的用户信息读出来
    或者，我在服务端应该怎么处理，请大神们指点一下，项目现在需要写web和android同时写

解决方案

LOgin方法使用服务端的URL调用方法，执行post方法，传出用户名和密码，然后对应的给与解析。返回true

解决方案二：

后台不管用什么框架，只是给你客户端（app），返回解析的结果的。
一般的流程是：
1. app端调用后台的接口去查询数据
2. 后台根据接口查询出数据之后，组装成json等格式返回给app
2. app端在根据返回结果解析，作出响应。
