针对移动端的java服务器，接收和json返回数据

本人新手，刚参加工作，前段时间让我写安卓服务端，java语言，使用的是SSH框架，去百度谷歌，不过这方面的好像不是太多（也可能是我没发现）。
----------------------------------------------------
使用http协议，安卓那边的代码我不太懂，不过在我本机上测试代码的时候 我是使用http请求，以get方式提交。可以调用。
再说我的服务端，Struts+spring+hibernate，传输的是json数据。
剩下的不多说，见代码；
这是我的BaseAction，用于接收json数据：

import com.opensymphony.xwork2.ActionSupport;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
import org.apache.struts2.ServletActionContext;

public class BaseAction extends ActionSupport {
	private static final long serialVersionUID = 1L;

	public HttpServletRequest getRequest() {
		return ServletActionContext.getRequest();
	}

	public HttpServletResponse getResponse() {
		return ServletActionContext.getResponse();
	}

	public HttpSession getSession() {
		return getRequest().getSession();
	}

	public HttpSession getSession(boolean create) {
		return getRequest().getSession(create);
	}

	public PrintWriter createPrintWriter() {
		HttpServletResponse response = ServletActionContext.getResponse();
		response.setContentType("application/x-json;charset=utf-8");
		PrintWriter out = null;
		try {
			out = ServletActionContext.getResponse().getWriter();
		} catch (IOException e) {
			e.printStackTrace();
		}
		return out;
	}

	public JSONObject readJsonObject() {
		BufferedReader reader = null;
		JSONObject json = null;
		String value = null;
		try {
			reader = getRequest().getReader();
			value = reader.readLine();
		} catch (IOException e) {
			e.printStackTrace();
		}
		json = (JSONObject) JSONSerializer.toJSON(value);
		String jsonString = json.getString("jsonString");
		JSONObject jsonObject = JSONObject.fromObject(jsonString);
		return jsonObject;
	}
}

UserAction

import java.sql.Timestamp;

import net.sf.json.JSONObject;

import org.springframework.beans.factory.annotation.Autowired;

		} catch (Exception e) {
			e.printStackTrace();
			this.flag = false;
			this.message = "Input type error!";
			return "success";

		if ((name.length() > 20) || (name.length() < 4)) {

			BuyerExt buyerExt = new BuyerExt();

		} catch (Exception e) {

			this.message = "System error!";
		}
		return "success";
	}

	public String validPwd() {
		System.out.println("------------validPassword-------------");
		int userId = 0;
		String password = null;
		try {
			JSONObject jsonObject = super.readJsonObject();

			userId = jsonObject.getInt("userId");
			password = jsonObject.getString("password");
		} catch (Exception e) {

					MD5Util.getMD5(password));
			if (isValid) {

		} catch (Exception e) {

			this.flag = false;
			this.message = "system error!";

	}

	public String getInfo() {

		return this.user;
	}
	public boolean isFlag() {

}

下面的struts配置文件（部分代码），

<package name="user" extends="json-default" namespace="/user">
        <!-- 用户注册 -->
        <action name="register" class="userAction" method="register">
            <result type="json">
                <param name="includeProperties">
                    flag,
                    message,
                    isSuccess,
                    info,
                    user\.id,
                    user\.address,
                    user\.name,
                    user\.phone,
                    user\.email,
                    user\.area
                </param>
            </result>
        </action>
        <!-- 获取区域列表 -->
        <action name="getAreas" class="areaAction">
            <result type="json">
                <param name="includeProperties">
                    flag,
                    message,
                    detail\[\d+\]\.id,
                    detail\[\d+\]\.name,
                    detail\[\d+\]\.pid
                </param>
            </result>
        </action>

不过现在并没有加密，只是初期的代码，以后还会继续上传加密之后的，当然如果你现在有更好的方法，请留言，多多交流！
