HttpClient封装：

package com.tp.soft.http;

import java.net.SocketTimeoutException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;

/**

public class HttpUtil {
    public static HttpResponse getHttpResonse(String serverPath, Map<String, String> params, String encoding){
        List<NameValuePair> pairs = new ArrayList<NameValuePair>();
        if(null != params && !params.isEmpty()){

        HttpClient client = new DefaultHttpClient(httpParams);
        return client;
    }
}

IO封装：

package com.tp.soft.io;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class IOUtil {
    public String getJson(InputStream is){
        String jsonData = "";
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        String resData = "";
        try {
            while((resData=br.readLine())!=null){
                jsonData += resData;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            try {
                br.close();
                isr.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return jsonData;
    }
}

Constant类：

package com.tp.soft.util;

public class Constant {
    public final static String ENCODING = "UTF-8";
    public final static String SERVER_PATH = "http://xxx.xxx.xxx.xxx:8081/wsTest1/ws/rest/";
    public final static String LOGIN_METHOD = "login";
    public final static String LOGINURL = SERVER_PATH + "loginService/" + LOGIN_METHOD;
}

服务器用的是rest版的webservice

        Result result = new Result();
        AuUserVo auUserVo = new AuUserVo();
        auUserVo.setLogin_name(username);
        AuUser auUser;
        try{
            auUser = loginDao.findUser(auUserVo);
        }catch (DataAccessException e) {
            LOG.error("【ibatis】登录异常", e);
            throw new BaseServiceException(e.getLocalizedMessage());
        }
        
        if(null == auUser){
            result.setErrMsg(Constant.LOGIN_NAME_ERROR);
        }else if(!password.equals(auUser.getLogin_pwd())){

        }else{
            result.setSuccess(true);
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("user", auUser);
            result.setData(map);
        }
        
        return result;
    }

}

dao里面就是ibatis调用数据库 这边就不贴了
