Android 调用 Smart Framework构建的Rest服务

首先感谢下黄勇大神写出这么好用的javaweb框架。

Smart Framework详细内容请点击：http://www.oschina.net/p/smart-framework

首先使用smart建立Rest服务的方法，个人分析可用两种方式：

第一种，直接在service层上创建Rest服务

服务端：

@Service@Rest("/userservice")@Consumes(MediaType.APPLICATION_JSON)@Produces(MediaType.APPLICATION_JSON)public class UserServiceImpl implements UserService {    @POST    @Path("/login/{username}/{password}")    @Override    public void login(@PathParam("username") String username, @PathParam("password") String password) {        SecurityHelper.login(username, password, false);            }}

android客户端：

public static String sendRequest(HttpRequestMethod methodEnum,            String url, Map<String, String> paramsMap) {        String result = null;        HttpUriRequest req = methodEnum.createRequest(url);        req.addHeader("Content-Type",MediaType.APPLICATION_JSON);         try {            if (paramsMap != null) {                JSONObject jsonObj = new JSONObject(paramsMap);        StringEntity entity = new StringEntity(jsonObj.toString());        ((HttpEntityEnclosingRequest)req).setEntity(entity);   }            HttpResponse httpResp = httpClient.execute(req);             if (httpResp.getStatusLine().getStatusCode() == HTTP_200) {                result = EntityUtils.toString(httpResp.getEntity(), DEFAULT_LOCAL_ENCODE);            } else {            }        } catch (Exception e) {            e.printStackTrace();        }        return result;    }    public static String login(String username ,String password){        return sendRequest(HttpRequestMethod.HttpPost,RootUrl+"/rest/userservice/login/"+username+"/"+password,null);    }

第二中是在action层上建立Rest服务，这种其实不用建立Rest服务，直接调用action地址即可

直接上android端代码

public static String sendRequest(HttpRequestMethod methodEnum,            String url, Map<String, String> paramsMap) {        String result = null;        HttpUriRequest req = methodEnum.createRequest(url);                 try {            if (paramsMap != null) {                <span style="color:#ff0000;"><strong>((HttpEntityEnclosingRequest)req).setEntity(new UrlEncodedFormEntity(                        keyValueToValuePairList(paramsMap), DEFAULT_REMOTE_ENCODE));</strong></span>   }            HttpResponse httpResp = httpClient.execute(req);             if (httpResp.getStatusLine().getStatusCode() == HTTP_200) {                result = EntityUtils.toString(httpResp.getEntity(), DEFAULT_LOCAL_ENCODE);            } else {            }        } catch (Exception e) {            e.printStackTrace();        }        return result;    }       public static String login(String username ,String password){        Map<String, String> paramsMap = new HashMap<String, String>();        paramsMap.put("username", "admin");        paramsMap.put("password", "admin");        return sendRequest(HttpRequestMethod.HttpPost,RootUrl+"/login,paramsMap);    }
