Android与Tomcat远程访问

小雨点点789

　　因为要做一个软件注册的功能，所以今天做了一个小例子，这里的服务器是自己的tomcat服务器，做过j2ee的应该是再熟悉不过了。
　　RegisterActivity.java
　　public class RegisterActivity extends Activity {private static final String uriConnection = "http://10.0.2.2:8080/Register/servlet/RegisterServlet";//private static final String uriConnection = "http://192.168.0.5:8080/Register/servlet/RegisterServlet";Button registerButton;Button registerLaterButton;ProgressDialog progressDialog;EditText firstText;EditText lastText;EditText emailText;@Overrideprotected void onCreate(Bundle savedInstanceState) {setContentView(R.layout.register);super.onCreate(savedInstanceState);firstText = (EditText) findViewById(R.id.register_first_name_id);lastText = (EditText) findViewById(R.id.register_last_name_id);emailText = (EditText) findViewById(R.id.register_email_id);registerButton = (Button) findViewById(R.id.register_button_id);registerLaterButton = (Button) findViewById(R.id.register_later_button_id);registerButton.setOnClickListener(registerListener);registerLaterButton.setOnClickListener(registerLaterButtonListener);}Handler handler = new Handler() {public void handleMessage(Message msg) {progressDialog.dismiss();finish();};};View.OnClickListener registerListener = new View.OnClickListener() {@Overridepublic void onClick(View v) {String firstName = firstText.getText().toString();String lastName = lastText.getText().toString();String emailName = emailText.getText().toString();progressDialog = ProgressDialog.show(RegisterActivity.this,"Register", "Registering waitting.....");registerToHost(firstName, lastName, emailName);}};// 处理客户端和服务器端的请求private void registerToHost(String firstName, String lastName,String emailName) {HttpPost httpRequest = new HttpPost(uriConnection);HttpResponse httpResponse = null;List<NameValuePair> params = new ArrayList<NameValuePair>();if (!firstName.equals("") && !lastName.equals("")&& !emailName.equals("")) {params.add(new BasicNameValuePair("firstName", firstName));params.add(new BasicNameValuePair("lastName", lastName));params.add(new BasicNameValuePair("emailName", emailName));}try {httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));httpResponse = new DefaultHttpClient().execute(httpRequest);} catch (UnsupportedEncodingException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (ClientProtocolException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}// 处理从服务器短来的数据if (httpResponse.getStatusLine().getStatusCode() == 200) {System.out.println("Connection OK");handler.sendEmptyMessage(0);/** byte[] data = new byte[2048]; try { data =* EntityUtils.toByteArray(httpResponse.getEntity()); } catch* (IOException e) { // TODO Auto-generated catch block* e.printStackTrace(); }*/}}View.OnClickListener registerLaterButtonListener = new View.OnClickListener() {@Overridepublic void onClick(View v) {finish();}};}

　　而在服务器端很简单就是一个servlet接收传递过来的值就可以了，然后通过传递过来的值做相应的操作。
　　public class RegisterServlet extends HttpServlet{public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{String firstName=request.getParameter("firstName");String lastName=request.getParameter("lastName");String emailName=request.getParameter("emailName");//response.setContentType(C);System.out.println("firstName:"+firstName);System.out.println("lastName:"+lastName);System.out.println("emailName:"+emailName);}}
