Java后台实现极光推送有两种方式，一种是使用极光推送官方提供的推送请求API：https://api.jpush.cn/v3/push，另一种则是使用官方提供的第三方Java SDK，这里先进行第一种方式推送的实现代码：
import org.apache.http.HttpResponse;import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.alibaba.fastjson.JSONArray;
import net.sf.json.JSONObject;
import sun.misc.BASE64Encoder;
/**

@SuppressWarnings({ "deprecation", "restriction" })
public class JiguangPush {
private static final Logger log = LoggerFactory.getLogger(JiguangPush.class);
private String masterSecret = "xxxxxxxxxxxxxxxxxxxx";
private String appKey = "xxxxxxxxxxxxxxxxxxx";
private String pushUrl = "https://api.jpush.cn/v3/push";
private boolean apns_proction = true;
private int time_to_live = 86400;
private static final String ALERT = "推送信息";
/**

public void jiguangPush(){
String alias = "123456";//声明别名
try{
String result = push(pushUrl,alias,ALERT,appKey,masterSecret,apns_proction,time_to_live);
JSONObject resData = JSONObject.fromObject(result);
if(resData.containsKey("error")){
log.info("针对别名为" + alias + "的信息推送失败！");
JSONObject error = JSONObject.fromObject(resData.get("error"));
log.info("错误信息为：" + error.get("message").toString());
}
log.info("针对别名为" + alias + "的信息推送成功！");
}catch(Exception e){
log.error("针对别名为" + alias + "的信息推送失败！",e);
}
}
/**

* @param alias
* @param alert
* @return json
*/
public static JSONObject generateJson(String alias,String alert,boolean apns_proction,int time_to_live){
JSONObject json = new JSONObject();
JSONArray platform = new JSONArray();//平台
platform.add("android");
platform.add("ios");
JSONObject audience = new JSONObject();//推送目标
JSONArray alias1 = new JSONArray();
alias1.add(alias);
audience.put("alias", alias1);
JSONObject notification = new JSONObject();//通知内容
JSONObject android = new JSONObject();//android通知内容
android.put("alert", alert);
android.put("builder_id", 1);

ios.put("extras", ios_extras);

options.put("time_to_live", Integer.valueOf(time_to_live));
options.put("apns_proction", apns_proction);
json.put("platform", platform);
json.put("audience", audience);
json.put("notification", notification);
json.put("options", options);
return json;
}
/**

public static String push(String reqUrl,String alias,String alert,String appKey,String masterSecret,boolean apns_proction,int time_to_live){
String base64_auth_string = encryptBASE64(appKey + ":" + masterSecret);
String authorization = "Basic " + base64_auth_string;

byte[] key = str.getBytes();
BASE64Encoder base64Encoder = new BASE64Encoder();

return strs;
}
}
以上代码中使用的是第一种方式实现推送，下面介绍第二种方式：使用java SDK
import org.slf4j.Logger;import org.slf4j.LoggerFactory;
import cn.jiguang.common.ClientConfig;
import cn.jiguang.common.resp.APIConnectionException;
import cn.jiguang.common.resp.APIRequestException;
import cn.jpush.api.JPushClient;
import cn.jpush.api.push.PushResult;
import cn.jpush.api.push.model.Options;
import cn.jpush.api.push.model.Platform;
import cn.jpush.api.push.model.PushPayload;
import cn.jpush.api.push.model.audience.Audience;
import cn.jpush.api.push.model.notification.AndroidNotification;
import cn.jpush.api.push.model.notification.IosNotification;
import cn.jpush.api.push.model.notification.Notification;
/**
* java后台极光推送方式二：使用Java SDK
*/
@SuppressWarnings({ "deprecation", "restriction" })
public class JiguangPush {
private static final Logger log = LoggerFactory.getLogger(JiguangPush.class);
private static String masterSecret = "xxxxxxxxxxxxxxxxx";
private static String appKey = "xxxxxxxxxxxxxxxx";
private static final String ALERT = "推送信息";
/**
* 极光推送
*/
public void jiguangPush(){
String alias = "123456";//声明别名
log.info("对别名" + alias + "的用户推送信息");
PushResult result = push(String.valueOf(alias),ALERT);
if(result != null && result.isResultOK()){
log.info("针对别名" + alias + "的信息推送成功！");
}else{
log.info("针对别名" + alias + "的信息推送失败！");
}
}
/**
* 生成极光推送对象PushPayload（采用java SDK）
* @param alias
* @param alert
* @return PushPayload
*/
public static PushPayload buildPushObject_android_ios_alias_alert(String alias,String alert){
return PushPayload.newBuilder()
.setPlatform(Platform.android_ios())
.setAudience(Audience.alias(alias))
.setNotification(Notification.newBuilder()
.addPlatformNotification(AndroidNotification.newBuilder()
.addExtra("type", "infomation")
.setAlert(alert)
.build())
.addPlatformNotification(IosNotification.newBuilder()
.addExtra("type", "infomation")
.setAlert(alert)
.build())
.build())
.setOptions(Options.newBuilder()
.setApnsProction(false)//true-推送生产环境 false-推送开发环境（测试使用参数）
.setTimeToLive(90)//消息在JPush服务器的失效时间（测试使用参数）
.build())
.build();
}
/**

* @param alias
* @param alert
* @return PushResult
*/
public static PushResult push(String alias,String alert){
ClientConfig clientConfig = ClientConfig.getInstance();
JPushClient jpushClient = new JPushClient(masterSecret, appKey, null, clientConfig);
PushPayload payload = buildPushObject_android_ios_alias_alert(alias,alert);
try {
return jpushClient.sendPush(payload);
} catch (APIConnectionException e) {
log.error("Connection error. Should retry later. ", e);
return null;
} catch (APIRequestException e) {
log.error("Error response from JPush server. Should review and fix it. ", e);
log.info("HTTP Status: " + e.getStatus());
log.info("Error Code: " + e.getErrorCode());
log.info("Error Message: " + e.getErrorMessage());
log.info("Msg ID: " + e.getMsgId());
return null;
}
}
}
可以看出使用Java SDK实现推送的方式很简单，代码量也少，理解起来也不难，官方提供的SDK中讲很多内容都实现了，我们只是需要配置一下信息，然后发起推送即可。需要注意的是使用第二种方式，需要导入极光官网提供的jar包。
直接在maven中的pom文件中加入：
<dependency><groupId>cn.jpush.api</groupId>
<artifactId>jpush-client</artifactId>
<version>3.2.15</version>
</dependency>
注意：在这里极有可能会出现jar包冲突：具体哪个包我也忘记了，好像是个日志包，你找到后删除即可。
原本我们项目中也是采用第二种方式实现的，但是最后在提交代码时发现一个问题，那就是虽然我们只是带入了官网提供的那三个jar包，但是最后一统计，竟然无缘无故增多了80+个jar包，如此多的jar包提交过于臃肿，而且不现实，所以才临时改变方案，采用第一种方式进行编码。
代码中采用的是别名方式进行推送，需要在在手机APP端进行别名设置，最好就是在用户登录之后就设置好，这样只要用户登录一次，它的绑定别名就可以保存到极光服务器，而我们推送时，指定这个别名，就能将信息推送到对应用户的手机上。
其实我们发起推送请求，只是将信息发送到了极光服务器之上，这个信息有一个保存时限，默认一天，只要用户登录手机APP，极光服务器就会将信息自动推送到对应别名的手机上，由此可见，信息并非由我们后天直接推送到手机，而是通过极光服务器这个中转站，而这正式极光的工作。
注意：这里告知一个技巧，这个别名设置的时候，其实直接将用户ID设置为别名即可，既方便，又安全，不用再去想办法生成一个唯一的串来进行标识，甚至需要在后台数据库中用户表中新增字段。

引入上述这些包之后，就可以进行开发了。
这里需要特别说明的两点是：
1、通过 HttpClient client = new DefaultHttpClient(); 获得HttpClient对象不支持https，需要自己重写。
2、我们的MD5编码要和服务器那边的一样。（我用我自己写的MD5编码验证的时候，总是验证失败，后来跟他们的技术人员要了他们的md5的实现方式就通过验证了）
好了，废话不多说了，接下来是贴代码的时候了：
类MySSLSocketFactory用来实现对https的支持
[java] view plain copy
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ssl.SSLSocketFactory;
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("TLS");
public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(truststore);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslContext.getSocketFactory().createSocket();
}
}
类ClientUtil 获取可以支持https的HttpClient对象，调用MySSLSocketFactory 来取得
[java] view plain copy
import java.security.KeyStore;
import org.apache.http.HttpVersion;
import org.apache.http.client.HttpClient;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.PlainSocketFactory;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpParams;
import org.apache.http.params.HttpProtocolParams;
import org.apache.http.protocol.HTTP;
public class ClientUtil {
public static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
e.printStackTrace();
return new DefaultHttpClient();
}
}
}
接下来就是调用JPush的api来推送消息了
[java] view plain copy
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
/**
* 调用远程api实现推送
* @author naiyu

*/
public class PushMsgUtil {
// public static final String PUSH_URL = "https://api.jpush.cn:443/sendmsg/sendmsg";
public static final String PUSH_URL = "http://api.jpush.cn:8800/sendmsg/sendmsg";
public static void pushMsg(String msg) {
BasicNameValuePair name = new BasicNameValuePair("username", "test"); //用户名
BasicNameValuePair sendno = new BasicNameValuePair("sendno", "3621"); // 发送编号。由开发者自己维护，标识一次发送请求
BasicNameValuePair appkeys = new BasicNameValuePair("appkeys", "your appkeys"); // 待发送的应用程序(appKey)，只能填一个。
BasicNameValuePair receiver_type = new BasicNameValuePair("receiver_type", "4");
//验证串，用于校验发送的合法性。
BasicNameValuePair verification_code = new BasicNameValuePair("verification_code", getVerificationCode());
//发送消息的类型：1 通知 2 自定义
BasicNameValuePair msg_type = new BasicNameValuePair("msg_type", "1");
BasicNameValuePair msg_content = new BasicNameValuePair("msg_content", msg);
//目标用户终端手机的平台类型，如： android, ios 多个请使用逗号分隔。
BasicNameValuePair platform = new BasicNameValuePair("platform", "android");
List<BasicNameValuePair> datas = new ArrayList<BasicNameValuePair>();
datas.add(name);
datas.add(sendno);
datas.add(appkeys);
datas.add(receiver_type);
datas.add(verification_code);
datas.add(msg_type);
datas.add(msg_content);
datas.add(platform);
try {
HttpEntity entity = new UrlEncodedFormEntity(datas, "utf-8");
HttpPost post = new HttpPost(PUSH_URL);
post.setEntity(entity);
HttpClient client = ClientUtil.getNewHttpClient();
HttpResponse reponse = client.execute(post);
HttpEntity resEntity = reponse.getEntity();
System.out.println(EntityUtils.toString(resEntity));
} catch (Exception ex) {
ex.printStackTrace();
}
}
private static String getVerificationCode() {
String username = "test"; //username 是开发者Portal帐户的登录帐户名
String password = "pasword";
int sendno = 3621;
int receiverType = 4;
String md5Password = StringUtils.toMD5(password);; //password 是开发者Portal帐户的登录密码
String input = username + sendno + receiverType + md5Password;
String verificationCode = StringUtils.toMD5(input);
return verificationCode;
}
public static void main(String[] args) {
String msg = "{\"n_title\":\"来点外卖\",\"n_content\":\"你好\"}";
System.out.println(msg);
PushMsgUtil.pushMsg(msg);
}
}
