一、代码实现

1.配置类—Env.java

package com.ray.jpush.config;

/**@desc  : 极光推送接入配置
 * 
 * @author: shirayner
 * @date  : 2017年9月27日 下午4:57:36
 */

public class Env {

    /**
     * 1.极光推送后台APPKEY,MASTER_SECRET
     */
    public static final String APP_KEY = "354fb5c3dd4249ec11bc545d";
    public static final String MASTER_SECRET = "8976605bf8a9ef9d8d97a8c2";
}

2.消息服务类—MessageService.java 

package com.ray.jpush.service.message;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

import com.ray.jpush.util.HttpHelper;

/**@desc  : 极光推送消息服务

 * @author: shirayner
 * @date  : 2017年11月29日 下午2:24:16
 */
public class MessageService {
    private static final Logger log= LogManager.getLogger(MessageServiceTest.class);

    //1.发送通知
    private static final String SEND_NOTIFICATION_URL="https://api.jpush.cn/v3/push";

    /**

     *   JSONObject
     */
    public static JSONObject sendNotification(String registration_id,String alert,String appKey,String masterSecret) {
        
        String base64_auth_string = CommonUtil.encryptBASE64(appKey + ":" + masterSecret);
        String authorization = "Basic " + base64_auth_string;
        
        String data=generateJson(registration_id,alert).toString();
       
        log.debug("authorization:"+authorization);
        log.debug("data:"+data);
       
        return HttpHelper.doPost(SEND_NOTIFICATION_URL, data, authorization);
    }
    
    
    /**
     * @desc :  2.拼装请求json
     *   
     * @param registration_id     注册id
     * @param alert    通知内容

     *   JSONObject
     */
    private static JSONObject generateJson(String registration_id,String alert){
        JSONObject json = new JSONObject();
        
        JSONArray platform = new JSONArray();   //1.推送平台设置
        platform.add("android");
        platform.add("ios");
        
        JSONObject audience = new JSONObject();       //2.推送设备指定,即推送目标
        JSONArray registrationIdList = new JSONArray();

        android.put("alert", alert);                      //设置通知内容
        android.put("builder_id", 1);
        JSONObject android_extras = new JSONObject();//android额外参数

     * @param authorization  验证字段,Authorization: Basic base64_auth_string
     *                       其中 base64_auth_string 的生成算法为:base64(appKey:masterSecret)
     *                       即,对 appKey 加上冒号,加上 masterSecret 拼装起来的字符串,再做 base64 转换。
     * @return
     * @throws Exception 
     *   JSONObject
     */
    public static JSONObject doPost(String url, String data ,String authorization) {

import sun.misc.BASE64Encoder;

/**@desc  :

public class CommonUtil {


    /**
     * @desc :BASE64加密工具
     *  
     * @param str  待加密字符串
     * @return 
     *   String
     */
    public static String encryptBASE64(String str) {
        byte[] key = str.getBytes();
        BASE64Encoder base64Encoder = new BASE64Encoder();
        String strs = base64Encoder.encodeBuffer(key);
        return strs;

5.消息服务测试类—MessageServiceTest.java

package com.ray.jpush.service.message;

import org.junit.Test;

import com.ray.jpush.config.Env;

/**@desc  : 极光推送测试类
 * 
 * @author: shirayner
 * @date  : 2017年11月29日 下午3:54:42
 */
public class MessageServiceTest {

    /**
     * @desc :1.发送通知
     *   
     *   void
     */
    @Test
    public void testSendNotification() {
        String registration_id="121c83f760211fa5944";
        //String alert="hello,my honey!";
        String alert="您好:\\n 于岩军在2017-11-15提出了一张金额为5的费用报销单 BX10017110076 ,需要审批! \\n\\n\\n===================================================================\\n\\n秒针费用管理系统\\n\\n本邮件由系统自动发送,请勿回复。";
        String appKey=Env.APP_KEY;
        String masterSecret=Env.MASTER_SECRET;
        
        MessageService.sendNotification(registration_id, alert, appKey, masterSecret);
