极光推送java后台集成实例

1、首先去极光官网下载java对应sdk，官网通道：
https://docs.jiguang.cn/jpush/resources/#sdk_1

2、把对应的jar包复制到自己web项目的lib下，并添加进去。

3、接下来直接使用就可以了，可能会有报错，但都不难解决，下述的代码涵盖推送几乎所有的情况

public class JpushClientUtil {
private final static String masterSecret = "";
private final static String appKey = "";

private static JPushClient jPushClient = new JPushClient(masterSecret,appKey);

public static int sendToRegistrationId(List<String> registrationList,String notification_title, String msg_title, String msg_content, String extrasparam,String type) {
    int result = 0;
    try {
        PushPayload pushPayload=null;
        if(type.equals("0")){//自定义推送
        	pushPayload=JpushClientUtil.buildPushObject_all_registrationId_alertWithTitle(registrationList,notification_title,msg_title,msg_content,extrasparam);

    }
