xmpp推送服务smack与springboot结合(三)

介绍

XMPP协议的推送实现采用的smack库,可以与不同的java框架整合使用,这次我使用的springboot框架实现。

这篇文章主要写代码的实现,对XMPP不清楚的,可以看前几篇文章:

java推送技术的选择(一)
openfire服务的安装(二)

搭建springboot项目

这里写图片描述
pom.xml文件,加入jar包

与smack结合主要使用的是上面的5个jar包,smack的功能还有很多,需要的可以去看看官方的API文档

1、smack-core.jar XMPP RFC规范定义的XMPP核心功能。

2、smack-extensions.jar XMPP Standards Foundation定义的扩展(XEP)功能。 包括群聊、文件传输、用户搜索等等。

官方文档地址:

配置openfire地址

#openfire服务器地址
openfire.server=127.0.0.1

发送XMPP消息

连接XMPP服务器

XMPPTCPConnectionConfiguration.Builder config=XMPPTCPConnectionConfiguration.builder();
config.setServiceName(openfireServer);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setSendPresence(true);
config.setCompressionEnabled(false);

XMPPTCPConnection con = new XMPPTCPConnection(config.build());
SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
SASLAuthentication.blacklistSASLMechanism("CRAM-MD5");
return con;

实现代码

package com.example.demo;

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.sasl.provided.SASLPlainMechanism;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;
import org.jivesoftware.smackx.search.ReportedData;
import org.jivesoftware.smackx.search.UserSearchManager;
import org.jivesoftware.smackx.xdata.Form;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**

 */
@RestController
public class SmackController {

    @Value("${openfire.server}")
    protected String openfireServer;


    @RequestMapping("")
    public Object index(String mobile, String body) {
        return sendSmackMessage(mobile, body, false);
    }




    public boolean sendSmackMessage(String mobile, String body,boolean deliveryReceiptRequest) {
        try {
            if (StringUtils.isEmpty(mobile)) {
                return false;
            }
            XMPPTCPConnection con = getXmpptcpConnection();
            con.connect();
            if (con.isConnected()) {
                SASLAuthentication.registerSASLMechanism(new SASLPlainMechanism());
                con.loginAnonymously();//匿名登录
                UserSearchManager userSearchManager=new UserSearchManager(con);
                Form searchForm=userSearchManager.getSearchForm("search."+con.getServiceName());
                Form answerForm = searchForm.createAnswerForm();
                answerForm.setAnswer("Username", true);
                answerForm.setAnswer("search", mobile);
                ReportedData data=userSearchManager.getSearchResults(answerForm,"search."+con.getServiceName());
                List<ReportedData.Row> list = data.getRows();

                for (ReportedData.Row row : list) {
                    for (String jid : row.getValues("jid")) {
                        Message m = new Message();
                        m.setBody(body);//设置消息。
                        m.setTo(jid);//设置发送目标
                        if(deliveryReceiptRequest){
                            m.setType(Message.Type.normal);
                        }else{
                            m.setType(Message.Type.headline);
                        }
                        m.setSubject(body);
                        con.sendStanza(m);
                    }
                }
            }
            con.disconnect();
            return true;
        } catch (Exception e) {
            e.printStackTrace();
            return false;
        }
    }

    private XMPPTCPConnection getXmpptcpConnection() {
        XMPPTCPConnectionConfiguration.Builder config=XMPPTCPConnectionConfiguration.builder();
        config.setServiceName(openfireServer);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
        config.setSendPresence(true);
        config.setCompressionEnabled(false);

        XMPPTCPConnection con = new XMPPTCPConnection(config.build());
        SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
        SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
        SASLAuthentication.blacklistSASLMechanism("CRAM-MD5");
        return con;
    }

}

代码解释

  1. getXmpptcpConnection方法为连接XMPP
  2. sendSmackMessage为发送消息的方法,mobile为接收人,body为发送的内容,deliveryReceiptRequest为是否是离线消息
  3. 代码中采用的是匿名发送,也可以指定一个账号作为发送方
  4. 这里我根据需要还用了模糊匹配账号,给匹配的账号都发送了消息
  5. Message.Type.normal与Message.Type.headline是是否离线消息

测试

启动项目后,浏览器输入:http://localhost:8080/?mobile=18758120932&body=测试测试

登录spray客户端,就会接收到消息
这里写图片描述

结束语

以上代码使用就是我在项目中对推送服务的使用,如果在APP内用这样的推送业务,可以选择XMPP服务作为你的选择。

更多的smack的使用可以查看官方文档,聊天,分组,添加好友等功能,完全可以满足你的各种需求。
