 1 | ## 即时通讯插件简介
 2 |     很多聊天功能都是基于第三方聊天api，比如融x，而且第三方运营成本比较高。那为何不研发一款高并发聊天插件呢？
 3 |     
 4 |     环境 springboot2.x、jdk8、maven
 5 |     框架 netty、fastjson
 6 | 
 7 | ## 使用说明
 8 |     1.通讯插件源码下载到本地。命令行输入`maven install`。项目工程中引入插件依赖。
 9 |     `<dependency>
10 |         <groupId>io.github.yangyouwang</groupId>
11 |         <artifactId>springboot-starter-im</artifactId>
12 |         <version>0.0.1-SNAPSHOT</version>
13 |     </dependency>`
14 |    ![引入jar](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/1.jpg "1.png")
15 |    
16 |     2.resource中application.yml配置插件通讯端口。
17 |     `im:
18 |       netty:
19 |         port: 8888 # 配置聊天端口` 
20 |    ![配置端口](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/2.jpg "2.png")
21 |    
22 |     3.启动类main方法加入启动插件代码
23 |     `NettyBooter nettyBooter = SpringUtil.getBean(NettyBooter.class);
24 |             nettyBooter.start();`
25 |    ![配置端口](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/3.jpg "3.png")
26 |    
27 |     4.控制台打印出：启动 Netty 成功。默认访问路径`ws://localhost:8888/im/ws`
28 |    ![启动成功](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/4.jpg "4.png")
29 |    ![启动成功](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/5.jpg "5.png")
30 |               
31 |  ## 如何在程序中获取消息
32 |  
33 |      代码加入事件监听（参数是DataContentEvent，而不是DataContent）
34 |     `@Component
35 |            public class ChatMsgListener {
36 |                @EventListener
37 |                public void getData(DataContentEvent dataContentEvent) {
38 |                    System.out.println("收到消息了" + dataContentEvent.getDataContent());
39 |                }
40 |          }`
41 |          
42 |    ![加入事件](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/6.jpg "6.png")
43 |    ![控制台输出](https://raw.githubusercontent.com/YangYouWang/springboot-starter-im/master/demo/img/7.jpg "7.png")
44 |    
45 |     开源不易，切勿白嫖。
46 | 
47 |  **革命尚未成功，同志仍须努力**
