Netty SocketIO是一个 Java 语言版本的 Socket.IO 服务器的实现，基于 Netty 框架开发，使用简单，功能强大。
在Spring Boot中包含了对Netty SocketIO的支持，只需要简单配置即可加入。
第一步：增加Netty SocketIO的依赖。
<dependency>
<groupId>com.corundumstudio.socketio</groupId>
<artifactId>netty-socketio</artifactId>
<version>1.7.11</version>
</dependency>
第二步：在Application中增加启动项
package com.ukefu;
import javax.servlet.MultipartConfigElement;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.boot.context.embedded.ErrorPage;
import org.springframework.boot.context.embedded.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.http.HttpStatus;
import com.corundumstudio.socketio.AuthorizationListener;
import com.corundumstudio.socketio.Configuration;
import com.corundumstudio.socketio.HandshakeData;
import com.corundumstudio.socketio.SocketConfig;
import com.corundumstudio.socketio.SocketIOServer;
import com.corundumstudio.socketio.annotation.SpringAnnotationScanner;
import com.ukefu.core.UKDataContext;
@EnableAutoConfiguration
@SpringBootApplication
@EnableJpaRepositories("com.ukefu.service.repository")
public class Application {
@Value("${uk.im.server.host}")
private String host;
@Value("${uk.im.server.port}")
private Integer port;
@Bean
public SocketIOServer socketIOServer()
{
Configuration config = new Configuration();
// config.setHostname("localhost");
config.setPort(port);
config.setSocketConfig(new SocketConfig());
// config.setOrigin("http://im.ukewo.com");
config.setWorkerThreads(100);
// config.setStoreFactory(new HazelcastStoreFactory());
config.setAuthorizationListener(new AuthorizationListener() {
public boolean isAuthorized(HandshakeData data) {
return true;
}
});
SocketIOServer server = new SocketIOServer(config);
server.addNamespace(UKDataContext.NameSpaceEnum.IM.toString()) ;
server.addNamespace(UKDataContext.NameSpaceEnum.AGENT.toString()) ;
return server;
}
@Bean
public MultipartConfigElement multipartConfigElement() {
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize("50MB"); //KB,MB
factory.setMaxRequestSize("100MB");
return factory.createMultipartConfig();
}
@Bean
public EmbeddedServletContainerCustomizer containerCustomizer() {
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainer container) {
ErrorPage error = new ErrorPage("/error.html");
container.addErrorPages(error);
}
};
}
@Bean
public SpringAnnotationScanner springAnnotationScanner(SocketIOServer socketServer) {
return new SpringAnnotationScanner(socketServer);
}
public static void main(String[] args) {
UKDataContext.setApplicationContext(SpringApplication.run(Application.class, args));
}
}
第三步：配置Netty Server相关代码
package com.ukefu.util.server;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
import com.corundumstudio.socketio.SocketIOServer;
import com.ukefu.core.UKDataContext;
import com.ukefu.util.server.handler.AgentEventHandler;
import com.ukefu.util.server.handler.IMEventHandler;
@Component
public class ServerRunner implements CommandLineRunner {
private final SocketIOServer server;
private IMEventHandler imEventHandler ;
private AgentEventHandler agentEventHandler ;
@Autowired
public ServerRunner(SocketIOServer server , IMEventHandler imEventHandler , AgentEventHandler agentEventHandler) {
this.server = server;
this.imEventHandler = imEventHandler ;
this.agentEventHandler = agentEventHandler ;
}
public void run(String... args) throws Exception {
server.getNamespace(UKDataContext.NameSpaceEnum.IM.toString()).addListeners(imEventHandler);
server.getNamespace(UKDataContext.NameSpaceEnum.AGENT.toString()).addListeners(agentEventHandler);
server.start();
}
}
第四步：配置消息处理的代码
package com.ukefu.util.server.handler;
import java.net.InetSocketAddress;
import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.corundumstudio.socketio.AckRequest;
import com.corundumstudio.socketio.SocketIOClient;
import com.corundumstudio.socketio.SocketIOServer;
import com.corundumstudio.socketio.annotation.OnConnect;
import com.corundumstudio.socketio.annotation.OnDisconnect;
import com.corundumstudio.socketio.annotation.OnEvent;
import com.ukefu.util.server.message.AgentStatusMessage;
import com.ukefu.util.server.message.ChatMessage;
import com.ukefu.util.server.message.NewRequestMessage;
@Component
public class IMEventHandler extends EventHandler
{
@Autowired
public IMEventHandler(SocketIOServer server)
{
super(server) ;
}
@OnConnect
public void onConnect(SocketIOClient client)
{
System.out.println(client.getSessionId());
}
//添加@OnDisconnect事件，客户端断开连接时调用，刷新客户端信息
@OnDisconnect
public void onDisconnect(SocketIOClient client)
{
System.out.println(client.getSessionId());
}
//消息接收入口，网站有新用户接入对话
@OnEvent(value = "new")
public void onEvent(SocketIOClient client, AckRequest request, NewRequestMessage data)
{
try {
String user = client.getHandshakeData().getSingleUrlParam("userid") ;
String orgi = client.getHandshakeData().getSingleUrlParam("orgi") ;
String session = client.getHandshakeData().getSingleUrlParam("session") ;
String appid = client.getHandshakeData().getSingleUrlParam("appid") ;
if(!StringUtils.isBlank(session)){
session = session.replaceAll("-", "") ;
}
if(!StringUtils.isBlank(user)){
/**
* 用户进入到对话连接 ， 排队用户请求 , 如果返回失败，表示当前坐席全忙，用户进入排队状态，当前提示信息 显示 当前排队的队列位置，不可进行对话，用户发送的消息作为留言处理
*/
InetSocketAddress address = (InetSocketAddress) client.getRemoteAddress() ;
// NewRequestMessage newRequestMessage = OnlineUserUtils.newRequestMessage(user, orgi , session , appid , address.getHostString() , client.getHandshakeData().getSingleUrlParam("osname") , client.getHandshakeData().getSingleUrlParam("browser")) ;
// /**
// * 加入到 缓存列表
// */
// NettyClients.getInstance().putIMEventClient(user, client);
//
// if(newRequestMessage!=null && !StringUtils.isBlank(newRequestMessage.getMessage())){
// MessageOutContent outMessage = new MessageOutContent() ;
// outMessage.setMessage(newRequestMessage.getMessage());
// outMessage.setMessageType(UKDataContext.MessageTypeEnum.MESSAGE.toString());
// outMessage.setCalltype(UKDataContext.CallTypeEnum.IN.toString());
//
// client.sendEvent(UKDataContext.MessageTypeEnum.STATUS.toString(), outMessage);
// }
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//消息接收入口，坐席状态更新
@OnEvent(value = "agentstatus")
public void onEvent(SocketIOClient client, AckRequest request, AgentStatusMessage data)
{
System.out.println(data.getMessage());
}
//消息接收入口，收发消息，用户向坐席发送消息和 坐席向用户发送消息
@OnEvent(value = "message")
public void onEvent(SocketIOClient client, AckRequest request, ChatMessage data)
{
System.out.println(data.getMessage());
}
}
第五步：完成配置。
