在spring boot的启动类上加上@EnableWebSocketServer
注解,并在该注解上设置好需要扫描的路径。
@SpringBootApplication
@EnableWebSocketServer(webSocketScanPackage = {"com.vue.demo.vue"})
public class VueDemoApplication {
public static void main(String[] args) {
SpringApplication.run(VueDemoApplication.class, args);
}
}
@WebSocketController
@WebSocketRequestMapping("/user/")
public class UserController {
/**
* 这个userService就是我们平时在spring里面写的service
*/
@Autowired
private UserService userService;
/**
* 功能描述: 模拟字段请求的方式来实现根据用户ID来获取用户数据
*
* @param userId 用户的流水ID
* @return
*/
@WebSocketRequestMapping("getUserVoByUserId")
public UserVo getUserVoByUserId(String userId) {
return userService.getUserVoByUserId(userId);
}
}
只需要实现WebsocketSecurity接口即可实现自定义的权限拦截处理
public class WebsocketSecurityImpl implements WebsocketSecurity {
/**
* 这个authService就是我们平时在spring里面写的service
**/
@Autowired
private AuthService authService;
@Override
public int level() {
return 10;
}
@Override
public Boolean authentication(ChannelHandlerContext ctx, SocketRequest socketRequest) {
Boolean isPass = authService.authUrl(socketRequest.getUrl());
System.out.println("----我在这里做了一个模拟的鉴权过程---");
if(!isPass){
ctx.channel().writeAndFlush(new TextWebSocketFrame(JsonUtils.objToJson(new SocketResponse(HttpResponseStatus.UNAUTHORIZED.code(), "授权不通过!"))));
}
return isPass;
}
}
只需实现WebSocketHandlerListenter
接口即可实现监听。
public class WebSocketHandlerListenterImpl implements WebSocketHandlerListenter {
/**
* 这个webSocketCloseService就是我们平时在spring里面写的service
**/
@Autowired
private WebSocketCloseService webSocketCloseService;
@Override
public int level() {
return 0;
}
/**
* 功能描述: 当浏览器端的通道关闭的时候的响应处理方法
*
* @param ctx 当前的通道对象
*/
@Override
public void channelInactive(ChannelHandlerContext ctx) {
System.out.println("当前关闭的通道的id是:" + ctx.channel().id().asLongText());
webSocketCloseService.removeChannel(ctx.channel().id().asLongText());
}
@Override
public void handleShake(ChannelHandlerContext ctx) {
System.out.println("当前开启的通道的id是:" + ctx.channel().id().asLongText());
}
}
