问答 nutz-boot tomcat方式集成websocket问题
发布于 1547天前 作者 qq_8c799e25 1622 次浏览 复制 上一个帖子 下一个帖子

以前是用nutz+tomcat集成的websocket，现在改成nutzboot+tomcat集成websocket，但连接ws报404，自定义的WebSocket好像没有初始化成功，

配置:

<properties>
        <nutzboot.version>2.4.0.v20200427</nutzboot.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

....

代码：

//ServerEndpoint是websocket的必备注解, value是映射路径, configurator是配置类.
@ServerEndpoint(value = "/ws/wsh", configurator=NutWsConfigurator.class)
@IocBean // 使用NutWsConfigurator的必备条件
public class MyWebsocket extends AbstractWsEndpoint {
 // 并不需要你马上实现任何方法,它也马上能工作
	
	public WsHandler createHandler(Session session, EndpointConfig config) {
//        return new MySimpleWsHandler(); // 是的,返回你自己的实现类就可以了,需要每次新建哦
	     return new WebWsHandler(); // 是的,返回你自己的实现类就可以了,需要每次新建哦
    }

自带支持，不需要手工添加依赖

您是说把nutz-plugins-websocket依赖去掉吧，我试过连ws还是404，jdk是1.8的，还有哪里的问题？

知道啥原因了，没有注入

tomcat的方式有bug啊，

case1: 采用jetty的方式(注释掉nutzboot-starter-tomcat依赖)，websocket功能正常：

jetty.port=8088
jetty.host=0.0.0.0
jetty.contextPath=/xxx

case2:采用tomcat的方式，注释掉nutzboot-starter-jetty， websocket异常（404）

tomcat.port=8088
tomcat.host=0.0.0.0
tomcat.contextPath=/xxx

<nutzboot.version>2.4.0.v20200427</nutzboot.version>


javax.websocket
javax.websocket-api
1.1
provided

我昨天说成功，其实是jetty方式， tomcat一直没有成功过

case3:采用Undertow的方式， websocket正常

undertow.port=8088
undertow.host=0.0.0.0
undertow.contextPath=/xxx

再还原成tomcat方式，还是异常， 看来很可能是tomcat方式有bug
