Description:

Parameter 1 of method connectionServerManager in com.github.linyuzai.connection.loadbalance.autoconfigure.ConnectionLoadBalanceConfiguration$DiscoveryConnectionServerManagerConfiguration required a bean of type 'org.springframework.cloud.client.serviceregistry.Registration' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.cloud.client.serviceregistry.Registration' in your configuration.

大佬，今天进行调试的时候发现了这个异常，似乎是多线程导致的问题
java.lang.IllegalStateException: The remote endpoint was in state [TEXT_PARTIAL_WRITING] which is an invalid state for called method

平常使用websocket发送消息都会使用synchronized

public void send(String message) throws IOException {
        synchronized (session) {
            this.session.getBasicRemote().sendText(message);
        }
    }

我翻看了一下源码好像并没有进行处理😥😥

大佬，你好。
我在idea中启动了两个相同模块，端口不一样，都注册上nacos

这是网关的转发配置

两个都启动后连接出现了问题

拿到 ws 地址去测试发现是可以连接上的

当在nacos注册了多实例的服务偶尔回去先这个错误。

完全不会用呀，我有一个这样的需求，我在主程序里面写了一个接口，想在第二个程序里面实现这个接口，然后动态的加载到主程序里面，然后强制转换成主程序接口，他提示类型转换异常，查阅资料后估计是类加载器不一致导致的。不知道作者这个支持这种方式吗，或者说我应该怎么做。

继承的字段中如果存在未导入的类，就会编译失败，如果预先引入类，可能会被IDE的，Optimize imports移除。

刚刚试了concept-download-spring-boot-starter的1.2.2版本，@Download注解什么都不写，方法返回 file:前缀的字符串，路径对应的文件不存在，结果得到了一个zip，里面包含一个文件，内容为空

大佬，是不是不支持 JDK 17 + springboot 3.0 版本呀，将版本替换后发现无法注入 WebSocketLoadBalanceConcept bean 了,还是我哪里设置的不对。

您好，我最近在使用您的动态加载外部类的项目时遇到一个问题想请教您一下，场景是让项目去读取指定目录下的jar包，然后解析jar包里面的yaml文件，然后再根据配置文件去用jar包里面的类生成实例，在这种情况下我发现，当jar包名相同，里面的配置文件不同的时候，如果上传->删除->再上传，这个时候在@OnPluginExtract方法里面解析的配置时候还会是第一次上传的配置文件，好像相同名的jar包只会解析一次。我的测试系统是ubuntu18.04，jdk为1.8。同时我也测试了在Windows下运行的时候则不会出现这个问题

如果没有引入spring-aop系列包，download注解实际上不生效的

大神，你好，基于路径推送使用PathMessage可以实现，针对用户推送使用UserMesage可以实现，如何实现根据路径给某些用户推送啊，类似于这样: concept.send(new PathMessage(msg,path,listUserId))。如果我使用我自己定义一个消息类PathUserMessage，不知道 setBroadcast(false);是true，还是false。能否提供一个默认实现。

public class PathUserMessage extends ObjectMessage {
public PathUserMessage(Object payload, String path,String... userIds) {
this(payload,path, Arrays.asList(userIds));
}

public PathUserMessage(Object payload,String path, Collection<String> userIds) {
    super(payload);
    setBroadcast(false);
    getHeaders().put(PathSelector.KEY, path);
    getHeaders().put(UserSelector.KEY, String.join(",", userIds));
}

大佬，我想要获取不被发送的消息，请问要怎么使用 DeadMessageEvent 这个类呢😱😱

问题描述：
请问大佬要怎么断开集群中其它机器客户端的 websocket 连接呢？
集群中有 A B 两台机器，如何在 A 机器上断开客户端在 B 机器上的连接。
异常堆栈：

代码示例：

该模式不支持分布式。多实例发布消息有bug。客户端绑定的实例才能触达到客户端。

例如；相同用户打开两个页面（两个客户端，一个用户支持多端的需求，在手机或者电脑端打开相同的ws地址），一个连接到后端实例A，一个连接到后端实例B，如果在实例A发送消息，绑定实例A的客户端收到消息，绑定实例B的客户端收不到消息。反之一样。

send 和 sendPath 模式正常（支持分布式）

指定服务地址未生效，请问还需要其他配置吗？

问题描述：
在两台机器上部署了服务

• 当 websocket 连接数接近 500 的时候服务会变的不可用，看 websocket 中的消息还可以正常发送却无法再建立新的连接。
  是需要设置最大连接数量吗？

• 服务异常日志，当客户端断开 websocket 连接的时候也会出现这样的情况

代码示例：

依赖名称：
concept-websocket-loadbalance-spring-boot-starter
依赖版本：
1.X和2.x都有这个问题
问题描述：
一、有server.servlet.context-path的话会导致自身实例连接订阅其他实例失败这个比较好解决在1.x版本可以通过在项目下重写这个类
com.github.linyuzai.connection.loadbalance.core.subscribe.AbstractConnectionSubscriber

2.x的版本我没看到在哪里可以重写这个订阅地址
二、有server.servlet.context-path的话会导致致命问题：PathMessage全部变成死信消息导致接收不到
比如我要根据用户userId=729来做路径发送消息（这里是想不管同一用户有多少个client实例都要接收到消息）
异常堆栈：
发送消息后websocket client 没有接收到消息：

debug进去查看原因：

当我去掉server.servlet.context-path测试正常：

代码示例：
appliaction.yml:

发送消息代码：

Could not read script 'E:\workspace\concept\sonatype.gradle' as it does not exist

依赖名称：

依赖版本：

问题描述：使用异步回调转为同步返回包，通过kafka返回消息ID来唤醒线程，第一次请求正常，点击第二次就会报请求超时，设置超时时间为3秒，收到kakfa消息是在三秒内

异常堆栈：

代码示例：

SpringCloud:Hoxton.SR12 + SpringBoot:2.3.12.RELEASE + nacos + Gateway
error: Field propertiesFactory in org.springframework.cloud.netflix.ribbon.RibbonClientConfiguration required a bean of type 'org.springframework.cloud.netflix.ribbon.PropertiesFactory' that could not be found.

AcknowledgeRabbitListenerEndpoint 实现的RabbitListenerEndpoint 这个接口在springboot3.0 增加了一个方法
/**
* Whether this endpoint is for a batch listener.
* @return {@link Boolean#TRUE} if batch.
* @SInCE 3.0
*/
@nullable
Boolean getBatchListener();
