java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

This error occurs when the Java application is trying to use the WebSocket API, but the WebSocket server container is not available.

There could be several reasons for this error, such as:

1. The WebSocket server container is not properly configured or initialized.
2. The WebSocket server container is not available on the server where the application is deployed.
3. The application is trying to use the WebSocket API in a non-WebSocket environment.

To resolve this issue, you can try the following solutions:

1. Check if the WebSocket server container is properly configured and initialized. Make sure that all the necessary dependencies are included in the classpath.
2. Verify that the WebSocket server container is available on the server where the application is deployed. If not, install the WebSocket server container and configure it properly.
3. Ensure that the application is running in a WebSocket environment and not in a non-WebSocket environment.

If these solutions do not resolve the issue, you can seek help from a Java expert or consult the WebSocket API documentation for further guidance.

nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available

这个错误信息表明在项目启动过程中出现了一个异常，具体是"nested exception is java.lang.IllegalStateException: javax.websocket.server.ServerContainer not available"。这个异常表示WebSocket的ServerContainer不可用。通常这种情况是因为对应的依赖没有正确加载或者配置问题导致的。您可以检查以下几个方面来解决这个问题：

1. 确保您的项目正确引入了相关的WebSocket依赖。您可以检查您的项目的pom.xml或者build.gradle文件，确保相关的依赖已经正确添加。

2. 检查您的配置文件中是否正确配置了WebSocket相关的配置。您需要确保配置了正确的WebSocket容器，并且相关的配置项没有错误。

3. 如果您使用的是Spring Boot，可以尝试在启动类上添加`@EnableWebSocket`注解以启用WebSocket支持。

4. 如果以上方法都无法解决问题，可能是由于版本不兼容或者其他特定的环境问题导致的。您可以尝试搜索相关的错误信息，查看是否有其他开发者遇到相似的问题并给出了解决方案。
