connector+configured+to+listen+on++Port+9091+filed+to+start

connector configured to listen on Port 9091 出现启动失败的原因可能是由于以下几点：
1. 端口冲突：请确保没有其他进程或服务正在使用9091端口。可以使用命令`netstat -ano | findstr :9091`来查看是否有其他进程在监听该端口。
2. 配置错误：请检查Tomcat的配置文件，确保Connector的配置正确。特别注意检查是否正确指定了监听端口为9091。
3. 防火墙设置：确保防火墙允许9091端口的连接。可以尝试暂时关闭防火墙并重新启动Connector，看是否能够成功启动。
4. 其他问题：如果以上步骤都没有解决问题，可以尝试在Tomcat的日志文件中查找相关错误信息，以帮助定位问题所在。

Unable to connect to localhost:6379+

It seems that you are encountering an issue with connecting to localhost on port 6379. There could be a few reasons for this problem. Let's try to troubleshoot it together.

1. Check if Redis is running: Make sure that Redis server is up and running on your local machine. You can check the status by running the following command in your terminal:

   redis-cli ping

If it returns "PONG", that means Redis is running. If not, you may need to start Redis server.

2. Verify the connection details: Double-check the connection details, such as the hostname (usually "localhost") and port number (6379) you are using to connect to Redis. Make sure they are correct.

3. Firewall or security settings: Check if there are any firewall rules or security settings that might be blocking the connection to Redis. Ensure that the necessary ports are open and accessible.

4. Confirm Redis configuration: Ensure that Redis is properly configured to listen on the correct network interface and port. You can check the configuration file (redis.conf) for any specific settings related to binding addresses or ports.

5. Restart Redis: If none of the above steps resolve the issue, try restarting the Redis server to see if it helps establish the connection.

If you have tried these steps and are still unable to connect to localhost:6379, please provide more details about your setup, including the operating system, programming language, and any error messages you encounter. This will help in further troubleshooting the issue.

This+application+has+no+configured+error+view

这个错误通常出现在使用某些框架或库时，当应用程序出现错误时，它会尝试显示一个错误视图，但是由于没有正确配置，所以会出现"This application has no configured error view"的错误信息。

要解决这个问题，需要根据具体情况进行调试和排查。以下是一些可能的解决方法：

1. 检查应用程序的配置文件，确保已正确配置错误视图。
2. 检查应用程序的依赖项，确保它们已正确安装和配置。
3. 检查应用程序的代码，查找可能导致错误视图无法正常工作的问题。
4. 如果使用的是某个框架或库，可以查看它们的文档或社区论坛，寻求帮助和解决方案。
