2024-10-14T14:12:01.172+08:00 ERROR 12216 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed 怎么改

这个错误信息显示的是Spring Boot应用程序运行时遇到的问题，通常包含时间、错误级别（ERROR）、线程ID（12216）、日志消息以及异常堆栈跟踪。`Application run failed`表示应用启动失败。

要解决这个问题，你需要按照以下步骤操作：

1. **检查错误日志详细信息**：错误级别提到的是`ERROR`，所以需要查看完整的堆栈跟踪（Stacktrace），它会告诉你具体的错误原因，可能是依赖问题、配置错误或者是代码中的bug。

   $ java -jar your-app.jar

或者如果你正在使用IDEA等集成开发环境，找到对应的 logs 文件夹（如application.log）来查看详细日志。

2. **定位问题源**：
- 检查是否有未初始化的bean，或者bean创建过程中出现问题。
- 确认是否所有的依赖都正确添加并版本兼容。
- 配置文件（application.properties或application.yml）里的设置是否有误。

3. **修复错误**：根据错误的具体原因修改源代码、配置文件，或者更新相关的库。

4. **重启应用**：尝试用命令行再次启动应用看问题是否已经解决。如果还是失败，可以考虑清除缓存、删除target目录再重建项目。

5. **测试**：一旦解决了错误，对应用进行全面的功能性和压力测试，确保所有功能正常。

java如何将字符串"2024-10-14T16:53:57.336525000"中的T去除替换为空格

在Java中，你可以使用`String`类的`replace()`方法或者正则表达式`replaceAll()`方法来移除字符串中的特定字符。这里是一个例子，展示如何使用`replace()`方法：

public class Main {
    public static void main(String[] args) {
        String dateStr = "2024-10-14T16:53:57.336525000";
        String newDateStr = dateStr.replace("T", " ");
        System.out.println(newDateStr);
    }
}

如果你想要使用正则表达式，可以这样做：

Pattern pattern = Pattern.compile("T");
Matcher matcher = pattern.matcher(dateStr);
String newDateStr = matcher.replaceAll(" ");
System.out.println(newDateStr);

这两个方法都会将"T"替换为一个空格，得到的结果是："2024-10-14 16:53:57.336525000"。

根据您提供的最新错误日志，MySQL 在关闭过程中没有显示任何明显的错误。这表明 MySQL 进程正常关闭。

为了进一步排除问题，我建议您尝试执行以下步骤：

1. 检查 MySQL 进程是否已完全终止。您可以使用以下命令检查：

   ps aux | grep mysql

确保没有任何与 MySQL 相关的进程正在运行。

2. 尝试手动启动 MySQL 服务，并查看是否有任何错误消息。使用以下命令启动服务：

   sudo systemctl start mysqld

3. 如果手动启动 MySQL 服务时出现错误，请检查 `/var/log/mysql/error.log` 中的最新错误日志，以获取详细的错误信息。您可以使用以下命令查看最新的错误日志：

   sudo tail -n 50 /var/log/mysql/error.log

如果问题仍然存在，请提供最新的日志信息和任何其他相关配置文件的内容，以便我能够更好地帮助您解决问题。
