原因分析

数据库连接超时或网络不稳定导致通信中断。

解决方案

  • 调整数据库连接超时设置：

    • * JDBC URL: 在数据库连接的URL中添加 connectTimeout 和 socketTimeout 参数。例如：jdbc:mysql://localhost:3306/dbname?connectTimeout=5000&socketTimeout=5000 (单位为毫秒，可根据实际情况调整)。
    * 程序代码: 在使用数据库连接池时，配置连接池的 connectionTimeout 和 idleTimeout 等参数。

  • 检查网络稳定性：确保数据库服务器与应用程序之间网络连接稳定，无丢包或高延迟。

    • 预防措施

  • 设置合理的数据库连接超时时间，避免长时间空闲连接导致意外断开。

  • 在网络环境复杂的情况下，考虑在应用程序端实现连接重试机制。
