Docker部署SpringBoot到Render失败求助

全天尝试通过Docker将SpringBoot项目部署至Render平台，中途解决各类错误后，当前遇到如下问题：手动触发部署后，日志仅输出到镜像上传成功就终止，无任何错误说明，但部署标记为失败。

排查方向

日志缺失：当前日志仅展示镜像构建和上传流程，容器启动阶段日志未输出，需前往Render平台的「服务日志」板块查看启动失败的具体报错
配置拼写错误：application.properties中spring.datasorce.password存在拼写错误，应改为spring.datasource.password，此错误会导致数据库密码读取失败，无法建立连接
数据库URL格式错误：生产环境的spring.datasource.url格式不正确，正确格式应为jdbc:mysql://<数据库主机>:<端口>/<数据库名>?useSSL=true&serverTimezone=UTC，需替换为Render提供的真实数据库地址
Java版本兼容性：Spring Boot 2.6.7官方仅支持Java 8、11、17，使用Java 19可能存在兼容性问题，建议将Java版本降至17，或升级Spring Boot至支持Java 19的版本（如3.x系列）
端口配置：Render部署Docker服务需指定端口，Spring Boot默认使用8080端口，需在Render服务设置中将端口设为8080，或在application.properties中添加server.port=${PORT:8080}以适配Render的环境变量端口
数据库连通性：确认Render上的MySQL数据库已正确创建，网络权限开放，且数据库用户拥有足够的读写权限
