可能的問題

1. 配置了數據庫連接池：

問題： 配置了數據庫連接池：spriing.datasource.type: com.mysql.cj.jdbc.MysqlConnectionPoolDataSource
解決辦法 改用阿里巴巴的連接池

1. pom文件添加依賴 <dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.6</version></dependency>2. 修改 yml 文件 spriing.datasource.type: com.alibaba.druid.pool.DruidDataSource
