【问题描述】：
早上好。问题是我的 tomcat 容器在 webapps 文件夹中有我的 war 文件（spring boot 应用程序）没有与我在 kubernetes 中的 mysql 容器连接。
当我检查 tomcat pod 的日志时，它说未知主机期望：mysql 和 jdbc 通信链接失败。
war 文件中存在 application.properties 文件
# Set here configurations for the database connection
# Connection url for the database "account-database"
spring.datasource.url = jdbc:mysql://${MYSQL_DB_HOST}:${MYSQL_DB_PORT}/data-core?allowPublicKeyRetrieval=true
spring.datasource.url1 = jdbc:mysql://${MYSQL_DB_HOST}:${MYSQL_DB_PORT}/data-core
# Username and password
spring.datasource.username = ${MYSQL_DB_USER}
spring.datasource.password = ${MYSQL_DB_PASSWORD}
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
spring.datasource.tomcat.max-wait=360000
driver=com.mysql.jdbc.Driver
url=jdbc:mysql://${MYSQL_DB_HOST}:${MYSQL_DB_PORT}/data-core
username=${MYSQL_DB_USER}
password=${MYSQL_DB_PASSWORD}

注意：当我尝试从 tomcat 容器 ping mysql 时，我得到未知主机 mysql。
目前我可以看到tomcat主页购买我无法在tomcats manager app中启动war文件。我怀疑这是由于tomcat无法连接到mysql容器。请帮助。
【问题讨论】：

路径中是否有 mysql 连接器...？

mysql 连接器 ??我不能理解你。我已经在 lib 文件夹中有所有必要的 jar 文件
