Oracle11g Spring Boot：如何通过Spring.datasource中的外部配置属性设置Oracle生产数据库连接的重试尝试

我是

Spring

新手，我想为

Oracle

设置

重试尝试

，它与我们的

Spring-Boot-Java应用程序关联。我有几个
spring.datasource
属性是在application.yml文件中指定的

数据源：

driverClassName: oracle.jdbc.driver.OracleDriver
url: "jdbc:oracle:thin:@//xxx-xxx-x-xxx:1521/database"
username: scott
password: tiger

我引用了这个，它提供了一个常见的Spring引导属性列表，但我找不到为Spring引导数据源设置重试次数的属性。当连接失败时，spring引导是否会自动重试？为数据源设置重试尝试次数有意义吗

我经常收到
连接重置
错误，因此我计划添加重试尝试，以确保在连接失败时重试。以下是堆栈跟踪：
