【问题描述】：
我正在从 2.3.12.RELEASE 升级到 spring boot 2.7.0，因为它有漏洞。 我的应用程序使用 c3p0 进行连接池，我需要继续使用它。

财产：spring.datasource.type=com.mchange.v2.c3p0.ComboPooledDataSource
打破这一点的是 Spring Boot 2.5.x 或更高版本中 DataSourceBuilder 的变化。
数据源构建器：
private enum DataSourceProperty {
URL(false, \"url\", \"URL\"),
DataSourceBuilder 将在 ComboPooledDataSource 类中查找 setUrl 或 setURL，并且该类具有 setJdbcUrl 方法，因此出现异常。
有什么建议不要手动创建数据源 bean 并在不破坏代码的情况下使用自动配置？
编辑： 应用程序属性
spring.datasource.url=jdbc:mysql://db-url:3307/service
spring.datasource.username=user
spring.datasource.password=pass
spring.datasource.type=com.mchange.v2.c3p0.ComboPooledDataSource
spring.datasource.pool.driverClass=com.mysql.cj.jdbc.Driver
-
spring.datasource.url您需要在应用程序属性中针对此属性传递 url -
是的，我通过了这就是为什么这个例外。
