Spring Cloud Connectors 1.2.1 发布，更新如下： Heroku Connector Relational Databases The Heroku cloud connector now recognizes the DATABASE_URL environment variable when detecting PostgreSQL database. Redis Heroku Redis is now supported. Spring Connector Relational Databases When creating a DataSource, Spring Cloud Connectors will look for a pooling DataSource implementation on the classpath and choose one based on a default priority. The priority of detection has been changed to more closely match the order used in Spring Boot. Applications can customize the priority order of pooled DataSource implementations using either Java configuration or XML configuration. DataSourceConfig will now accept a map of key/value pairs to allow setting arbitrary properties of the created DataSource. This allows overriding of the default JDBC driver class name and validation query set up by Connectors, in addition to other properties of the DataSource. This can be used by Java configuration or XML configuration. 完整更新列表请看： resolved issues in GitHub. Spring Framework 是一个开源的Java/Java EE全功能栈（full-stack）的应用程序框架，以Apache许可证形式发布，也有.NET平台上的移植版本。 该框架基于 Expert One-on-One Java EE Design and Development（ISBN 0-7645-4385-7）一书中的代码，最初由 Rod Johnson 和 Juergen Hoeller等开发。Spring Framework 提供了一个简易的开发方式，这种开发方式，将避免那些可能致使底层代码变得繁杂混乱的大量的属性文件和帮助类。 Spring Cloud Connectors 1.2.1 发布下载地址
