mysql - SpringBoot Cloud Foundry 覆盖数据库池大小 - 通信链路故障

标签 mysql spring-boot cloud-foundry

经过研究，我发现 Spring Boot 在部署到云时创建的默认池大小为 4。我正在使用 Spring Boot 1.3.7 部署到 Cloud Foundry，并连接到 MySQL 服务。我想增加默认池大小。我正在按照此博客中概述的步骤进行操作，但收到以下错误。在服务中使用自动配置时，连接到数据库没有问题，因此可以访问数据库。任何想法或建议将不胜感激!!!!

最佳答案

我已经准备好了。由于某种原因，Spring Boot 从我的本地 application.yml 文件中获取数据库连接 URL，而不是在部署的 manifest.yml 中使用 Cloud Foundry 服务。当我从本地 application.yml 中删除连接信息时，它现在可以工作了。

关于mysql - SpringBoot Cloud Foundry 覆盖数据库池大小 - 通信链路故障，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51847784/
