我能够通过 Spring 的 jdbc:initialize-database 进程创建一些 MySQL 表。现在，每次我尝试运行 SQL 脚本来删除/创建表时，都会收到拒绝连接的响应。此外，在 STS 中，我在 Application Services 框中没有 MySQL 条目，但我在 Instances 框中看到一个条目，其中 id、主机、cpu、内存、磁盘、正常运行时间全为 0。当我尝试添加 MySQL 服务时，我收到“服务名称已被使用”的错误......所以，我想我已经扭曲了一些东西，只是想重置我的 MySQL 数据库。数据无关紧要，我可以轻松地重新开始。

    ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.jdbc.datasource.init.DataSourceInitializer#0': Invocation of init method failed; nested exception is org.springframework.dao.DataAccessResourceFailureException: Failed to execute database script; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure

目前，cloudfoundry.com 存在一个影响服务的错误。如果用户创建了一个名为“sample”的服务并且用户 b 尝试创建一个同名的服务（可以是任何服务）“sample”，用户 b 将看到“错误 506 服务名称已存在”错误。@Cloud Foundry 团队知道这一点，他们正在努力。

因此，暂时尝试创建一个具有不同名称的服务，您应该很可能会创建该服务。
