原因：org.flywaydb.core.api.FlywayException：迁移失败！和 Spring 云数据流
Caused by: org.flywaydb.core.api.FlywayException: Migration failed ! and Spring Cloud DataFlow
我正在处理 Spring batch and Spring Cloud Data Flow 示例。在此示例中，我通过参考 Database Configs for MySQL DB
开发了 spring-cloud-data-flow-server 和 MySQL 数据库而不是默认的 H2 数据库
看起来 Flyways 和 MySQL 版本有问题，因为最新版本的 Flyways 没有获取最新版本的 MySQL DB.
错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.internal.command.DbMigrate$FlywayMigrateException: Migration failed !

可以试试最新版的flyway-core吗？已修复此区域中的一些问题。

MySQL v5.5 不接受 DATETIME 数据类型的参数。将您的查询更新为以下内容：
CREATE TABLE TASK_LOCK (
LOCK_KEY CHAR(36) NOT NULL,
REGION VARCHAR(100) NOT NULL,
CLIENT_ID CHAR(36),
CREATED_DATE DATETIME NOT NULL, -- note the omitted (6) argument --
constraint LOCK_PK primary key (LOCK_KEY, REGION)
);
考虑使用与远程部署服务器相同的 MySQL 版本进行本地开发。这样，您就不会对您的应用程序 运行 所处环境之间的不兼容性感到惊讶。

MySQL v5.5 不接受 DATETIME 数据类型的参数。将您的查询更新为以下内容：
CREATE TABLE TASK_LOCK (
LOCK_KEY CHAR(36) NOT NULL,
REGION VARCHAR(100) NOT NULL,
CLIENT_ID CHAR(36),
CREATED_DATE DATETIME NOT NULL, -- note the omitted (6) argument --
constraint LOCK_PK primary key (LOCK_KEY, REGION)
);
考虑使用与远程部署服务器相同的 MySQL 版本进行本地开发。这样，您就不会对您的应用程序 运行 所处环境之间的不兼容性感到惊讶。
