原因:org.flywaydb.core.api.FlywayException:迁移失败！和Spring Cloud DataFlow [英] Caused by: org.flywaydb.core.api.FlywayException: Migration failed ! and Spring Cloud DataFlow
本文介绍了原因:org.flywaydb.core.api.FlywayException:迁移失败！和Spring Cloud DataFlow的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在研究Spring batch and Spring Cloud Data Flow示例.在此示例中，我通过引用
I'm working on Spring batch and Spring Cloud Data Flow example. In this example, I've developed spring-cloud-data-flow-server and MySQL DB instead of default H2 DB by taking reference from Database Configs for MySQL DB
Flyways和MySQL版本似乎有问题，因为最新版本的Flyways不会获取最新版本的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 !

推荐答案
MySQL v5.5不接受DATETIME数据类型的参数.将查询更新为以下内容:
MySQL v5.5 doesn't accept an argument for the DATETIME datatype. Update your query to the following:
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)
);
请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，您将不会对应用程序将在其中运行的环境之间的不兼容性感到惊讶.
Consider using the same MySQL version for local development as your remote deployment servers. This way, you won't be surprised by incompatibilities between the environments your application will run within.
