Flyway与spring boot的集成不在嵌入式H2数据库上执行迁移脚本

Question

我试图在Spring Boot应用程序中使用Flyway对嵌入式H2数据库进行迁移演示。

应用程序.属性

logging.level.org.org.springframework=DEBUG
server.port=8181
spring.h2.console.enabled=true
spring.h2.console.path=/h2
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver
spring.flyway.baseline-on-migrate=true
spring.jpa.hibernate.ddl-auto=none

迁移-db/migration下的脚本(V2__create_shipwreck.sql)

CREATE TABLE SHIPWRECK(ID INT AUTO_INCREMENT,
    NAME VARCHAR(255),
    DESCRIPTION VARCHAR(2000),
    CONDITION VARCHAR(255),
    DEPTH INT,
    LATITUDE DOUBLE,
    LANGITUDE DOUBLE,
    YEARS_DISCOERED INT);

信息7284---[main]o.f.c.i.s.jdbctableSchemaHistory：创建架构历史记录表：“public”.“flyway_schema_history”

信息7284---[main]o.f.core.internal.command.dbmigrate:架构“public”的当前版本:<<空架构>>

信息7284---[main]o.f.core.internal.command.dbmigrate：正在将架构“public”迁移到版本2-创建shipwreck

信息7284---[main]J.LocalContainerEntityManagerFactoryBean：为持久性单元“default”构建JPA容器EntityManagerFactory

信息7284---[main]o.hibernate.jpa.internal.util.loghelper:hhh000204:正在处理PersistenceUnitInfo[名称：默认...]

main]org.Hibernate.version:hhh000412:Hibernate核心{5.2.14.final}

main]org.hibernate.cfg.environment:HHH000206:找不到hibernate.properties

main]o.Hibernate.Annotations.common.version:hcann000001:Hibernate Commons Annotations{5.0.1.final}

main]org.hibernate.dialt.Dialect:hhh000400:使用方言:org.hibernate.dialt.h2方言

H2数据库表界面

启动Spring Boot应用程序后，表还没有创建，那么这里有什么问题呢？

Answer 1

我也遇到了同样的问题，在将application.properties更改为datasource.url（而不是mem）后，这个问题得到了解决

能够创建详细信息正确的表:spring.datasource.url=jdbc:h2:file:~/dasboot

应用程序.属性

logging.level.org.org.springframework=DEBUG
server.port=8080

spring.h2.console.enabled=true
spring.h2.console.path=/h2

spring.datasource.url=jdbc:h2:file:~/dasboot
spring.datasource.username=sa
spring.datasource.password=
