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

Question

我正在尝试使用 Flyway 在 Spring Boot 应用程序的嵌入式 H2 数据库上进行迁移演示。

application.properties

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

db/migration 下的迁移脚本(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);

控制台日志

H2 数据库表 UI

启动Spring Boot应用后，表还没有创建，请问这是什么问题？

Answer 1

我有同样的问题，在对 application.properties 进行更改后解决了datasource.url 到 file 而不是 mem

能够创建包含详细信息的表格正确的: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=
spring.datasource.driver-class-name=org.h2.Driver

spring.flyway.baseline-on-migrate=true
spring.jpa.hibernate.ddl-auto=none
