无法将 Spring 启动应用程序升级到 Flyway 7.0.0

Question

我正在尝试升级我的 Spring Boot 2.3.4 应用程序以使用 Flyway 7.0.0（最新版本）。以前它使用的是 Flyway 6.5.6。 build.gradle中的相关条目如下所示。

buildscript {
  ext {
    flywayVersion = "7.0.0" // changed from 6.5.6
  }
}

plugins {
  id "org.flywaydb.flyway" version "${flywayVersion}"
}

dependencies {
  implementation "org.flywaydb:flyway-core:${flywayVersion}"
}

flyway {
  url = "jdbc:postgresql://0.0.0.0:5432/postgres"
  user = "postgres"
  password = "secret"
}

当我启动应用程序时出现以下错误，例如./gradlew bootRun

Answer 1

基本上，请参阅 Philip 对您的问题的评论。

Flyway 7.x.x 当前不兼容 Spring Boot 2.3.4

临时解决方案是降级到 Flyway 6.5.7（最后一个 6.x.x 版本），直到 Spring Boot 2.3.5 发布。

Answer 2

降级到 Flyway 6.5.7 有效。

Answer 3

在 Flyway 7 中，migrate 的签名已更改。

要让 Flyway 7.x.x 与 Spring Boot 2 一起工作。3.x 您可以提供自定义 FlywayMigrationStrategy 实现，它会调用正确的 migrate 方法。

import org.flywaydb.core.Flyway;
import org.springframework.boot.autoconfigure.flyway.FlywayMigrationStrategy;
import org.springframework.stereotype.Component;

@Component
public class FlywayMigrationStrategyImpl implements FlywayMigrationStrategy {
    @Override
    public void migrate(Flyway flyway) {
        flyway.migrate();
    }
}
