【问题描述】：

你能帮忙解释为什么flyway不能安装脚本吗 ?

我的架构是空的，只有一个创建 flyway 的表。但它也是空的。

如何正确配置 FlyWay？我的脚本有以下形式

V1__20170918_Initial_structure.sql

我的源代码

    LoggerUtil.getDEBUG_LOGGER().info("FlyWayMigrator - flywayMigrateStart");
    String flywayMinVersion = FlyWayProperty.getInstance().getProperty(FlyWayProperty.FLYWAY_MIN_VERSION);

    if (flywayMinVersion != null) {
        Flyway flyway = new Flyway();
        try {
            flyway.setDataSource(createDataSource());
            flyway.setTable(FlyWayProperty.getInstance().getProperty(FlyWayProperty.FLYWAY_MIGRATION_TABLE_NAME));
            flyway.setBaselineVersionAsString(FlyWayProperty.getInstance().getProperty(FlyWayProperty.FLYWAY_BASELINE_VERSION));
            flyway.setSqlMigrationSeparator(FlyWayProperty.getInstance().getProperty(FlyWayProperty.FLYWAY_MIGRATION_SEPARATOR));
            flyway.setEncoding(FlyWayProperty.getInstance().getProperty(FlyWayProperty.FLYWAY_ENCODING));
            flyway.setSchemas(FlyWayProperty.getInstance().getProperty(FlyWayProperty.ORACLE_DB_USERNAME));
            flyway.setBaselineOnMigrate(true);
            flyway.migrate();
            flywayMigrateStop();
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage(), e);
        }
    }
}

【问题讨论】：

需要更多信息。
什么不工作？这些日志声明表明 Flyway 认为不需要迁移。 18:43:30,945 INFO [stdout] (ServerService Thread Pool -- 14) 2017-09-19 18:43:30 INFO DbMigrate:44 - Schema "TEST_SERVER" is up to date. No migration necessary.
我添加了一些信息
@BobKuhar 有两个脚本没有执行。该方案完全是空的。

【解决方案1】：

Flyway 找不到您的迁移文件，因此它认为一切都是最新的：

INFO  DbValidate:44 - Successfully validated 0 migrations (execution time 00:00.018s)

您需要指定一个位置或将您的迁移移动到它已经在搜索的位置。使用setLocations() 这样做。

【解决方案2】：

如果您使用 maven 构建此 jar - flyway-1.0-SNAPSHOT.jar，请确保 src/main/resources 有一个包含您的 V1__20170918_Initial_structure.sql 的 db/migration 文件夹

如果它能够解决您的问题，请告诉我。
