我不知道为什么所有变更集都无法执行并反映在数据库中。
我也提到了这个link,不幸的是,它也有相同的问题,对此post没有答案。
总而言之,尚未执行任何变更集,并且我的数据库中没有表(DATABASCHANGELOG除外)。
请参考以下代码。
类“ DataVersioningController.java ”具有main方法,并调用了“ liquiebaseRun()”方法。
public static void main(String args[]) throws LiquibaseException, SQLException {
new DataVersioningController().liquiebaseRun();
}
public void liquiebaseRun() throws SQLException, LiquibaseException {
JdbcConnection jdbcConnection = new JdbcConnection(DataVersioningController.getConnection());
DatabaseChangeLog dbChangeLog = new DatabaseChangeLog("D:\\ChangeSet.xml");
Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(jdbcConnection);
ClassLoaderResourceAccessor classLoaderAccessor = new ClassLoaderResourceAccessor();
CommandLineResourceAccessor clAccessor = new CommandLineResourceAccessor(getClass().getClassLoader());
CompositeResourceAccessor ref = new CompositeResourceAccessor(new ResourceAccessor[] { clAccessor, classLoaderAccessor });
database.setDefaultSchemaName("test");
database.setLiquibaseSchemaName("test");
Liquibase liquibase = new Liquibase(dbChangeLog, ref, database);
liquibase.update(new Contexts("test"), new LabelExpression());
System.out.println("Completed ");
}

您不需要手动调用liquibase。 如果您使用的是SpringBoot和Maven,则添加该依赖项:
<!-- https://mvnrepository.com/artifact/org.liquibase/liquibase-core -->
<dependency>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-core</artifactId>
<version>3.6.2</version>
</dependency>
,然后将该属性添加到您的application.properties:
spring.liquibase.change-log=//path to your changeset
