在Java代码中运行liquibase

它应该类似于（取自liquibase.integration.spring.SpringLiquibase源代码）：

java.sql.Connection c = YOUR_CONNECTION;Liquibase liquibase = null;try {    Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(c))    liquibase = new Liquibase(YOUR_CHANGELOG, new FileSystemResourceAccessor(), database);    liquibase.update();} catch (SQLException e) {    throw new DatabaseException(e);} finally {    if (c != null) {        try { c.rollback(); c.close();        } catch (SQLException e) { //nothing to do        }    }}

ResourceAccessor有多种实现方式，具体取决于应如何找到更改日志文件。
