生成數據導出SQL文件通過Java API使用Liquibase

Question

想生成從通過Java代碼liquibase一個SQL文件複製此命令

java -jar liquibase.jar --changeLogFile="./data/filename" --diffTypes="data" generateChangeLog 

我用這作爲一個土生土長的SQL備份Java類的替代品

類似下面應該做你想要什麼，我認爲：

ResourceAccessor resourceAccessor = new FileSystemResourceAccessor(); 
Database db = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(new JdbcConnection(yourJdbcConnection)); 
Liquibase liquibase = new Liquibase("data/filename", resourceAccessor, db); 
try (Writer writer = new OutputStreamWriter(System.out)) { 
    liquibase.update((Contexts) null, writer); 
}
