ormlite保存大量数据性能优化

原来是这样写的：

public void addList(List<AreaBean> areas) {
    try {
        for (AreaBean area : areas){

 areaDao.createOrUpdate(area);

} } catch (Exception e) { e.printStackTrace() ; }} 3000多条数据，耗时大概30秒

后来改成

try {
    DatabaseConnection conn = areaDao.startThreadConnection();
    Savepoint savePoint = conn.setSavePoint(null);
    for (AreaBean area : areas){
        areaDao.createOrUpdate(area);
    }
    conn.commit(savePoint);
    areaDao.endThreadConnection(conn);
} catch (Exception e) {
    e.printStackTrace();
}

大概1秒之内就写入了
