Dao.createOrUpdate介绍

[英]This is a convenience method for creating an item in the database if it does not exist. The id is extracted from the data parameter and a query-by-id is made on the database. If a row in the database with the same id exists then all of the columns in the database will be updated from the fields in the data parameter. If the id is null (or 0 or some other default value) or doesn't exist in the database then the object will be created in the database. This also means that your data item must have an id field defined.

NOTE: This method is synchronized because otherwise race conditions would be encountered if this is used by multiple threads.
[中]这是一种方便的方法，用于在数据库中创建不存在的项。从数据参数中提取id，并在数据库中按id进行查询。如果数据库中存在具有相同id的行，则数据库中的所有列都将从数据参数中的字段更新。如果id为null（或0或其他默认值）或数据库中不存在，则将在数据库中创建该对象。这也意味着您的数据项必须定义一个id字段。
注意：此方法是同步的，因为如果多个线程使用此方法，则会遇到竞争条件。
