Lazy fetching should almost always be used as your default association-fetching strategy.

This code overrides the default lazy fetching strategy for the employee's address association.
这个调用覆盖职员地址关联默认的惰性抓取策略。
Although lazy fetching should be the primary fetching strategy for most applications, it does add a few complications.
尽管惰性抓取应该作为大多数应用程序的主要抓取策略，但是它增加了复杂性。
By default, if lazy fetching is used, 11 queries will be executed - one for the list of employees and one for each employee's address.
如果使用惰性抓取，在默认情况下将执行11个查询—执行一个查询获取职员的列表，然后为获取每个职员的地址各执行一次查询。

Another issue with lazy fetching is that the database connection has to be retained until all the required data is fetched else the application will throw a lazy loading exception.
延迟抓取的另一个问题就是在获取到请求的数据前要一直打开数据库连接，否则应用就会抛出一个延迟加载异常。
Unless you have a legacy table that has many columns you don't need, this fetching strategy usually can't be justified since it involves extra SQL for the lazy property group.
