使用Hibernate Criteria API阅读

Question

I'm using Hibernate Criteria API in my project. In this API, list() method is used to get a number of records from db. My question is : How to get only one record from db (without using list() method as there is no need)?

Answer 1

If you're certain that the query is going to return at most one record, use Criteria#uniqueResult() .

If the query can return more than one record, but you're fine with just getting the first result, you could combine uniqueResult() with Criteria#setMaxResults() .
