本文整理了Java中javax.persistence.Query.getMaxResults方法的一些代码示例，展示了Query.getMaxResults的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Query.getMaxResults方法的具体详情如下：
包路径：javax.persistence.Query
类名称：Query
方法名：getMaxResults

Query.getMaxResults介绍

[英]The maximum number of results the query object was set to retrieve. Returns Integer.MAX_VALUE if setMaxResults was not applied to the query object.
[中]查询对象设置为检索的最大结果数。如果setMaxResults未应用于查询对象，则返回Integer.MAX_VALUE。
