org.hibernate.boot.Metadata类的使用及代码示例

本文整理了Java中org.hibernate.boot.Metadata类的一些代码示例，展示了Metadata类的具体用法。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。Metadata类的具体详情如下：
包路径：org.hibernate.boot.Metadata
类名称：Metadata

Metadata介绍

[英]Represents the ORM model as determined from all provided mapping sources. NOTE : for the time being this is essentially a copy of the legacy Mappings contract, split between reading the mapping information exposed here and collecting it via InFlightMetadataCollector
[中]表示根据所有提供的映射源确定的ORM模型。注意：目前这基本上是遗留映射契约的副本，分为读取此处公开的映射信息和通过InFlightMetadataCollector收集信息

代码示例
