Hibernate/JPA在启动时未针对数据库模式进行验证 [英] Hibernate/JPA not validating against DB schema on startup

问题描述

出于某种原因，休眠状态无法捕获诸如将实体映射到不存在的表之类的问题.我的persistence.xml文件看起来像这样...

For some reason hibernate is not catching issues like mapping entities to tables that do not exist. My persistence.xml file looks like this...

<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
        http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">

推荐答案

尝试添加值为"validate"的属性"hibernate.hbm2ddl.auto":

Try adding the property "hibernate.hbm2ddl.auto" with value of "validate":

<property name="hibernate.hbm2ddl.auto" value="validate"/>
