在休眠启动时删除所有表 [英] Drop all tables at hibernate startup

问题描述

出于开发目的，如何配置休眠方式使其在运行之前删除所有表?我不想在运行代码之前不断手工删除所有表.

How can I configure hibernate in a way that it DROPS all tables before it runs, for developement purposes? I don't want to constantly DROP all tables by hand before running my code.

我已经在使用

<property name="hbm2ddl.auto">create</property>

但这似乎不起作用，因为我遇到了一些错误，这些错误是由先前运行中的错误模式引起的.

But this does not seem to work, since I ran into several errors that where caused by wrong schemas from a previous run.

修改 也许我的问题有点误导.我想要一个干净的数据库.这不仅是因为实际的运行时错误，而且还因为每次运行都拥有一个干净的数据库.

Edit Maybe my questions was a bit missleading. I want to have a clean database. Its not only because of actual runtime errors but also about having a clean database for every run.

<property name="hbm2ddl.auto">create-drop</property>

忽略无法休眠的表(如果您正在使用表名，这种情况可能会经常发生).

Ignores tables that are unknown to hibernate (which can happen quite often if you are playing around with tablenames).

推荐答案

使用值create-drop代替create
