刚刚学hibernate，总是出现问题。现在给大家一些建议，免得浪费时间，在那里不停的调啊，调啊。
关键字 'user' 附近有语法错误
GetGeneratedKeysDelegate.executeAndExtract(IdentityGenerator.java:73)

注意你的数据库名字是不是与user有关，user貌似是数据库什么的关键字，不能用关键字。我的数据库名字用了user-addr，并且某个*.hbm.xml文件用了如下写法
<hibernate-mapping>
<class name="com.h1.dao.Client" table="client" schema="dbo" catalog="user- addr">
...
是配置文件写错啦，用了关键字
注意user不能用（会报错，关键字 'user' 附近有语法错误）， - 也不能用（会报错，'-' 附近有语法错误。）。
