谁能建议我在这里做错了什么？
【问题讨论】：
上面写的很清楚：Table 'testspring.user' doesn't exist.
您在名为 testspring 的数据库中没有名为 user 的表。
如果不存在，hibernate不应该第一次在数据库中创建表吗？
@codeFish 您需要为 hibernate.hbm2ddl.auto=update 或 create 添加配置。
我正在使用休眠注释。这还不够吗，还是我必须为每个数据库 pojo 类纠正每个配置文件？
【参考方案1】：
如果表确实存在于 mySQL 中，并且您使用的是 Linux/Unix，并且错误显示表名全部错误/大写，那么问题是 MySQL 中的表名区分大小写并且hibernate 是大写它们。我正在使用休眠 4.3。
我刚遇到这个问题。此处解释：lower_case_table_names=1
--edit-- 回想起来，最好找到并更改任何 @Table 或 hbm.xml 引用以匹配数据库。我运行了一个生成带有大写名称的 hbm.xml 的向导——直到现在才意识到它在我的项目中。我将把它留在这里，让人们意识到区分大小写。
--编辑结束--
这是我修复它的方法：
-
删除数据库。
将此添加到 /etc/mysql/my.conf：
set lower_case_table_names=1 #(default value '0').
【讨论】：
【参考方案2】：Hibernate 不会自动为您生成数据库架构。您必须使用特殊的休眠属性告诉它这样做：
hibernate.hbm2ddl.auto
值update 或create 取决于你想要什么。 See here and the related chapters.
在 Spring 中，配置进行
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">$jdbc.dialect</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
