More than one table found in namespace (, ) :

hibernate.default_schema配置

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.connection.driver_class">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.jdbc.fetch_size">50</prop>
<prop key="hibernate.jdbc.batch_size">30</prop>
<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.cache.use_second_level_cache">false</prop>
<prop key="hibernate.hbm2ddl.auto">false</prop>
<prop key="hibernate.default_schema">SCOTT</prop>
</props>
</property>

此处hibernate.default_schema 是默认的数据库，会在hibernate发送hql语句的时候在表名称之前加上，如果不对，hql语句报错，表或者视图不存在
 

同一个oracle数据源下有多个模式，jpa在启动检查时似乎是将该数据源所有模式库下的表检查一遍，当发现不同模式下存在着相同的表名时，就会报错More than one table found in namespace (, )。
