求大神，报错org.hibernate.hql.ast.QuerySyntaxException

Question

项目用的是jpa+hibernate+spring做的，然后我写了个单元测试，运行报错
java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: LsmpOssSetting is not mapped [SELECT t FROM LsmpOssSetting t ]以下是相关代码

Answer 1

求大神解答，实在是找不到哪里错了，中文 英文网站都搜了个遍，基本上都是在说select后面跟的entity书写有误，这个例子里没有写错。可是还是报not mapped 

Answer 2

 <persistence-unit name="lsmp-oss" transaction-type="RESOURCE_LOCAL">
 <class>com.newcosoft.lsmp.oss.mode.po.LsmpOssSetting</class>
    </persistence-unit>加上这一句看看。

Answer 3

谢谢大神，加上这句是可以的，不过我在applicationContext.xml定义了这么一句扫描
<property name="packagesToScan" value="com.newcosoft.lsmp.oss.mode.po"/>  不是有了这句扫描就不需要在persistence.xml列出entity了吗？

Answer 4

<property name="packagesToScan" value="com.newcosoft.lsmp.oss.mode.po"/> 这个应该是
<property name="packagesToScan">
<list>
<value>com.newcosoft.lsmp.oss.mode.po.**.*</value>
</list>
</property>

Answer 5

试了下，不对，entity是放在po这个包里的

Answer 6

试了下，不对，entity是放在po这个包里的好像测试的时候，就要像我第一种那种写法才行。

Answer 7

试了下，不对，entity是放在po这个包里的好像测试的时候，就要像我第一种那种写法才行。 
感谢你，现在知道问题出在packagesToScan，我继续在网上找解决办法吧

Answer 8

问题找到了
     <property name="packagesToScan" value="com.newcosoft.lsmp.oss.mode.po"/>         <property name="persistenceXmlLocation" value="src/main/resource/persistence.xml" /> 
问题出在persistence.xml上，我把它和spring配置文件放到了一起，因为persistence.xml文件的影响，导致packagesToScan这个属性无法正常工作，无法再去扫描entity，所以会报is not mapped
