PackageToScan使用详解【Spring集成Hibernate时使用annotation形式的pojo对象时的映射类的扫描问题】

I am doing the same thing and ran into the same problem. As far as I can tell packagesToScan will take a list of packages and only scan for entities in those packages, not subpackages.

I did have some success with the wildcard "*". Using an example class structure I will explain what I saw and what my solution was:
com.model.Entity1
com.model.Entity2
com.model.foo.Entity3
com.model.bar.Entity4
com.model.foo.bar.Entity5
com.model.bar.foo.Entity6

My solution for this structure was:
<property name="packagesToScan">
<list>
<value>com.model</value>
<value>com.model.*</value>
<value>com.model.*.*</value>
</list>
</property>

com.model would find Entity1 and Entity2 and only those entities
com.model.* would find Entity3 and Entity4 and only those entities
com.model.*.* would find Entity5 and Entity6 and only those entities

I haven't looked at the source code. I thought it would just be easier to play with it and see what it does. 

I think it would be nice if you could specify a .** to recurse through all subpackages. I don't know if the * is getting expanded by whatever parses the config or if the AnnotationSessionFactoryBean is supporting this.

 

Hi drob,

thanks a lot for your answer. I think I found a solution, at least in my case. I just use this syntax:

Code:

<property name="packagesToScan">
	<list>
		<value>de.moose.r2.domain.**.*</value>
	</list>
</property>

Now every entity-class, even in sub-packages, will be found by spring.

Hope that helps

<!--
    packagesToScan的路径配置要比实际的少一层，
    此处的pojo放在cn.com.easykm.commonkey.entity包里面
    但是配置的却是cn.com.easykm.commonkey.*
-->
<list>
    <value>cn.com.easykm.commonkey.*
    </value>
</list>
