hi all:
The following code is my model class. Specially, the key
property
"regionId" is a String, not a Long type.
When I use "mvn appfuse:gen -Dentity=DRegion " to generate all the
code and
run "mvn integration-test",
there is an Excepion :
java.lang.NullPointerException
at com.huaat.webapp.action.DRegionAction.list(DRegionAction.java:
38)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at
sun.reflect.NativeMethodAccessorImpl.invoke
(NativeMethodAccessorImpl.java:39)
................
..........
Then I check the code DRegionAction.java in line 38: dRegions =
dRegionManager.getAll();
Obviously , the dRegionManager is NULL ! I check every config
files ,
the dRegionManager bean
was added correctly, including in applicationcontext.xml. like
this:
<!--DRegionManager-START-->
<bean id="dRegionManager"
class="org.appfuse.service.impl.GenericManagerImpl"
autowire="byName">
<constructor-arg>
<bean
class="org.appfuse.dao.hibernate.GenericDaoHibernate">
<constructor-arg
value="com.myproject.model.DRegion"/>
<property name="sessionFactory"
ref="sessionFactory"/>
</bean>
</constructor-arg>
</bean>
<!--DRegionManager-END-->
now the question is, why the dRegionManager is not injected in my
DRegionAction ?
and why every thing is ok when the model key property chang to
Long,
instead of a String ?
thanks advanced!
