TestingError: UnsatisfiedDependencyException

[JoeGranada]

Hello,
I am quite new to Spring and think its a real cool framework, but i encountered some problems during testing my Services:

I've made a general BaseClass extending "AbstractTransactionalSpringContextTests" and overwrote the method getConfigLocations with my SpringConfig.xml. This worked fine for DAOSupport, aber but now i have this UnsatisfiedDependencyException i can not understand.

Full Stack Trace:
org.springframework.beans.factory.UnsatisfiedDepen dencyException: Error creating bean with name 'com.gerig.app.test.services.AddressServiceTest' defined in null:
Unsatisfied dependency expressed through bean property 'addressService': There are 2 beans of type [class com.gerig.app.services.base.AddressService] for autowire by type.
There should have been 1 to be able to autowire property 'addressService' of bean 'com.gerig.app.test.services.AddressServiceTest'.

But i only have one bean called addressService:
<bean id="addressService" parent="transactionInterceptorTemplate">
<property name="target">
<ref bean="addressServiceTarget"/>
</property>
</bean>

the AddressServiceTarget:

<bean id="addressServiceTarget" class="com.gerig.app.services.base.AddressService">
<property name="addressDAO">
<ref bean="addressDAO"/>
</property>
<property name="lovService">
<ref bean="lovService"/>
</property>
<property name="zipCode2CityService">
<ref bean="zipCode2CityService"/>
</property>
</bean>

I don´t know the Problem. Is there any way to solve this Probem??

Thank you!

Make the target an inner bean. That is, make the contents of the "target" property value a bean definition rather than a reference.

So I changed it to:


<property name="target">
<bean class="org.gbif.col2005.service.impl.TaxaManagerImpl">
<property name="taxaDAO" ref="taxaDAO"/>
</bean>
</property>


And it got rid of the error - hope this helps someone else

Using "autoproxying" approaches--which will become more common with Spring 2.0--also avoids the duplicate bean error.

The old practice XX and XXTarget should usually be avoided in favour of the inner bean, with Spring 1.2.x also.

I am having a similar problem but moving the the "dataSource" bean into data access classes doesn't fix the problem for me. Any ideas?

Here is the error:
org.springframework.beans.factory.UnsatisfiedDepen dencyException: Error creating bean with name 'com.mycompany.user.dao.UserDaoTest' defined in null: Unsatisfied dependency expressed through bean property 'userDao': set this property value or disable dependency checking for this bean
at org.springframework.beans.factory.support.Abstract AutowireCapableBeanFactory.checkDependencies(Abstr actAutowireCapableBeanFactory.java:962)

Here is the test bean definitions:
<beans>
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName"><value>${jdbc.driverClassName}</value></property>
<property name="url"><value>${jdbc.url}</value></property>
<property name="username"><value>${jdbc.username}</value></property>
<property name="password"><value>${jdbc.password}</value></property>
</bean>

<bean id="userDao" class="com.mycompany.user.dao.jdbc.JdbcUserDao">
<property name="dataSource"><ref local="dataSource"/></property>
<property name="userGroupDao"><ref bean="userGroupDao"/></property>
</bean>

<bean id="userDaoTest" class="com.mycompany.user.dao.UserDaoTest">
<property name="userDao"><ref bean="userDao"/></property>
</bean>

<bean id="userGroupDao" class="com.mycompany.user.dao.jdbc.JdbcUserGroupDao">
<property name="dataSource"><ref local="dataSource"/></property>
</bean>
</beans>

Is the use of ref="target" only for Spring 2.0?

<bean id="jobRequestDAO"
class="com.spinsys.agent.job.dao.JobRequestDAO">
<property name="dataSource"> <ref bean="avianDS"/></property>
</bean>

that works for me in general.. but once I switched to trying to write a unit test with extends AbstractTransactionalDataSourceSpringContextTests. .. nothing works.

I get the exception mentioned at the start of this thread (that is can't find a bean to autowire but it found 4 beans etc).

I have 2 xml files application-DS.xml and application-DAO.xml.

I tried to ref="avianDS" without adding 'bean' and that fails the sax parser.

any hints?

[Oreoferret]

So.. i got it to work.. but the only means I could do so was to put the dataSource bean, as well as the daos, as well as my transaction manager.. *all in one file*.

Is there any way to have these work if my dataSource's are in an applicationDS.xml, and my DAOs are in an applicationDAO.xml. If I seperate the files, I get the 'found too many beans to autowire' problem (it seems to multiple in 2's).

Thanks
