[Issue] JUnit & SpringIOC

[paulsjv]

Hi,

I'm fairly new to Spring and we are currently using Spring's IOC functionality. I'm responsible for creating an ant build that will run our JUnit tests. However, these test run fine in our IDE (Eclipse) but when I run them using the junit ant task I get the following error:

[junit] junit.framework.TestListener: addError(findByCategoryName, Error creating bean with name 'com.wfm.p3.model.finder.ItemGroupFinderTest': Injection of resource fields failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefini tionException: No unique bean of type [com.wfm.p3.model.ItemGroupHome] is defined: Unsatisfied dependency of type [class com.wfm.p3.model.ItemGroupHome]: expected at least 1 matching bean)

We are using JUnit 4.4 and consequently using the @ContextConfiguration annotation.

@ContextConfiguration(locations={"/testContext.xml"})

The code seems to find the testContext.xml file just fine but for some reason doesn't do the injection.

Please let me know if you have any suggestions as to next steps because I'm pretty much lost. Also, since I'm new to this please let me know if I need to provide any other information that will help in resolving this issue.

Thanks!

Just a few quick questions to help diagnose your problems:

1. What version of Ant are you using?
2. What does your /testContext.xml file look like?
3. What does your test class look like?

For the latter two questions, feel free to just include the relevant parts.

regards,

Sam

Hi Sam,

Thanks for the response!

Question 1: Ant version 1.7.0

Question 2: We are doing a hack of sorts. Please let me know if you need further clarification.

	<import resource="applicationContext.xml"/>

	<!-- 
	
		HACK!   Override 'dataSource' here by executing a jndi-lookup which will fail and return the default 'p3basicDataSource'
				Note:  This *must* come after the import for 'applicationContext.xml'.  The XML files are parsed first, and 
				subsequent jndi-lookups with the same id replace previously parsed definitions.
	
	 -->	
    <bean id="p3basicDataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"/>
        <property name="url" value="jdbc:oracle:thin:@host:1521:db"/>
        <property name="username" value="**"/>
        <property name="password" value="**"/>
    </bean>
    
	<jee:jndi-lookup id="dataSource" jndi-name="java:comp/env/jdbc/p3" default-ref="p3basicDataSource"/>

Question 3:

package com.wfm.p3.model.finder;


import java.lang.reflect.Method;
import java.util.List;

import javax.annotation.Resource;
import javax.persistence.JoinColumn;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import com.wfm.p3.model.ItemGroup;
import com.wfm.p3.model.ItemGroupHome;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/testContext.xml"})
public class ItemGroupFinderTest {

	@Resource
	private ItemGroupHome home;

	@Test
	public void findByCategoryId() {
		Assert.assertNotNull(home);

		ItemGroupFinder finder = new ItemGroupFinder();
		finder.setCategoryId(new Long(3));
		
		List<ItemGroup> list = home.find(finder);
		Assert.assertNotNull(list);
		for(ItemGroup ig: list)
			System.out.println(ig.getGroupDescription());
	}
	
	@Test
	public void findByCategoryName() {
		Assert.assertNotNull(home);

		ItemGroupFinder finder = new ItemGroupFinder();
		finder.setCategoryName("Produce");
		
		System.out.println("go find Produce groups");
		List<ItemGroup> list = home.find(finder);
		Assert.assertNotNull(list);
		for(ItemGroup ig: list)
			System.out.println(ig.getGroupDescription());
	}
}

Well we've narrowed it down to hibernate. Apparently, the table processing/mapping isn't happening. The applicationContext.xml is getting loaded and in it we have the following xml so that the model classes should get processed. So now we need to figure out why the processing isn't happening. Any ideas?

applicationContext.xml

<context:component-scan base-package="com.wfm.p3.model"/>
