Writing Junit Tests for my spring application. Because I am new at this I tried starting off by writing a Unit Test for a DAO class that I know works (ran it in JBoss). However, I cannot get it to work as a Unit Test in Eclipse. I keep getting an "Error creating bean... Could not autowire field: NoSuchBeanDefinition".
I saw errors similar to this on StackOverflow and other sites and it always ended up being a syntax error or attempting to autowire the Implementation of the interface as opposed to the Interface, etc. I don't see any of those errors with my code.
I did download Spring-test.jar separately from the Spring configuration that came with the project. Both are from Spring 2.5 however, so I don't think that should be an issue :/
Eclipse comes bundled with JUnit 4.8 and Spring Unit Test doesn't work with that so I downgraded my JUnit to use 4.4
One thing to consider... if you look at the code for my Unit Test you will notice that I autowire two fields: a SimpleJdbcTemplate at the Query Service I want to test. Well if I remove the DrugDao and all references to it, then the SimpleJdbcQuery auto-wires just fine.
Here is the stacktrace for your review:

My mistake: there was another Spring Configuration file referenced elsewhere that I missed. Adding this field and defining setters in my Unit Test for any autowired fields solved the problem.
I am using this checklist now when these types of errors occur:
Make sure that implementing class of Interface type uses “#Service”
annotation
Make sure beans are configured properly in the XML:
Simplest way is to use:
<context:component-scan base-package="com.customization.packagename" />
This adds all classes under the package name
Or create XML Bean Definitions
I had the similar issue and found that while I could AutoWire classes successfully in Eclipse, surefire required only interfaces to be AutoWired. Especially this occurs only when using Cobertura for instrumenting, so pretty sure there is something wrong with the proxy generation. For now, I have just introduced a new interface as it was appropriate for my use-case but there should definitely be another appropriate solution.
Add a bean definition of type SpringJdbcDrugQuery to common-test.xml
I encounter this problem too, and I just add setter, then it works well.

I thought about the cause of the error, but I think it is because I did not insert the service annotation.
However, there is no typos in any way, and everything is written correctly and errors occur. Is there something I don't know?
Can you tell me what caused this error?
And what about the solution?
make sure that AdminDao bean is creating and injecting correctly into
AdminServiceImple
use this tag in your spring-cfg.xml file
<context:component-scan base-package="dao" />
and also scan the controller class using --
<context:component-scan base-package="controller" />
you have to give information of class which are going to use annotation to IOC container to create bean...
A mapper is registered to Spring by including a MapperFactoryBean in your XML config file like follows:
<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="org.mybatis.spring.sample.mapper.UserMapper" />
<property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>
try this to scan your Service Package and Dao Package.
<context:component-scan base-package="dao, service" />
above code will scan the dao and service package respectively.
I am trying DI with autowiring and I came across #Qualifier annotation annd tried the following code:
Car.java
package beans;
import org.springframework.beans.factory.annotation.Autowired;
//import org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor;
import org.springframework.beans.factory.annotation.Qualifier;
public class Car {
#Autowired
#Qualifier("e1")
private Engine engine;
// no need to have setter or constructor
public void showData(){
System.out.println("Engine Model Year : "+engine.getModelyear());
}
}
Engine.java
package beans;
public class Engine {
private String modelyear;
public void setModelyear(String modelyear) {
this.modelyear = modelyear;
}
public String getModelyear() {
return modelyear;
}
}

what's wrong in this I think the syntax is correct is there any problem with version
I am using eclipse Oxygen
You just need to add <context:annotation-config /> in your spring.xml. Certain spring annotations are not activated unless this is added. In your case, spring is not reading the #Qualifier annotation without the <context:annotation-config />.
I have tested by adding this and it seems to work.
Update:
Your spring xml needs to have the spring schema for that to detect <context:annotation-config>. Your final xml looks like this.

this is my dao class.

private SessionFactory sessionFactory;
public EmployeeDaoImpl(SessionFactory sessionfactory){
this.sessionFactory=sessionfactory;
}
#Override
public List<Employee> getEmployeeDetails() {
return getHibernateTemplate().find("from Employee");
}
}
Here another class employeeBo is calling the employeeDaoImpl.
when I run thisI am getting the below exception.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeBo' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Cannot resolve reference to bean 'employeeDao' while setting bean property 'employeeDao'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeDao' defined in ServletContext resource [/WEB-INF/spring/EmployeeBean.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: 'sessionFactory' or 'hibernateTemplate' is required
Can anybody help to resolve this. I have tried a lot and google it as well.But did get the solution.
If you have two configuration files, you duplicates 'sessionFactory' definition. Remove one of the 'sessionFactory' definitions . You would have got duplicate bean definition exception before the IllegalArgumentException.
Edit: After your comment,
public class EmployeeDaoImpl extends HibernateDaoSupport implements EmployeeDao {
public EmployeeDaoImpl(SessionFactory sessionfactory){
setSessionFactory(sessionfactory);
}
#Override
public List<Employee> getEmployeeDetails() {
return getHibernateTemplate().find("from Employee");
}
}
or get rid of constructor in above code and inject 'sessionFactory' using setter injection.See org.springframework.orm.hibernate3.support.HibernateDaoSupport.setSessionFactory(SessionFactory). I prefer later approach.
I think the problem is the type of SessionFactory you are injecting in EmployeeDaoImpl does not match with the type of the SessionFactory you used in the class.
Can you check it?
This is an old question so must be solved now but still if someone comes across this problem. Following is solution.
You can use Hibernate DAO Support by extending HibernateDAOSupport class and overriding its afterPropertiesSet() method.
This method is called in HibernateDAO support and at that time since sessionFactory is null it is throwing this error. In your custom class you can set this property explicitly and then call the same method of Parent Class (i.e. HibernateDAOSupport's addProperties() method)
package com.techcielo.spring4.hibernate.template;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Component;
#Component("hibernateTemplate")
public class Hibernate4CustomTemplate extends HibernateTemplate{
#Autowired(required=true)
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
System.out.println("Setting SessionFactory");
this.sessionFactory = sessionFactory;
super.setSessionFactory(sessionFactory);
}
#Override
public void afterPropertiesSet() {
System.out.println("Checking if properties set..."+this.sessionFactory);
setSessionFactory(sessionFactory);
super.afterPropertiesSet();
}
}
Following can be used for sample!
I had the same problem and fix it by using Autowired constructor with EntityManagerFactory. Keyur answer is correct
#Service
class EmployeeDaoImpl #Autowired constructor(
factory: EntityManagerFactory
) : HibernateDaoSupport(), EmployeeDao {
init {
if (factory.unwrap(SessionFactory::class.java) == null) {
throw NullPointerException("factory is not a hibernate factory")
}
setSessionFactory(factory.unwrap(SessionFactory::class.java))
}
...

can anybody help me telling where i am doing wrong or if i am missing any required jar file.
Your configuration for the UrlBasedViewResolver is incomplete. The exception states that the property ‘viewClass‘ is missing. For example a complete configuration:
<bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="prefix" value="/jsp/"/>
<property name="suffix" value=".jsp"/>
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"/>
</bean>
faces-config.xml
- org.springframework.web.jsf.DelegatingVariableResolver
applicationContext.xml
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven />
<context:component-scan base-package="com.test"/>
index.xhtml
<h:outputText value="#{authBean.val}"/>
AuthBean.java
package com.test.ui;
#Component
#Scope("session")
public class AuthBean {
#Getter #Setter private String val;
#Transactional public void test(){} //works fine if #Transactional is removed
Works fine,but when a method is annotated with #Transactional,the below error occurs
16:23:13,906 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/jbtst].[Faces Servlet]] (http-localhost-127.0.0.1-8080-1) Servlet.service() for servlet Faces Servlet threw exception: javax.el.PropertyNotFoundException: /index.xhtml #14,49 value="#{authBean.val}": The class '$Proxy28' does not have the property 'val'.

Using spring-3.1, hibernate3
When you use #Transactional Spring creates a proxy that implements the same interface as your class, but your AuthBean class doesn't implement an interface.
The easiest way to fix this would be to define an interface with the val property and have AuthBean implement that interface, the proxy will then also have the val property.
This helps annotation equivalent of <aop:scoped-proxy>
<context:component-scan base-package="com.test" scoped-proxy="targetClass" />
