I'm trying to connect MySQL database with Spring. And I also want to use DataSource setter method with #Autowired. Every time I run the code, DataSource always return as null.
Error:
HTTP Status 500 - Request processing failed; nested exception is java.lang.NullPointerException
Can someone show me whats wrong with my code? Please find below my code.

In your CustomerController class, try changing this line:
private CustomerService customerService;
to:
#Autowired
private CustomerService customerService;
or you can auto-wire it via setter or constructor injection, if you like.

Hi,
I got this error and i can`t figure why? all of the defintions in there place and still i have this error while i trying to insert data to my DB.
the "tx:annotation-driven" is in the appconfig-data.xml

What could be the reason it does not work?

You are using non transactional daos in your UserController.registration method:
roleDAO.add(roleUser);
roleDAO.add(roleAdmin);
Use RoleServiceImpl instead.
I am getting following exception,please help to resolve this ?

When I try to run this code I am getting exception that I have posted. Autowired injection is not happening. What is the problem ?
Take a close look at the Exception, It says
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.
It looks like you are not creating sessionFactory bean. Make sure you have sessionFactory added in you spring configuration
For Example :
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="${hibernate.config}"
/>
I've been using objectDB as a database in my Spring application, yet it is only free for up to 10 tables, so i've tried to migrate to MySQL. When I look into database the tables are created, but when I try to persist I get the NullPointerException. Here are my configuration files:

I am going to be confused. I am trying to get Hibernate work with Spring, I can not get rid of a BeanCreationException. Please help me. I am new to Spring (and also Hibernate).
The problem is caused in a controller, having a private attribute userService which is annotated with #Autowired.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'testController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.aerts.service.UserService com.aerts.controller.TestController.userService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.aerts.service.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}

}
#Override
#Transactional
public void updateUser(User user) {

}
}
I would really appreciate it if somebody could help me, i am going to be desperate...
Add the service class package to the component-scan base-package list in the application context file
<context:component-scan
base-package="
com.aerts.controller
com.aerts.service">
</context:component-scan>
I'm not expertise in spring but I assume that you have a problem with your service, if you use an interface you should inject ut and not your class...
see this track...
Spring expected at least 1 bean which qualifies as autowire candidate for this dependency
