Cannot bind GraphRepository Neo4j to Controller in Spring - spring

Question

I am using Spring with Neo4j lib to make REST Web application which will manipulate data on Neo4j database. I am struggling with configuration of my project I cannot manage to start it in Tomcat.
My HelloController class which is in package: com.testing.demo.neo
#Controller
#RequestMapping("/")
public class HelloController {
#Autowired
ItemRepository itemRep;
#RequestMapping(value = "/user/{id}", method = RequestMethod.GET)
public String getUser(#RequestParam int id) {
User user = userRep.findByPropertyValue("id", id);
if(user == null)
return("User is null");
else
return user.toString();
}
#RequestMapping(value = "/user", method = RequestMethod.POST)
public String addUser(#RequestBody User user) {
userRep.save(user);
return user.toString();
}
...
}
My UserRepository class which is in package: com.testing.demo.neo.repository
public interface UserRepository extends GraphRepository<User> {
}
My dispatch-servlet.xml:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"

</bean>

<neo4j:config graphDatabaseService="restGraphDatabase" />
</beans>
And my pom.xml file consists of:

When trying to deploy on Tomcat and run application I get the following error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'helloController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.testing.demo.neo.repository.UserRepository com.testing.demo.neo.HelloController.userRep; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'itemRepository': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: Ljavax/validation/Validator;
I am searching for solution for several past days and haven't managed to find it. Please if you could help me with this configuration. Thanks in advance.
EDIT:
I solved the problem by changing the spring.version to 3.1.0.RELEASE and adding following dependency to pom.xml beacuse of the Hibernate Validator which is used by Neo4j:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>

Answer 1

You are missing the below dependency
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
