Jersey-Spring #Autowired not working - spring

Question

I'm using Jersey-Spring integration to expose business layer services.
In my web.xml I'm using the SpringServlet:
com.sun.jersey.spi.spring.container.servlet.SpringServlet
My business layer is #Component annotated, so I have #Service's using #Repository's provided via Spring's annotation config.
Repository's are provided to service's via #Autowired annotation.
If I use a repository through a service using my front end MVC classes everithig goes well, but if I use it through Jersey I get a NullPointerException on the repository object.
The version I'm using (through Maven) are:
Spring (and extensions): 3.1.3.RELEASE
Jersey (and extensions): 1.17

Answer 1

There is way to solve this problem using the same version mentioned in your question,
If needed ill mention the second way , the first way is to load sring through web.xml
like shown below as normal spring confifuration:
<servlet>
<servlet-name>project-spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:project-spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>project-spring</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
Now load your jersey Resources through Application as shown below:
#ApplicationPath("/rest")
public class ResourceLoader extends Application
{
/* (non-Javadoc)
* #see javax.ws.rs.core.Application#getClasses()
*/
#Override
public Set<Class<?>> getClasses()
{
Set<Class<?>> classes = new HashSet<Class<?>>();
loadResourceClasses(classes);
return classes;
}
private void loadResourceClasses(Set<Class<?>> classes)
{
classes.add(StudentResource.class);
}
}
Then in your resource:
#Path("student")
class StudentResource
{
private StudentService studentService;
StudentResource(#Context ServletContext servletContext)
{
ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);
this.transactionService = applicationContext.getBean(StudentService .class);
}
}
There'r you go Spring has been configured with all dependency injections with Jersey!!!

Answer 2

You should try using #InjectParam
