Spring 2.5.5 and jersey with autowired - spring

Question

I am trying to integrate jersey to an existing Spring application (Spring 2.5.5).
Jersey is working fine, but however when I AutoWire an existing spring bean, the object is null.
Below is my web.xml
<servlet>
<servlet-name>fs3web</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.fl.fs3.api;org.codehaus.jackson.jaxrs</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>fs3web</servlet-name>
<url-pattern>/fs3/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
And, here my application context xml (obviously this is not complete, since this is a huge application, there is much more bean definitions):
TestPojo is my bean I would like to autowire to my jersey resource.
<context:annotation-config />
<aop:aspectj-autoproxy/>
<context:component-scan base-package="com.fl.fs3.api,com.fl.fs3.integration.*.web"/>
Both my jersey resource class and POJO class is in package com.fl.fs3.api
#Component
#Path("/v1/site")
public class SitesApiControllerV1 {
#Autowired TestPojo testPojo;
#GET
#Path("/{folderName}")
#Produces(MediaType.APPLICATION_JSON)
public Response getSite(#PathParam("folderName") String folderName) {
System.out.println("pojo obj:" + testPojo);
return Response.ok("info for " + folderName).build();
}
}
#Component
public class TestPojo {
}
When I start my tomcat, I do not see the expected line in logs:
INFO: Registering Spring bean, hello, of type ..... as a root resource class
When I invoke my service /v1/site/xyz, testPojo object is null.
However, before integrating this to my existing project, I did a sample jersey+spring application, and it worked perfectly. I was able to see 'Registering Spring bean' line in logs.
Any help is appreciated.

Try this, it may be more simplified:
Load spring 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 you go.
Spring has been configured with all dependency injections with Jersey!
