If the bean ( PartnershipService ) is Normal bean then you can use @Component
If the bean (PartnershipService ) is service bean ( Service layer ) then you can use @service

Information about @Component, @Service, @Controller, and @Repository annotation do in Spring Framework:
@Component is a generic stereotype for any Spring-managed component or bean.
@Repository is a stereotype for the persistence layer.
@Service is a stereotype for the service layer.
@Controller is a stereotype for the presentation layer (spring-MVC).

The error messages says:

Could not autowire field: com.cgi.bkifs.bso.prime.partnership.maintainence.service.PartnershipService

Assuming that you already declared a class PartnershipService and it has the @Service annotation it is likely that you did not define the component scan.

Either add

@ComponentScan(basePackages = "com.cgi.bkifs.bso.prime.partnership") or in older versions use the xml file to define the scope of component scan:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

     <context:component-scan base-package="com.cgi.bkifs.bso.prime.partnership"/>

</beans>

Probably you forgot to making PartnershipService as Spring Bean.

   @Component
   public class PartnershipService{}
