  • Problem with Autowiring

    Hi All,

    I am facing below issue when using Spring with Junit4.x.

    Code:

    Actually my problem is i have different web projects in my project hierarchy like Controllers in one project,service layer in another and dao layer in another project.

    I am using Annotations when i deploy all as a Ear, my application is working fine but when i run the same through Junit test case iam getting above exception.

    Below is the part of code for the Junit test class

    Code:
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations = { "springMVC-service.xml",
    		"springMVC-servlet.xml" })
    public class EcpProductionControllerTest {
    
    	@Autowired
    	ECPProductionController ecpProductionController = null;
    	
    	public void setEcpProductionController(
    			ECPProductionController ecpProductionController) {
    		this.ecpProductionController = ecpProductionController;
    	}
    SpringMVC-Servlet.xml

    Code:
    	<context:annotation-config />
    	<context:component-scan base-package="com.fritolay.suppliernet.ecp.web.controller" />
    
    	<bean
    		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    	</bean>
    As per my assumption,it is not able to wire from different pkg..Please let me know how to overcome this issue.
Working...
