Bean Creation Exception in Spring

I am Trying To autowire A Class that's declared in Another Project , But in i am getting a Run Time Exception Not a compile time Exception.If i Remove the Autowire and create an object using new Instance its perfectly running.

I am Getting the Following Error:

ErrorSEVERE: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getThreshold': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.xyz.spikedetection.service.VBDSService com.xyz.spikedetection.vbdswebservice.GetThreshold.vbdsService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.xyz.spikedetection.service.VBDSService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

This is the class from where i am calling the web-service

@RestController
public class GetThreshold  {


    private static final Logger logger = LoggerFactory.getLogger(GetThreshold.class);

    @Autowired
    private VBDSService vbdsService;



    @RequestMapping(value="/getBreaches",method = RequestMethod.POST, consumes = "application/json")
    public @ResponseBody BreachDetectionResponse getThresholds(@RequestBody SuborderData soData) throws Exception{
    /*  setupDB();
        this.dbTester.setSetUpOperation(DatabaseOperation.CLEAN_INSERT);
        this.dbTester.setDataSet(getClasspathDataFromXml("Table_sd_threshold.xml"));
        this.dbTester.onSetup();
    */  

        //vbdsService=new VBDSServiceImpl();

        return vbdsService.getBreachesForSuborder(soData);
    }

if i remove the Comment vbdsService = new VBDSServiceImpl();Its executing perfectly.

Make sure you annotate the class VBDSServiceImpl with @Service and is within the package or a subpackage of com.xyz.spikedetection.vbdswebservice since you specified it as a base-package for component scanning. Then spring will create an VBDSServiceImpl object and inject the same into vbdsService property.

If your services are in multiple packages, you can component scan the same using

<context:component-scan base-package="com.xyz.spikedetection.vbdswebservice, anotherPackage"/>

The code below will work because instead of spring container creating an object, you are creating an object of the implementation class. 

vbdsService=new VBDSServiceImpl();

There really is no bean definition for VBDSService as far as the code you posted shows. If the implementing class hasn't got any annotations that spring will recognize via context:component-scan then there is just no bean defined having that interface.

Since you commented out the creation of the VBDSServiceImpl, you probably should add a bean definition for it in your applicationContext.xml.
