Do not work with Spring Boot for Spring Data JPA

[jessehu]

Thanks for making this fabric-spring-sdk. It's really great.
I'm trying to use it together with org.springframework.boot:spring-boot-starter-data-jpa, but ran into bean instantiation issue.
Here is my sample Spring Boot App https://github.com/jessehu/spring-chaincode-sample. Its pom contains:

    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-chaincode</artifactId>
      <version>0.0.1-SNAPSHOT</version>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-rest</artifactId>
  </dependency>

There is a class having two autowired fields, one for Spring Data Chaincode, and the other for Spring Data JPA:

@RepositoryRestController
public class ChaincodeController {
   @Autowired
   SimpleAssetRepository simpleAssetRepo;
   @Autowired
   ChaincodeRepository ccRepo;
} 

When running this Spring Boot App in Spring STS 3.9.3, it failed to instantiate SimpleAssetRepository and threw error "Not a managed type: class java.lang.Object" as below:

If remove spring-boot-starter-data-jpa from the pom.xml, SimpleAssetRepository can be instantiated, but the Spring Data JPA class ChaincodeRepository can not be instantiated.

Please help take a look when you are free. Thanks very much.
