我有一个使用Spring HATEOAS的Spring Boot应用程序,它启用了@EnableEntityLinks.该应用程序有一个mvc控制器,包含一个字段@Autowired EntityLinks entityLinks.
我希望@EnableEntityLinks提供EntityLinks bean(根据：Exposing and Managing Links with Spring HATEOAS),但我得到NoSuchBeanDefinitionException：找不到类型为[org.springframework.hateoas.EntityLinks]的限定bean
该应用程序是一个测试应用程序,因此它非常小：
Application.java：
@ComponentScan
@EnableAutoConfiguration
@EnableEntityLinks
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
}
CustomerController：
@Controller
@ExposesResourceFor(Customer.class)
@RequestMapping(value = "/customers",produces = "application/json")
public class CustomerController {
@Autowired
private EntityLinks entityLinks;
@RequestMapping(method=RequestMethod.GET)
@ResponseBody
public ResponseEntityCustomer.java
public class Customer extends ResourceSupport {
private Long id;
private String firstName;
public Customer(Long id,String firstName) {
this.id = id;
this.firstName = firstName;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
}
的pom.xml
