저는 JAX-RS를 처음 사용하고 Embedded Tomcat을 사용하는 데 어려움을 겪고 있습니다. 아래Jersey와 Jackson을 사용하여 JSON으로 모델을 반환하려고 할 때 내부 서버 오류가 발생했습니다.
- 코드는 작동 : http://yourhost.me:8080/rest/resource/hello
- 하지만 난은 "내부 서버 오류"를 얻을 : http://yourhost.me:8080/rest/resource/car
누구나/자동차 URI가 작동하려면 내가 부족을 확인? JSON으로 응답을 얻으려고합니다. 또한 spring-hateoas를 사용하여 링크를 얻으려면 아래에서 어떻게 업데이트 할 수 있는지 아는 사람이 있습니까? Tomcat이 아닌 비 Jersey 프로젝트에서 스프링 - hateoas 링크가 작동하지만이 설정으로 작동시키지 못합니다. 톰캣에 대한

ResourceLoader.java 독립 Tomcat을 실행 - 난 곳 여기 것은 리소스 등록 중
package com.sample.resources;

public class ResourceLoader extends Application {
@Override
public Set<Class<?>> getClasses() {
final Set<Class<?>> classes = new HashSet<Class<?>>();
// register root resource
classes.add(HelloWorldRestResource.class);
return classes;
}
}
HelloWorldRestResource.java - 각 URI를 처리 할 수있는 컨트롤러/안녕하세요/자동차

@XmlRootElement()

public Car(int year) {
