【问题描述】：
我正在尝试在 Camel 应用程序中将 Spring Data JPA 与 Hibernate 一起使用，但无法确定依赖关系 - 我遇到的问题是尝试注入 Spring Data JPA Repository 对象时；
org.springframework.beans.factory.BeanCreationException：创建名为“personRepository”的bean时出错：bean初始化失败；嵌套异常是 java.lang.AbstractMethodError。
根据我所做的研究，我认为这是由于依赖性问题，所以我想确保我为 Camel、Spring、Spring Data JPA 和 Hibernate 准备了正确的版本。
我错过了什么？

提前致谢！

编辑：personRespository 对象应该被注入到我的 ListCaseNotes 对象中，这又是我骆驼路线的目标；
RouteBuilder：
@Component
public class VisitsRouteBuilder extends RouteBuilder {
@Autowired
private ListCaseNotes listCaseNotes;
@Override
public void configure() throws Exception {
from("direct:visits")
// route based upon the method being invoked
.choice()
.when(header(Constants.METHOD_NAME).isEqualTo("listCaseNotes"))
.unmarshal().json(JsonLibrary.Jackson, ListNotesKey.class)
.bean(listCaseNotes)
.end()
// marshal the returned pojo to JSON
.marshal()
.json(JsonLibrary.Jackson);
}
}
列表案例说明：
@Service
public class ListCaseNotes extends InterfaceHandler {
private final PersonRepository personRepository;
private final CaseRepository caseRepository;
public ListCaseNotes(PersonRepository personRepository, CaseRepository caseRepository) {
System.out.println("ListCaseNotes()");
this.personRepository = personRepository;
this.caseRepository = caseRepository;
}
...
PersonRepository：
@Repository
public interface PersonRepository extends CrudRepository<Person, Long> {
}
编辑：完整的堆栈跟踪如下；

【问题讨论】：
-
显示完整的异常堆栈跟踪以及您正在使用的这个 personRepository 对象在哪里？在哪个班？
-
我已经添加了完整的堆栈跟踪和有问题的类。
