我将Spring用于IoC和数据JPA支持,RESTEasy实现提供了JAX-RS支持。

我有两个资源:
父母:
@Component
@Path("/parent")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class ParentResource {
@Context
ResourceContext resourceContext;
@GET
@Path("sub")
public ChildResource getSub() {
return resourceContext.getResource(ChildResource.class);
}
}
孩子:
@Component
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class ChildResource {
@Autowired
Repository1 repository1;
}
此示例完全与Jersey实现配合使用,我可以从子资源获取存储库,但是在RESTEasy实现中,它不起作用,并且代替存储库实例,为空。
有一个解决方法,如下所示:
ChildResource resource = resourceContext.getResource(ChildResource.class);
resource.setRep(repositoryFromParent);
return resource;
但这很丑陋,不应该那样做(父母也应该知道子资源的所有依赖关系,这也不是件好事。)
是否有人在使用Spring和RESTEasy一起处理子资源时遇到相同的问题?
