我是一个完整的初学者,正在学习构建一个RESTful Web服务。我想知道如何为JAX-RS中的子资源内的子资源设置路径。如何为JAX-RS中的子资源内的子资源设计路径?
我有三个资源:配置文件,消息和评论。 我想我的网址如下。
对于型材
/profiles
的消息
/profiles/{profileName}/messages
注解
/profiles/{profileName}/messages/{messageId}/comments
我的资源具有路径如下。
资料资源
@Path("/profiles")
public class ProfileResource {
@Path("/{profileName}/messages")
public MessageResource getMessageResource() {
return new MessageResource();
}
}
消息资源
@Path("/")
public class MessageResource {
@Path("/{messageId}/comments")
public CommentResource getCommentResource() {
return new CommentResource();
}
@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Message addMessage(@PathParam("profileName") String profileName, Message message){
return messageService.addMessage(profileName, message);
}
}
评论资源
@Path("/")
public class CommentResource {
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Comment postComment(@PathParam("messageId") long messageId, Comment comment) {
return commentService.addComment(messageId, comment);
}
}
,但我得到了下面的错误,
SEVERE: Servlet [Jersey Web Application] in web application [/messenger] threw
load() exception org.glassfish.jersey.server.model.ModelValidationException:
Validation of the application resource model has failed during application
initialization.
[[FATAL] A resource model has ambiguous (sub-)resource method for HTTP method POST
and input mime-types as defined by"@Consumes" and "@Produces" annotations at
Java methods public sokkalingam.restapi.messenger.model.Message
sokkalingam.restapi.messenger.resources.MessageResource.addMessage(java.lang.Strin
g,sokkalingam.restapi.messenger.model.Message) and public
sokkalingam.restapi.messenger.model.Comment
sokkalingam.restapi.messenger.resources.CommentResource.postComment(long,sokkaling
am.restapi.messenger.model.Comment) at matching regular expression /. These two
methods produces and consumes exactly the same mime-types and therefore their
invocation as a resource methods will always fail.;
问题:
应该如何设置我的路径,我的子资源?
什么是更好的方式来做子资源内的子资源?子资源内的子资源是否共用 ?
