【问题描述】:
我是一个正在学习构建 RESTful Web 服务的初学者。我想知道如何在 JAX-RS 的子资源中设置子资源的路径。
我有三个资源:个人资料、消息和评论。 我希望我的网址如下所示。
个人资料
/profiles
留言
/profiles/{profileName}/messages
评论
/profiles/{profileName}/messages/{messageId}/comments
我的资源路径如下。
个人资料资源
@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);
}
}
但我收到以下错误,
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:
我应该如何设置子资源的路径?
在子资源中做子资源的更好方法是什么?是吗 子资源内做子资源通用吗?
