本文介绍了如何在java restful服务中使用json参数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我如何在我的webservice中使用json参数,我可以使用@PathParam获取参数但是获取json数据作为参数不知道该怎么做。How can i consume json parameter in my webservice, I can able to get the parameters using @PathParam but to get the json data as parameter have no clue what to do.@GET@Path("/GetHrMsg/json_data")@Consumes({ MediaType.APPLICATION_JSON })@Produces(MediaType.APPLICATION_JSON)public String gethrmessage(@PathParam("emp_id") String empid) { }代替@PathParam使用什么以及稍后如何解析它。What to use in place of @PathParam and how to parse it later.推荐答案我假设您正在讨论使用请求发送的JSON邮件正文。I assume that you are talking about consuming a JSON message body sent with the request.如果是这样,请注意虽然没有被禁止,但是GET请求不有请求主体是一个普遍的共识。有关解释原因,请参阅 HTTP GET with request body 问题。If so, please note that while not forbidden outright, there is a general consensus that GET requests should not have request bodies. See the "HTTP GET with request body" question for explanations why.我之所以提到这一点,只是因为您的示例显示了GET请求。如果您正在进行POST或PUT,请继续阅读,但如果您确实在项目中执行GET请求,我建议您改为 kondu的解决方案。I mention this only because your example shows a GET request. If you are doing a POST or PUT, keep on reading, but if you are really doing a GET request in your project, I recommend that you instead follow kondu's solution.话虽如此,要使用JSON或XML消息体,请包含一个(未注释的)方法参数,该参数本身就是表示消息的JAXB bean。With that said, to consume a JSON or XML message body, include an (unannotated) method parameter that is itself a JAXB bean representing the message.所以,如果您的邮件正文如下所示:So, if your message body looks like this:{"hello":"world","foo":"bar","count":123}然后你将创建一个如下所示的相应类:Then you will create a corresponding class that looks like this:@XmlRootElementpublic class RequestBody { @XmlElement String hello; @XmlElement String foo; @XmlElement Integer count;}您的服务方式如下:@POST@Path("/GetHrMsg/json_data")@Consumes(MediaType.APPLICATION_JSON)@Produces(MediaType.APPLICATION_JSON)public void gethrmessage(RequestBody requestBody) { System.out.println(requestBody.hello); System.out.println(requestBody.foo); System.out.println(requestBody.count);}哪一项会输出:worldbar123 有关使用JAXB使用不同类型的HTTP数据的更多信息,我建议您查看问题如何在RESTful POST方法中访问参数,这里有一些很棒的信息。For more information about using the different kinds of HTTP data using JAXB, I'd recommend you check out the question "How to access parameters in a RESTful POST method", which has some fantastic info. 这篇关于如何在java restful服务中使用json参数的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
