我想提供一个仅提供true/false布尔值响应的boolean REST服务.
I want to provide a boolean REST service that only provides true/false boolean response.
但是以下方法不起作用.为什么?
But the following does not work. Why?
@RestController @RequestMapping("/") public class RestService { @RequestMapping(value = "/", method = RequestMethod.GET, produces = MediaType.APPLICATION_XML_VALUE) @ResponseBody public Boolean isValid() { return true; } }结果:HTTP 406: The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers.
推荐答案您不必删除@ResponseBody,您只需删除MediaType:
You don't have to remove @ResponseBody, you could have just removed the MediaType:
@RequestMapping(value = "/", method = RequestMethod.GET) @ResponseBody public Boolean isValid() { return true; }在这种情况下,它将默认为application/json,因此也可以使用:
in which case it would have defaulted to application/json, so this would work too:
@RequestMapping(value = "/", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE) @ResponseBody public Boolean isValid() { return true; }如果指定MediaType.APPLICATION_XML_VALUE,则您的响应实际上必须可序列化为XML,而true则不能.
if you specify MediaType.APPLICATION_XML_VALUE, your response really has to be serializable to XML, which true cannot be.
此外,如果您只想在响应中输入普通的true,那不是真的XML吗?
Also, if you just want a plain true in the response it isn't really XML is it?
如果您特别想要text/plain,则可以这样做:
If you specifically want text/plain, you could do it like this:
@RequestMapping(value = "/", method = RequestMethod.GET, produces = MediaType.TEXT_PLAIN_VALUE) @ResponseBody public String isValid() { return Boolean.TRUE.toString(); }更多推荐
如何返回带有休息的布尔值?
