Based on the answer for problem with x-www-form-urlencoded with Spring @Controller
I have written the below @Controller method
@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST , produces = {"application/json", "application/xml"} , consumes = {"application/x-www-form-urlencoded"} ) public @ResponseBody Representation authenticate(@PathVariable("email") String anEmailAddress, @RequestBody MultiValueMap paramMap) throws Exception { if(paramMap == null && paramMap.get("password") == null) { throw new IllegalArgumentException("Password not provided"); } }
the request to which fails with the below error
{ "timestamp": 1447911866786, "status": 415, "error": "Unsupported Media Type", "exception": "org.springframework.web.HttpMediaTypeNotSupportedException", "message": "Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported", "path": "/users/usermail%40gmail.com/authenticate" }
[PS: Jersey was far more friendly, but couldn't use it now given the practical restrictions here]
回答1:
The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.
Then try the following:
@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE}) public @ResponseBody Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception { if(paramMap == null && paramMap.get("password") == null) { throw new IllegalArgumentException("Password not provided"); } return null; }
Note that removed the annotation @RequestBody

It seems that now you can just mark the method parameter with @RequestParam and it will do the job for you.
@PostMapping( "some/request/path" ) public void someControllerMethod( @RequestParam Map body ) { //work with Map }
回答3:
Add a header to your request to set content type to application/json
curl -H 'Content-Type: application/json' -s -XPOST http://your.domain.com/ -d YOUR_JSON_BODY
this way spring knows how to parse the content.
