When I use Springmvc's @requestbody and @responsebody annotations to process JSON data, there is always a 415 error, saying that the submitted data format is not supported, I used jquery Ajax in the page to emit JSON data to the server:
$.ajax ({ type:' post ', URL:' ${pagecontext.request.contextpath}/ Requestjson.action ', contentType:' application/json;charset=utf-8 ', // The data is JSON: ' {' name ': ' Phone ', ' Price ': 9999} ', success:function(data) { alert (data); } });The contenttype type is also specified, but there are 415
Finally I found out that the jar used was a problem, and the jar I used originally was:
The spring version is 4.3.6, which always appears 415, and finally I replace the jar package with:
Yes, it's a problem between versions.
