POmapping json to a pojo using MappingJacksonHttpMessageConverter and POST
text
Body
copied!<p>I am trying to make something very similar to this post using Spring MVC 3.1:</p> <p><a href="https://stackoverflow.com/questions/5908466/jquery-spring-mvc-requestbody-and-json-making-it-work-together">JQuery, Spring MVC @RequestBody and JSON - making it work together</a></p> <p>and trying to get the response as a custom class such as "FooBar" in the example.</p> <p>my ajax call looks like this:</p> <pre><code>// var rule = "giveThisATry"; var rule = { id : 1, name : { name1 : "1", name2 : "2", name3 : "3", name4 : "4" } }; $.ajax({ url : "http://localhost:8080/spring2/save", type : "POST", dataType : "json", //contentType : "application/json; charset=utf-8", data : rule, success : function(data) { alert("success saveRule: " + data); }, error : function(request, status, error) { alert("error saveRule: " + request.responseText); } }); </code></pre> <p>and my rest method looks like this:</p> <pre><code>@RequestMapping(method = RequestMethod.POST, value = "/save") public @ResponseBody MyClass save(@RequestBody MyClass instance, final HttpServletResponse response) { response.setHeader("Access-Control-Allow-Origin", "*"); return MyDB.Save(instance); } </code></pre> <p>Now no matter what I do, Spring would not map the ajax call to this method. Also if i uncomment the line in my ajax call :</p> <pre><code>contentType : "application/json; charset=utf-8", </code></pre> <p>Chrome would change the "request-method" to "OPTIONS" :</p> <pre><code>Request Method:OPTIONS Status Code:200 OK Request Headersview source Accept:*/* Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:en-US,en;q=0.8 Access-Control-Request-Headers:Origin, Content-Type, Accept Access-Control-Request-Method:POST Cache-Control:no-cache Connection:keep-alive Host:localhost:8080 Origin:http://127.0.0.1:8020 Pragma:no-cache Referer:http://127.0.0.1:8020/JQueryPOC/src/index.html User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11 Response Headersview source Allow:GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS Content-Length:0 Date:Fri, 15 Jun 2012 15:07:19 GMT Server:Apache-Coyote/1.1 </code></pre> <p>Now how can i test/debug/have control over the MappingJacksonHttpMessageConverter so that i can map the json to a pojo using requestbody or something else ?</p>
