Request does not work when there are headers

In my controller I have a method below which works well

@RequestMapping(value="/searchresults",method = RequestMethod.GET)
public SearchResponse searchResults(
@PathVariable("domain") String domain,
@RequestParam(value="rowCount" , defaultValue="0",  required=false) Integer rowCount,
HttpServletRequest req){}

but the same doesn't work when adding headers,

@RequestMapping(value="/searchresults", method = RequestMethod.GET,headers = "application/json;charset=UTF-8")
public SearchResponse searchResults(
@PathVariable("domain") String domain,
@RequestParam(value="rowCount" , defaultValue="0",  required=false) Integer rowCount,
HttpServletRequest req){}

Exception: View: null org.springframework.web.servlet.mvc.multiaction.NoSuchRequestHandlingMethodException: No matching handler method found for servlet t request: path '/search/searchresults.json', method 'GET',

I tried the following:

@RequestMapping(value="/searchresults", method = RequestMethod.GET,headers = {"content-type=application/json,charset=UTF-8"})

but it throws, java.lang.IllegalArgumentException: "charset = UTF-8" does not contain '/'

How to resolve it

You forgot to add header names: |

application/json

- Content-Type , and UTF-8

- Charset .

Check out the complete list of HTTP headers .



The correct display will be as follows:

@RequestMapping(value="/searchresults", method = RequestMethod.GET, 
                       headers = {"content-type=application/json,charset=UTF-8"})

However, it's worth knowing that the ContentType should only be specified for POST and PUT requests .

You also need to provide a header name which is content-type

. Change this:

headers ="application/json;charset=UTF-8"


to

headers = {"content-type=application/json,charset=UTF-8"}

Change headers

toproduces 

@RequestMapping(value="/searchresults", method = RequestMethod.GET,produces = "application/json;charset=UTF-8")
public SearchResponse searchResults(
@PathVariable("domain") String domain,
@RequestParam(value="rowCount" , defaultValue="0",  required=false) Integer rowCount,
HttpServletRequest req){}

Ideally you should use @RestController

if using Spring 4

Use; instead of <

@RequestMapping(value="/searchresults", method = RequestMethod.GET,headers = {"content-type=application/json;charset=UTF-8"})

A workaround for anyone using WebLogic and possibly other app servers does the same, here's what worked for me in weblogic.xml

<wls:charset-params>
        <wls:input-charset>
              <wls:resource-path>/restful</wls:resource-path>
              <wls:java-charset-name>UTF-8</wls:java-charset-name>
        </wls:input-charset>
</wls:charset-params>

My Request Mapping annotations look like this:

@RequestMapping(method = RequestMethod.POST, value = "/echo", produces = "text/plain;charset=UTF-8", headers = "Accept=*/*")

addition

headers = {"content-type=application/json,charset=UTF-8"}

didn't help and I'm puzzled as to why, but I got away somehow. NTN

I found this helpful (stuck with Spring 3.0.x):

@ResponseBody
public ResponseEntity<String> getResponse() {
  String body = ...
  MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
  headers.set("Content-Type", "application/json;charset=UTF-8");
  return new ResponseEntity<String>(body, headers, HttpStatus.OK);
}
