I have a Controller
class with a function that saves a record to the Database. I am passing several parameters to the Controller
function however i think i may be writing the @RequestMapping
incorrectly. Under is the code
Controller
@RequestMapping(value="createRoadBlock.htm", method = RequestMethod.POST)
public @ResponseBody Integer createRoadBlock(@RequestParam String purpose, @RequestParam String userName,
@RequestParam int status, @RequestParam double latAdd,
@RequestParam double longAdd, HttpServletRequest request,
HttpServletResponse response) {
int roadBlockId = 0;
try{
roadBlockId = roadBlockManager.saveRoadBlock(purpose, userName, status,latAdd,longAdd);
logger.info("Create Road Block Successful roadBlockId "+ roadBlockId);
return roadBlockId;
}catch(Exception e){
logger.error("Exception Occured In Road Block Controller "+e.getMessage());
return roadBlockId;
}
}
Ajax Request
$.ajax({
type:'POST',
url:'createRoadBlock.htm',
contentType:"application/json",
async:false,
cache:false,
data:{purpose:f_purpose, userName:f_userName,status: f_status,latAdd: f_latAdd, longAdd:f_lngAdd},
dataType:'json'
}).success(function(recordId){
console.log('Road Block created with id ' + recordId);
});

I got this error for a stupid mistake, the variable name in the @PathVariable wasn't matching the one in the @RequestMapping
For example
@RequestMapping(value = "/whatever/{**contentId**}", method = RequestMethod.POST)
public … method(@PathVariable Integer **contentID**){
}
It may help others
This error may happen when mapping variables you defined in REST definition do not match with @PathVariable names.
Example: Suppose you defined in the REST definition
@GetMapping(value = "/{appId}", produces = "application/json", consumes = "application/json")
Then during the definition of the function, it should be
public ResponseEntity<List> getData(@PathVariable String appId)
This error may occur when you use any other variable other than defined in the REST controller definition with @PathVariable. Like, the below code will raise the error as ID is different than appId variable name:
public ResponseEntity<List> getData(@PathVariable String ID)
