How can the callbackFacebook function get the value of code from the uri?
uri = http://localhost:8081/callback?code=AQDNm6hezKdTsId5k4oXKNo
#RequestMapping(value = "/callback?{code}", method = RequestMethod.GET)
public String callbackFacebook(Model model, #PathVariable(name = "code") String code) {
System.out.println(code);
return "login";
}
Try this. code is a query parameter judging by your URL, not a path variable. Path variables are a part of the path itself (i.e. if your URL was something like /{code}/callback, then code is a PathVariable).
#RequestMapping(value = "/callback", method = RequestMethod.GET)
public String callbackFacebook(Model model, #RequestParam(value = "code") String code) {
System.out.println(code);
return "login";
}
If your URL is http://localhost:8081/callback?code=AQDNm6hezKdTsId5k4oXKNo then it is case of request parameters so the method will be like below.
#RequestMapping(value = "/callback", method = RequestMethod.GET)
public String callbackFacebook(Model model, #RequestParam(value = "code") String code) {
return "login";
}
If your URL is http://localhost:8081/callback/AQDNm6hezKdTsId5k4oXKNo then then it is case of path variables method will be like below.
#RequestMapping(value = "/callback/{code}", method = RequestMethod.GET)
public String callbackFacebook(Model model, #PathVariable(value = "code") String code) {
return "login";
}
Refer requestparam-vs-pathvariable for better clarity.
I will explain 2 ways.
1-If it is added in the session in somewhere in the project as attribute,You can get it like this :
#RequestMapping(value = "/callback?{code}", method = RequestMethod.GET)
public String callbackFacebook(Model model, #PathVariable(name = "code") String code,HttpServletRequest request) {
String code1 = request.getSession().getAttribute("code").toString();
return "login";
}
example output : AQDNm6hezKdTsId5k4oXKNo
2-You can directly get URL.But then you need to parse URL.Because all URL is coming.
#RequestMapping(value = "/callback?{code}", method = RequestMethod.GET)
public String callbackFacebook(Model model, #PathVariable(name = "code") String code,HttpServletRequest request) {
StringBuffer requestURL = request.getRequestURL();
return "login";
}
example output : http://localhost:8081/callback?code=AQDNm6hezKdTsId5k4oXKNo

I have a Spring controller mapping like following:
#RequestMapping(value = "api/{pathVar1}/receipt", method = RequestMethod.POST)
#ResponseBody
public String generateReceipt(HttpServletRequest request, #PathVariable String pathVar1) {
....
}
In this case what if the pathVar1 has slash('/').
Example request:
'api/CODE/1/receipt'
pathVar1 is supplied with
'CODE/1'
.
I guess it's not the cleanest solution, but it seems to be working:
Replace #PathVariable in API path with ** to accept anything between "api/" and "/receipt", and then extract the needed part of path.
#RequestMapping(value = "api/**/receipt", method = RequestMethod.POST)
#ResponseBody
public String generateReceipt(HttpServletRequest request) {
String path = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
String bestMatchPattern = (String) request.getAttribute(HandlerMapping.BEST_MATCHING_PATTERN_ATTRIBUTE);
String apiPath = new AntPathMatcher().extractPathWithinPattern(bestMatchPattern, path);
String neededPathVariableValue = apiPath.substring(0, apiPath.length() - "/receipt".length());
//...
}
I have the following String that I receive in my rest service:
.6.75:5050/pretups/C2SReceiver?REQUEST_GATEWAY_CODE=8050122997&REQUEST_GATEWAY_TYPE=EXTGW&LOGIN=CO8050122997_EXTGW&PASSWORD=89b87741ca3f73b0b282ae165bad7501&SOURCE_TYPE=XML&SERVICE_PORT=190
I have the following code:
#Controller
public class servicioscontroller {
#RequestMapping(value = "/pretups/{p1}?{trama}", method = RequestMethod.GET)
#ResponseBody
public String enviarTrama(#PathVariable("p1") String p1,#PathVariable("trama") String trama){
return p1+trama;
}
}
And im getting this result:
C2SReceive
I need also the string after that ?, what im doing wrong or how do I get that? thanks
You should use #RequestParam:
#Controller
public class servicioscontroller {
#RequestMapping(value = "/pretups/{p1}", method = RequestMethod.GET, params = ["trama"])
#ResponseBody
public String enviarTrama(
#PathVariable("p1") String p1,
#RequestParam(name = "trama", required = "true") String trama
){
return p1+trama;
}
}
Note that you have to put request params in the #RequestMapping's params attribute instead of the path string.
The difference between #RequestParam and #PathParam is described in this answer.
My RequestMapping & ResponseBody is like this:
#RequestMapping(value = "/someURL", method = RequestMethod.GET, produces = "application/json")
#ResponseBody
public ModelAndView getDetails(
#RequestParam(value = "param1", required = false) String param1,
#RequestParam(value = "param2", required = false) String param2,
{
Now on the basis of param1, I want to redirect to a particular URL.
Eg. Right now after processing, my page is going to
http://parent-domain/someURL?param1=...param2=...
But what I want is to completely change the parent domain like this
http://some-other-domain/someURL?param1=...param2=...
Do something like this:
#RequestMapping(value = "/someURL", method = RequestMethod.GET, produces = "application/json")
public ModelAndView getDetails(#RequestParam(value = "param1", required = false) String param1,
#RequestParam(value = "param2", required = false) String param2) {
if (param1.equals("a"))
return new ModelAndView("redirect:somotherurl");
else
return new ModelAndView("redirect:http://google.com");
}
if param1 is a then it will go to someotherurl in parent else it will redirect to google.com
I have problem with mapping in spring 3 mvc. General I must "send" value (#RequestMapping(value = "/*") to my return statement. How it resolve? I was thinking about this:
#RequestMapping(value = "/*", method = RequestMethod.GET)
public String homeForm( Model model, HttpServletResponse response) throws IOException {
logger.info("Welcome ");
String url=response.getWriter().toString();
return url;
}
Is it good solutions, maybe someone has any advices?
Thaks
If you want to return the string that comes after the slash, you could do something like this:
#RequestMapping(value = "/{foo}", method = RequestMethod.GET)
public #ResponseBody String homeForm(#PathVariable("foo") String foo) {
return foo;
}
#RequestMapping(value = "/article", method = RequestMethod.GET)
public final String article(final ModelMap model)
{
}
If this is called using the address:
/article/1234abcd
How can the value 1234abcd be retrieved from inside the article method?
By using #PathVariable:
#RequestMapping(value = "/article/{articleId}", method = RequestMethod.GET)
public final String article(final ModelMap model, #PathVariable String articleId)
{
}
See Spring docs for more info.
