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.
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
My REST API method is:
#RequestMapping(value = "/api/test/summary", method = RequestMethod.POST)
postSummaryData(#RequestBody String one, #RequestBody String two) { ... }
#RequestMapping(value = "/api/test/summary/{one}/{two}", method = RequestMethod.POST) postSummaryData( #RequestParam String one, #RequestParam String two) {
}
Also you can try below:
#RequestMapping(value = "/api/test/summary", method = RequestMethod.POST) postSummaryData() {
RequestAttributes attr = RequestContextHolder.getRequestAttributes();
HttpServletRequest request = ((ServletRequestAttributes)attr).getRequest();
// you can get param from this request
}
I try doing confirmation registration from email, on the email I send this code:
String token = UUID.randomUUID().toString(); //for send email
String confirmationUrl = "<a href='" +
"http://localhost:8080/registrationConfirm.html?token="
+ token+"'>Click for end Registration</a>";
helper.setText("message", confirmationUrl.toString());
I receive something like this:
http://localhost:8080/registrationConfirm.html?token=88ab5907-6ab5-40e2-89d5-d6a7e8cea3c2
How I can receive this 88ab5907-6ab5-40e2-89d5-d6a7e8cea3c2 in spring?
I want doing a new controller, he will be check if 88ab5907-6ab5-40e2-89d5-d6a7e8cea3c2 exist in DB, then he activated registration, if no - talk about misstake.
And I do not understand how the conroller will be look, I do so
#RequestMapping(value = "/token", method = RequestMethod.POST)
public #ResponseBody
String getAttr(#PathVariable(value="token") String id,
) {
System.out.println(id);
return id;
}
To complete the comment and hint Ali Dehghani has given (have a look at the answer https://stackoverflow.com/a/17935468/265043):
#RequestMapping(value = "/registrationConfirm", method = RequestMethod.POST)
public #ResponseBody
String getAttr(#RequestParam(value="token") String id) {
System.out.println(id);
return id;
}
Note that I ignored the html suffix in the request mapping annotation. You should read the docs about (default) content negotiation starting at http://docs.spring.io/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-ann-requestmapping-suffix-pattern-match
this another variant
#RequestMapping(value = "/registrationConfirm", method = RequestMethod.POST)
public void getMeThoseParams(HttpServletRequest request){
String goToURL = request.getParameter("token");
System.out.println(goToURL);
}
#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)
{
}
