We have an application created in spring-boot. We have a rest controller in place as below
#RequestMapping(value = "getDataFromSpaceForTypeForSpaceId/{gridName}/{spaceName}/{dataType}/{spaceId}", method = GET, produces = "application/json")
public DetailedJsonView getDataFromSpaceForTypeForSpaceId(#PathVariable String spaceId,
#PathVariable String dataType,
#PathVariable String gridName,
#PathVariable String spaceName) throws Exception {
Object detailedObject = spaceAccessorService.getDetailedDataFromSpaceForTypeNameWithSpaceId(gridName, spaceName, dataType, spaceId);
String detailedXml = ObjectMarshallarService.marshal(detailedObject);
return new DetailedJsonView(detailedXml);
}
for the urls like this it works fine
http://localhost:8080/rest/query/getDataFromSpaceForTypeForSpaceId/COLO/gcmmprivateSpace/com.ambuj.ValuationSliceRun/InterestRates
for the urls like this the last variable spaceId
http://localhost:8080/rest/query/getDataFromSpaceForTypeForSpaceId/COLO/gcmmprivateSpace/com.ambuj.ValuationSliceRun/InterestRates#MUREX:RATES:EMEA:2015-01-01
Now what we see on the above url is that spaceId comes as InterestRates instead of InterestRates#MUREX:RATES:EMEA:2015-01-01.
I am not sure how i can resolve that

I have two spring controller methods :
#RequestMapping(value="/requestotp",method = RequestMethod.POST,params = "!applicationId") //new customer
public OTPResponseDTO requestOTP( #RequestBody CustomerDTO customerDTO){
return customerService.requestOTP(customerDTO);
}
#RequestMapping(value="/requestotp",method = RequestMethod.POST,params = {"idNumber","applicationId"}) //existing customer
public String requestOTP( #RequestParam(value="idNumber") String idNumber , #RequestParam(value="applicationId") String applicationId) {
return customerService.requestOTP(idNumber, applicationId);
}
using "!applicationId" , I am expecting that when I call the url with applicationId parameter there that the second method will be called , but actually when I pass a request like this :
{"idNumber":"345","applicationId":"64536"}
The first method gets called
This is the part of the params paremeters documentation that I rely on :
Finally, "!myParam" style expressions indicate that the specified
parameter is not supposed to be present in the request.
Can't you just simply delete first request params?
#RequestMapping(value="/requestotp",method = RequestMethod.POST) //new customer
public OTPResponseDTO requestOTP( #RequestBody CustomerDTO customerDTO){
return customerService.requestOTP(customerDTO);
}
The issue actually wasn't with negating the parameter, the issue was that I was sending {"idNumber":"345","applicationId":"64536"} in the POST body and I was expecting the variables to be mapped to the method parameters annotated with #RequestParam ... this is not correct ... #RequestParam only map URL parameters .... so the controller was trying to find the best match so it was using the first method as it contained #RequestBody
I'm having an issue parsing an URL with Spring.
My endpoint is
#RequestMapping(path = "/register", method = RequestMethod.GET)
public String userActivation(#RequestParam("token") String token, #RequestParam("code") String code, final Map<String, Object> model) {
...
}
So I am expecting a token and a code in the URL.
The problem I am facing is that the service redirecting to my page omits the question mark, something like:
http://myapp/register/&token=sdgddfs&code=fdasgas
Which Spring fails to match to my endpoint.
Is there any way to handle this?
You can re-write you method using #PathVariable instead of #RequestParam
So you'll have an URL like http://myapp/register/sdgddfs/fdasgas, and an annotation for method
#RequestMapping(path = "/register/{token}/{code}")
public String userActivation(#PathVariable("token") String token, #PathVariable("code") String code) { ... }
I have following REST controller in Java Spring Application:
#RequestMapping(
value = "/api/getApplication/{me_userId}",
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE)
public Object getApplication(
#PathVariable String userId,
#RequestParam(value="fieldNames[]", required = false) String[] fieldNames) {
if (fieldNames != null) {
for (String fieldName : fieldNames)
System.out.println(fieldName);
}
...
return null;
}
So I can not succeed in simulating API call from DHC REST of POSTMAN what will pass that fieldNames[].
Does anyone know how to do it?
First of all, your current method does not work because your #PathVariable is wrong. In your #RequestMapping you have the following placeholder in your path: {me_userId}, which means that it will be mapped to a path variable with that name.
However, the only #PathVariable you have is nameless, which means it will use the name of the parameter (userId) in stead.
So before you try to execute your request, you have to change your #RequestMapping into:
#RequestMapping(
value = "/api/getApplication/{userId}", // <-- it's now {userId}
method = RequestMethod.GET,
produces = MediaType.APPLICATION_JSON_VALUE)
Then, if you run the application, you can kinda choose how you want to pass your parameters. Both the following will work:
?fieldNames[]=test,test2
Or:
?fieldNames[]=test&fieldNames[]=test2
Both these results should print the desired results.
Suppose a hyperlink is clicked and an url is fired with the following parameter list myparam=myValue1&myparam=myValue2&myparam=myValue3 . Now how can I capture all the parameters using #RequestParam in spring mvc?
My requirement is I have to capture all the params and put them in a map.
Please help!
#RequestMapping(value = "users/newuser", method = RequestMethod.POST)
public String saveUser(#RequestParam Map<String,String> requestParams) throws Exception{
String userName=requestParams.get("email");
String password=requestParams.get("password");
//perform DB operations
return "profile";
}
You could use RequestParam in the above mentioned manner.
It seems you can't get
Map<String,String>
because all your params have same name "myparam"
Try this instead:
public ModelAndView method(#RequestParam("myparam") List<String> params) { }
To get all parameters at once try this:
public ModelAndView postResultPage(#RequestParam MultiValueMap<String, String> params)
This feature is described in the #RequestParam java doc (3. Paragraph):
Annotation which indicates that a method parameter should be bound to a web request parameter. Supported for annotated handler methods in Servlet and Portlet environments.
If the method parameter type is Map and a request parameter name is specified, then the request parameter value is converted to a Map assuming an appropriate conversion strategy is available.
If the method parameter is Map<String, String> or MultiValueMap<String, String> and a parameter name is not specified, then the map parameter is populated with all request parameter names and values.
As of Spring 3.0, you can also use MultiValueMap to achieve this:
A rudimentary example would be:
public String someMethod(#RequestParam MultiValueMap<String,String> params) {
final Iterator<Entry<String, List<String>>> it = params.entrySet().iterator();
while(it.hasNext()) {
final String k = it.next().getKey();
final List<String> values = it.next().getValue();
}
return "dummy_response";
}
If anyone is trying to do the same in Spring Boot, use RequestBody in place of RequestParam
Spring mvc can support List<Object>, Set<Object> and Map<Object> param, but without #RequestParam.
Take List<Object> as example, if your object is User.java, and it like this:
public class User {
private String name;
private int age;
// getter and setter
}
And you want pass a param of List<User>, you can use url like this
http://127.0.0.1:8080/list?users[0].name=Alice&users[0].age=26&users[1].name=Bob&users[1].age=16
Remember to encode the url, the url after encoded is like this:
http://127.0.0.1:8080/list?users%5B0%5D.name=Alice&users%5B0%5D.age=26&users%5B1%5D.name=Bob&users%5B1%5D.age=16
Example of List<Object>, Set<Object> and Map<Object> is displayed in my github.
You can use for multiple Params as such
public String saveUser(#RequestParam("email") String userName, #RequestParam("password") String password) throws Exception{
//your code
//perform DB operations
return "profile";
}
For params with same name, you can use MultiValueMap<String ,String>. Then all the values would be present as List
You can use multiple #RequestParam annotations as shown below.
#RequestParam(value="myparam1", required = true) <Datatype> myparam1,
#RequestParam(value = "myparam2", required = false) <Datatype> myparam2,
I need to take two parameters in my spring controller.
http://mydomain.com/myapp/getDetails?Id=13&subId=431
I have controller which will return Json for this request.
#RequestMapping(value = "/getDetails", method = RequestMethod.GET,params = "id,subId", produces="application/json")
#ResponseBody
public MyBean getsubIds(#RequestParam String id, #RequestParam String subId) {
return MyBean
}
I am getting 400 for when i tried to invoke the URL. Any thoughts on this?
I was able to get it with one parameter.
Try specifying which parameter in the query string should match the parameter in the method like so:
public MyBean getsubIds(#RequestParam("id") String id, #RequestParam("subId") String subId) {
If the code is being compiled without the parameter names, Spring can have trouble figuring out which is which.
As for me it works (by calling: http://www.example.com/getDetails?id=10&subId=15):
#RequestMapping(value = "/getDetails", method = RequestMethod.GET, produces="application/json")
#ResponseBody
public MyBean getsubIds(#RequestParam("id") String id, #RequestParam("subId") String subId) {
return new MyBean();
}
P.S. Assuming you have class MyBean.
