Http Post with request content type form not working in Spring MVC 3 -

code snippet:

@requestmapping(method = requestmethod.post)//,  headers = "content-type=application/x-www-form-urlencoded") public modelandview create(@requestbody useraccountbean account) {     try{         accounts.put(account.assignid(), account);     }catch(runtimeexception ex)     {         return new modelandview("account/registererror");     }     return new modelandview("account/userverification"); } 

after receiving request, got http status code 415: server refused request because request entity in format not supported requested resource requested method ().

if change code this:

code snippet:

@requestmapping(method = requestmethod.post,headers = "content-type=application/x-www-form-urlencoded") public modelandview create(@requestbody useraccountbean account) {     try{         accounts.put(account.assignid(), account);     }catch(runtimeexception ex)     {         return new modelandview("account/registererror");     }     return new modelandview("account/userverification"); } 

i 405 method not allowed. funny thing in allow header of response, lists , post allowed methods.

i have class josn mapping:

@component public class jacksonconversionserviceconfigurer implements beanpostprocessor {

private final conversionservice conversionservice;  @autowired public jacksonconversionserviceconfigurer(conversionservice conversionservice) {     this.conversionservice = conversionservice; }  public object postprocessbeforeinitialization(object bean, string beanname) throws beansexception {     return bean; }  public object postprocessafterinitialization(object bean, string beanname) throws beansexception {     if (bean instanceof annotationmethodhandleradapter) {         annotationmethodhandleradapter adapter = (annotationmethodhandleradapter) bean;         httpmessageconverter<?>[] converters = adapter.getmessageconverters();         (httpmessageconverter<?> converter : converters) {             if (converter instanceof mappingjacksonhttpmessageconverter) {                 mappingjacksonhttpmessageconverter jsonconverter = (mappingjacksonhttpmessageconverter) converter;                 jsonconverter.setobjectmapper(new conversionserviceawareobjectmapper(this.conversionservice));             }                        }     }     return bean; } 

}

copied spring examples. works great json content-type.

a more general question how make spring mvc request handlers work different request content-types. advice appreciated.

unfortunately formhttpmessageconverter (which used @requestbody-annotated parameters when content type application/x-www-form-urlencoded) cannot bind target classes (as @modelattribute can).

therefore need @modelattribute instead of @requestbody. if don't need pass different content types method can replace annotation:

@requestmapping(method = requestmethod.post) public modelandview create(@modelattribute useraccountbean account) { ... } 

otherwise guess can create separate method form processing form data appropriate headers attribute:

@requestmapping(method = requestmethod.post,      headers = "content-type=application/x-www-form-urlencoded")  public modelandview createfromform(@modelattribute useraccountbean account) { ... } 

edit: possible option implement own httpmessageconverter combining formhttpmessageconverter (to convert input message map of parameters) , webdatabinder (to convert map of parameters target object).
