@springbootapplication @componentscan(basepackages="webapi") public class application {       public static void main(string[] args) throws exception{         springapplication.run(application.class, args);      }  } 

greeting.java

public class greeting {      private biginteger id;     private string text;      public greeting() {      }      public biginteger getid() {         return id;     }      public void setid(biginteger id) {         this.id = id;     }      public string gettext() {         return text;     }      public void settext(string text) {         this.text = text;     }  } 

greetingcontroller.java

@restcontroller  public class greetingcontroller {        private static biginteger nextid;     private static map<biginteger, greeting> greetingmap;       private static greeting save(greeting greeting) {         if (greetingmap == null) {             greetingmap = new hashmap<biginteger, greeting>();             nextid = biginteger.one;          }         greeting.setid(nextid);         nextid = nextid.add(biginteger.one);         greetingmap.put(greeting.getid(), greeting);         return greeting;     }      static {         greeting g1 = new greeting();         g1.settext("hello world");         save(g1);          greeting g2 = new greeting();         g2.settext("hola mundo!");         save(g2);      }        @requestmapping(value = "/api/greetings", method = requestmethod.get, produces = mediatype.application_json_value)      public responseentity<collection<greeting>> getgreetings() {         collection<greeting> greetings = greetingmap.values();          return new responseentity<collection<greeting>>(greetings,                 httpstatus.ok);     }       @requestmapping(value = "/api/greetings/{id}", method = requestmethod.get, produces = mediatype.application_json_value)      public responseentity<greeting> getgreeting(             @pathvariable("id") biginteger id)     {         greeting greeting = greetingmap.get(id);         if (greeting == null) {             return new responseentity<greeting>(httpstatus.not_found);         }         return new responseentity<greeting>(greeting, httpstatus.ok);      }       @requestmapping(value = "/api/greetings", method = requestmethod.post, consumes = mediatype.application_json_value, produces = mediatype.application_json_value)     @responsebody     public responseentity<greeting> creategreeting(             @requestbody greeting greeting) {         greeting savedgreeting = save(greeting);         return new responseentity<greeting>(savedgreeting, httpstatus.created);     }  } 

the service expecting application/json content-type receiving text/plain input.

what using make the post? if testing postman sure add content-type application/json value in headers section.
