rest - 400 Bad Request when posting JSON Array to a Spring controller -

i have been successful in sending simple json object on spring framework controller

curl -v -h  "content-type: application/json" -h "accept: application/json"  -d '{"lastname":"smith","firstname":"john"}' http://localhost:8080/webservices02/aura/testjsonarray 

however, when send on json object embedded array

curl -v -h  "content-type: application/json" -h "accept: application/json"  -d '{"lastname":"smith","pals":[{"name":"billy"}],"firstname":"john"}' http://localhost:8080/webservices02/aura/testjsonarray 

i error 400 'the request sent client syntactically incorrect ().'

my controller

@controller @requestmapping(value="/aura") public class auracontroller {  @requestmapping(value = "/testjsonarray", method = requestmethod.post,  headers = {"content-type=application/json"}) @responsebody public void testjsonarray(@requestbody  aura aura){     system.err.println("called testjsonarray(): " + "aura " + aura.tostring()); } 

}

my aura class defined

import java.io.serializable; import java.util.list; import org.json.jsonobject;  public class aura implements serializable {  public class pal{     private string name;      public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }  }   private string firstname;  private string lastname;  public string getfirstname() {     return firstname; }  public void setfirstname(string firstname) {     this.firstname = firstname; }  public string getlastname() {     return lastname; }  public void setlastname(string lastname) {     this.lastname = lastname; }  private list<pal> pals;  public string tostring(){     return new jsonobject(this).tostring();  }  public list<pal> getpals() {     return pals; }  public void setpals(list<pal> pals) {     this.pals = pals; } 

}

my bean (under mvc:message-converters) is

<bean class="org.springframework.http.converter.json.mappingjacksonhttpmessageconverter"/>

you have include jackson json mapper dependency jackson-core-asl , jackson-mapper-asl in project.

this necessary mapping json java pojo class fields.
