Post Spring Data in Restful Controllers with Angular.JS, getting bad request - angularjs

Question

I'm trying to post a simple model using Restful controllers in Spring Boot, but when I'd like my relationship objects it won't work.
I'm using the latest version of Spring
The Controller Method:
#RequestMapping(value= "rest/person/create", method = RequestMethod.POST)
public ResponseEntity<Person> createOrUpdate(#RequestBody Person person){
System.out.println("creating!");
try{
if (person != null){
peopleRepository.save(person);
}
}
catch (Exception e){
e.printStackTrace();
return new ResponseEntity<Person>(HttpStatus.UNAUTHORIZED);
}
return new ResponseEntity<Person>(HttpStatus.OK);
}
The Person class:
#Entity
public class Person {
#Id
#GeneratedValue
private Long id;
#Temporal(TemporalType.DATE)
#DateTimeFormat(pattern = "dd/MM/yyyy")
private Date registryDate;
#Temporal(TemporalType.DATE)
#DateTimeFormat(pattern = "dd/MM/yyyy")
private Date updateDate;
private String firstName;
private String lastName;
#Temporal(TemporalType.DATE)
#DateTimeFormat(pattern = "dd/MM/yyyy")
private Date birthDate;
private String gender;
private String rg;
private String cpf;
private String phone;
private String celPhone;
#ManyToOne
private Address address;
#Column(unique=true)
private String email;
private String observation;
byte situation;
protected Person(){}
public Person(Long id, Date registryDate, Date updateDate,
String firstName, String lastName, Date birthDate, String gender, String rg,
String cpf, String phone, Address address, String email,
String observation, byte situation) {
super();
this.id = id;
this.registryDate = registryDate;
this.updateDate = updateDate;
this.firstName = firstName;
this.lastName = lastName;
this.birthDate = birthDate;
this.gender = gender;
this.rg = rg;
this.cpf = cpf;
this.phone = phone;
if (address != null)
this.address = address;
this.email = email;
this.observation = observation;
this.situation = situation;
}
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;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Date getRegistryDate() {
return registryDate;
}
public void setRegistryDate(Date registryDate) {
this.registryDate = registryDate;
}
public Date getUpdateDate() {
return updateDate;
}
public void setUpdateDate(Date updateDate) {
this.updateDate = updateDate;
}
public Date getBirthDate() {
return birthDate;
}
public void setBirthDate(Date birthDate) {
this.birthDate = birthDate;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getRg() {
return rg;
}
public void setRg(String rg) {
this.rg = rg;
}
public String getCpf() {
return cpf;
}
public void setCpf(String cpf) {
this.cpf = cpf;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getObservation() {
return observation;
}
public void setObservation(String observation) {
this.observation = observation;
}
public byte getSituation() {
return situation;
}
public void setSituation(byte situation) {
this.situation = situation;
}
public String getCelPhone() {
return celPhone;
}
public void setCelPhone(String celPhone) {
this.celPhone = celPhone;
}
}
The JSON Object:
var person = {"firstName":"Joao","lastName":"Silva",
"gender":"Masculino","rg":"808080",
"cpf":"00","phone":"0","celPhone":"0",
"address":{"street":"Rua","number":5,"neighborhood":"Bairro",
"city":{"name":"Cidade",
"state":{"name":"Rio Grande do Sul","uf":"RS"},
"uf":"AE"},"cep":"Cep","complement":"Complemento"},
"email":"maluco#gmail.com","observation":"poisé","situation":0};
And the Angular.JS post ->
$http.post('rest/person/create', person).
success(function(data, status, headers, config) {
console.log('all good!');
$scope.create = true;
}).
error(function(data, status, headers, config) {
console.log('error');
$scope.create = false;
});
I've been looking how to do it, and could'nt find it.
I'm completely beginner with Spring
The error happens only with the relationships, if I remove
"address":{"street":"Rua","number":5,"neighborhood":"Bairro",
"city":{"name":"Cidade",
"state":{"name":"Rio Grande do Sul","uf":"RS"},
"uf":"AE"},"cep":"Cep","complement":"Complemento"}
It will work.

You need to declare Content-Type when you post a request, and then #RequesetBody annotation convert http body text to a JSON object using jackson.
So you need to change your content-types, and stringify your json object.
$http({
url: 'rest/person/create',
dataType: 'json',
method: 'POST',
data: JSON.stringify(persion),
headers: {
"Content-Type": "application/json"
}
}).success(function(response){
$scope.response = response;
}).error(function(error){
$scope.error = error;
});
