Meu objectMapper está buscando o valor do tipoPage<User> do seguinte modo:

userList = objectMapper.readValue(RestAdapter.get(url), new TypeReference<PageImplBean<User>>(){});

oPageImplBean estendePageImpl classe da seguinte maneira:

public class PageImplBean<T> extends PageImpl<T> {
private static final long serialVersionUID = 1L;
private int number;
private int size;
private int totalPages;
private int numberOfElements;
private long totalElements;
private boolean previousPage;
private boolean first;
private boolean nextPage;
private boolean last;
private List<T> content;
private Sort sort;

public PageImplBean() {
    super(new ArrayList<T>());
}

public int getNumber() {
    return number;
}

public void setNumber(int number) {
    this.number = number;
}

public int getSize() {
    return size;
}

public void setSize(int size) {
    this.size = size;
}

public int getTotalPages() {
    return totalPages;
}

public void setTotalPages(int totalPages) {
    this.totalPages = totalPages;
}

public int getNumberOfElements() {
    return numberOfElements;
}

public void setNumberOfElements(int numberOfElements) {
    this.numberOfElements = numberOfElements;
}

public long getTotalElements() {
    return totalElements;
}

public void setTotalElements(long totalElements) {
    this.totalElements = totalElements;
}

public boolean isPreviousPage() {
    return previousPage;
}

public void setPreviousPage(boolean previousPage) {
    this.previousPage = previousPage;
}



public boolean isNextPage() {
    return nextPage;
}

public void setNextPage(boolean nextPage) {
    this.nextPage = nextPage;
}


public boolean isFirst() {
    return first;
}

public void setFirst(boolean first) {
    this.first = first;
}

public boolean isLast() {
    return last;
}

public void setLast(boolean last) {
    this.last = last;
}

public List<T> getContent() {
    return content;
}

public void setContent(List<T> content) {
    this.content = content;
}

public Sort getSort() {
    return sort;
}

public void setSort(Sort sort) {
    this.sort = sort;
}

public PageImpl<T> pageImpl() {
    return new PageImpl<T>(getContent(), new PageRequest(getNumber(),
            getSize(), getSort()), getTotalElements());
}
}

Minha classe de repositório tem a seguinte aparência:

@EnableScan
@EnableScanCount
public abstract interface UserRepository extends PagingAndSortingRepository<User, String>
{
  public abstract Page<User> findByAddressId(String paramString, Pageable paramPageable);

  public abstract Page<User> findAll(Pageable paramPageable);
}    

Minha classe de serviço é a seguinte:

public Page<User> fetchUserList(String addressId,Integer pageNumber, Integer pageSize){
    Page<User> userPageList = null;

        PageRequest pageRequest = new PageRequest(pageNumber - 1, pageSize, Direction.ASC, "addressId");
        userPageList = userRepository.findByAddressId(addressId, pageRequest);

    return userPageList;
}

MinhasPage<User> O objeto do serviço da web consiste em uma instância paginável com o objeto Sort, que consiste no valor [addressId: ASC].

Ao desserializar o objeto para userList com objectMapper, como mostrado acima, estou encontrando o erro mencionado.

com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of org.springframework.data.domain.Sort out of START_ARRAY token

Qualquer ajuda muito apreciada. Obrigado.
