创建服务POST spring框架

Question

我在春季阶段有一个服务，在那里我得到一个类似@ResquestBody的对象来执行注册，但是POST方法不起作用，在JSON步骤时返回错误。下面是错误和代码：

错误： Image (Unexpected '<')

代码：

@RequestMapping(value = "/cliente/", method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<?> createUser(@RequestBody Cliente user) {
    logger.info("Creating User : {}", user);

    if (clienteService.isUserExist(user)) {
        logger.error("Unable to create. A User with name {} already exist", user.getNome());
        return new ResponseEntity(new CustomErrorType("Unable to create. A User with name " +
        user.getNome() + " already exist."),HttpStatus.CONFLICT);
    }
    clienteService.save(user);
    return new ResponseEntity<String>(HttpStatus.CREATED);
}

班级：

   @Entity
@JsonIgnoreProperties({ "hibernateLazyInitializer", "handler" })
public class Cliente implements Serializable{

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue
    private Long id;
    private String nome;
    private String telefone;
    private String endereco;
    private String cidade;
    private String estado;
    private String cnpjCpf;
    private String email;
    private String senha;

    @Lob
    @Column(name = "imagem")
    private byte[] imagem;

    public Cliente(Long id, String nome, String telefone, String endereco, String cidade, String estado,
            String cnpjCpf, String email, String senha, byte[] imagem) {
        this.id = id;
        this.nome = nome;
        this.telefone = telefone;
        this.endereco = endereco;
        this.cidade = cidade;
        this.estado = estado;
        this.cnpjCpf = cnpjCpf;
        this.email = email;
        this.senha = senha;
        this.imagem = imagem;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public String getTelefone() {
        return telefone;
    }

    public void setTelefone(String telefone) {
        this.telefone = telefone;
    }

    public String getEndereco() {
        return endereco;
    }

    public void setEndereco(String endereco) {
        this.endereco = endereco;
    }

    public String getCidade() {
        return cidade;
    }

    public void setCidade(String cidade) {
        this.cidade = cidade;
    }

    public String getEstado() {
        return estado;
    }

    public void setEstado(String estado) {
        this.estado = estado;
    }

    public String getCnpjCpf() {
        return cnpjCpf;
    }

    public void setCnpjCpf(String cnpjCpf) {
        this.cnpjCpf = cnpjCpf;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getSenha() {
        return senha;
    }

    public void setSenha(String senha) {
        this.senha = senha;
    }

    public byte[] getImagem() {
        return imagem;
    }

    public void setImagem(byte[] imagem) {
        this.imagem = imagem;
    }

    public static long getSerialversionuid() {
        return serialVersionUID;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + (int) (id ^ (id >>> 32));
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Cliente other = (Cliente) obj;
        if (id != other.id)
            return false;
        return true;
    }
}

图中显示，在使用邮递员应用程序执行POST时，我们会收到错误消息。
