Estoy creando una aplicación en java utilizando restlet y de Hibernación .

He usuario de clase de entidad, y siempre que tengo llamar a get de http .
Estoy recibiendo el error .

{
    "error": "20000:Hibernate Exception. : org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of tecd.persistence.entity.User.idUser",
    "status": 500
}

Aquí Está mi clase de entidad .

Por favor, me sugieren cuál es el problema aquí .¿Hay alguna versión de java problema o lo que no soy capaz de averiguar esta cuestión .

De las tablas de Mysql parece

CREATE TABLE `user` (
`idUser` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,

    Su idUser se define como un valor de tipo long en db. En su Objeto es un String. Por favor, cambie a Integer.

    • debido a alguna razón no quiero cambiar iduser tipo de string a int por lo tanto puedo cambiar el tipo varchar en db y mismo en hbm archivo, pero todavía no está funcionando
    • Se puede cambiar el methodname getidUser y setidUser a getIdUser y setIdUser y probar de nuevo?
  2. 1

    En Java @Entidad Usuario, el idUser campo tiene la anotación @GeneratedValue(strategy = GenerationType.AUTO). Esto significa que Hibernate generar un valor ENTERO único en la base de datos, es decir, se le asignará un NÚMERO que nunca se ha utilizado en la base de datos, y nunca será reciclado.

    Porque ha establecido idUser para el tipo de Cadena, usted está recibiendo el IllegalArgumentException.

    Considere el siguiente código:

    @GeneratedValue(strategy = GenerationType.AUTO)
    public void setIdUser(int idUser){
    this.idUser = "" + idUser;
    }
    public String getIdUser(){
    return this.idUser;
    }

    Esto le dice a hibernate para inyectar el código único de identificación mediante el setter siempre, y el setter asignará el número entero como una Cadena.

    Espero que esto ayude!

    EDITAR

    Además, tendrás a cambiar su esquema de base de datos para aceptar el tipo VARCHAR de campo idUser.
