Dynamic query using JpaRepository
<p>I'm trying to get a  result of a query using JpaRepository, but it doesn't work for me :</p>

<pre><code>public interface PeticionRepository extends JpaRepository&lt;Peticion, Long&gt; {

    @Query(value = "select peticion from Peticion peticion where (peticion.codigo like CONCAT(?1, '%') or "
        + "peticion.contacto.direccionGeneral.nombre like CONCAT(?1, '%') or peticion.contacto.poa like CONCAT(?1, '%') or "
        + "peticion.proyecto.nombre like CONCAT (?1, '%') or peticion.datosAdicionales.estado.nombre like CONCAT(?1, '%'))")
    List&lt;Peticion&gt; findByText(String texto);

    List&lt;Peticion&gt; findByFilter(String unidad, String nombreIniciativa, String codigo,
        LocalDate fechaConsejeroDFormat, LocalDate fechaConsejeroHFormat);
}
</code></pre>

<p>And in other class I need to overwrite the function <code>findByFilter</code> where I'm going to create my query:</p>

<pre><code>public abstract class JpaPeticionRepository implements PeticionRepository {

    @PersistenceContext(name = "ExterroPU") 
    private EntityManager em; 

    public void setEm(EntityManager em) { 
        this.em = em; 
    } 

    public List&lt;Peticion&gt; findByFilter(String unidad, String nombreIniciativa, String codigo,
        LocalDate fechaConsejeroDFormat, LocalDate fechaConsejeroHFormat) {
        List&lt;Peticion&gt; peticiones = new ArrayList&lt;Peticion&gt;();
        String consulta = "select peticion from Peticion peticion ";
        if(unidad!=null || nombreIniciativa!=null || codigo!=null || fechaConsejeroDFormat!=null || fechaConsejeroHFormat!=null){
            consulta=consulta+" where ";
        }
        if(unidad!=null){
            consulta = consulta+" and peticion.contacto.poa ="+unidad;
        }
        if(nombreIniciativa!=null){
            consulta = consulta+" and peticion.proyecto.nombre ="+nombreIniciativa;
        }
        if(codigo!=null){
            consulta = consulta+" and peticion.codigo ="+codigo;
        }
        if(fechaConsejeroDFormat!=null){
            consulta = consulta+" and peticion.datosAdicionales.firmaConsejero&lt;="+fechaConsejeroDFormat;
        }
        if(fechaConsejeroHFormat!=null){
            consulta = consulta+" and peticion.datosAdicionales.firmaConsejero&gt;="+fechaConsejeroHFormat;
        }

        peticiones = (List&lt;Peticion&gt;) em.createQuery(consulta).getResultList();
        return peticiones;
    }
}
</code></pre>
