Enum - PostgresSQL - Java Spring Boot - Hibernate - Error

Question

I am using Hibernate 5.3.11

I'm trying to link an Enum between my PostgresSQL database and my code.

I referred to these links to make my code :

Hibernate mapping between PostgreSQL enum and Java enum
Java Enums, JPA and Postgres enums - How do I make them work together?
Mapping a Java Enum to a database-specific Enumerated column type

Problem
But I still have that error :

org.postgresql.util.PSQLException: ERROR: the column "weather" is of type weatherenum but the expression is of type integer. Hint: You will need to rewrite or cast the expression.

How solve this problem ?

My code

First, I pass through this method, a meteoDTO that I map into a meteo entity :

public MeteoDTO saveMeteo(MeteoDTO meteoDTO) {

        Meteo meteo = MeteoMapper.INSTANCE.meteoFromMeteoDTO(meteoDTO);

        this.meteoRepository.save(meteo); // here, there's a error

        return MeteoMapper.INSTANCE.meteoDTOFromMeteo(meteo);
    }

meteoDTO :

Entity meteo :

Meteo entity

//package and imports

@Entity
@TypeDef(
        name = "pgsql_enum",
        typeClass = PostgreSQLEnumType.class
)
public class Meteo {
    private Integer id;

    @Enumerated(EnumType.STRING)
    @Column(columnDefinition = "weatherenum")
    @Type( type = "pgsql_enum" )
    private WeatherEnum weather;
    ...

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Integer getId() { return id; }

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

    @Basic
    @Column(name = "weather")
    public WeatherEnum getWeather() { return weather; }

    public void setWeather(WeatherEnum weather) {
        this.weather = weather;
    }

   .
   .
   .

}

PostgreSQLEnumType

public class PostgreSQLEnumType extends org.hibernate.type.EnumType {

    public void nullSafeSet(
            PreparedStatement st,
            Object value,
            int index,
            SharedSessionContractImplementor session)
            throws HibernateException, SQLException {
        if(value == null) {
            st.setNull( index, Types.OTHER );
        }
        else {
            st.setObject(
                    index,
                    value.toString(),
                    Types.OTHER
            );
        }
    }
}

I tried also this code :

public class PostgreSQLEnumType extends org.hibernate.type.EnumType {

    public void nullSafeSet(
            PreparedStatement st,
            Object value,
            int index,
            SharedSessionContractImplementor session)
            throws HibernateException, SQLException {
        st.setObject(
                index,
                value != null ?
                        ((Enum) value).name() :
                        null,
                Types.OTHER
        );
    }
}

WeatherEnum

public enum WeatherEnum {
    sunny, cloudy, stormy, rainy;
}

PgSQL Script to create enum:

CREATE TYPE WeatherEnum AS ENUM ('sunny','rainy','cloudy','stormy');
