存在Hibernate问题的PostgresSQL和JavaSpringBoot AP之间的链接枚举

Question

如何解决这个问题？

我的代码

流星实体

//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;
    }

   .
   .
   .

}

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
            );
        }
    }
}

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

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

我准备了一个复制品。https://github.com/ozkanpakdil/spring-examples/tree/master/postgresql-test一个简单的示例来展示它是如何工作的。您可以从http：//localhost:8080/swagger-ui.html访问swagger。swagger看起来在SB2.2中有问题

下面是示例帖子

curl -X POST "http://localhost:8080/api/v1/meteo" -H  "accept: */*" -H  "Content-Type: application/json" -d "{  \"weather\": \"rainy\"}"

这就是你如何

curl -X GET "http://localhost:8080/api/v1/meteo" -H  "accept: application/json"
