我有一个Weather对象，我想使用JpaRepository添加到postgresql数据库。错误代码：不是托管类型：尽管在数据库中输入对象时存在所有依赖项。Service类是用@Service注解创建的，我试图通过它将对象输入到数据库中，但问题仍然存在。

package com.example.weather;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class WeatherApplication {
    public static void main(String[] args) {
        SpringApplication.run(WeatherApplication.class, args);
    }

}

package com.example.weather.model;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    @Column(name = "city")
    private String city;
    @Column(name = "temp")
    @JsonProperty("temp")

    @Column(name = "sunset")
    @JsonProperty("sunset")

    @JsonProperty("feels_like")

    @Column(name = "sunrise")
    @JsonProperty("sunrise")
    private int sunrise;
    @Column(name = "max_temp")
    @JsonProperty("max_temp")
    private int max_temp;

    public void Print(){
        System.out.println(String.format("id = %s\ncity = %s\ntemp = %s\nwind_speed = %s\nwind_degrees = %s\n" +
                "humidity = %s\nsunset = %s\nmin_temp = %s\ncloud_pct = %s\nfeels_like = %s\nsunrise = %s\nmax_temp = %s",
                id, city, temp, wind_speed, wind_degrees, humidity, sunset, min_temp, cloud_pct, feels_like, sunrise, max_temp));

spring.datasource.username=postgres
spring.datasource.password=12345

spring.jpa.database=postgresql
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL10Dialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

我添加了注解@EntityScan和@EnableJpaRepositories，但这并没有解决问题。
