Question

无法启动Spring Boot应用程序。

存储库及其相关域

import com.vircosolutions.mobileapi.domain.Awards;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;

@RepositoryRestResource(exported = false)
public interface AwardsRepository extends JpaRepository<Integer, 
Awards> {
}

域

import lombok.Getter;
import lombok.Setter;
import javax.persistence.*;
import java.io.Serializable;
import java.util.Date; 
import java.util.Objects;

@Getter
@Setter
@Entity
@Table(name = "awards")
public class Awards implements Serializable {


private static final long serialVersionUID = -170576994834461289L;


@Id
@Column(name = "id_awards", nullable = false)
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;

@ManyToOne
@JoinColumn(name = "id_user", nullable = false)
private Users user;

@Column (name = "rating", nullable = false)
private float rating;

@Column (name = "award_type", nullable = false)
private String awardType;

@Column (name = "award_date", nullable = false)
private Date awardDate;

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;
    Awards awards = (Awards) o;
    return id == awards.id &&
            Float.compare(awards.rating, rating) == 0 &&
            Objects.equals(user, awards.user) &&
            Objects.equals(awardType, awards.awardType) &&
            Objects.equals(awardDate, awards.awardDate);
}

@Override
public int hashCode() {

    return Objects.hash(id, user, rating, awardType, awardDate);
}

@Override
public String toString() {
    return "Awards{" +
            "id=" + id +
            ", user=" + user +
            ", rating=" + rating +
            ", awardType='" + awardType + '\'' +
            ", awardDate=" + awardDate +
            '}';
}

}

主应用程序文件看起来像

@EnableSpringDataWebSupport
@SpringBootApplication
public class MobileApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return super.configure(builder);
    }

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

我进行了很多调试，但无法找到根本原因。 Stach跟踪如下。如果您需要任何其他文件和代码，则可以提供。任何帮助将不胜感激。

Answer 1

您以错误的顺序指定了通用类型，因此错误Not a managed type: class java.lang.Integer

尝试：

@RepositoryRestResource(exported = false)
public interface AwardsRepository extends JpaRepository<Awards, Integer> {
}

顺便说一句，并且遵循命名约定，您还应该将实体Awards重命名为Award，并相应地重命名存储库。
