Question

我决定将JPA应用程序迁移到MongoDB，并在某些时候将模型转换为使用JPA和MongoDB批注进行批注的分类，如下所示：

import lombok.*;
import lombok.extern.slf4j.Slf4j;
import org.springframework.data.mongodb.core.mapping.Document;
import org.springframework.data.solr.core.mapping.Indexed;

import javax.persistence.*;
import java.util.ArrayList;
import java.util.List;

@Entity
@Setter
@Getter
@Builder(toBuilder = true)
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode(of = {"name"})
@ToString(exclude = {"ownerShare", "shareVotes"})
@Slf4j
@Document
public class Share {
    @Id
    @GeneratedValue
    //private Long id;
    private String id;

    @Version
    private Long version;

    @Indexed
    @Access(AccessType.PROPERTY)
    private String name;

    @Column(unique = true)
    public void setName(String name) {
        //log.info("Setter Name is called");
        this.name = name;
        try {
            this.setNumber(number = name != null ? Integer.parseInt(name.replaceAll("[^0-9]", "")) : null);
        }
        catch (java.lang.NumberFormatException e)
        {
            this.setNumber(0);
        }
    }



    @Access(AccessType.PROPERTY)
    private Integer number;

    public void setNumber(Integer number) {
        if (number == null) {
        } else {
            log.trace(number + " number passed to store");
            this.number = number;
        }
    }

    private long shareNominator;
    private long shareDenominator;
    private double shareValue;

    @Indexed
    private Double area;
    private ShareType type;

    private int floor;

    @OneToMany(mappedBy = "share")
    private List<OwnerShare> ownerShare = new ArrayList<>();

    public enum ShareType {
        RESIDENTAL,
        NONRESIDENTAL
    }

    @OneToMany(fetch = FetchType.LAZY, mappedBy = "share")
    private List<ShareVote> shareVotes;

    private Boolean active;

   }

我已添加了所需的MongoDB注释，如app config java类中所述：https://spring.io/guides/gs/accessing-data-mongodb/

并为Spring Data定义了MongoDB存储库，如下所示（仅有预期的行为只是为了保存对象）：

import com.github.eljah.saylaw.model.Share;
import org.springframework.data.mongodb.repository.MongoRepository;

import java.util.List;

/**
 * Created by eljah32 on 3/20/2019.
 */
public interface ShareMongoRepository extends MongoRepository<Share, String> {
//    List<Share> findByActiveIsTrue();
//    List<Share> findByActiveIsFalse();
//    List<Share> findAllByOrderByNumberAscNameAsc();
//    List<Share> findAllByOrderByNumberAsc();
//    List<Share> findAllByOrderByNameAsc();
}

我已经通过@Autowired在服务类中添加了仓库，并试图运行该应用程序。但是，由于与JPA相关的此错误，我没有初始化我的bean：

有什么想法吗？

PS。 pom.xml包含版本的部分：

Answer 1

我已经意识到，通过添加

可以解决问题。

@SpringBootApplication
@EnableMongoRepositories(basePackages = "com.github.eljah.saylaw.mongo")
@EnableJpaRepositories(basePackages =  "com.github.eljah.saylaw.repository")

进入appconfig java类。

在此修复程序之前，我只有@EnableMongoRepositories，对于JPA没有任何特定的东西，因为最初它仅在开始迁移之前才与JPA一起使用。

在Spring Boot应用程序的模型类中同时使用JPA和MongoDB批注的问题
