篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在Spring Boot应用程序中的模型类中同时使用JPA和MongoDB注释的问题相关的知识,希望对你有一定的参考价值。
我决定将JPA应用程序迁移到MongoDB,并且在某些时候,模型变成了带有JPA和MongoDB注释的分类,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;
}
我已经在app config java class:https://spring.io/guides/gs/accessing-data-mongodb/中添加了所需的MongoDB注释
并为此类Spring数据定义了MongoDB存储库(仅保存对象的唯一预期行为):
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();
}
我已经在服务类中通过@Autowired添加了repo并尝试运行该应用程序。但是由于与JPA相关的错误,我的bean没有被初始化:

有什么想法吗?
PS。包含版本的pom.xml部分:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
我已经意识到问题是通过添加修复的
@SpringBootApplication
@EnableMongoRepositories(basePackages = "com.github.eljah.saylaw.mongo")
@EnableJpaRepositories(basePackages = "com.github.eljah.saylaw.repository")
进入appconfig java类。
在此修复之前,我只有@EnableMongoRepositories并没有特定于JPA,因为最初它只在我开始迁移之前使用JPA。
