JOOQ + JPA实体

Question

我是JOOQ库的新手，有一件事让我很感兴趣。我首先在JOOQ上实现了CRUD服务，之后我试图避免一些重复的代码。为了达到这个目标，我添加了JPA仓库，并在我的由JOOQ生成的类中添加了@Entity注解。现在，我仍然希望在某些情况下使用JOOQ (使用筛选、排序和分页来查询列表)。但是出现了一些错误，现在在JOOQ发出select请求之后，我可以在我的类的属性中看到空值。

我通过筛选器获得了正确的实体计数，但映射后类的属性为空。在这种情况下，是映射错误还是我不能同时使用JOOQ和JPA？

我的所有实体的抽象类(正如我所说的，为了避免重复代码，我重构了一些代码，现在使用泛型)：

@MappedSuperclass
public abstract class AbstractServiceEntity {

private Integer id;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Integer getId() {
    return id;
}

public void setId(Integer id) {
    this.id = id;
}
}

我的JPA类(由JOOQ生成)：

/**
* This class is generated by jOOQ.
*/
@SuppressWarnings({ "all", "unchecked", "rawtypes" })
@Entity
@Table(schema = "ref", name = "account")
public class Account extends AbstractServiceEntity implements Serializable {

   private static final long serialVersionUID = -162537472;

private Integer       id;
private Integer       transitId;
private Integer       partnerId;
private String        currencyCode;
private String        descr;
private Long          inCredit;
private Long          balanceLimit;
private Long          outCredit;
private LocalDateTime createdAt;
private LocalDateTime updatedAt;
private Integer       transitPartnerId;

public Account() {}

public Account(Account value) {
    this.id = value.id;
    this.transitId = value.transitId;
    this.partnerId = value.partnerId;
    this.currencyCode = value.currencyCode;
    this.descr = value.descr;
    this.inCredit = value.inCredit;
    this.balanceLimit = value.balanceLimit;
    this.outCredit = value.outCredit;
    this.createdAt = value.createdAt;
    this.updatedAt = value.updatedAt;
    this.transitPartnerId = value.transitPartnerId;
}

public Account(
    Integer       id,
    Integer       transitId,
    Integer       partnerId,
    String        currencyCode,
    String        descr,
    Long          inCredit,
    Long          balanceLimit,
    Long          outCredit,
    LocalDateTime createdAt,
    LocalDateTime updatedAt,
    Integer       transitPartnerId
) {
    this.id = id;
    this.transitId = transitId;
    this.partnerId = partnerId;
    this.currencyCode = currencyCode;
    this.descr = descr;
    this.inCredit = inCredit;
    this.balanceLimit = balanceLimit;
    this.outCredit = outCredit;
    this.createdAt = createdAt;
    this.updatedAt = updatedAt;
    this.transitPartnerId = transitPartnerId;
}

我的方法是从DB中提取实体：

@Repository
@RequiredArgsConstructor
public class JooqAccountRepository {

private final DSLContext jooq;

public List<Account> findAll(Condition filterCondition, SortField[] sortFields, Integer partnerId, Integer limit, Integer offset) {
    return jooq.selectFrom(ACCOUNT)
            .where(ACCOUNT.PARTNER_ID.equal(partnerId))
            .and(filterCondition)
            .orderBy(sortFields)
            .limit(limit)
            .offset(offset)
            .fetchInto(Account.class);
}

public Integer findAccountsCount(Integer partnerId) {
    return jooq.selectCount().from(ACCOUNT)
            .where(ACCOUNT.PARTNER_ID.equal(partnerId))
            .fetchOne(0, Integer.class);
}

}

作为我搜索的结果-我在Account类中犯了一个注释错误。如果你想同时使用这些框架，你应该在实体属性上使用@Column，或者以不同的方式设置你的jooq的codegen插件) This resource was usefull for me
