查询方法公共摘要的验证失败

Question

希望你们一切都好，

我遇到了一些我无法找到解决方法的问题 或者如何解决它

如果我想进行查询，这可能是可能的，但我想尝试这种方式，如果无法通过这种方式，请告诉我 我正在使用 JPARepository

public Posts findByIdAndCommonFieldActive(int id, boolean active);

我的 POST 实体类

@Entity
@Table(name="post")
public class Posts implements Serializable {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private int id;
    private String title;
    private String description;
    private String content;

    @Embedded
    private CommonField commonField;

    @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.LAZY, mappedBy="post")
    private List<Comments> comments = new ArrayList<Comments>();

   //getter and setter
}

我的常见领域课程

@Embeddable
public class CommonField {

    private boolean isActive;
    private Date createdDate;
    private Date modifiedDate;
    private int createdBy;
    private int modifiedBy;

    public CommonField() {
        // TODO Auto-generated constructor stub
    }


    public CommonField(boolean isActive, Date createdDate, Date modifiedDate, int createdBy, int modifiedBy) {
        super();
        this.isActive = isActive;
        this.createdDate = createdDate;
        this.modifiedDate = modifiedDate;
        this.createdBy = createdBy;
        this.modifiedBy = modifiedBy;
    }

    /// Getter and Setter

}

我得到的错误

但是请告诉我最好的方法 谢谢

Answer 1

变化

public Posts findByIdAndCommonFieldActive(int id, boolean active);

到

public Posts findByIdAndCommonFieldIsActive(int id, boolean isActive);

应该可以解决你的问题。
