如何将bean arraylist 用于另一个带有hibernate 注释的bean？

Question

我想将一个bean arraylist 用作另一个bean 的字段。我得到了“mappedBy reference an unknown target entity 属性” 错误。

我有两个 class 1. Logs 2. Log 并且所有 Logs 元素都比 Log 多了一个。 log.executionid可以是多条记录，但所有logs.executionid必须不同

@Entity
@Table(name = "t_logs")
public class Logs {

@Id
@Column(name = "executionid")
private String executionId;

@Column(name = "sentdate")
@Temporal(TemporalType.TIMESTAMP)
private Date sendDate;

@Column(name = "exceptionmessage")
private String exceptionMessage;

@OneToMany(mappedBy = "executionid", cascade = CascadeType.ALL)
private List<Log> loglist;
}



@Entity
@Table(name = "t_log")
public class Log {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private long id;

@Column(name = "executionid")
private String executionId;

@Column(name = "startdate")
@Temporal(TemporalType.TIMESTAMP)
private Date startDate;

@Column(name = "enddate")
@Temporal(TemporalType.TIMESTAMP)
private Date endDate;
}

Answer 1

mappedBy = "executionid" 是错误的。

此字段必须引用 "property"。这就是错误所说的。

必须mappedBy = "executionId"，字段名class而不是列名

Answer 2

，这是正确的答案

日志table；

    @OneToMany(mappedBy = "logs", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    private List<Log> loglist;

日志table;

    @ManyToOne
    @JoinColumn(name = "executionid")
    private Logs logs;
