Question

我有3个表：数据库，表，字段。它们与一对多的关系相关联。数据库一对多表一对多字段。但是当我从jpa存储库调用save方法时，我得到了下一个异常。我也在检查stackowerflow的答案。在多对一关系上添加注释@NotFound（action = NotFoundAction.IGNORE）并没有帮助。

数据库类：

    @Entity
@Table(name = "data_base", schema = "dbmanager")
public class Database {
    @Id
    @NotNull
    @Column(name = "id_database", unique = true)
    private String id;

    @Column(name = "database_url")
    private String databaseUrl;

    @Column(name = "database_user")
    private String databaseUser;

    @Column(name = "database_password")
    private String databasePassword;

    @OneToMany(mappedBy = "database")
    private Set<Table> tables;
    }

表类：

    @Entity
    @javax.persistence.Table(name = "data_base_table", schema = "dbmanager")
    public class Table {
        @Id
        @NotNull
        @Column(name = "id_table", unique = true)
        private String id;

        @Column(name = "table_name")
        @NotNull
        private String name;

        @Column(name = "table_visible")
        private Integer visible;

        @ManyToOne(fetch = FetchType.LAZY)
        @NotFound(action = NotFoundAction.IGNORE)
        @JoinColumn(name = "id_database")
        private Database database = new Database();

        @OneToMany(mappedBy = "table")
        private Set<Field> fields;
}

字段类

 @Entity
@javax.persistence.Table(name = "table_field", schema = "dbmanager")
public class Field {
    @Id
    @NotNull
    @Column(name = "id_field", unique = true)
    private String id;

    @Column(name = "field_name")
    @NotNull
    private String name;

    @Column(name = "field_visible")
    @NotNull
    private Integer visible;

    @ManyToOne(fetch = FetchType.LAZY)
    @NotFound(action = NotFoundAction.IGNORE)
    @JoinColumn(name = "id_table")
    private Table table = new Table();
}
