邹丰羽
2023-03-14

使用Spring Boot 1.4.0和MySql 5.7

我有两个table并且它是单向的@manytomany，但是在角色的父端，我想删除权限hibernate会自动删除它自己和link-table记录：

>

  • 权限 

    @Entity
public class Permission {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(unique = true)
    private String name;

    //...Getter and Setter
}

    @Entity
public class Role {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(unique = true)
    private String name;

    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    private final Collection<Permission> allowedPermissions = new ArrayList<>();

    //...Getter and Setter
}

    出现此异常是因为您试图删除permission表上的permission记录，但在此之前没有删除联接表上的匹配记录。

    因此，假设在permission表上有一个主键为203的记录，您需要删除联接表上的一个forgien键为203的记录。

    顺便问一下，您的@jointable注释在哪里？我在你的代码里看不到。

    @ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
