Spring security spring安全删除用户失败

我正在使用SpringSecurity运行一个1.1.4.0版本的SpringBoot应用程序。我有基本的Spring用户和权限表和实体：

@Entity
@Table(name = "USERS")
public class User implements UserDetails {

    @Id
    private String username;

    @Column(nullable = false)
    private String password;

    private boolean enabled;
    private boolean accountNonExpired;
    private boolean accountNonLocked;
    private boolean credentialsNonExpired;
    private String companyName;

    @OneToMany(mappedBy = "username", fetch = FetchType.EAGER, orphanRemoval = true)
    @Cascade({org.hibernate.annotations.CascadeType.ALL})
    private Set<Authorities> roles = new HashSet<Authorities>();

/// getters and setters
}


@Entity
public class Authorities {

    @Id
    private String username;
    private String authority;
    /// getters and setters
}

当我尝试删除一个用户时，我得到一个错误：

org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint ["IX_AUTH_USERNAME: PUBLIC.AUTHORITIES FOREIGN KEY(USERNAME) REFERENCES PUBLIC.USERS(USERNAME) ('testUser')"; SQL statement:
delete from USERS where username=? [23503-172]]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement

我认为我的映射是错误的，但老实说，我不知道在哪里

更新： 基于良好的反馈，我现在有以下几点：

@Entity
@Table(name = "USERS")
public class User implements UserDetails {

    @Id
    private String username;

    @Column(nullable = false)
    private String password;

    private boolean enabled;
    private boolean accountNonExpired;
    private boolean accountNonLocked;
    private boolean credentialsNonExpired;
    private String companyName;

    @ElementCollection(fetch=FetchType.EAGER)
    @CollectionTable(name="Authorities", joinColumns=@JoinColumn(name="username"))
    @Column(name="authority")
    private Set<String> roles = new HashSet<String>();

// getters & setters
}

@Repository
public interface UserRepository extends CrudRepository<User, String> {

    User findUserByUsername(String username);

    void delete(String username);

    List<User> findAll();
}

及

我正在使用H2，我在liquibase中创建和种子，如下所示：

<createTable tableName="Users">
    <column name="username" type="VARCHAR_IGNORECASE(50)"/>
    <column name="password" type="VARCHAR_IGNORECASE(500)"/>
    <column name="companyName" type="VARCHAR_IGNORECASE(500)"/>
    <column name="enabled" type="boolean"/>
    <column name="accountNonExpired" type="boolean"/>
    <column name="accountNonLocked" type="boolean"/>
    <column name="credentialsNonExpired" type="boolean"/>
</createTable>

<createTable tableName="Authorities">
    <column name="username" type="VARCHAR(50)">
        <constraints primaryKey="true" nullable="false"
                     foreignKeyName="ix_auth_username" references="Users(username)" deleteCascade="true"/>
    </column>
    <column name="authority" type="VARCHAR_IGNORECASE(500)"/>
</createTable>

删除这个类。请记住，实体与表不同。在用户类中使用以下映射：

@ElementCollectionfetch=FetchType.EAGER @CollectionTablename=权限，joinColumns=@JoinColumnname=用户名 @Columnname=权限 私人机构；

此外，您还可以在外键上添加DELETE CASCADE。

您是否尝试先删除用户的权限，然后再删除用户？是的，我也尝试过，但它会抛出referentialingtegrityexception或其他内容。要解决此问题，使用delete的实现更新问题以及如何创建表。我已使用当前代码状态更新了问题。有什么想法吗？我对liquibase不太了解，但你似乎把主键和外键弄混了。authority表的主键必须跨越用户名和权限。否则，一个用户只能有一个角色。我不确定是否遵循。如果我没有实体，我如何为用户保留权限，例如：boldAuthorities Authorities=newauthorities USER.getUsername，USER；user.getRoles.addauthorities；粗体如果我将权限添加为字符串，这些权限是否会被持久化？是的，当用户对象被持久化时，它们将被持久化。我需要做什么来删除用户的权限？我在上面提出了您的建议，并在username列中添加了一个deleteCascade=true的约束。但是当我删除一个用户时，我不认为权限也会被删除，因此我可以直观地验证记录。删除该用户时，权限表中的相关行应该自动删除。在外键就位的情况下，不要担心。如果我创建了一个用户，然后将其删除，并尝试重新创建相同的用户名，我会得到一个异常：boldcannotexecutestatement；SQL[n/a]；约束[PUBLIC.AUTHORITIESUSERNAME上的主键A；SQL语句：插入到Authorities用户名中，权限值？，？[23505-172]；嵌套异常为org.hibernate.exception.ConstraintViolationException:无法执行stateme bold，因此我认为权限表记录未被正确删除
