Spring boot-从两个模型文件中获取常见细节

我有两个模型文件

1. UserDetails.java

    @Id
    @Column(name = "id")
        private String id;

    @Column(name = "firstname")
        private String firstname;
    
    @Column(name = "lastname")
    private String lastname;
    
    @Column(name = "email")
    private String email;
    
    @Column(name = "password")
    private String password;

        and getter setters...

2.自定义用户细节.java

        @Id
    @Column(name = "id")
        private String id;

    @Column(name = "email")
    private String email;
    
    @Column(name = "password")
    private String password;

         and getter setters...

在UserDetailsDaoImpl.java中

在获取用户详细信息时-在获取详细信息后，需要使用CustomUserDetails减少详细信息（意味着在该对象中，我只有id、电子邮件和密码）
