如何创建数据类实现特定于Spring Secuirty的UserDetails [英] How to create a data class implements Spring Secuirty specific UserDetails

问题描述

我正在尝试将一些spring-webflux示例代码迁移到Kotlin.

I am trying to migrate some spring-webflux sample codes to kotlin.

目前，我想转换 Spring Data Mongo 样本到Kotlin.有一个User，原始的Data Mongo版本看起来是:

Currently I want to convert my Spring Data Mongo sample to kotlin. There is a User, the original Data Mongo version looks:

@Data
@ToString
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Document
class User implements UserDetails {

    @Id
    private String id;
    private String username;
    private String password;

    @Builder.Default()
    private boolean active = true;

    @Builder.Default()
    private List<String> roles = new ArrayList<>();

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return AuthorityUtils.createAuthorityList(roles.toArray(new String[roles.size()]));
    }

    @Override
    public boolean isAccountNonExpired() {
        return active;
    }

    @Override
    public boolean isAccountNonLocked() {
        return active;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return active;
    }

    @Override
    public boolean isEnabled() {
        return active;
    }

}

UserDetails界面包括一些getXXX和isXXX方法，如何将override添加到kotlin的username和password属性中?

The UserDetails interface includes some getXXX and isXXX methods, how to add override to the username and password proerpties in kotlin?

顺便说一句:目前，我在kotlin版本UserDetails /com/example/demo/User.kt"rel =" nofollow noreferrer>在此处检查:

BTW: Currently I removed UserDetails in the kotlin version, check here:

@Document
data class User(
        @Id var id: String? = null,
        var username: String? = null,
        var password: String? = null,
        var active: Boolean = true,
        var roles: List<String> = ArrayList()
)

更新:如何向其中添加UserDetails接口?，新问题是使用销毁时不起作用.

The new problem is when use destruction, it does not work.

(id, username, password, active, roles) = <a user>

User位于

The User is located https://github.com/hantsy/spring-reactive-sample/blob/master/kotlin-gradle/src/main/kotlin/com/example/demo/User.kt . Currently I commented out the version implemented UserDetails. If I use the commented codes(User:UserDetails), the desstruction codes in Beans.kt will report errors in IDE. The errors occur on username and password: destructing declaration initializer of type User! must have a component2 function.

推荐答案

data class User(
        // inherits from UserDetails
        private val username: String,
        private val password: String,
        private val isEnabled: Boolean, //Disabled account can not log in
        private val isCredentialsNonExpired: Boolean, //credential can be expired,eg. Change the password every three months
        private val isAccountNonExpired: Boolean, //eg. Demo account（guest） can only be online  24 hours
        private val isAccountNonLocked: Boolean, //eg. Users who malicious attack system,lock their account for one year
        private val authorities: Set<GrantedAuthority>, 

        // inherits from Tree.If the user is not a tree structure, can be ignored
        val id: Long,
        val parentId: Long? = null, 
        val lft: Int? = null, // preorder tree traversal algorithm
        val rgt: Int? = null, // preorder tree traversal algorithm
        val depth: Int? = null, // or levels
        val isLeaf: Boolean? = null, 
        val teamTotal: Int? = null, // The number of all subordinates
        val childrenTotal: Int? = null, //The number of all directly under the subordinate

        //Custom attributes
        val tenantId: Long, //We are the platform + tenant model
        val role: Set<Role>, // TENANT, SUBACCOUNT, DEFAULT_GROUP, MEMBER, GUEST
        val platform: Platform, // PC, IOS, ANDROID, WAP, INTERNAL
        val deviceToken: String? = null, //or machine code
        val ip: InetAddress //Inet4Address or Inet6Address
) : UserDetails, Tree(id, parentId) {
    override fun getUsername(): String = username
    override fun getPassword(): String = password
    override fun isEnabled(): Boolean = isEnabled
    override fun isCredentialsNonExpired(): Boolean = isCredentialsNonExpired
    override fun isAccountNonExpired(): Boolean = isAccountNonExpired
    override fun isAccountNonLocked(): Boolean = isAccountNonLocked
    override fun getAuthorities(): Set<out GrantedAuthority> = authorities
}
