Android 如何为房间数据库中的嵌套对象创建实体类

我从GitHub API得到以下响应

我试过下面的代码

@Entity(tableName = "issue_list_table")
class IssueModal {

    @SerializedName("id")
    @Expose
    @PrimaryKey
    var id: Int = 0

    @SerializedName("body")
    @Expose
    @ColumnInfo(name = "body")
    var body: String = ""

    @SerializedName("url")
    @Expose
    @ColumnInfo(name = "url")
    var url: String = ""

    @SerializedName("repository_url")
    @Expose
    @ColumnInfo(name = "repository_url")
    var repositoryUrl: String = ""

    @SerializedName("labels_url")
    @Expose
    @ColumnInfo(name = "labels_url")
    var labelsUrl: String = ""

    @SerializedName("comments_url")
    @Expose
    @ColumnInfo(name = "comments_url")
    var commentsUrl: String = ""

    @SerializedName("events_url")
    @Expose
    @ColumnInfo(name = "events_url")
    var eventsUrl: String = ""

    @SerializedName("html_url")
    @Expose
    @ColumnInfo(name = "html_url")
    var htmlUrl: String = ""

    @SerializedName("node_id")
    @Expose
    @ColumnInfo(name = "node_id")
    var nodeId: String = ""

    @SerializedName("number")
    @Expose
    @ColumnInfo(name = "number")
    var number: Int = 0

    @SerializedName("title")
    @Expose
    @ColumnInfo(name = "title")
    var title: String = ""

    @SerializedName("user")
    @Expose
    @Embedded
    var user: User = User()

    @SerializedName("state")
    @Expose
    @ColumnInfo(name = "state")
    var state: String = ""

    @SerializedName("locked")
    @Expose
    @ColumnInfo(name = "locked")
    var locked: Boolean = false

    @SerializedName("comments")
    @Expose
    @ColumnInfo(name = "comments")
    var comments: Int = 0

    @SerializedName("created_at")

用户类

我想在room数据库中保存GitHub api响应，但我不知道如何为嵌套对象创建实体类

如果需要更多信息，请务必让我知道。提前谢谢。感谢您的努力。

您可以检查一下，看看这是否有帮助。这不是您确切的用例，但它确实处理嵌套对象的列表

class User {

    @SerializedName("id")
    @Expose
    @PrimaryKey
    @ColumnInfo(name = "user_id")
    var id: Int = 0
