我尝试了以下代码

@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

    var updatedAt: String = ""

    @Serializedname("author_association")
    @Expose
    @ColumnInfo(name = "author_association")
    var authorAssociation: String = ""


}

用户类别

class User {

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

    @Serializedname("login")

    @ColumnInfo(name = "login")
    var login: String = ""


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

    @Serializedname("avatar_url")

    @ColumnInfo(name = "following_url")
    var followingUrl: String = ""

    @Serializedname("gists_url")
    @Expose
    @ColumnInfo(name = "gists_url")
    var gistsUrl: String = ""

    @Serializedname("starred_url")
    @Expose
    @ColumnInfo(name = "starred_url")
    var starredUrl: String = ""

    @Serializedname("subscriptions_url")
    @Expose
    @ColumnInfo(name = "subscriptions_url")
    var subscriptionsUrl: String = ""

    @Serializedname("organizations_url")
    @Expose
    @ColumnInfo(name = "organizations_url")
    var organizationsUrl: String = ""

    @Serializedname("repos_url")
    @Expose
    @ColumnInfo(name = "repos_url")
    var reposUrl: String = ""

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

    @Serializedname("received_events_url")
    @Expose
    @ColumnInfo(name = "received_events_url")
    var receivedEventsUrl: String = ""

    @Serializedname("type")
    @Expose
    @ColumnInfo(name = "type")
    var type: String = ""

    @Serializedname("site_admin")
    @Expose
    @ColumnInfo(name = "site_admin")
    var siteAdmin: Boolean = false
}

我想在房间数据库中保存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，请告诉我。提前致谢。您的努力将不胜感激。

解决方法

您可以检查this Medium article，看看是否有帮助。这不是您的确切用例，但确实处理了一系列嵌套对象。
