public class InitAppBean extends RealmObject {

　　新創建String類繼承RealmObject

public class RealmString extends RealmObject {
    private String val;

    public String getValue() {
        return val;
    }

    public void setValue(String value) {
        this.val = value;
    }
}

Realm 處理List<String> 問題 Type parameter 'java.lang.String' is not within its bound; should implement 'io.realm.RealmModel
