JavaFX - 将LinkedHashMap绑定到ComboBox(JavaFX - Bind LinkedHashMap to ComboBox)

 我有LinkedHashMap与来自数据库的数据。 
 
private Map<Integer, String> linkedHashMap = new LinkedHashMap<>();
eg: 1, Value1
    2, Value2
    etc.
 
 我能够将这个LinkedHashMap与ComboBox绑定为Observable值吗？ 
 
 到目前为止，我已经填充了这个ComboBox这个代码。 
 
ComboBox.getItems().addAll(this.linkedHashMap.values());
 
 问题是如果我需要重新加载值，我必须清除所有ComboBox值，并且必须再次导入值。 

I have LinkedHashMap with data from database.
 
private Map<Integer, String> linkedHashMap = new LinkedHashMap<>();
eg: 1, Value1
    2, Value2
    etc.
 
Am I able to bind this LinkedHashMap with ComboBox as Observable values?
 
So far, I have filled this ComboBox this code.
 
ComboBox.getItems().addAll(this.linkedHashMap.values());
 
Problem is if I need to reload values I have to clear all ComboBox values and I have to import values again.
