bo物件：

注：

jaxb只會序列化 public 的方法 ，若屬性宣告為public，且宣告 @XmlElement(name = "name") ，則需要在該屬性get方法上宣告@XmlTransient，表示不將get方法序列化成xml元素，否則會報重複屬性序列化。或者將屬性改為private ，將@XmlElement(name = "name")放置在get方法上。

其二：若尋在 屬性中有 Date型別，需要繼承XmlAdapter<String, Date>類，並重載2個方法後，在bo物件處使用@XmlJavaTypeAdapter(JaxbDateSerializer.class) 進行序列化。
