Struts result param詳細設置

Xml代碼  

<result type="json">
                <!-- 這裏指定將被Struts2序列化的屬性，該屬性在action中必須有對應的getter方法 -->
                <!-- 默認將會序列所有有返回值的getter方法的值，而無論該方法是否有對應屬性 -->
                <param name="root">dataMap</param>
                <!-- 指定是否序列化空的屬性 -->
                <param name="excludeNullProperties">true</param>
                <!-- 這裏指定將序列化dataMap中的那些屬性 -->
                <param name="includeProperties">
                    userList.*
                </param>
                <!-- 這裏指定將要從dataMap中排除那些屬性，這些排除的屬性將不被序列化，一半不與上邊的參數配置同時出現 -->
                <param name="excludeProperties">
                    SUCCESS
                </param>
