页面在多系统应用中同步

业务场景：

         用户去银行营业厅办理的业务时 需要在预处理机上面填写代办业务信息或者之前在 网上预约系统填写过就可以到柜员直接办理业务。

涉及到预处理机 和 网上预约系统 两个系统，如何在开发的时候同步它们共同的业务数据也就是页面可以提供开发效率。

以及在每个系统中提取公用页面比如 formEdit.jsp (填写页面)与formConfirm.jsp  (显示页面)

 

 

以fromEdit.jsp为例：

在公用页面fromEdit.jsp页面加入jsp定义的标签<mct:form ，formConfig.template 没不同的页面模板，formObject不同模板的业务数据

 

 

<div class="centerdd" style="width:780px">
			<div id="formContent1">
			<c:if test="${!empty(formObject)}">
			<mct:form formObject="${formObject}" template="${formConfig.template}"/>
			</c:if>
			</div>
		 
		</div>

 

<mct:form 定义：

 

/**
 * 表单模板输入标签。该标签输出基于 FreeMarker 的模板。
 * 
 *   
 */
public class FormTemplateTag extends TagSupport
{
    /**
     * 表单对象
     */
    Object formObject;
    
    /**
     * 模板名称

    String template; 
    
    /**

                tempFormObject = realObj;
            }
            
            if (!(tempFormObject instanceof FormContentObject))
                throw new RuntimeException("Invalid form object: A FormContentObject is expected.");

        }

    }

    //字典数据
