ofbiz实战5——创建学期管理新建和编辑页面

下面是实现的学期管理的编辑界面（新增和编辑在一起了实现了）：

学期名称因为是主键，所以学期名称不能修改，只能作废，然后新增一个学期记录。

具体实现代码如下：

1. 配置controller.xml文件

<?xml version="1.0" encoding="UTF-8"?><site-conf xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xmlns="http://ofbiz.apache.org/Site-Conf" xsi:schemaLocation="http://ofbiz.apache.org/Site-Conf http://ofbiz.apache.org/dtds/site-conf.xsd">    <include location="component://common/webcommon/WEB-INF/common-controller.xml"/>    <include location="component://common/webcommon/WEB-INF/portal-controller.xml"/>    <description>Booking Component Site Configuration File</description>    <!-- Request Mappings -->    <request-map uri="main"><security https="true" auth="true"/><response name="success" type="view" value="main"/></request-map><!-- ================ Term Requests ================= -->    <request-map uri="FindTerm">        <security https="true" auth="true"/>        <response name="success" type="view" value="FindTerm"/>    </request-map>    <request-map uri="EditTerm">        <security https="true" auth="true"/>        <response name="success" type="view" value="EditTerm"/>    </request-map>    <request-map uri="createTerm">        <security https="true" auth="true"/>        <event type="service"  invoke="createTerm"/>        <response name="success" type="view" value="EditTerm"/>        <response name="error" type="view" value="EditTerm"/>    </request-map>    <request-map uri="updateTerm">        <security https="true" auth="true"/>        <event type="service"  invoke="updateTerm"/>        <response name="success" type="view" value="EditTerm"/>        <response name="error" type="view" value="EditTerm"/>    </request-map>    <!-- View Mappings --><view-map name="main" type="screen" page="component://booking/widget/booking/BookingScreens.xml#main"/>    <view-map name="FindTerm" type="screen" page="component://booking/widget/term/TermScreens.xml#FindTerm"/><view-map name="EditTerm" type="screen" page="component://booking/widget/term/TermScreens.xml#EditTerm"/></site-conf>

2. 配置TermScreens.xml

<screen name="EditTerm">        <section>            <actions>                <set field="titleProperty" value="TermManange"/>                <set field="headerItem" value="TermManange"/><!--<set field="termName" value="${parameters.termName}"/>--><entity-one entity-name="Term" value-field="term"/>            </actions>            <widgets>                <decorator-screen name="CommonBookingDecorator" location="${parameters.mainDecoratorLocation}">                    <decorator-section name="body"><container style="button-bar"><link target="FindTerm" text="${uiLabelMap.CommonBack}" style="buttontext"/></container>                        <screenlet title="${groovy: parameters.termName ? uiLabelMap.CommonEdit : uiLabelMap.CommonAdd}">                            <include-form name="EditTerm" location="component://booking/widget/term/TermForms.xml"/>                        </screenlet>                    </decorator-section>                </decorator-screen>            </widgets>        </section>    </screen>

3. 配置TermForms.xml

<form name="EditTerm" target="updateTerm" title="" type="single" header-row-style="header-row" default-table-style="basic-table" default-map-name="term" default-entity-name="Term"><alt-target use-when="term==null" target="createTerm"/><auto-fields-service service-name="updateTerm" map-name=""/><field use-when="term!=null" name="termName" title="${uiLabelMap.TermTermName}" tooltip="${uiLabelMap.BookingNotModification}." ><display/></field>        <field use-when="term==null" name="termName" title="${uiLabelMap.TermTermName}" required-field="true"><text size="20" maxlength="20" /></field>        <field name="beginTime" title="${uiLabelMap.TermBeginTime}" required-field="true"><date-time type="date" /></field><field name="endTime" title="${uiLabelMap.TermEndTime}" ><date-time type="date" /></field>        <field name="used" title="${uiLabelMap.TermUsed}">            <drop-down allow-empty="false" no-current-selected-key="Y"><option key="Y" description="${uiLabelMap.CommonYes}"/>                <option key="N" description="${uiLabelMap.CommonNo}"/>            </drop-down>        </field>        <field name="submitButton" title="${uiLabelMap.CommonSubmit}"><submit/></field>    </form>

4. 配置BookingUiLabels.xml

<property key="BookingNotModification">        <value xml:lang="en">BookingNotModification</value>        <value xml:lang="zh">不能修改</value>    </property>

BookingEntityLabels.xml配置暂时随便配一条记录，否则不能正常使用auto-fields-service标签。
这样页面就完成。感觉配置起来很简单，不用自己写太多的代码，只要配置好后，相关逻辑就自动实现了。

5.总结

学习了auto-fields-service标签的使用。

学习了field标签use-when和required-field属性的使用。

学习了下拉框控件和日期控件的使用，以及drop-down标签的allow-empty和no-current-selected-key属性的使用。

学会配置【后退】按钮。
