在<af:table>拖出来的报表,给多个列增加合计信息。
第一步：在vo的实现类里增加如下代码
import java.util.HashMap;
import java.util.Map;
import oracle.jbo.server.ViewObjectImpl;
import org.codehaus.groovy.runtime.InvokerHelper;
// ---------------------------------------------------------------------
// --- File generated by Oracle ADF Business Components Design Time.
// --- Fri May 05 16:09:30 CST 2017
// --- Custom code may be added to this class.
// --- Warning: Do not modify method signatures of generated methods.
// ---------------------------------------------------------------------
public class VCzAssetLandView1Impl extends ViewObjectImpl {
/**
* This is the default constructor (do not remove).
*/
public VCzAssetLandView1Impl() {
}
private class AgrFuncHelper extends HashMap {
private String funcName;
public AgrFuncHelper(String funcName) {
super();
this.funcName = funcName;
}
public Object get(Object key) {
//Invoke private method
//of our DefaultRowSet (sum,count,avg,min,max)
//key is argument expression for the aggr funcion being called
//sum("Salary")
return InvokerHelper.invokeMethod(getDefaultRowSet(), funcName,
key);
}
}
public Map getSum() {
return new AgrFuncHelper("sum");
}
public Map getCount() {
return new AgrFuncHelper("count");
}
}
第二步：在jspx页面的对应column下，增加代码
<f:facet name="footer">
<af:panelGroupLayout id="pgl112" styleClass="AFStretchWidth"
layout="horizontal" halign="right"
inlineStyle="border-style:solid; border-width:1px;">
<af:outputText value="#{bindings.VCzAssetLandView1_1.viewObject.sum['AvgValue']}"
inlineStyle="font-weight:bold;" id="ot392">
<af:convertNumber type="currency" currencySymbol=""/>
</af:outputText>
</af:panelGroupLayout>
</f:facet>
整个column标签如下：
<af:column sortProperty="#{bindings.VCzAssetLandView1_1.hints.AvgValue.name}"
sortable="false"
headerText="#{bindings.VCzAssetLandView1_1.hints.AvgValue.label}"
id="c28">
<af:spacer width="10" height="10" id="s1"/>
<af:inputText value="#{row.bindings.AvgValue.inputValue}"
label="#{bindings.VCzAssetLandView1_1.hints.AvgValue.label}"
required="#{bindings.VCzAssetLandView1_1.hints.AvgValue.mandatory}"
columns="#{bindings.VCzAssetLandView1_1.hints.AvgValue.displayWidth}"
maximumLength="#{bindings.VCzAssetLandView1_1.hints.AvgValue.precision}"
shortDesc="#{bindings.VCzAssetLandView1_1.hints.AvgValue.tooltip}"
id="it46">
<f:validator binding="#{row.bindings.AvgValue.validator}"/>
<af:convertNumber type="currency" currencySymbol=""/>
</af:inputText>
<f:facet name="footer">
<af:panelGroupLayout id="pgl112" styleClass="AFStretchWidth"
layout="horizontal" halign="right"
inlineStyle="border-style:solid; border-width:1px;">
<af:outputText value="#{bindings.VCzAssetLandView1_1.viewObject.sum['AvgValue']}"
inlineStyle="font-weight:bold;" id="ot392">
<af:convertNumber type="currency" currencySymbol=""/>
</af:outputText>
</af:panelGroupLayout>
</f:facet>
</af:column>
运行结果如图：
