我需要一个例子来排序ace中的列:dataTable,我不知道如何使用sortBy + sortFunction。 感谢

所以我的朋友找到了解决方案:

在collectionBean中:

private Comparator<String> vNoComparator = new Comparator<String>(){ 

         public int compare(String iRec1, String iRec2){
              if(iRec1==null || iRec2==null)
              {
                    if(iRec1==null && iRec2==null)
                          return 0;
                    if(iRec1==null)
                          return -1;
                    return 1;
              } 

              long vNumber1=  Long.parseLong(iRec1) ;
              long vNumber2= Long.parseLong(iRec2);
              if(vNumber1>vNumber2)
                    return 1;
              else if(vNumber1<vNumber2)
                    return -1;
              else        
                    return 0; 
        }
  };

Comparator的类型是我们排序的属性的类型,在这种情况下,ARecordNo类型是String

public Comparator<String> getvNoComparator() {
        return vNoComparator;
  }
  public void setvNoComparator(Comparator<String> vNoComparator) {
        this.vNoComparator = vNoComparator;
  }

在.xhtml中:

  <ace:dataTable
  value="#{eITDocumentsCollectionBean.AEITDocumentsItems}"
  var="eITDocumentsItemBean" …..
  <ace:column
  headerText="#{eITDocumentsCollectionBean.ARecordNumberColumnName}"
  sortBy="#{eITDocumentsItemBean.ARecordNo}" 
  sortFunction="#{eITDocumentsCollectionBean.vNoComparator}">

ARecordNo = ItemBean中要按其排序的属性 vNoComparator =我创建的比较器
