可复用的模型设计考虑

BlogCY — Fri, 04 Aug 2006 04:52:00 GMT

公司�l�常更换框架�Q�好不容易写好的业务模型�l�常要推倒重来�?br />为此考虑��业务模型独立出来，不受框架的媄响�?br />具体考虑如下�Q?br />1.接口定义
DBConnection.java
public interface DBConnection {
PreparedStatement prepareStatement(String aSql);
....
void free();
void commit();
void rollback();
}
DBContext.java
public interface DBContext {
DBConnection newDBConnection();
}
2.模型实现
public class ActualFlow {
DBContext dbContext=null;
public ActualFlow() {
}
public void init(DBContext aContext){
    dbContext=aContext;
}
public int calculate(String aBranchId,String aYear,String aMonth,String aUserId){
    int iRtn=-1
    PreparedStatement objState=null;
    ResultSet objSet=null;
    DBConnection objCon=null;
    try {
      objCon=dbContext.newDBConnection();
      objState=objCon.prepareStatement("具体的sql语句");
      //业务模型操作......

    }
    catch (Exception ex) {
      ex.printStackTrace();
      iRtn=-1;
    }finally{
      if (objSet!=null) {
        try {
          objSet.close();//关闭�l�果集合
        }
        catch (Exception ex) {
          ex.printStackTrace();
        }
      }
      if (objState!=null) {
        try {
          objState.close();//关闭statement
        }
        catch (Exception ex1) {
          ex1.printStackTrace();
        }
      }
      if (objCon!=null) {
        objCon.free();//释放�q�接
      }
    }
    return iRtn;
}
}
3.在具体的开发框架下�?br />   定义EAPDBContext 实现 DBContext
   如下方式复用模型�Q?br />      ActualFlow objActualFlow=new ActualFlow();
    objActualFlow.init(new EAPDBContext("actualFlow"));
      int i=objActualFlow.calculate(this.m_branchID,this.m_year,this.m_month);

不知道是否合理，先练习练�?/p>

javascript 字符串的Iterator函数

BlogCY — Sat, 29 Jul 2006 02:11:00 GMT

//字符串的Iterator函数
//例子:
//var it=new StringIterator("a,b,c,d",",");
//while(it.hasNext()){
// alert(it.next());
//}

1function StringIterator(aStr,aSep){
2  this.origin=aStr;
3  this.sep=aSep;
4  this.remain=aStr;
5  this.nextStr=null;
6  this.hasNext=hasNext;
7  function hasNext() {
8   var iIndex=0;
9   if(this.remain==null){this.remain='';}
10   if(this.remain==''){
11     this.nextStr=null;
12     return false;
13   }
14   iIndex=this.remain.indexOf(aSep);
15   if(iIndex<0){
16     this.nextStr=this.remain;
17     this.remain='';
18   }else{
19     this.nextStr=this.remain.substring(0,iIndex);
20     this.remain=this.remain.substring(iIndex+this.sep.length);
21   }
22   return true;
23  }
24  this.next=next;
25  function next() {
26   var strRtn=this.nextStr;
27   this.nextStr=null;
28   return strRtn;
29  }
30}
