关于query自定义条件查询~

自定义条件就要写自己的查询条件

首先定义

  
    

   
     
   
     private
   
      List
   
     <
   
     String
   
     >
   
      conditions
   
     =
   
     new
   
      ArrayList
   
     <
   
     String
   
     >
   
     ();
  
    

用来存放你的条件

代码

   
     

    
      
    
      public
    
       
    
      void
    
       searchOrder(){
 
    
      //
    
      String EJBQL = "select customerOrder from CustomerOrder customerOrder";
    
      

    
       
 
    
      if
    
      (
    
      this
    
      .timeBegin
    
      !=
    
      null
    
      ){
 conditions.add(
    
      "
    
      customerOrder.timeCreated>=#{customerOrderList.timeBegin}
    
      "
    
      );
 }
 
 setEjbql(EJBQL);
 setRestrictionExpressionStrings(conditions);
 setMaxResults(
    
      25
    
      );
 
    
      this
    
      .refresh();
 
    
      //
    
      return this.getResultList();
    
      

    
       
 }
