这是我的代码，这里的返回类型是列表，但列表转换为数组，返回类型更改为字符串 

    @RequestMapping(value =Array( "/StandardChange.html"))
    @ResponseBody
    def  findDivisionOfStandards(@RequestParam  divisionid:Long):List[Division] ={

     var division:List[Division]= null
     if (divisionid != null) {

        division  = divisionService.findDivisionByStandardId(divisionid)            
    }       
     division  
    }

我试过了，但这不起作用

返回类型将List更改为String并将值更改为List到Json Array

  @RequestMapping(value =Array( "/StandardChange.html"))
  @ResponseBody
    def  findDivisionOfStandards(@RequestParam  divisionid:Long):String ={

      var division:List[Division]= null

      if (divisionid != null) {

           division  = divisionService.findDivisionByStandardId(divisionid)         

        }   
       var divisionjsonArray=  division.toArray     **json convert should be here**

      divisionjsonArray
    }
