springMVC的請求方法中處理多個mybatis方法，到某個方法中斷了:BindingException:has an unsupported return type

例如：

   
   
   
           

    
    
    
            
@ResponseBody
    
    
    
            
 @RequestMapping(value = "toRequestDeleteDome", method = RequestMethod.POST)
    
    
    
            
 public ConverntReturnList deleteSomeHandler(@RequestParam("del_items[]") Integer[] array, @RequestParam("show_page") Integer curPageNum) {
    
    
    
            

    
    
    
            
 System.out.println(array.toString());
    
    
    
            

    
    
    
            
 productionDao.toDeleteYourSelction(array);
    
    
    
            

    
    
    
            
 PageHelper.startPage(curPageNum, 10);
    
    
    
            
 List<Production> list = productionDao.getAllProduction();
    
    
    
            
 int allResultPages = ((Page) list).getPages();
    
    
    
            
 int curResultPage = ((Page) list).getPageNum();
    
    
    
            

    
    
    
            
 return new ConverntReturnList(curResultPage, allResultPages, list);
    
    
    
            

    
    
    
            
 }
   
   
   
           

在運行 productionDao . toDeleteYourSelction ( array );之后，程序就死了，沒有運行下去，報錯如下：

mybatis的處理出錯：

  
  
  
          

   
   
   
           
org.apache.ibatis.binding.BindingException:
   
   
   
           

   
   
   
           
 Mapper method 'com.dao.ProductionMapper.toDeleteSelection' has an unsupported return type: class [Ljava.lang.Integer;
  
  
  
          

實際情況：

sql刪除沒有返回值：

   
   
   
           

    
    
    
            
<!--根據選擇刪除-->
    
    
    
            
 <delete id="toDeleteSelection" parameterType="arraylist">
    
    
    
            

    
    
    
            
 DELETE FROM ssh_info WHERE ssh_info.ID IN
    
    
    
            
 <foreach collection="array" item="item" open="(" separator="," close=")">#{item}</foreach>
    
    
    
            

    
    
    
            
 </delete>
   
   
   
           

但在mapper的dao中卻有返回值，這里出錯了

   
   
   
           

    
    
    
            
Integer[] toDeleteSelection(Integer[] arr);
   
   
   
           

應該改為：

   
   
   
           

    
    
    
            
void toDeleteSelection(Integer[] arr);
