springMVC的请求方法中处理多个mybatis方法，到某个方法中断了: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);
    
    
    

    
    
    
 }
   
   
   

在运行 productionDao . toDeleteYourSelction ( array );之后，程序就死了，没有运行下去，报错如下：

mybatis的处理出错：

  
  
  

   
   
   
org.apache.ibatis.binding.BindingException:
   
   
   

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

实际情况：

sql删除没有返回值：

   
   
   

    
    
    
<!--根据选择删除-->
    
    
    
 <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中却有返回值，这里出错了

   
   
   

    
    
    
Integer[] toDeleteSelection(Integer[] arr);
   
   
   

应该改为：

   
   
   

    
    
    
void toDeleteSelection(Integer[] arr);
