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);
