mybatis批量删除时传递参数的问题

//首先我们以传递的参数是数组为例
//批量删除
    @Test
    public void deleteuser(){
        SqlSession session=sessionFactory.openSession();
        UserMapper userMapper=session.getMapper(UserMapper.class);
        int num=0;
        int[] arr=new int[]{10,11};
        try {
            num = userMapper.deleteUser(arr);
            session.commit();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if (num<=0) {
            System.out.println("删除失败");
        }else {
            System.out.println("删除成功");
        }
