mybatis-mysql操作存储过程

java代码：

    @RequestMapping(value = "/testProcedure", method = RequestMethod.GET)
    public @ResponseBody String testProcedure(HttpServletRequest request, HttpServletResponse response) throws IOException {
        Map<String, Object> paraMap = new HashMap<String, Object>();
        //输出参数可以不传
        //paraMap.put("out_ret", -1);
        //paraMap.put("out_desc", "");
        //paraMap.put("userId", null);
        paraMap.put("user_pwd", "123456");
        paraMap.put("nickname", UUID.randomUUID().toString().replace("-", "").substring(0, 10));
        procedureMapper.testProcedure(paraMap);
        System.out.println(paraMap);
        return null;
    }

dao方法：

Map<String, Object> testProcedure(Map<String, Object> paraMap);
