使用patch方式，使用@RequestParam注入参数，会获取不到参数，
查阅后发现http请求使用patch，后台Springmvc处理请求参数问题分析较具体

业务代码：

@RequestMapping(value = "/phone", method = RequestMethod.PATCH)
    public RestStatus phone(@RequestParam String number, @LoggedInUser Employee loggedInEmployee) {
        if (StringUtil.isBlank(number)) {
            throw RestStatus.valueOf(RestStatus.CODE_FIELD_INVALID, "请提供待修改手机号");
        }
        if (!BusiUtil.validateMobileNo(number)) {
            throw RestStatus.valueOf(RestStatus.CODE_FIELD_INVALID, "待修改手机号格式错误");
        }

        loggedInEmployee.setPhone(number);
        employeeManager.save(loggedInEmployee);
        return RestStatus.OK;
    }
