jsp中from表单input输入值传递到后台的问题

SSM

class="cursor-pointer"> 详细描述

获取的传值为String “{nowpage}”，而不是期待的input输入的内容 “5”。

没有报错，只是报的[WARN]。
后台无反应。
*@PathVariable("nowpage")int nowpage从url路径里（@RequestMapping(value = "/pages/{nowpage}/{pagesize}",method = RequestMethod.POST)）获取值的问题。
如果有师兄知道可能的错误请指教一下。（可能是配置的问题或者说是传递方式的问题，或者使用方法有问题）
1.在使用@PathVariable("nowpage")int nowpage的情况下，jsp需要用什么方式获取到input输入的值然后写入action或者url里（不使用js）。使“/page/{nowpage}”访问的时候变成“/page/5”（5是input输入的参数）
2.后台会提示下面警告：
[WARN]-[org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver] Failed to bind request element: org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "{nowpage}"
错误代码
jsp：
HTTP Status 400 – Bad Request
error：
Failed to convert value of type 'java.lang.String' to required type 'int'; nested exception is java.lang.NumberFormatException: For input string: "{nowpage}"

这里是字符串"{nowpage}" 用String接收也是"{nowpage}"，而不是期待的字符串类型 “5”
