基于Java代码实现支付充值的通用流程
废话不多说了，直接给大家贴java代码了。
具体代码如下所示：
/*支付流程*/
/****Controller.java 代码如下：*/
@RequestMapping(value = \"/paySubmit.htm\", method = RequestMethod.POST)
public ModelAndView paySubmit(HttpServletRequest request,
HttpServletResponse response, @RequestParam Map<String, Object> maps){
ModelAndView model = new ModelAndView(\"***/submit\");
/**
* 代码块
*/
return model;
}
/*submit.jsp 代码如下：*/
