基于Java代码实现支付充值的通用流程

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 maps){

ModelAndView model = new ModelAndView("***/submit");

/**

* 代码块

*/

return model;

}

/*submit.jsp 代码如下：*/

<%@ page contentType="text/html;charset=UTF-8" language="java" trimDirectiveWhitespaces="true" %>

<%@ page import="com.***.util.PayUtil" %>

<%

request.setCharacterEncoding("UTF-8");

String type = (String) request.getAttribute("type");

String sHtmlText = "";

if ("1".equals(type)){

sHtmlText = PayUtil.buildForm(

(String) request.getAttribute("orderNo"),

(String) request.getAttribute("amt"),type);

}else{

sHtmlText = PayUtil.allInPaybuildForm(

(String) request.getAttribute("orderNo"),

(String) request.getAttribute("amt"),type,request);

}

out.println(sHtmlText);

%>

/* PayUtil.java 代码如下：*/

ArrayList keys = new ArrayList(sPara.keySet());

StringBuffer sbHtml = new StringBuffer();

sbHtml.append("

for(int i = 0; i < keys.size(); ++i) {

String name = (String)keys.get(i);

String value = (String)sPara.get(name);

sbHtml.append("");

}

sbHtml.append("

sbHtml.append("");

return sbHtml.toString();

}
