我使用 Spring Mvc 并让 Controller 返回 index.jsp 页面，
@Controller
public class BitcoinWalletController {
@RequestMapping("/")
public String showBitcoinWallet() {
return "index";
}
}
这是index.jsp页面，
处理提交操作的代码(在index.jsp内)，
<form id="send-form" class="form-horizontal" action="sendMoney.jsp" method="POST">
<div class="modal-body">
<div class="form-group">
<label for="amount" class="col-sm-2 control-label">Send</label>
<div class="col-xs-4">
<input id="amount" name="amount" class="form-control" value="0">
</div>
<div class="btc-col">
<span>BTC</span>
</div>
</div>
<div class="form-group">
<label for="address" class="col-sm-2 control-label">to</label>
<div class="col-sm-10">
<input id="address" name="address" class="form-control">
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-default">Send</button>
</div>
</form>
提供的 sendMoney.jsp 代码，
<%@ page import="com.puut.bitcoin.WalletSendMoneyController" %>
<html>
<body>
<%
String amount = request.getParameter("amount").trim();
String address = request.getParameter("address").trim();
WalletSendMoneyController.getSendMoneyController().send(address, amount);
// New location to be redirected
String site = new String("/");
response.setStatus(response.SC_MOVED_TEMPORARILY);
response.setHeader("Location", site);
%>
</body>
</html>
我希望在提交弹出窗口后，我应该重定向到原始的 index.jsp 页面。
相反，我收到以下错误，
HTTP Status [404] – [Not Found] after the submission
应用程序结构，
dispatcher-servlet.xml 文件中提供的 jsps 位置，
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsps/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
web.xml 知道dispatcher-servlet.xml 的位置，
<servlet>
<description></description>
<display-name>dispatcher</display-name>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
除了@RequestMapping("/")之外，我没有其他映射。
如果我从 index.jsp 中删除 action="sendMoney.jsp" 并按照建议使用具有 POST 方法的另一个 Controller ，我收到以下错误堆栈，
Type Exception Report
Message Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.http.MediaType.compareTo(Lorg/springframework/http/MediaType;)I

如何解决这个问题？谢谢。
最佳答案
请尝试处理来自 Controller 的发布请求
@RequestMapping(value="/", method=RequestMethod.POST)
public ModelAndView PostBitcoinWallet(@RequestParam String amount,@RequestParam String address) {
ModelMap modelMap = new ModelMap();
modelMap.put("amount", amount);
modelMap.put("address", address);
return new ModelAndView("sendMoney",modelMap);
}
在 sendMoney.jsp 上，您可以获得放在 modelMap 上的参数:
<label>Amount</label> <span>${amount}</span>
<label>Adress</label> <span>${address}</span>
最佳实践是不要在 jsp 文件中包含 java 代码
