问题描述
我使用Spring Mvc并让控制器返回index.jsp页面
I work with Spring Mvc and have the controller returns the index.jsp page,
@Controller
public class BitcoinWalletController {
@RequestMapping("/")
public String showBitcoinWallet() {
return "index";
}
}
这是index.jsp页面，
用于处理提交操作的代码(在index.jsp内部)
The code to handle the submission operation (inside the index.jsp),
<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的代码
<%@ 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之后，我应该重定向到原始的index.jsp页面.
I expect that after the submission of the pop-up, I should redirected to the original index.jsp page.
相反，出现以下错误
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，
The jsps location provided in the dispatcher-servlet.xml file,
<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，
The web.xml knows where the dispatcher-servlet.xml is located,
<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("/")，我没有其他mapping.
如果我从index.jsp中删除了action="sendMoney.jsp"，并按照建议使用了另一个使用POST方法的控制器，则会收到以下错误堆栈，
If I remove the action="sendMoney.jsp" from the index.jsp and have another controller with the POST method as suggested, I get the following stack of errors,
Type Exception Report
Message Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.http.MediaType.compareTo(Lorg/springframework/http/MediaType;)I

如何解决此问题?谢谢.

推荐答案
请尝试处理来自控制器的发帖请求
Please to try handle the Post Request from controller
@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);
}
并在sendMoney.jsp上，您可以获取放置在modelMap上的参数:
and on sendMoney.jsp you can get the parametres puted on the modelMap :
<label>Amount</label> <span>${amount}</span>
<label>Adress</label> <span>${address}</span>
为获得最佳实践，请不要在jsp文件中包含Java代码
For best practices do not include java code on jsp file
