Java Spring Mvc在提交后获取HTTP状态[404]–[Not Found]

我使用Spring Mvc，让控制器返回index.jsp页面

这是index.jsp页面

在index.jsp中处理提交操作的代码

我希望在提交弹出窗口后，我应该重定向到原始index.jsp页面

相反，我得到了以下错误：

HTTP Status [404] – [Not Found] after the submission

应用程序结构

dispatcher-servlet.xml文件中提供的JSP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>

如何解决这个问题？谢谢。

请尝试处理控制器的Post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，您可以获得模型映射上的参数：

<label>Amount</label> <span>${amount}</span>
<label>Adress</label> <span>${address}</span>

对于最佳实践，请不要在jsp文件中包含java代码

我不想进入URL localhost:8080/sendMoney.jsp。send money按钮应弹出提供的提交选项，发送后应进入原始页面。如何计算？您可以在Post请求映射上返回重定向，如下所示：return redirect:http://www.google.comI 把你的代码放在适当的位置。但是仍然不起作用。您可以共享新控制器以进行更多调查吗？我只需测试一个简单的控制器，它就可以工作重定向：@RequestMappingvalue={/}，method=RequestMethod.POST public String defaultPage{return redirect:http://www.google.com; }使用@RequestMapping/sendMoney将sendMoney.jsp代码移动到新控制器中，并重定向其中的主页。设置html form action=sendMoney以调用它。

<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>
