Question

我正在尝试从表单中保存数据但是正在获取＆＃34;客户端发送的请求在语法上是不正确的。 HTTP状态400＆＃34;。代码如下的的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  </servlet>
  <servlet-mapping>
    <servlet-name>sample</servlet-name>
    <url-pattern>/fila/*</url-pattern>
  </servlet-mapping>
</web-app>

样品servlet.xml中

Answer 1

在此方法中，您的要求客户提交volunteer

    @RequestMapping(value="/savReg", method=RequestMethod.POST)
    public String saveVol(@ModelAttribute("volunteer")Volunteer vol,ModelMap map){
        int id=service.saveVolunteer(vol);
        map.addAttribute("msg", "saved with id:"+id);
        return "volunteer";
    }

但是在你的jsp中，我看到你的表单没有volunteer。 <form action="savReg" method="post">您应该将modelAttribute = "volunteer"添加到form标记，以使您的表单提交对象类作为控制器中的要求。我们在here
