Question

我创建简单的Spring应用程序。我有两个视图（格式，确认），模型（用户）和Spring Bean-Controller（Main_Controller）。当我在地址http://localhost:8080/Path/forma.htm上并填写所有格式字段时提交格式玻璃鱼说HTTP状态400 - 错误请求。为什么？要正常工作，我应该看到一个包含客户端条目的确认页面。

Main_Controller

package kontroleri;    

@RequestMapping(value = "/forma",method = RequestMethod.GET)
public String pozivanjeForme(Model model)
{
    model.addAttribute("user",new User());
    return "forma";
}


@RequestMapping(value="/forma",method= RequestMethod.POST)
public String confirm(@ModelAttribute("user")User user,ModelMap model)
{
    model.addAttribute("first_name",user.getFirst_name());
    model.addAttribute("last_name",user.getLast_name());
    model.addAttribute("date_of_birth",user.getDate_of_birth());
    model.addAttribute("pid",user.getPid());
    model.addAttribute("email",user.getEmail());
    model.addAttribute("country",user.getCountry());
    model.addAttribute("city",user.getCity());
    model.addAttribute("postal",user.getPostal());

    return "confirmation";
}

}

用户

@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
private LocalDate date_of_birth;

    this.first_name = first_name;

    this.pid = pid;

调度-servlet.xml中

<?xml version='1.0' encoding='UTF-8' ?>

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="index.htm">indexController</prop>
            <prop key="forma.htm">Kontroler</prop>
        </props>
    </property>
</bean>
<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/"
      p:suffix=".jsp" />

<bean name="indexController"
      class="org.springframework.web.servlet.mvc.ParameterizableViewController"
      p:viewName="index" />

<bean class="kontroleri.Main_Controller" id="Kontroler"/>

Answer 1

请在dispatcher-servlet.xml中定义额外的命名空间

<beans
    ... 
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    ...
    xsi:schemaLocation="
    ...
    http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

添加<mvc:annotation-driven/>以启用注释驱动并支持格式化日期等字段。
