未从HTML表单调用弹簧控制器提交

我想在我的HTML表单的提交操作上调用一个简单的弹簧控制器。但是弹簧控制器没有被调用。我搜查allot，但没有理解缺失点。任何人都可以帮助解决这个问题。未从HTML表单调用弹簧控制器提交

下面是我的web.xml

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

</context-param>

</listener> 
<listener> 
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>

<servlet>

</servlet-mapping> 
<servlet-mapping> 
<servlet-name>Faces Servlet</servlet-name> 
<url-pattern>*.jsf</url-pattern> 
</servlet-mapping> 
</web-app>

和我为spring-servlet.xml如下所示。

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

<property name="userLogin" ref="userLogin"></property> 
<property name="loginBean" ref="loginBean"></property> 
</bean> 
</beans>

和我的JSP是如下：

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> 
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> 
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
%> 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<f:subview id="user_login_subview"> 
<html> 
<head> 
<base href="<%=basePath%>">

<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="description" content="This is my page"> 
<!-- 
<link rel="stylesheet" type="text/css" href="styles.css">

</head> 
<body> 
<form id="login_form" method="post" action="/processLogin"> 
<div id="login_div"> 
<h3 id="login_text" class="borderText">LOGIN</h3> 
<div id="user_name_div"> 
<h:outputText id="loging_label" value="Username :" /> 
<h:inputText id="login_field" size="30" value="#{loginBean.userName}" tabindex="1" styleClass="textBox"></h:inputText> 
</div> 
<div id="password_div"> 
<h:outputText id="password_label" value="Password :" /> 
<h:inputText id="password_field" size="30" value="#{loginBean.password}" tabindex="2" styleClass="textBox"></h:inputText> 
</div> 
<div id="remember_me_div"> 
<h:selectBooleanCheckbox id="remember_me_checkbox" value="#{loginBean.rememberMe}" tabindex="3" styleClass="checkbox"/> 
<h:outputText id="remember_me_label" value="Remember me" /> 
</div> 
<div id="action_buttons_div"> 
<input type="submit" id="submit_button" value="submit" class="button"/> 
<input type="reset" id="reset_button" value="reset" class="button"/> 
</div> 
</div> 
</form> 
</body> 
</html> 
</f:subview>

和控制器UserLogin.java是如下，

package com.src.main; 
public class UserLogin { 

private String userName; 
private String password; 

public UserLogin(){ 

} 
public String getUserName() { 
return userName; 
} 
public void setUserName(String userName) { 
this.userName = userName; 
} 
public String getPassword() { 
return password; 
} 

public void setPassword(String password) { 
this.password = password; 
} 


}

我的控制器的名字是：

package com.src.main.process; 

import org.springframework.stereotype.Controller; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 

import com.src.main.LoginBean; 
import com.src.main.UserLogin; 
@Controller 
public class HandleApplicationInitProcessor { 

private UserLogin userLogin; 
private LoginBean loginBean; 
public HandleApplicationInitProcessor() { 
} 

@RequestMapping(value = "/processLogin", method = RequestMethod.POST) 
public String process(){ 

this.getUserLogin().setUserName(this.getLoginBean().getUserName()); 
this.getUserLogin().setPassword(this.getLoginBean().getPassword()); 
System.err.println("UserName : "+this.getUserLogin().getUserName()); 
System.err.println("Password : "+this.getUserLogin().getPassword()); 


return "Hello World !"; 
} 
public UserLogin getUserLogin() { 
return userLogin; 
} 
public void setUserLogin(UserLogin userLogin) { 
this.userLogin = userLogin; 
} 
public LoginBean getLoginBean() { 
return loginBean; 
} 

public void setLoginBean(LoginBean loginBean) { 
this.loginBean = loginBean; 
} 
}

最初我正在尝试使用JSF表单提交标签，但由于这个问题，我尝试了简单的HTML表单提交，但仍然是同样的问题。我的控制台上也没有出现任何错误。

您正混杂着JSF和Spring Web MVC代码。您还没有在web.xml中声明DispatcherServlet。请通过Spring Web MVC入门教程。 – shazin 2015-01-04 14:58:43

我不想使用它。这就是为什么我添加了requestcontextListener。 – 2015-01-04 15:03:01

我认为你应该做如下修改代码中的

1.Declare 的DispatcherServlet在web.xml文件，如下图所示。例如： -

 <servlet> 
     <servlet-name>mvc-dispatcher</servlet-name> 
      <servlet-class> 
         org.springframework.web.servlet.DispatcherServlet 
      </servlet-class> 
      <load-on-startup>1</load-on-startup> 
     </servlet> 

     <servlet-mapping> 
     <servlet-name>mvc-dispatcher</servlet-name> 
      <url-pattern>*.htm</url-pattern> 
     </servlet-mapping>

2.从弹簧配置文件中删除下面的行。

<bean id="handleApplicationInitProcessor" class="com.src.main.process.HandleApplicationInitProcessor"> 
    <property name="userLogin" ref="userLogin"></property> 
    <property name="loginBean" ref="loginBean"></property> 
</bean>

3.Just地方@Autowired你在哪里声明它（Controller class）之前。像下面

@Autowired 
private UserLogin userLogin; 
@Autowired 
private LoginBean loginBean;

4.取出<context:annotation-config/>与您使用<mvc:annotation-driven />。

如果我使用此标记并执行上述更改，我的控制器会被调用。

？ – RE350 2015-01-04 15:30:02

在下面的控制器中更改您的方法，传递参数@RequestBody UserLogin userLogin，其中包含您从JSP页面发送的值.. – RE350 2015-01-04 15:32:32
