Question

我尝试在hello.jsp文件中打印邮件。我包含了必要的jstl库文件，但它打印的是${message}而不是Welcome to the hello page。controller和hello.jsp的代码如下： -

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


/**
 * Created by CAN14 on 6/14/2016.
 */
@Controller
public class HelloController{

    @RequestMapping(value="/hello", method= RequestMethod.GET)
    public ModelAndView handleRequest() throws Exception{
        ModelAndView model= new ModelAndView("hello");
        model.addObject("message","Welcome to the hello page");

        return model;
    }

}

的hello.jsp

<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<c:out value="${messsage}" />

web.xml文件如下： -

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>helloworld</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>helloworld</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

helloworld-servlet.xml如下： -

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.abhishek" annotation-config="true"/>

    <!--<bean name="/hello.ds" class="com.abhishek.HelloController" />-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" >

        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>

    </bean>
</beans>
