我是春天的新人，我正在关注这个创建项目教程tutorial link

但是我的jsp并不知道传递的数据。

这是我的hello.jsp

＆＃13;

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body> 
      votre message est : ${message}
</body>
</html>

＆＃13;

和我的helloController.java

package web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class helloController {
@RequestMapping("/hello")
public ModelAndView helloWorld(){
  String message="Bonjour";
  return new ModelAndView("hello","message",message);
   }    
 }

和我的web.xml

＆＃13;

    <?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"

    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <servlet>
     <servlet-name>dispatcher</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
     <servlet-name>dispatcher</servlet-name>
     <url-pattern>*.htm</url-pattern>
  </servlet-mapping>
</web-app>

＆＃13;

和我的dispatcher-servlet.xml

＆＃13;

<?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"
	xmlns:p="http://www.springframework.org/schema/p"
	xmlns:jee="http://www.springframework.org/schema/jee"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/jee 
    http://www.springframework.org/schema/jee/spring-jee-4.0.xsd">
    <context:component-scan base-package="web"/>
    <bean id="viewResolver"  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix"><value>/jsp/</value></property>
          <property name="suffix"><value>.jsp</value></property>      
    </bean>
</beans>

＆＃13;

这是我的项目目录和hello.jsp运行结果：

Project directory + run result

Answer 1

实际上，您使用此网址直接访问您的jsp页面：localhost:8080/projetSpring/jsp/hello.jsp

您无法通过控制器进行操作，您需要使用以下网址：localhost:8080/projetSpring/hello.htm来调用DispatcherServlet并通过控制器进行传递

Spring数据传递
