Ciao a tutti, sto facendo i primi passi con il framework Spring ma sto avendo qualche problema a far funzionare il mio primo Hello World.
Dunque seguendo un tutorial trovato online ho creato sotto WEB-INF il file project-servlet.xml nel seguente modo:
e ho scritto il web.xml nel seguente modo:codice:<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation=" http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd" > <annotation-driven /> <context:component-scan base-package="it.telecomitalia.controller" /> <beans:bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <beans:property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> <beans:property name="prefix" value="/WEB-INF/jsp/" /> <beans:property name="suffix" value=".jsp" /> </beans:bean> </beans:beans>
La classe controller è così definita:codice:<?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_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>project</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>project</servlet-name> <url-pattern>/welcome.jsp</url-pattern> <url-pattern>/welcome.html</url-pattern> </servlet-mapping> </web-app>
e le jsp sono le seguenti:codice:package it.telecomitalia.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller @RequestMapping("/welcome") public class HelloWorldController { @RequestMapping(method = RequestMethod.GET) public ModelAndView helloWorld() { String message = "<br><div style='text-align:center;'>" + "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CrunchifyHelloWorld.java **********</div><br><br>"; return new ModelAndView("welcome", "message", message); } }
index.jsp
e welcome.jsp nella cartella WEB-INF/jspcodice HTML:<html><head><title>Spring MVC Test web app</title><style type="text/css"></style></head><body> <br> <div style="text-align:center"> <h2> Hey You..!! This is your 1st Spring MCV Tutorial..<br> <br> </h2> <h3> <a href="welcome.html">Click here to See Welcome Message... </a>(to check Spring MVC Controller... @RequestMapping("/welcome")) </h3> </div></body></html>
codice HTML:<%@ 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><title>Hello World Spring MVC Example</title><style type="text/css"></style></head><body> ${message}</body></html> ma se provo ad accedere a welcome.jsp mi da errore 404 resource not available Che sto sbagliando? Grazie a chi mi aiuterà
