web.xml can't mark spring ServletDispatcher Properly

Question

So I'm making simple project for testing Spring Framework by this tutorial , and encounter a problem that I can't figure out.

My project structure:

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">

    <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>*.html</url-pattern>
        <url-pattern>*.htm</url-pattern>
        <url-pattern>*.json</url-pattern>
    </servlet-mapping>

</web-app>

dispatcher-servlet.xml:

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

    <context:component-scan base-package="com.itaSS.controller" />

</beans>

HomeController.java:

package com.itaSS.controller;

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

@Controller
public class HomeController {

    @RequestMapping("/home")
    public String home() {
        return "/WEB-INF/jsp/home.jsp";
    }
}

So when after deploying war on tomcat and trying go for localhost:8080/home.html I get this:

I'm sure that in web.xml is some mistake or I'm missed something. I'll be very grateful if someone helped me with this!

Answer 1

我认为您在dispatcher-servlet.xml文件中的行下方丢失了。

<mvc:annotation-driven/>

Answer 2

You need to define a ViewResolver in your application context file dispatcher-servlet.xml like this :

<bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
    <property name="prefix" value="/WEB-INF/jsp/"/>
    <property name="suffix" value=".jsp"/>
</bean>
