javaweb spring mvc intellj

1）New Project->Spring->Spring MVC, project name 为SpringHello

2) 在src文件加下创建package：cn.lgs.hello

3）在hello文件夹下创建类：HelloController

代码：

package cn.lgs.hello; 

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

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

import org.springframework.web.bind.annotation.RequestMethod;

 

/**

 * Created by Administrator on 2017/6/3.

 */

@Controller

@RequestMapping(value = "/hello", method = RequestMethod.GET)

public class HelloController {

    @RequestMapping(value = "/hello", method = RequestMethod.GET)

    public String printHello(ModelMap model) {

        model.addAttribute("msg", "Spring MVC Hello World!");

        model.addAttribute("name", "lgs");

        return "hello";

    }

}

4) 在WEB-INF下创建jsp文件夹，在文件夹下创建hello.jsp，并删除WEB-INF下自动创建的index.jsp

hello.jsp代码：

<%--

  Created by IntelliJ IDEA.

  User: Administrator

  Date: 2017/6/3

  Time: 18:06

  To change this template use File | Settings | File Templates.

--%>

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>${msg}</title>

</head>

<body>

<h1>${msg}</h1>

<span>${name}</span>

</body>

</html>

5）dispatcher-servlet.xml增加如下配置：

<context:component-scan base-package="cn.lgs.hello"/>

 

    <!-- 静态资源(js、image等)的访问 -->

    <mvc:default-servlet-handler/>

 

    <!-- 开启注解 -->

    <mvc:annotation-driven/>

 

    <!--ViewResolver 视图解析器-->

    <!--用于支持Servlet、JSP视图解析-->

    <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

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

        <property name="suffix" value=".jsp"/>

    </bean>

6）web.xml对应项作如下修改

  <url-pattern>/</url-pattern>

7) 主菜单Run->Edit Configrations，点击左上角"+"号，选择tomcat server->Local

server标签：name: tomcat8

Configure->Tomcat Home:C:\apache-tomcat-8

open browser: 第一个栏填：http://localhost:8080/hello/hello

deployment：点击“+”，添加artificat:SpringHelloTest:war exploded

9) 此时基本完毕，运行会提示错误：

org.apache.catalina.core.StandardContext.startInternal One or more listeners failed to start. Full details will be found in the appropriate container log file
