SpringMVC之学习（1）

先来一个springmvc的基本配置，照样输出hello world

1.先导入springmvc所需要的开发包

最起码需要这么多的基本包，然后开始上配置

2.先在web.xml里进行引入，和Struts的差不多，

<?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"

xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

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>SpringMvc</display-name>

  <!--配置DispatcherServlet-->

    <servlet>

        <servlet-name>spring</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <!--配置初始化参数：作用是配置SpringMVC配置文件的位置和名称-->

        <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>/WEB-INF/servlet.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>spring</servlet-name>

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

    </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <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>

</web-app>

　3.然后就是写springmvc本身的配置文件了，名为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:tx="http://www.springframework.org/schema/tx"

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

    xmlns:mvc="http://www.springframework.org/schema/mvc"

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

    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

    http://www.springframework.org/schema/tx

    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd

    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/context/spring-context-3.2.xsd

    http://www.springframework.org/schema/mvc

    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <!--配置自动扫描的包-->

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

    <!--配置视图解析器:如何把handle方法返回值解析为实际的物理视图-->

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

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

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

    </bean>

</beans>

　可以看出springmvc的配置文件真的很少。

4.开始写action了 Helloworld.java

package com.sun.action;

import org.springframework.stereotype.Controller;

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

@Controller

public class Helloworld {

	@RequestMapping("/hello")

	public String hello(){

		System.out.println("hello world");

		return "success";

	}

	@RequestMapping("/login")

	public String say(){

		System.out.println("login");

		return "login";

	}

}

　5.随便定义一个jsp文件，名为：success.jsp　

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

    pageEncoding="UTF-8"%>

<!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=UTF-8">

<title>Hello World</title>

</head>

<body>

<B>Hello World</B>

</body>

</html>

　在Struts里面，通过在xml里配置，通过返回值来选择返回的页面，而springmvc是直接返回值和文件名同名就行

6.这样基本，就能够访问了。

http://localhost:8080/SpringMvc/hello
