springmvc基本配置

1.开发环境搭建，我用的是eclipse+tomcat7+jdk1.6，这部分不做介绍

2.新建工程，我新建的是dynamic web project 命名为springmvc1

3.导入jar包，我用的是springframework3.1.1，目前官网spring不能下载，我是下载的源文件，用ant编译的。需要导入的jar包有：

4.编写WEB-INF/web.xml如下：

<?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">
    <display-name></display-name>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- springMVC 配置 -->
    <servlet>
        <description>spring mvc servlet</description>
        <servlet-name>springMvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <description>spring mvc 配置文件</description>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-mvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 拦截以html为后缀的请求 -->
    <servlet-mapping>
        <servlet-name>springMvc</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>10</session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>/views/index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

5.编写spring-mvc.xml以及spring.xml文件

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-3.0.xsd 
http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
    <context:annotation-config />
    <context:component-scan base-package="com.rainbow.controller" />

    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">

    </bean>

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

spring.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-3.0.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.0.xsd
    ">

    <!-- 引入属性文件 -->
    <context:property-placeholder location="classpath:database.properties" />

    <!-- 自动扫描controller,dao,service包(自动注入) -->
    <context:annotation-config />
    <context:component-scan base-package="com.rainbow" />
    

</beans>

6.编写controller文件，在src目录下建立package

package com.rainbow.controller;

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

@Controller
public class TestController {

    @RequestMapping("/hello")
    public String hello(){
        return "/hello";
    }
}

以上是简单的java文件，

7.编写视图文件，hello.jsp

<%@ 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>
Hello world!
</body>
</html>

8.run 项目， 我们输入http://localhost:9090/springmvc1/hello.do便可以获得hello world的页面输出，以上是spring最基本的配置。 目前并没有显示数据层的东西。

主要是给自己做一下记录，防止忘记。

下一篇介绍，导入数据库，以及hibernate。
