新手springmvc web简单搭建过程-caidachun

第一次做整了一天，中间各种报错，大佬肯定要嘲笑我了，但还是很有成就敢，现在只知道怎么装配，还不知道为什么，还需要学习、加油

1.新建动态web项目

2. 添加jar包，可以到网上下载，commons-logs.jar我是自己找的

3.web.xml配置，classpath:springmvc.xml,指定初始化参数springmvc加载文件，需要在src新建springmvc.xml

<?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"
    id="WebApp_ID" version="3.0">
<servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
 
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

4.配置springmvc.xml，建包com.springmvc.* 类必须建立在com.springmvc.*下。配置会扫描这个包 页面放在路径下/WEB-INF/pages/

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.0.xsd
       http://www.springframework.org/schema/util
       http://www.springframework.org/schema/util/spring-util-3.0.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
      ">
 
    <!-- 开启注解模式驱动 -->
    <mvc:annotation-driven></mvc:annotation-driven>
    <!-- 扫包 -->
    <context:component-scan
        base-package="com.springmvc.*"></context:component-scan>
    <!-- 静态资源过滤 -->
    <mvc:resources location="/resources/"
        mapping="/resources/**" />
 
    <!-- 视图渲染 jsp/freemaker/velocity -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 制定页面存放的路径 -->
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <!-- 文件的后缀 -->
        <property name="suffix" value=".jsp"></property>
    </bean>
