1.创建 web 工程
创建 web 工程.png
2.导入 jar 包

3.修改 web.xml 文件
<?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_2_5.xsd"
id="WebApp_ID" version="2.5">

<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>

</welcome-file-list>
<filter>
<filter-name>characterEncoding</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>
<!-- 拦截所有请求，对所有请求参数都必须进行编码 -->
<filter-mapping>
<filter-name>characterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- springmvc中央控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 加载springmvc配置文件 -->
<!-- 方式一： 加载默认配置文件：（满足规范） 名称规范：<servlet-name>-servlet.xml ===> springmvc-servlet.xml
路径规范：/WEB-INF/下面，才能被springmvc自动解析 -->
<!-- 方式二：加载自定义配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
4.创建一个 source folder 目录 （config）
创建一个 datasource 目录.png
5.创建 log4j 配置文件（log4j.properties）
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:/mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### set log levels - for more verbose logging change 'info' to 'debug' ###
log4j.rootLogger=debug, stdout
- 创建 springmvc.xml 文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop"

http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<!-- 扫描Controller -->
<context:component-scan base-package="com.xiaocai"></context:component-scan>
<!-- springmvc视图解析器：解析出真正物理视图 返回逻辑视图： -->
<!-- index 解析出真正物理视图:前缀+逻辑视图+后缀 ==> /WEB-INF/jsps/index.jsp -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/jsps/"></property>
<!-- 后缀 -->
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
- 编写 controller 代码 （HelloSpringController）
@Controller
public class HelloSpringController {
/**
* model是什么？
* model顶层是map，是一个Request域，model中值可以使用el表达式获取
*/
@RequestMapping("/hello/springmvc")
public String list(Model model){
//放入数据
model.addAttribute("hello", "hello springmvc!");
//返回逻辑视图
return "index";
}
}

8.创建 jsps 文件夹并编写相应的 jsp 文件
<%@ 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>Insert title here</title>
</head>
<body>
<h1>转发:${hello }</h1>
</body>
</html>
创建 jsps 文件夹并编写相应的 jsp 文件.png
- 查看URL前缀
查看URL前缀.png
- 运行 tomcat 并打开网页测试
http://localhost:8080/xiaocai_springmvc_01/hello/springmvc.do
打开网页测试.png
