一、项目的创建

1、创建webapp项目

2、pom文件的配置

  1. <dependency>
  2.   <groupId>javax.servlet</groupId>
  3.         <artifactId>javax.servlet-api</artifactId><!--全套关于Servlet的依赖-->
  4.     <version>3.1.0</version>
  5.   <scope>provided</scope>
  6. </dependency>
  7. <dependency>
  8.   <groupId>org.springframework</groupId>
  9.     <artifactId>spring-webmvc</artifactId><!--添加SpringMVC的依赖-->
  10.   <version>5.2.5.RELEASE</version>
  11. </dependency

３、相关注解

  1. //创建一个普通类
  2. @Controller        //控制器注释
  3. @RequestMapping("/common")//模块名称（类公共地址）
  4. class MyController{
  5.     //value={"/doSom.do","",""}，自定义接收的请求地址类型
  6.     //method = RequestMethod.POST，POST,GET等为枚举类型，这里是自定义接收请求的方式
  7.     @RequestMapping(value={"/doSom.do","",""},method = RequestMethod.POST)
  8.     public ModelAndView doSome(){
  9.         ModeAndView mv = new ModelAndView();
  10.         //用请求作用域对象添加KEY和VALUE
  11.         mv.addObject("key","StringValues");
  12.         ......
  13.         //请求转发
  14.         mv.setViewName("show");
  15.     }
  16. }

4、web.xml文件配置

  1. Servvlet配置
  2. <servlet>
  3.   <servlet-name>disPatcherServlet(自定义或不自定义类名)</servlet-name>
  4.   <servlet-class>org.springframework.web.servlet.DisPatcherServlet</servlet-class>
  5.   <init-param>
  6.       <param-name>contextConfigLocaltion</param-name>
  7.     <param-value>classpath:applicationContext.xml</param-value>
  8.   </init-param>
  9.   <load-on-start>1</load-on-start>
  10. </servlet>
  11. <servlet-mapping>
  12.   <servlet-name>disPatcherServlet</servlet-name>
  13.   <url-pattern>*.do</url-pattern>
  14. </servlet-mapping>
  16. 字符过滤器设置
  18. <filter>
  19.     <filter-name>CharacterEncodingFilter</filter-name>
  20.   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  21.           <!--
  22.                         框架源码参数
  23.             private String encoding;
  24.             private boolean forceRequestEncoding;
  25.             private boolean forceResponseEncoding;
  26.             -->
  27.   指定字符集
  28.   <init-param>
  29.     <init-name>encoding</init-name>
  30.       <param-value>utf-8</param-value>
  31.   </init-param>
  32.   强制设置请求编码
  33.   <init-param>
  34.     <param-name>forceRequestEncoding</param-name>
  35.       <param-value>true</param-value>
  36.   </init-param>
  37.   强行设置响应编码
  38.   <init-param>
  39.     <param-name>forceResponseEncoding</param-name>
  40.       <param-value>true</param-value>
  41.   </init-param>
  42. </filter>
  43. <filter-mapping>
  44.   <filter-name>characterEncodingFilter</filter-name>
  45.   <url-pattern>/*</url-pattern>
  46. </filter-mapping>

5、applicationContext.xml配置

  1. 组件扫描器
  2. <context:component-scanner base-package="com.bjpowernode.controller"/>
  4. 配置转发地址（ mv.setViewName("show");）
  5. <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  6.   <property name="prefix" value="/WEB-INF/view/"/>
  7.   <property name="suffix" value=".jsp"/>
  8. </bean>

6、jsp文件

  1. index.jsp
  2. <a href="doSome.do">点击这个</a>
  3. <a href="other.do">这是Other</a>
  4. ......
  6. show.jsp
  7. <center>
  8.     <h4>${msg}</h4>
  9.     <h4>${msgShow}</h4>
  10. </center>
  12. showOther.jsp
  13. <center>
  14.     <h1>this is other</h1>
  15.     <h4>${msg}</h4>
  16.     <h4>${msgShow}</h4>
  17. </center>

7、目录结构
