springmvc入门程序总结

1.创建WEB 工程，引入开发的jar包

具体坐标如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  91.       </plugins>
  92.     </pluginManagement>
  93.   </build>
  94. </project>

2.配置核心控制器（配置DispatcherServlet）

在 web.xml 配置文件中配置 核心控制器 DispatcherServlet

  1. <!DOCTYPE web-app PUBLIC
  2.  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
  3.  "http://java.sun.com/dtd/web-app_2_3.dtd" >
  5. <web-app>
  6.   <display-name>Archetype Created Web Application</display-name>
  8.   <!--配置前端控制器-->
  9.   <servlet>
  10.     <servlet-name>dispatcherServlet</servlet-name>
  11.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  12.     <init-param>
  13.       <param-name>contextConfigLocation</param-name>
  14.       <param-value>classpath:springmvc.xml</param-value>
  15.     </init-param>
  16.     <load-on-startup>1</load-on-startup>
  17.   </servlet>
  18.   <servlet-mapping>
  19.     <servlet-name>dispatcherServlet</servlet-name>
  20.     <url-pattern>/</url-pattern>
  21.   </servlet-mapping>
  23.   <!--配置解决中文乱码的过滤器-->
  24.   <filter>
  25.     <filter-name>characterEncodingFilter</filter-name>
  26.     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  27.     <init-param>
  28.       <param-name>encoding</param-name>
  29.       <param-value>UTF-8</param-value>
  30.     </init-param>
  31.   </filter>
  32.   <filter-mapping>
  33.     <filter-name>characterEncodingFilter</filter-name>
  34.     <url-pattern>/*</url-pattern>
  35.   </filter-mapping>
  37. </web-app>

3.编写 SpringMVC.xml的配置文件

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:mvc="http://www.springframework.org/schema/mvc"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  6.        xsi:schemaLocation="
  7.         http://www.springframework.org/schema/beans
  8.         http://www.springframework.org/schema/beans/spring-beans.xsd
  9.         http://www.springframework.org/schema/mvc
  10.         http://www.springframework.org/schema/mvc/spring-mvc.xsd
  11.         http://www.springframework.org/schema/context
  12.         http://www.springframework.org/schema/context/spring-context.xsd">
  14.     <!-- 开启注解扫描 -->
  15.     <context:component-scan base-package="cn.itcast"/>
  17.     <!-- 视图解析器对象 -->
  18.     <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  19.         <property name="prefix" value="/WEB-INF/pages/"/>
  20.         <property name="suffix" value=".jsp"/>
  21.     </bean>
  23.     <!--配置自定义类型转换器-->
  24.     <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
  25.         <property name="converters">
  26.             <set>
  27.                 <bean class="cn.itcast.utils.StringToDateConverter"/>
  28.             </set>
  29.         </property>
  30.     </bean>
  33.     <!-- 开启SpringMVC框架注解的支持 -->
  34.     <mvc:annotation-driven conversion-service="conversionService"/>
  36. </beans>

4.编写 index.jsp 和 HelloController 控制器类

index.jsp 

  1. <body>
  2.     <h3>入门案例</h3> 
  3.         <a href="${pageContext.request.contextPath}/hello">入门案例</a>  
  4. </body>

HelloController

  1. package cn.itcast.controller;
  3. import org.springframework.stereotype.Controller;
  4. import org.springframework.web.bind.annotation.RequestMapping;
  6. // 控制器类
  7. @Controller
  8. @RequestMapping(path="/user")
  9. public class HelloController {
  11.     /**
  12.      * 入门案例
  13.      * @return
  14.      */
  15.     @RequestMapping(path="/hello")
  16.     public String sayHello(){
  17.         System.out.println("Hello StringMVC");
  18.         return "success";
  19.     }
  20. }

5.在 WEB-INF目录下创建 pages 文件夹，编写 success.jsp 的成功页面。

  1. <body>
  3.     <h3>入门成功</h3>
  5. </body>

6.启动 Tomcat 服务器，进行测试。
