SpringMVC_入门项目

    本项目是SpringMVC的入门项目，用于演示SpringMVC的项目配置、各层结构，功能较简单

一、Eclipse中创建maven项目

二、pom.xml添加依赖

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

<dependency>     <groupId>javax.servlet</groupId>     <artifactId>javax.servlet-api</artifactId>     <version>3.1.0</version> </dependency> <dependency>     <groupId>javax.servlet.jsp</groupId>     <artifactId>jsp-api</artifactId>     <version>2.2</version> </dependency>   <!--① 依赖的Spring模块类库 --> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-context</artifactId>     <version>3.1.1.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-beans</artifactId>     <version>3.1.1.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-web</artifactId>     <version>3.2.3.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>3.2.3.RELEASE</version> </dependency>

三、web.config配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">     <display-name>SpringMVC</display-name>           <!-- Spring应用上下文， 理解层次化的ApplicationContext -->     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>/WEB-INF/applicationContext.xml</param-value>     </context-param>     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>                 <!-- DispatcherServlet, Spring MVC的核心 -->     <servlet>         <servlet-name>mvc-dispatcher</servlet-name>         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>         <!-- DispatcherServlet对应的上下文配置， 默认为/WEB-INF/$servlet-name$-servlet.xml -->         <init-param>             <param-name>contextConfigLocation</param-name>             <param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>         </init-param>         <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>         <servlet-name>mvc-dispatcher</servlet-name>         <!-- mvc-dispatcher拦截所有的请求 -->         <url-pattern>/</url-pattern>     </servlet-mapping> </web-app>

四、添加applicationContext.xml配置文件 
        文件路径对应web.xml中<context-param><param-value>节点值

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"     xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx-3.1.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">           <!-- 扫描类包，将标注Spring注解的类自动转化Bean，同时完成Bean的注入 -->     <context:component-scan base-package="com.james"/> </beans>

五、添加mvc-dispatcher-servlet.xml配置文件

        文件路径对应web.xml中<servlet><init-param><param-value>节点值

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

<?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"     xmlns:mvc="http://www.springframework.org/schema/mvc"     xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd         http://www.springframework.org/schema/mvc         http://www.springframework.org/schema/mvc/spring-mvc.xsd">     <context:component-scan base-package="com.james">         <context:include-filter type="annotation"             expression="org.springframework.stereotype.Controller" />     </context:component-scan>       <!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 -->     <mvc:annotation-driven />       <!-- 静态资源处理， css， js， imgs -->     <mvc:resources mapping="/resources/**" location="/resources/" />       <!-- /WEB-INF/views/ 对应jsp文件路径 -->     <bean         class="org.springframework.web.servlet.view.InternalResourceViewResolver">         <property name="viewClass"             value="org.springframework.web.servlet.view.JstlView" />         <property name="prefix" value="/WEB-INF/views/" />         <property name="suffix" value=".jsp" />     </bean> </beans>

六、添加web、service、dao层及类

        1、HelloController.java  包自定义

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

package com.web.controller;   import javax.servlet.http.HttpSession; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.james.service.HelloService;   @Controller @RequestMapping("/hello") public class HelloController {       @Autowired     private HelloService service;           @RequestMapping("/mvc")     public String helloMvc(HttpSession httpSession) {           System.out.println("进入：HelloController-->helloMvc");         this.service.helloMvc();                   // 视图渲染，/WEB-INF/views/home.jsp         return "home";     } }

        2、HelloService.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

package com.service;   import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;   import com.dao.HelloDao;   @Service public class HelloService {           @Autowired     private HelloDao dao;           public void helloMvc() {         System.out.println("进入：HelloService-->helloMvc");                   this.dao.helloMvc();     } }

        3、HelloDao.java

1 2 3 4 5 6 7 8 9 10 11 12

package com.dao;   import org.springframework.stereotype.Repository;   @Repository public class HelloDao {     public void helloMvc() {         System.out.println("进入：HelloDao-->helloMvc");                   System.out.println("进入：HelloDao-->helloMvc2");     } }

七、利用jetty启动mvc并查看输出
