• SpringMVC配置入門


    我的開發環境
      開發工具:    springsource-tool-suite-2.9.0
      JDK版本:    1.6.0_29
      tomcat版本:apache-tomcat-7.0.26

    go!

    step1.在你的開發環境新建一個工程,引入jar包

    Maven代碼:

    <!-- Spring MVC -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>3.2.4.RELEASE</version>
    </dependency>
    <!-- JSP -->
    <dependency>    
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>jstl-api</artifactId>
        <version>1.2</version>
    </dependency>

     step2:編輯web.xml

    <!DOCTYPE web-app PUBLIC
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
     "http://java.sun.com/dtd/web-app_2_3.dtd" >
    <web-app>
        <display-name>Archetype Created Web Application</display-name>
        <!-- 配置SpringMVC前端Servlet控制器DispatcherServlet -->
        <servlet>
            <servlet-name>dispatcherServlet</servlet-name>
            <servlet-class>
                org.springframework.web.servlet.DispatcherServlet
            </servlet-class>
            <!-- 配置初始的DispatcherServlet上下文配置文件加載路徑 -->
            <init-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>
                    classpath:conf/spring/spring-servlet.xml
                </param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <!-- 讓DispatcherServlet處理所有以".htm"結尾的URL -->
        <servlet-mapping>
            <servlet-name>dispatcherServlet</servlet-name>
            <url-pattern>*.htm</url-pattern>
        </servlet-mapping>
        <!-- 配置DispatcherServlet上下文配置文件加載路徑 -->
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:conf/spring/spring-servlet.xml
            </param-value>
        </context-param>
        <!-- 配置上下文載入器 -->
        <listener>
            <listener-class>
                org.springframework.web.context.ContextLoaderListener
            </listener-class>
        </listener>
    </web-app>

    step3.編輯DispatcherServlet上下文配置文件

        在step2中,我們配置了DispatcherServlet上下文配置文件的路徑為conf/spring/spring-servlet.xml,所以在src/main/resources/conf/spring目錄下新建spring-servlet.xml文件,代碼如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <!-- 配置SpringMVC配置文件所需的xml文件解析模板 -->
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://cxf.apache.org/core"
        xmlns:tx="http://www.springframework.org/schema/tx" 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://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd 
           http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
        <!-- 配置控制器要掃描的包路徑 -->
        <context:component-scan base-package="www.asuan.com" />
        <!-- 配置視圖解析器 -->
        <bean id="jspViewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
            <!-- 解析器解析/WEB-INF/jsp/路徑下,以.jsp結尾的視圖文件 -->
            <property name="prefix" value="/WEB-INF/jsp/" />
             <property name="suffix" value=".jsp" />
        </bean>    
    </beans>

    step4.編寫controller和jsp文件

      在step3中,我們配置了包掃描路徑為"www.asuan.com",所以在src/main/java目錄下新建包www.asuan.com.controller,在包內新建HelloWorldController.java,代碼如下:

    package www.asuan.com.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class HelloWorldController {
        @RequestMapping("/helloWorld")//url字段名
        public String helloWorld() {
            return "helloWorld";//jsp文件名
        }
    }

        視圖解析路徑設置為WEB-INF/jsp,所以在WEB-INF/jsp目錄下新建helloWorld.jsp文件(文件名為controller方法中返回的字符串),代碼如下:

    <!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>
    <h2>Hello World!</h2>
    </body>
    </html>

    step5.運行與調試
    將工程部署到tomcat并運行,在瀏覽器輸入:http://localhost:8080/你設置的工程名/helloWorld.htm

    運行結果:

    complete!
