spring jar包下载： http://www.springsource.org/download/community
freemarker jar包下载：http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.freemarker&version=2.3.18
1、创建一个web项目：springmvc
2、将spring 3.0 中的jar包全部拷贝到项目中来
3、将freemaker的包也拷贝到项目中来，注意导入commons-logging.jar
4、配置web.xml :
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- Spring 服务层的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Spring 容器启动监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!--为DispatcherServlet建立映射 --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
5、在WEB-INF/目录下创建springmvc-servlet.xml文件， 注意springmvc-servlet名称是根据web.xml里配置的servlet名称+servlet.xml来的
6、配置springmvc-servlet.xml文件：
<?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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <!--以下视图配置根据需要任选一种即可 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="suffix"> <value>.ftl</value> </property> <property name="viewClass"> <value>org.springframework.web.servlet.view.freemarker.FreeMarkerView </value> </property> </bean> <bean name="HelloAction" class="myspring.mvc.web.SpringMvcController" /> <!-- 配置 控制器 --> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="/hello">HelloAction </prop> <!-- 映射URL访问 --> </props> </property> </bean> <!-- 配置freemarker --> <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/view/" /> <property name="freemarkerSettings"> <props> <prop key="template_update_delay">0</prop> <prop key="default_encoding">UTF-8</prop> <prop key="number_format">0.##########</prop> <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop> <prop key="classic_compatible">true</prop> <prop key="template_exception_handler">ignore</prop> </props> </property> </bean> </beans>
7、在WEB-INF/目录下创建view/ftl/welcome.ftl .
welcome.ftl 模板文件的内容如下 ：
<!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=ISO-8859-1"> <title>Insert title here</title> </head> <body> info : ${name} </body> </html>
8、编写控制器：
package myspring.mvc.web; import java.lang.annotation.Annotation; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; public class SpringMvcController implements Controller{ public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception { // request.setAttribute("name", "welcome to spring!"); // return new ModelAndView("ftl/welcome"); ModelAndView mv = new ModelAndView("ftl/welcome");// //welcome就是视图的名称welcome.ftl mv.addObject("name"," Hello world , test my first spring mvc ! "); return mv; } }
9、此时src目录下的applicationContext.xml暂且不需配置
运行项目，输入:http://localhost:8080/springmvc/hello
页面会输出： info : Hello world , test my first spring mvc !
项目结构如下：
