1.项目所需要jar包 (有些可能多余)
2.创建UserController 目录如下：
package qust.thb.usermanage.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; @Controller @RequestMapping("/user") public class UserController { @RequestMapping(value = "/getUser.do", method = RequestMethod.GET) public ModelAndView getUser() { ModelAndView mv = new ModelAndView(); mv.addObject("message", "nice to meet you!!!"); mv.setViewName("/view/hello"); return mv; } }
3.部署web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SpringMVC</display-name> <!-- sitemesh配置 --> <filter> <filter-name>site-mesh</filter-name> <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class> </filter> <filter-mapping> <filter-name>site-mesh</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- sitemesh servlet配置 --> <servlet> <servlet-name>site-mesh-velocity</servlet-name> <servlet-class>com.opensymphony.module.sitemesh.velocity.VelocityDecoratorServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>site-mesh-velocity</servlet-name> <url-pattern>*.vm</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
4.创建springMvc对应的 springMvc-servlet.xml
<?xml version="1.0" encoding="UTF-8"?> <!--看到下面的beans这个元素标签没有，必须有标签的声明 --> <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"> <!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 --> <context:component-scan base-package="qust.thb.*" /> <!-- 支持spring3.0新的mvc注解 --> <mvc:annotation-driven /> <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer"> <property name="resourceLoaderPath" value="/WEB-INF/"/> <property name="configLocation" value="/WEB-INF/velocity.properties"/> </bean> <!-- 配置内容也可以直接写在该文件内 <bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer" p:resourceLoaderPath="/view"> <property name="velocityProperties"> <props> <prop key="directive.foreach.counter.name">loopCounter</prop> <prop key="directive.foreach.counter.initial.value">0</prop> <prop key="input.encoding">UTF-8</prop> <prop key="output.encoding">UTF-8</prop> </props> </property> </bean> --> <bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver"> <property name="cache" value="true"/> <property name="prefix" value=""/> <property name="suffix" value=".vm"/> </bean> <!--另外一种视图解析器 只是加上前缀、后缀，而不进行视图解析 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/" /> <property name="suffix" value=".vm" /> </bean> --> </beans>
5.在WebContent下创建view文件夹,创建hello.vm
<div> ${message} </div>
6.VelocityConfigurer要加载的velocity.properties文件
# ---------------------------------------------------------------------------- # T E M P L A T E E N C O D I N G # ---------------------------------------------------------------------------- input.encoding=UTF-8 output.encoding=UTF-8 #runtime.log.logsystem.log4j.category=velocity
以上步骤是spring整合velocity
6.在WEB-INF下创建decorators.xml
<?xml version="1.0" encoding="UTF-8"?> <decorators defaultdir="/decorators"> <!-- 此处定义不需要过滤的页面 --> <excludes> </excludes> <!-- 此处用来定义装饰器需要过滤的页面 --> <decorator name="template" page="template.vm"> <pattern>/user/getUser.do</pattern> </decorator> </decorators>
7.在WebContent目录下建立decorators文件夹，创建template.vm文件
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>page include</title> </head> <body> #set($name="hello world nice") $name $body </body> </html>
其中$body即为要加载的hello.vm的内容，剩下的内容可以为hello.vm添加header footer等内容，实现了sitemesh为页面添加统一的导航条，页面首尾等等的功能
将项目部署到tomcat ,访问 http://localhost:8082/SpringMvc/user/getUser.do
页面将会显示：
hello world nice nice to meet you!!!

最后加入:我在搞 maven + springMvc + velocity + sitemesh 搭建一个小项目的时候，sitemesh渲染velocity一直不成功,一直说 Velocity [error] Null reference [template '/decorators/template.vm', line 12, column 9] : $body cannot be resolved. ，改变.vm文件路径或者改变url名字还是没解决，弄了一下午一晚上才找到原因，原来是jar包弄错了
