FreeMarker整合Spring 3
开发环境：System：WindowsWebBrowser：IE6+、Firefox3+JavaEE Server：tomcat5.0.2.8、tomcat6IDE：eclipse、MyEclipse 8开发依赖库：JavaEE5、Spring 3.0.0.M4、FreeMarker 2.3.16Email：hoojo_@126.comBlog：http://blog.csdn.net/IBM_hoojohttp://hoojo.cnblogs.com/ 1、 新建WebProject，工程名称是SpringFreemarker；然后手动添加jar包，需要的jar包如下：SpringFramework jar包下载地址：http://ebr.springsource.com/repository/app/library/version/detail?name=org.springframework.spring&version=3.0.5.RELEASEFreeMarker library下载地址：http://ebr.springsource.com/repository/app/bundle/version/detail?name=com.springsource.freemarker&version=2.3.15当然你也可以去官方下载2、 在web.xml中添加如下配置： <!-- 加载Spring容器配置 --><listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 设置Spring容器加载配置文件路径 --><context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:applicationContext-*.xml</param-value></context-param> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/dispatcher.xml</param-value> </init-param> <load-on-startup>1</load-on-startup></servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.do</url-pattern></servlet-mapping>上面分别是添加Spring的监听器、以及配置Spring的配置文件、还有SpringMVC的控制器；3、 在WEB-INF中添加文件dispatcher.xml，和web.xml中的对应。内容如下： <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans > http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd" <context:component-scan base-package="com.hoo" /> <!-- annotation的方法映射适配器 <bean id="handlerAdapter" value="org.springframework.web.servlet.view.JstlView"/> </bean> </beans> 上面是SpringMVC的基本配置4、 在src中添加applicationContext-beans.xml，内容如下： <?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans > http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"</beans>里面可以添加一些bean的配置5、 在src目录添加freemarker.properties配置文件，这个文件是freemarker一些常用的转换，内容如下： tag_syntax=auto_detecttemplate_update_delay=2default_encoding=UTF-8output_encoding=UTF-8locale=zh_CNdate_format=yyyy-MM-ddtime_format=HH:mm:ssdatetime_format=yyyy-MM-dd HH:mm:ss6、 在dispatcher.xml中添加freemarker的配置，配置如下： <!-- 设置freeMarker的配置文件路径 --><bean id="freemarkerConfiguration" value="classpath:freemarker.properties"/></bean> <!-- 配置freeMarker的模板路径 --><bean id="freemarkerConfig" ref="freemarkerConfiguration"/--> <property name="templateLoaderPath"> <value>/WEB-INF/ftl/</value> </property> <property name="freemarkerVariables"> <map> <entry key="xml_escape" value-ref="fmXmlEscape" /> </map> </property></bean> <bean id="fmXmlEscape" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/> <property name="viewNames" value="*.ftl"/> <property name="contentType" value="text/html; charset=utf-8"/> <property name="cache" value="true" /> <property name="prefix" value="" /> <property name="suffix" value="" /> <property name="order" value="2"/></bean>上面最关键的就是freeMarker的视图解析器viewResolver的配置，viewClass是使用哪个视图解析器，这里是类路径；其他的和jsp的视图解析器都很类似。7、 下面在WEB-INF中添加2个ftl模板，在WEB-INF添加ftl，然后添加hello.ftl/hi.ftl，内容分别是：hello.ftl <html><body> <h1>say hello ${name}</h1><br/> ${(1 == 1)?string("yes", "no")}</body></html>hi.ftl <html><body> <h1>say hello ${name}</h1><br/> ${(1 != 1)?string("yes", "no")}</body></html>8、 添加Controller控制器，代码如下： package com.hoo.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping; /** * <b>function:</b> FreeMarker示例控制器 * @author hoojo * @createDate 2011-3-3 下午04:50:10 * @file HelloWorldController.java * @package com.hoo.controller * @project SpringFreemarker * @version 1.0 */@Controller@RequestMapping("/freeMarker")public class HelloWorldController { @RequestMapping("/hello") public String sayHello(ModelMap map) { System.out.println("say Hello ……"); map.addAttribute("name", " World!"); return "/hello.ftl"; } @RequestMapping("/hi") public String sayHi(ModelMap map) { System.out.println("say hi ……"); map.put("name", "jojo"); return "/hi.ftl"; } @RequestMapping("/jsp") public String jspRequest(ModelMap map) { System.out.println("jspRequest ……"); map.put("name", "jsp"); return "/temp.jsp"; }}9、 添加index.jsp的测试链接或temp.jsp的内容：index.jsp <body> <a href="freeMarker/hello.do">say hello</a><br/> <a href="freeMarker/hi.do">say hi</a><br/> <a href="freeMarker/jsp.do">jspRequest</a></body>temp.jsp <body> <h3>${name }</h3></body>如果运行无错误，并输出正确的结果就整合成功！~.~?
