FreeMarker整合Spring 3
来源:互联网 发布:做淘宝云客服工资多少 编辑:程序博客网 时间:2024/05/22 21:31
开发环境:
System:Windows
WebBrowser:IE6+、Firefox3+
JavaEE Server:tomcat5.0.2.8、tomcat6
IDE:eclipse、MyEclipse 8
开发依赖库:
JavaEE5、Spring 3.0.0.M4、FreeMarker 2.3.16
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.RELEASE
FreeMarker 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" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> --> <!-- annotation默认的方法映射适配器 --> <bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" 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:ss
6、 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" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="location" value="classpath:freemarker.properties"/></bean> <!-- 配置freeMarker的模板路径 --><bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <!--property name="freemarkerSettings" 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" class="freemarker.template.utility.XmlEscape"/> <!-- 配置freeMarker视图解析器 --><bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="viewClass" 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!~.~
