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:

clip_image002

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_detect
template_update_delay=2
default_encoding=UTF-8
output_encoding=UTF-8
locale=zh_CN
date_format=yyyy-MM-dd
time_format=HH:mm:ss
datetime_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!~.~
