FreeMarker整合Spring mvc

-->

<!--annotation默认的方法映射适配器-->

<beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver">

<propertyname="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：

<?xmlversion="1.0"encoding="UTF-8"?>

<beansxmlns="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>

'target='_blank'>http://www.springframework.org/schema/beans/spring-beans-3.0.xsd[/code]
http://www.springframework.org/schema/aop

'target='_blank'>http://www.springframework.org/schema/aop/spring-aop-3.0.xsd[/code]
http://www.springframework.org/schema/tx

'target='_blank'>http://www.springframework.org/schema/tx/spring-tx-3.0.xsd[/code]
http://www.springframework.org/schema/util

'target='_blank'>http://www.springframework.org/schema/util/spring-util-3.0.xsd[/code]
http://www.springframework.org/schema/context

'target='_blank'>http://www.springframework.org/schema/context/spring-context-3.0.xsd"[/code]
</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-ddHH: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-->

<beanid="freemarkerConfiguration"class="org.springframework.beans.factory.config.PropertiesFactoryBean">

<propertyname="location"value="classpath:freemarker.properties"/>

</bean>


<!--配置freeMarker的模板路径-->

<beanid="freemarkerConfig"class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

<!--propertyname="freemarkerSettings"ref="freemarkerConfiguration"/-->

<propertyname="templateLoaderPath">

<value>/WEB-INF/ftl/</value>

</property>

<propertyname="freemarkerVariables">

<map>

<entrykey="xml_escape"value-ref="fmXmlEscape"/>

</map>

</property>

</bean>


<beanid="fmXmlEscape"class="freemarker.template.utility.XmlEscape"/>


<!--配置freeMarker视图解析器-->

<beanid="viewResolver"class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

<propertyname="viewClass"value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/>

<propertyname="viewNames"value="*.ftl"/>

<propertyname="contentType"value="text/html;charset=utf-8"/>

<propertyname="cache"value="true"/>

<propertyname="prefix"value=""/>

<propertyname="suffix"value=""/>

<propertyname="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>sayhello${name}</h1><br/>

${(1==1)?string("yes","no")}

</body>

</html>


hi.ftl

<html>

<body>

<h1>sayhello${name}</h1><br/>

${(1!=1)?string("yes","no")}

</body>

</html>


8、添加Controller控制器，代码如下：

packagecom.hoo.controller;


importorg.springframework.stereotype.Controller;

importorg.springframework.ui.ModelMap;

importorg.springframework.web.bind.annotation.RequestMapping;


/**

*<b>function:</b>FreeMarker示例控制器

*@authorhoojo

*@createDate2011-3-3下午04:50:10

*@fileHelloWorldController.java

*@packagecom.hoo.controller

*@projectSpringFreemarker

*@version1.0

*/

@Controller

@RequestMapping("/freeMarker")

publicclassHelloWorldController{


@RequestMapping("/hello")

publicStringsayHello(ModelMapmap){

System.out.println("sayHello……");

map.addAttribute("name","World!");

return"/hello.ftl";

}


@RequestMapping("/hi")

publicStringsayHi(ModelMapmap){

System.out.println("sayhi……");

map.put("name","jojo");

return"/hi.ftl";

}


@RequestMapping("/jsp")

publicStringjspRequest(ModelMapmap){

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>

<ahref="freeMarker/hello.do">sayhello</a><br/>

<ahref="freeMarker/hi.do">sayhi</a><br/>

<ahref="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！~.~
