Question

springframework freemarker 在哪个包里

Answer 1

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：
<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="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-scanbase-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 -->
<beanid="handlerMapping"
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
<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 >
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 -->
<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">
<!--property name="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>say hello ${name}</h1><br/>
${(1 == 1)?string("yes", "no")}
</body>
</html>
hi.ftl
<html>
<body>
<h1>say hello ${name}</h1><br/>
${(1 != 1)?string("yes", "no")}
</body>
</html>
8、 添加Controller控制器，代码如下：
packagecom.hoo.controller;
importorg.springframework.stereotype.Controller;
importorg.springframework.ui.ModelMap;
importorg.springframework.web.bind.annotation.RequestMapping;
/**
* <b>function:</b> FreeMarker示例控制器
* @author hoojo
* @createDate 2011-3-3 下午04:50:10
* @file HelloWorldController.java
* @package com.hoo.controller
* @project SpringFreemarker
* @version 1.0
*/
@Controller
@RequestMapping("/freeMarker")
publicclassHelloWorldController {
@RequestMapping("/hello")
publicString sayHello(ModelMap map) {
System.out.println("say Hello ……");
map.addAttribute("name", " World!");
return"/hello.ftl";
}
@RequestMapping("/hi")
publicString sayHi(ModelMap map) {
System.out.println("say hi ……");
map.put("name", "jojo");
return"/hi.ftl";
}
@RequestMapping("/jsp")
publicString jspRequest(ModelMap map) {
System.out.println("jspRequest ……");
map.put("name", "jsp");
return"/temp.jsp";
}
}
9、 添加index.jsp的测试链接或temp.jsp的内容：
index.jsp
<body>
<ahref="freeMarker/hello.do">say hello</a><br/>
<ahref="freeMarker/hi.do">say hi</a><br/>
<ahref="freeMarker/jsp.do">jspRequest</a>
</body>
temp.jsp
<body>
<h3>${name }</h3>
</body>
如果运行无错误，并输出正确的结果就整合成功！
