freemarker项目实践
freemarker项目演示
一 Java项目演示
1.首先创建Java项目，整个项目如图所示
2.导入freemarker包
3.编写*.ftl文件(例如:hello.ftl)
4.编写测试类(例如:TestFreemarker.java)
5.运行测试类，效果如图:
二 web项目演示
1.首先创建web项目，整个项目如图所示:
2.导入freemarker包
3.创建实体类user
4.配置web.xml
5.编写测试类:(FreeMarkerHandler.java)
6.index,jsp
<body>
点击下面链接查看效果:
<hr>
<a href="FreemarkerHandler.do">查看效果</a>
</body>
7.编写*.ftl文件(例如:templates包下的hello.ftl文件)
8.运行测试如图所示:
三 spring项目演示
1.首先创建spring项目，整个项目如图所示
2.在pom.xml中下载spring及freemarker所需要的包

3.配置web.xml
| <!-- spring 的编码过滤器 --> | |
| <filter> | |
| <filter-name>CharacterEncodingFilter</filter-name> | |
| <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> | |
| <init-param> | |
| <param-name>encoding</param-name> | |
| <param-value>UTF-8</param-value> | |
| </init-param> | |
| </filter> | |
| <filter-mapping> | |
| <filter-name>CharacterEncodingFilter</filter-name> | |
| <url-pattern>/*</url-pattern> | |
| </filter-mapping> | |
| <!-- 配置springMVC的核心控制器 --> | |
| <servlet> | |
| <servlet-name>springMVC</servlet-name> | |
| <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> | |
| <!-- 配置 Spring-mvc.xml 文件位置 --> | |
| <init-param> | |
| <param-name>contextConfigLocation</param-name> | |
| <param-value>classpath:spring-mvc.xml</param-value> | |
| </init-param> | |
| </servlet> | |
| <servlet-mapping> | |
| <servlet-name>springMVC</servlet-name> | |
| <url-pattern>/</url-pattern> | |
| </servlet-mapping> | |
| <!-- 配置spring Start --> | |
| <context-param> | |
| <param-name>contextConfigLocation</param-name> | |
| <param-value>classpath:spring.xml</param-value> | |
| </context-param> | |
| <listener> | |
| <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> | |
| </listener> | |
| <!-- 欢迎页面 --> | |
| <welcome-file-list> | |
| <welcome-file>index.jsp</welcome-file> | |
| </welcome-file-list> |
4.配置spring-mvc.xml文件以及spring.xml
spring-mvc.xml
spring.xml(因为无所连接数据库测试所以spring.xml无需配置)
5.编写测试类
6.编写*.ftl文件(例如:helle.ftl)
7.运行测试如图所示:
