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

<dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-lgpl</artifactId> <version>1.9.13</version></dependency><dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>3.1.0.RELEASE</version></dependency><dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.1.0.RELEASE</version></dependency><dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version></dependency><dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope></dependency><dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.5</version> <scope>provided</scope></dependency><dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.36</version></dependency><dependency> <groupId>commons-dbutils</groupId> <artifactId>commons-dbutils</artifactId> <version>1.5</version></dependency><dependency> <groupId>commons-pool</groupId> <artifactId>commons-pool</artifactId> <version>1.6</version></dependency><dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>20030825.184428</version></dependency><dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.28</version></dependency><dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.20</version></dependency><dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version></dependency>

3.配置web.xml

<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>  <servlet><servlet-name>springMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><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>  <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>  <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:
