spring与freemarker整合

一、配置环境

使用maven管理工具导入jar包

<properties>    <webVersion>3.1</webVersion>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <spring-version>4.3.5.RELEASE</spring-version></properties><dependencies>    <!-- spring 依赖 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-expression</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-oxm</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aop</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context-support</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aspects</artifactId>      <version>${spring-version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-orm</artifactId>      <version>${spring-version}</version>    </dependency>    <!--freemarker的包-->    <dependency>      <groupId>org.freemarker</groupId>      <artifactId>freemarker</artifactId>      <version>2.3.23</version>    </dependency></dependencies>

配置文件：
这里的配置大体上与springmvc差不多，主要的区别是将springmvc的视图解析器改为freemarker的视图解析，另外添加freemarkerConfig的配置，大体的配置如下：spring-freemarker.xml

<!-- 组件扫描 --><context:component-scan base-package="com.wqh.action"/><!-- 使用注解开发 --><mvc:annotation-driven/><!-- 视图解析器 --><!-- 使用freemarker的视图配置 --><bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">    <!--是否开启缓存-->    <property name="cache" value="true"/>    <!--前缀-->    <property name="prefix" value=""/>    <!--视图层的后缀，这里是返回到.html的页面，也可以改为模板文件的后缀.ftl-->    <property name="suffix" value=".html"/>    <property name="contentType" value="text/html;charset=UTF-8"></property>    <property name="requestContextAttribute" value="request"/>    <property name="exposeSpringMacroHelpers" value="true"/>    <property name="exposeRequestAttributes" value="true"/>    <property name="exposeSessionAttributes" value="true"/></bean><bean id="freemarkerConfig"      class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">    <!--扫描freemarker的模板文件所在的位置-->    <property name="templateLoaderPath" value="/" />    <property name="freemarkerSettings">        <props>            <!--更新模板的时间-->            <prop key="template_update_delay">0</prop>            <!--编码格式-->            <prop key="default_encoding">UTF-8</prop>            <!--数据格式化的配置-->            <prop key="number_format">0.##########</prop>            <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>            <prop key="classic_compatible">true</prop>            <prop key="template_exception_handler">ignore</prop>        </props>    </property></bean>

web.xml的配置：这里大致上与springmvc相同

<!-- 使用通配符*加载spring的配置问件 --><context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:spring/applicationContext.xml</param-value></context-param><listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 定义拦截器，解决post乱码 --><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><!-- 前端控制器 --><servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>        <param-name>contextConfigLocation</param-name>        <!-- 配置文件 -->        <param-value>classpath:spring/spring-freemarker.xml</param-value>    </init-param></servlet><servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>*.action</url-pattern></servlet-mapping>

整个项目：

其他层这里就不配置了

二、action方法

@RequestMapping("/freemark")public ModelAndView testFreeMark(){    ModelAndView modelAndView = new ModelAndView();    User user = new User();    user.setId("dfsd");    user.setContent("sdsd");    user.setName("sdssxcv");    modelAndView.addObject("user",user);   return modelAndView;}

页面

<html><head>    <title>Title</title></head><body>    id:${user.id}    name:${user.name}    content:${user.content}    <!--定义变量-->    <#assign index=1/>    <!--变量的使用-->    ${index}</body></html>
