本文介绍如何在SpringMVC框架中整合Freemarker模板引擎，并通过具体步骤及代码示例展示了完整的实现过程。

整合过程如下：

1.新建一个maven web工程，使用maven依赖spring,springmvc,freemarker的相关jar,建好后的项目目录如下：
这里写图片描述

pom.xml文件中的配置如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ffcs.oss</groupId> <artifactId>SpringMVC_Freemarker</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <org.springframework.version>4.1.6.RELEASE</org.springframework.version> <freemarker.version>2.3.23</freemarker.version> </properties> <dependencies> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>${freemarker.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework.version}</version> </dependency> </dependencies> </project>

2.配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc_freemarker.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>

3.配置springmvc和freemarker整合的配置文件springmvc_freemarker.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <context:component-scan base-package="com.ffcs"></context:component-scan> <mvc:annotation-driven></mvc:annotation-driven> <bean id="freeMarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/ftl/"></property> <property name="defaultEncoding" value="utf-8" /> <property name="freemarkerSettings"> <props> <prop key="template_update_delay">1</prop> <prop key="locale">zh_CN</prop> <prop key="datetime_format">yyyy-MM-dd</prop><!-- 时间格式化 --> <prop key="date_format">yyyy-MM-dd</prop> <prop key="number_format">#.##</prop> </props> </property> </bean> <bean id="freeMarkerViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="cache" value="true" /> <property name="prefix" value="" /><!-- 上面已经配了，这里就不用配啦 --> <property name="suffix" value=".ftl" /> <property name="contentType" value="text/html;charset=UTF-8" /> <property name="allowSessionOverride" value="true" /> <property name="allowRequestOverride" value="true" /> <property name="exposeSpringMacroHelpers" value="true" /> <property name="exposeRequestAttributes" value="true" /> <property name="exposeSessionAttributes" value="true" /> <property name="requestContextAttribute" value="request" /> </bean> </beans>

4.在WEB-INF/ftl/目录下新建一个freemarker的模板文件may.ftl，内容如下：

User:<br/>
${user.name}--->${user.age}<br/>
List:<br/> <#list list as item > <font color="red">${item}</br></font> </#list> param:</br> ${RequestParameters.a}&nbsp;a=${param!}

5.编写User和TestFreemarker这两个类，代码如下所示：
User类：

package com.ffcs.oss.domain;

import java.io.Serializable;

public class User implements Serializable { /** * */ private static final long serialVersionUID = 1L; private String name; private Integer age; public User() { super(); } public User(String name, Integer age) { super(); this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }

TestFreemarker类：

package com.ffcs.oss.controller; import java.util.ArrayList; import java.util.List; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.servlet.ModelAndView; import com.ffcs.oss.domain.User; @Controller @RequestMapping(value = "/Freemarker") public class TestFreemarker { @RequestMapping(value = "/testFreemarker") @ResponseBody public ModelAndView testFreemarker(@RequestParam(value = "a", required = false) String a) throws Exception { ModelAndView mv = new ModelAndView(); User user = new User("may", 21); List<String> list = new ArrayList<String>(); list.add("Jack1"); list.add("Jack2"); list.add("Jack3"); mv.addObject("list", list); mv.addObject("user", user); mv.addObject("param", new String(a.getBytes("iso8859-1"), "utf-8")); mv.setViewName("may"); return mv; } }
