SpringMVC整合Freemarker(含Demo源码)

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：



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>
${RequestParameters.a} a=${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;
}
}

6.将项目布署到tomcat运行起来，项目启动如果没有报错，那么打开浏览器，输入URL:

http://localhost:8080/SpringMVC_Freemarker/Freemarker/testFreemarker?a=123

,回车后效果图如下所示：



到此为止，已经成功整合了SpringMVC和Freemarker！下面附上Demo源码的下载地址：
