SpringMVC整合Freemarker(含Demo源码)(转)

转自：http://blog.csdn.net/sinat_27535209/article/details/61199452

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">

    <properties>

    </properties>
    <dependencies>

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;
    }
}

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：
