Maven+SpringMVC+Freemarker入门Demo

1 参考http://blog.csdn.net/haishu_zheng/article/details/51490299，用第二种方法创建一个名为mavenspringmvcfreemarker的Maven工程。

 

2 文件目录结构如下图所示

3 在pom.xml中添加springmvc和freemarker的依赖包，添加完之后的完整内容为

4 web.xml中的完整内容为

5 spring-servlet.xml中的完整内容为：

 

<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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:component-scan base-package="com.demo" />

    <bean
        class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

    <!-- 配置Freemarker属性文件路径 -->
    <bean id="freemarkerConfiguration"
        class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:conf/freemarker.properties" />
    </bean>
    <!-- 配置freeMarker模板加载地址 -->
    <bean id="freemarkerConfig"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <!-- 视图解析器在/WEB-INF/ftl/路径下扫描视图文件 -->
        <property name="templateLoaderPath" value="/WEB-INF/ftl/" />
        <property name="freemarkerVariables">
            <map>
                <entry key="xml_escape" value-ref="fmXmlEscape" />

        <property name="exposeSessionAttributes" value="true" />
        <property name="exposeSpringMacroHelpers" value="true" />
        <property name="requestContextAttribute" value="request" />
        <!-- 给视图解析器配置优先級，你可以给之前jsp视图解析器的值配为2 -->
        <property name="order" value="1" />
    </bean>

</beans>

注意：web.xml中，有个<servlet-name>为spring，所以这个文件起名为spring-servlet.xml。这样，程序自动会去加载spring-servlet.xml。也就说<xxx>-servlet.xml中的<xxx>必须与<servlet-name>的值完全对应。

不对应当然也可以，但是要在web.xml中显示指定加载。

比如：把spring-servlet.xml改名为applicationContext.xml，则要在web.xml中的</servlet-class>下方加代码：

 

<init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</init-param>

6 freemarker.properties中的完整内容为

 

tag_syntax=auto_detect
template_update_delay=2
default_encoding=UTF-8
output_encoding=UTF-8
locale=zh_CN
date_format=yyyy-MM-dd
time_format=HH:mm:ss
datetime_format=yyyy-MM-dd HH:mm:ss

7 StudentController.java中的完整代码为：

package com.demo.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.ui.Model;

@Controller
public class StudentController {

    @RequestMapping("/helloWorld")
    public String helloWorld(Model model) {
        String word0 = "Hello ";
        String word1 = "World!";
        //将数据添加到视图数据容器中
        model.addAttribute("word0",word0);
        model.addAttribute("word1",word1);
        return "Hello.ftl";
    }
}

8 Hello.ftl中的完整代码为：

 

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>

9 将mavenspringmvcfreemarker添加进Tomcat 7中并运行

在浏览器中输入

http://localhost:8080/mavenspringmvcfreemarker/helloWorld

显示结果为
