spring使用freemarker

一、配置xml

　　修改spring的初始化xml文件

<?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:aop="http://www.springframework.org/schema/aop" xmlns:task="http://www.springframework.org/schema/task"
    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/aop http://www.springframework.org/schema/aop/spring-aop.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd
            http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">  

    <!-- 配置freemarker -->
    <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/pages/" />
        <property name="freemarkerSettings">
            <props><prop key="defaultEncoding">UTF-8</prop></props>
        </property>
    </bean>
    <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="suffix" value=".ftl" />
        <property name="contentType" value="text/html; charset=UTF-8" />
    </bean>
</beans>

　　这个配置说明，Freemarker的模板文件放在/WEB-INF/pages/目录下，以.ftl后缀结束，如下图

二、使用freemarker

　　创建index.ftl和login.ftl两个文件，如上图，两个文件内容都只有一行，分别是index page和login page。

　　创建一个controller

package org.demo.controller;  

import javax.servlet.http.HttpServletRequest;  

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

@Controller
public class SSOServerController {
    @RequestMapping("/index")
    public String index(HttpServletRequest req, Model model) {
        return "index";
    }
}

　　配置spring扫描controller。在spring配置文件中添加如下两行

<context:component-scan base-package="org.demo.controller" />
<mvc:annotation-driven/>

　　启动项目，在浏览器访问
