FreeMarker做爲模板引擎，是比較經常使用的。html

FreeMarker官方文檔地址爲:https://freemarker.apache.org/java

如今瀏覽器或者翻譯工具這麼多，對於英文方面，我想大多數每天敲代碼的，奮戰在前線的同志們，對於不少編程實用單詞應該不陌生，若是語文老師不是XX老師教的，我想經過Google或者其餘翻譯工具翻譯一些意思，我想你們應該是能夠看的懂，和判斷是否存在問題的。mysql

 

其實我我的英語，也不怎麼樣，曾經就採起過這樣一種策略，來記單詞，稱之爲"趣味單詞記錄法"，這個法，我想只要將Good morning 讀成鬼德莫你的人，應該可以很好的體會這種樂趣，記得正是這種樂趣，使我從學校到如今工做，對於英語也不是特別恐懼，固然了，這樣也會致使不少問題，好比發音不標準等等。web

這裏不做討論，這裏想表達的仍是但願，計算機專業的同胞或者其餘轉行或者感興趣的朋友們，不要由於英語而中止對其研究學習或者放棄。redis

 

好比那些常見的Java代碼生成器，基本都是經過編寫ftl文件，也就是FreeMarker模板文件，經過調用對應的方法來達到代碼生成的目的。spring

其實FreeMarker同JSP或者Volocity整合SpringMVC，並沒有多大的區別，web.xml基本都是那一套。sql

spring.xml配置的基本是掃描dao，掃描service，整合MyBatis或MyBatis Plus和配置數據源管理和使用xml或者事務註解等，若是要用到shiro或redis，也就至關於配置對應的bean。apache

關於Spring+SpringMVC+MyBatis整合實例或Spring+SpringMVC+MyBatis Plus整合實例，你們能夠參考個人以下幾篇博文:編程

MP實戰系列(一)之入門框架搭建和使用json

ssm框架整合+Ajax異步驗證

maven中ssm框架快速搭建

若是你是使用或者想學習SpringBoot，能夠參考以下個人幾篇博文:

MP實戰系列(七)之集成springboot

或者個人SpringBoot實戰系列文章

固然，這些都是基於SpringBoot官方文檔相關的示例+我我的一些想法和理解。

 

下面進入整合實例:

2、編寫Spring-MVC對應的配置文件

<?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:p="http://www.springframework.org/schema/p"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
        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-4.0.xsd">

    <!-- 掃描Controller層 -->
    <context:component-scan base-package="com.freemark.controller"/>


    <!-- 靜態資源不攔截放行 -->
    <mvc:default-servlet-handler/>

    <!-- 開啓註解 -->
    <mvc:annotation-driven />

        <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><!-- 時間格式化 -->
                <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="" /><!-- 上面已經配了，這裏就不用配啦 -->
        <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>

 

3、修改web.xml

<?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_2_5.xsd" version="2.5">
  <display-name>test</display-name>



  <filter>
    <filter-name>CharacterEncoding</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <servlet>
    <description>spring mvc servlet</description>
    <servlet-name>springMvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>


 


</web-app>

 

4、編寫對應的Controller代碼

package com.freemark.controller;

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

@Controller
public class TestController {
    
    @GetMapping(value="test")
    public String test(Model model) {
        model.addAttribute("userName", "張三");
        return "test";
    }

}

 

5、在WEB-INF目錄下新建ftl文件夾並在此文件夾下新建test.ftl文件

test.ftl

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
${userName}
</body>
</html>

 

 

完成上述步驟，啓動項目,並在瀏覽器輸入對應的url，瀏覽器正確返回視圖，控制檯無報錯，表示整合成功。

說明:這次演示只是針對SpringMVC+FreeMarker

若是你想加入Spring+MySQL或者Redis+Shiro，能夠增長對應的配置文件和相關依賴

簡單的說，若是你想用FreeMarker，不使用JSP或者其餘模板，你只需修改對應的Spring-MVC的配置文件便可，並引入對應的maven依賴。

最後寫個簡單的測試便可，測試是否合法沒問題。
