Freemarker is a template engine written in the Java language that generates text output based on a template. Freemarker is not related to the Web container, that is, when the web is running, it does not know the servlet or HTTP. Not only can it be used as a performance layer implementation technology, but also can be used to generate xml,jsp or Java.
In short, Freemarker is a template in the Jave Web launch to display information from the server in a format.
Step1. Introducing Jar Packs
Maven Codes :
Copy Code code as follows:
<!--freemarker-->
<dependency>
<groupId>org.freemarker</groupId>
<artifactid>freemarker</artifactid >
<version>2.3.20</version>
</dependency>
<!--ui.freemarker -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version> 3.2.4.release</version>
</dependency>
step2. In src/main/resources/ Conf document under the new Freemarker freemarker.properties, this document defines the freemarker commonly used code conversion , the code is as follows:
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
step3. In DispatcherservletThe configuration required to add Freemarker to the context configuration file Spring-servlet.xml is as follows:
Copy Code code as follows:
<!--configuration of freemarker file path-->
<bean id= "freemarkerconfiguration" class= "Org.springframework.beans.factory.config.PropertiesFactoryBean" >
<property name= "Location" value= "Classpath:conf/freemarker.properties"/>
</bean>
<!--Configure Freemarker template add address-->
<bean id= "Freemarkerconfig" class= "Org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer" >
<!--The video parser scans the file in the/web-inf/ftl/path-->
<property name= "Templateloaderpath" value= "/web-inf/ftl/"/>
<property name= "Freemarkervariables" >
<map>
<entry key= "Xml_escape" value-ref= "Fmxmlescape"/>
</map>
</property>
</bean>
<bean id= "Fmxmlescape" class= "Freemarker.template.utility.XmlEscape"/>
<!--configuration Freemarker Video parser-->
<bean id= "Freemakerviewresolver" class= " Org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver ">
<property name= "Viewclass" value= "Org.springframework.web.servlet.view.freemarker.FreeMarkerView"/>
<!--scans all FTL end files-->
<property name= "Viewnames" >
<array>
<value>*.ftl</value>
</array>
</property>
<property name= "ContentType" value= "text/html; Charset=utf-8 "/>
<property name= "Exposerequestattributes" value= "true"/>
<property name= "Exposesessionattributes" value= "true"/>
<property name= "Exposespringmacrohelpers" value= "true"/>
<property name= "Requestcontextattribute" value= "Request"/>
<!--to the image parser to configure the priority, you can give the previous JSP image parser value of 2-->
<property name= "Order" value= "1"/>
</bean>
step4. Edit controller files and FTL files
In the Src/main/java, new package Www.asuan.com.controller under the package, the new Helloworldcontroller.java, the code is as follows:
Copy Code code as follows:
Package Www.asuan.com.controller;
Import Org.springframework.stereotype.Controller;
Import Org.springframework.ui.Model;
Import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class Helloworldcontroller {
@RequestMapping ("/helloworld")
Public String HelloWorld (model model) {
String word0 = "Hello";
String word1 = "world!";
Add data to the visual data container
Model.addattribute ("word0", word0);
Model.addattribute ("Word1", word1);
return "HELLOWORLD.FTL";
}
}
In the STEP3 configuration of the WEB-INF/FTL path under the new HELLOWORLD.FTL, the code is as follows:
Copy Code code as follows:
<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "HTTP://WWW.W3.ORG/TR/HTML4/LOOSE.DTD" >
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 ">
<title>insert title here</title>
<body>
</body>
Step5. Running and tuning
Deploy the project to Tomcat and run, and interview in the browser: http://localhost:8080/the project name you set/helloworld.htm
Running results:
