JAVA freemarker (2)---the detailed steps of SPRINGMVC integration Freemarker in idea

First step: Build.gradle configuration introduces jar packs,

Step Two: Create a new Freemarker file freemarker.properties in src/main/resources/conf,

Template_update_delay=0
default_encoding=utf-8
output_encoding=utf-8
number_format=0.##########
classic_compatible=true
template_exception_handler=ignore
locale=zh_cn
date_format=yyyy-mm-dd
time_format=hh:mm:ss
datetime_format=yyyy-mm-dd HH:mm:ss

Step Three: Add Freemarker configuration to Springmvc.xml

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" xmlns:p= "http://www.springframework.org/schema/p" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" Xmlns:contex t= "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.xsd Http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/ Spring-mvc.xsd "> <mvc:annotation-driven/> <context:component-scan base-package=" Com.cloud.wysch "A" > <context:exclude-filter type= "annotation" expression= "Org.springframework.stereotype.Service"/> & Lt;/context:component-scan> <!--set Freemarker configuration filePath--> <bean id= "freemarkerconfiguration" class= " Org.springframework.beans.factory.config.PropertiesFactoryBean "> <property name=" Location "value=" Classpath : Conf/freemarker.properties "/> </bean> <!--Configure Freemarker template path--> <bean id=" Fmxmlescape "cl ass= "Freemarker.template.utility.XmlEscape"/> <bean id= "Freemarkerconfig" class=.

        --Defines the default exception handling page that uses--> <property name= "Defaulterrorview" value= "error" When registering for the exception type ></property> <!--define the name of the variable that the exception-handling page uses to get exception information, the default name is exception--> <property name= "Exceptionattribute" value= "Exception" >&lt ;/property> <!--define exceptions that require special handling, with the class name or full pathname as the key, and the exception page name as the value--> <property name= "Exceptionmappings"
            ; <props> <prop key= "java.lang.Exception" >error</prop> <prop key= "java. LaNg. Throwable ">error</prop> </props> </property> </bean> </beans>

Step Fourth: Write controller and FTL files

Create a new package under the Src/main/java directory Com.cloud.wyscha.base.controller, and under the package, create a new Freemarkcontroller.java, as follows:

@Controller
@RequestMapping ("/freemark") public
class Freemarkcontroller extends Basecontroller {

    @ Requestmapping ("/helloworld.action") public
    Modelandview HelloWorld (httpservletrequest request, HttpServletResponse response) {
        map<string, object> Map = new hashmap<string, object> ();
        Map.put ("Word0", "Hello");
        Map.put ("Word1", "world!");
        return new Modelandview ("HelloWorld", map);
    }

HELLOWORLD.FTL, as follows:

<! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd" >
 
Fifth step: Visit 
Http://localhost/freemark/helloWorld.action
