基于注解的springmvc freemarker环境搭建

1. 首先用ide建一个web工程。(这个就不详细介绍了)
   
2. 引入响应的jar包
   
3. web.xml
   xml version="1.0" ?>
   <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
       xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
       version="3.0">
       
       <context-param>
           <param-name>contextconfiglocationparam-name>
           <param-value>classpath:applicationcontext.xmlparam-value>
       context-param>
       
       
       <listener>
           <listener-class>org.springframework.web.context.contextloaderlistener
           listener-class>
       listener>
   
       <servlet>
           <servlet-name>springmvcservlet-name>
           <servlet-class>org.springframework.web.servlet.dispatcherservlet
           servlet-class>
           <load-on-startup>1load-on-startup>
       servlet>
       
       <servlet-mapping>
           <servlet-name>springmvcservlet-name>
           <url-pattern>/url-pattern>
       servlet-mapping>
   web-app>
   
   
4. springmvc另外一个重要的配置文件。
   dispatcherservlet会根绝web.xml中配置的去找-servlet.xml的文件来加载spring的一些配置信息。我这里就应该取名叫springmvc-servlet.xml
   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:p="http://www.springframework.org/schema/p" 
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemalocation="http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context-2.5.xsd">
       
       
       <context:component-scan base-package="com.liba.spring.mvc"/>
       
       
       <bean class="org.springframework.web.servlet.mvc.annotation.annotationmethodhandleradapter" />
       
           
   
       
       
       
       
       <bean id="viewresolver"
           class="org.springframework.web.servlet.view.freemarker.freemarkerviewresolver">
           <property name="cache" value="true" />
           <property name="prefix" value="" />
           <property name="suffix" value=".ftl" />
           <property name="contenttype" value="text/html;charset=utf-8">property>
           <property name="requestcontextattribute" value="request" />
           <property name="exposespringmacrohelpers" value="true" />
           <property name="exposerequestattributes" value="true" />
           <property name="exposesessionattributes" value="true" />
       bean>
           
           
       
       
       
   beans>
   
   
5. 如果是使用freemarker最为视图模板需要再spring的配置文件applicationcontext.xml中加入以下配置
   <bean id="freemarkerconfig"
           class="org.springframework.web.servlet.view.freemarker.freemarkerconfigurer">
           <property name="templateloaderpath" value="/web-inf/view/" />
           <property name="freemarkersettings">
               <props>
                   <prop key="template_update_delay">0prop>
                   <prop key="default_encoding">utf-8prop>
                   <prop key="number_format">0.##########prop>
                   <prop key="datetime_format">yyyy-mm-dd hh:mm:ssprop>
                   <prop key="classic_compatible">trueprop>
                   <prop key="template_exception_handler">ignoreprop>
               props>
           property>
       bean>
   
   
6. controller建立
   import javax.servlet.http.httpservletrequest;
   
   import org.springframework.stereotype.controller;
   import org.springframework.web.bind.annotation.requestmapping;
   import org.springframework.web.bind.annotation.requestmethod;
   import org.springframework.web.servlet.modelandview;
   
   @controller
   public class springmvccontroller {
   
       @requestmapping(value="/welcome",method={requestmethod.get}) 
       public modelandview getfirstpage(httpservletrequest request) {
                   //welcom就是视图的名称（welcom.ftl）
           modelandview mv = new modelandview("welcom");
           mv.addobject("name", "my first spring mvc");
           return mv;
       }
   }
   在url上敲http://localhost:8080/welcome就会到web-inf/view/welcom.ftl页面渲染数据
   
7. welcom.ftl页面
   doctype html public "-//w3c//dtd html 4.01 transitional//en" "http://www.w3.org/tr/html4/loose.dtd">
   <html>
   <head>
   <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">
   <title>insert title heretitle>
   head>
   <body>
   hello ${name}
   body>
   html>
   
   页面出来的效果：
   
   hello my first spring mvc
