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">
       <!--  Spring 服务层的配置文件 -->
       <context-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:applicationContext.xml</param-value>
       </context-param>
       
       <!--  Spring 容器启动监听器 -->
       <listener>
           <listener-class>org.springframework.web.context.ContextLoaderListener
           </listener-class>
       </listener>
   
       <servlet>
           <servlet-name>springmvc</servlet-name>
           <servlet-class>org.springframework.web.servlet.DispatcherServlet
           </servlet-class>
           <load-on-startup>1</load-on-startup>
       </servlet>
       <!--为DispatcherServlet建立映射 -->
       <servlet-mapping>
           <servlet-name>springmvc</servlet-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<servlet-name>去找<servlet-name>-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">
       
       <!--对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
       <context:component-scan base-package="com.liba.spring.mvc"/>
       
       <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射   请求映射-->
       <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
       
           <!--以下三种视图配置根据需要任选一种即可 -->
   
       <!--  一般的视图配置 -->
       <!--<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
           p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>-->
       
       <!-- 针对freemarker的视图配置 -->
       <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>
           
           
       <!-- View resolvers can also be configured with ResourceBundles or XML files. 
           If you need different view resolving based on Locale, you have to use the 
           resource bundle resolver. -->
       <!-- 这个是针对返回视图还是json值的视图配置   来分别处理同步和异步请求 -->
       <!--<bean
               class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
               <property name="mediaTypes">
                   <map>
                       <entry key="html" value="text/html" />
                       <entry key="json" value="application/json" />
                   </map>
               </property>
               <property name="favorParameter" value="true" />
               <property name="viewResolvers">
                   <list>
                       <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" />
                       <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>
                   </list>
               </property>
               <property name="defaultContentType" value="text/html" />
           </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">0</prop>
                   <prop key="default_encoding">UTF-8</prop>
                   <prop key="number_format">0.##########</prop>
                   <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
                   <prop key="classic_compatible">true</prop>
                   <prop key="template_exception_handler">ignore</prop>
               </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 here</title>
   </head>
   <body>
   Hello ${name}
   </body>
   </html>
   
   页面出来的效果：
   
   Hello My First Spring Mvc
