基于注解的SpringMVC+freemarker环境搭建

首先用IDE建一个web工程。(这个就不详细介绍了)

引入响应的jar包

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>

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>

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>

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

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
