springmvc从控制类跳转到html的视图解析

转自开源中国的一位作者的文章，稍加改造后

局部框架springmvc+mybatis+html(解决springmvc从控制类跳转到html的视图解析)

1.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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"> 
   <!-- 指定欢迎页面 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
<!-- 字符集过滤器  编码格式 解决从页面传过来的字符编码格式 -->
<filter>
   <filter-name>characterEncodingFilter</filter-name>
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>

    <param-value>true</param-value>
    </init-param>    
</filter>
<filter-mapping>
   <filter-name>characterEncodingFilter</filter-name>
   <url-pattern>/*</url-pattern>
 </filter-mapping>
    <context-param>
     <param-name>log4jConfigLocation</param-name>
     <param-value>WEB-INF/log4j.properties</param-value>
 </context-param>  
 <!-- 定义LOG4J监听器-->
    <listener>
        <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
   </listener> 
<!-- 部署applicationContext文件-->
      <servlet>
        <servlet-name>contextConfigLocation</servlet-name>
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>WEB-INF/applicationContext.xml</param-value>
          </init-param>
         <load-on-startup>1</load-on-startup>
      </servlet>
     <servlet-mapping>

           <param-value>60000</param-value> 
       </context-param> 
  <!-- 错误跳转页面 -->
  <error-page><!-- 当系统出现404错误时，跳转页面 -->
      <error-code>404</error-code>
      <location>/nopage.html</location>

  <error-page><!-- 当系统出现异常错误是，跳转页面error -->
       <exception-type>java.lang.NullPointerException</exception-type>

  </error-page>
 </web-app>

2. controller.class

@Controller
@RequestMapping("/dada")
public class NewsController {
@Resource
private Newsinter newsinter;
@RequestMapping("/aboutus.html")
  public ModelAndView getNews(){ 

ModelAndView model=new ModelAndView();
model.setViewName("index");
return model;

}
}

3. applicationContext.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:context="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-3.1.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd
                         http://www.springframework.org/schema/mvc
                         http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<mvc:annotation-driven/>

<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
    <context:component-scan base-package="com.reading.controller"/>
    
     <!-- 设置freeMarker的配置文件路径 -->
    <bean id="freemarkerConfiguration"
          class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    </bean> 

<!--视图解析转jsp-->

    <!--设置从控制类过来的页面自动加上后缀;使用 viewResolver 通过加前缀 /WEB-INF/jsp/ 以及加后缀 .jsp 来解析该名称。
    这将允许运行时环境在应用程序目录中查找该文件，它只能解析.jsp-->
   <!--    <bean id = "viewResolver"
         class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name = "prefix" value = "/WEB-INF/view/"/>
       <property name = "suffix" value = ".jsp"/>
    </bean> -->  

<！--以下都是关键：-->
    <!-- 视图解析转html -->
       <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> 
    
     <bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
        <property name="exposeRequestAttributes" value="true" />
        <property name="exposeSessionAttributes" value="true" />
        <property name="viewClass">
            <value>org.springframework.web.servlet.view.freemarker.FreeMarkerView</value>
        </property>
        <property name="cache"><value>true</value></property>
        <property name="suffix"><value>.html</value></property>
        <property name="contentType">
            <value>text/html; charset=UTF-8</value>
        </property>
    </bean>
</beans>

4.然后最后一步访问成功了！
