springMVC返回HTML视图配置

首先在web.xml中进行相关配置

<servlet>
            <servlet-name>springMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
            <async-supported>true</async-supported>
        </servlet>
        <servlet-mapping>
            <servlet-name>springMVC</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/applicationContext.xml</param-value>
        </context-param>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

然后在applicationContext.xml中配置渲染器

<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
            <property name="templateLoaderPath" value="/WEB-INF/pages/" />
            <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>

最后再到springMVC的配置文件中配置，我这里该文件名称为dispatcher-servlet.xml

<bean id="freemarkerConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean"></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>

html视图渲染的核心就是freemarker！！！

加说一段，如果项目中既有html也有jsp，我这里是配置两种视图解析器：

![70][]

order属性进行设置 系统首先按解析器的order值进行查找 首先使用FreeMarkerViewResolver解析器调用canHandle方法，判断当前解析器对视图是否能够解析。如不能解析在依次调用其他的。

注意上面两个解析器配置必须把freemarker解析器的顺序放在前面，即配置为：<property name="order" value="0"/>
