主要使用到的jar 文件：spring mvc +freemarker.jar

第一步：spring mvc 集成 freemarker

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		
    		<property name="prefix" value="/backstage/jsp/" />
    		<property name="suffix" value=".jsp" />
    		<property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/>
    		 <property name="order" value="1"/>
    	</bean>
    	
    	  
        <bean id="viewResolverFtl" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/>
            <property name="contentType" value="text/html; charset=UTF-8"/>
            <property name="exposeRequestAttributes" value="true" />
            <property name="exposeSessionAttributes" value="true" />
            <property name="exposeSpringMacroHelpers" value="true" />
            <property name="cache" value="true" />
            <property name="suffix" value=".ftl" />
            <property name="order" value="0"/>
        </bean>
        
          
        <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
            <property name="templateLoaderPath" value="/backstage/jsp/"/>
            <property name="freemarkerVariables">
                <map>
                    <entry key="xml_escape" value-ref="fmXmlEscape" />
                </map>
            </property>
            <property name="defaultEncoding" value="UTF-8"/>
            <property name="freemarkerSettings">
                <props>
                    <prop key="template_update_delay">3600</prop>
                    <prop key="locale">zh_CN</prop>
                    <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
                    <prop key="date_format">yyyy-MM-dd</prop>
                    <prop key="number_format">#.##</prop>
                </props>
            </property>
        </bean>
    
        <bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/>

【重点： 在JSP和Freemarker的配置项中都有一个order property，上面例子是把freemarker的order设置为0，jsp为1。 意思是找view时，先找ftl文件，再找jsp文件做为视图。】

第二步：controller代码

package com.wlsq.controller;
    
    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
    @RequestMapping(value="/ftl")
    public class FreemarkerTest {
    	 @RequestMapping(value="/index",method=RequestMethod.GET)
    	    public ModelAndView index() {
    	        ModelAndView view = new ModelAndView("TestFreemarker/index");
    	        view.addObject("message", "Say hi for Freemarker.");
    	        return view;
    	    }
    
    }

第三步：TestFreemarker/index.ftl

<Html>
        <head>
            <title>${message}</title>
        </head>
        <body>
            <b>${message}</b>
        <body>
    </html>
