一.利用BaseController 方式处理

定义BaseController 如下：

package com.ly.jxc.controller;

import org.springframework.stereotype.Controller;

import freemarker.ext.beans.BeansWrapper;
import freemarker.template.TemplateHashModel;
import freemarker.template.TemplateModelException;

@Controller
public class BaseController {
    private final static BeansWrapper wrapper = BeansWrapper
            .getDefaultInstance();
    private final static TemplateHashModel staticModels = wrapper
            .getStaticModels();

    protected static TemplateHashModel useStaticPacker(String packname) {
        TemplateHashModel fileStatics = null;
        try {
            fileStatics = (TemplateHashModel) staticModels.get(packname);
        } catch (TemplateModelException e) {
            e.printStackTrace();
        }
        return fileStatics;
    };

}

其他controller 继承 BaseController ,需要返回静态类时候 如下：

//register 静态访问
 map.put("rule",useStaticPacker("com.ly.jxc.RuleUtils"));

页面使用：

    <#if user.canRead(RuleUtils.BUY_ORDER) || user.canRead(RuleUtils.BUY_LOG) >
.....
</#if>

二 使用配置方式

定义FreemarkerStaticModels.java  如下：

package com.ly.jxc.util;

import java.util.HashMap;
import java.util.Properties;
import java.util.Set;

import freemarker.ext.beans.BeansWrapper;
import freemarker.template.TemplateHashModel;
/**
 *   处理freeMarker  访问静态类静态方法
 * @author Administrator
 *
 */
public class FreemarkerStaticModels extends HashMap<Object, Object>{

    /**
     *
     */
    private static final long serialVersionUID = 1L;
    private static FreemarkerStaticModels FREEMARKER_STATIC_MODELS;
    private Properties staticModels;

    private FreemarkerStaticModels(){

    }

    public static FreemarkerStaticModels getInstance(){
        if(FREEMARKER_STATIC_MODELS==null){
            FREEMARKER_STATIC_MODELS=new FreemarkerStaticModels();
        }
        return FREEMARKER_STATIC_MODELS;
    }

    public Properties getStaticModels() {
        return staticModels;
    }

    public void setStaticModels(Properties staticModels) {
        if(this.staticModels==null&&staticModels!=null){
            this.staticModels = staticModels;
            Set<String> keys=this.staticModels.stringPropertyNames();
            for (String key : keys) {
                FREEMARKER_STATIC_MODELS.put(key, useStaticPackage(this.staticModels.getProperty(key)));
            }
        }
    }

    public static TemplateHashModel useStaticPackage(String packageName){
        try
        {
          BeansWrapper wrapper = BeansWrapper.getDefaultInstance();
          TemplateHashModel staticModels = wrapper.getStaticModels();
          TemplateHashModel fileStatics = (TemplateHashModel) staticModels.get(packageName);
          return fileStatics;
        }
        catch (Exception e)
        {
           e.printStackTrace();
        }
        return null;
    }

}

定义staticClass.properties

RuleUtils=com.ly.jxc.util.RuleUtils

在springmvc.xml 配置文件中

<!-- freemarker 静态类的配置位置 -->
    <bean id="freemarkerStatic"
        class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:staticClass.properties" />
    </bean>
    <!-- freemarker 静态类的解析配置-->
    <bean id="freemarkerStaticModels"
        class="com.ly.jxc.util.FreemarkerStaticModels" factory-method="getInstance">
        <property name="staticModels" ref="freemarkerStatic"/>
    </bean>

<!-- 配置freeMarker视图解析器 -->

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

        <property name="viewClass"
            value="com.ly.jxc.util.FreeMarkerPath" />

        <!-- <property name="viewNames" value="*.ftl"/> -->

        <property name="contentType" value="text/html; charset=utf-8" />
        <property name="allowSessionOverride" value="true" />
        <property name="cache" value="true" />

        <property name="prefix" value="" />

        <property name="suffix" value=".html" />

        <property name="order" value="0" />
        <!-- freemarker 静态类配置 -->
         <property name="attributesMap" ref="freemarkerStaticModels"/>

    </bean>

页面使用 同上。

最后说下两种的选择： 第一种实用于哪里用到哪里调用，第二种是直接返回所有到页面。
