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;@Controllerpublic 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) >.....

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
     
      {        /**     *      */    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
      
        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
