第二步在指定的HTMLFilter类中配置

import java.io.IOException;
    import java.util.Enumeration;
    import java.util.HashMap;
    import java.util.Map;
    import javax.servlet.Filter;
    import javax.servlet.FilterChain;
    import javax.servlet.FilterConfig;
    import javax.servlet.ServletException;
    import javax.servlet.ServletRequest;
    import javax.servlet.ServletResponse;
    import org.beetl.core.GroupTemplate;
    import org.beetl.ext.jfinal.BeetlRenderFactory;
    import org.beetl.ext.web.SimpleCrossFilter;
    
    /**
     *
     * @ClassNmae：HTMLFilter
     * @author zlx-雄雄
     * @date    2017-8-16 11:42:41
     * 
     */
    public class HTMLFilter extends SimpleCrossFilter implements Filter {
    
        @Override
        public void init(FilterConfig arg0) throws ServletException {
        }
    
        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException,ServletException {
            response.setContentType("text/html;charset=UTF-8");
            
            response.setCharacterEncoding("UTF-8");
            
            request.setCharacterEncoding("UTF-8");
            
            Enumeration<String> names = request.getParameterNames();
            
            Map<String, Object> param = new HashMap<>();
            
            while(names.hasMoreElements()){
                
                String key = names.nextElement();
                
                param.put(key, request.getParameter(key));
                
            }
            
            request.setAttribute("param", param);
            
            super.doFilter(request, response, chain);
        }
    
        @Override
        protected GroupTemplate getGroupTemplate() {
            
            return BeetlRenderFactory.groupTemplate;
            
        }
    }

可以在jfinal配置类的configConstant(Constants me)【系统启动配置常量初始化】方法中设置共享变量

public static JPushClient jpushClient;
        public static GroupTemplate gt;
    
        /**
         * 系统启动配置常量初始化
         * @param me
         */
        @Override
        public void configConstant(Constants me) {
            me.setEncoding("UTF-8");
            PropKit.use("config.txt");// 加载少量必要配置，随后可用getProperty(...)获取值
            me.setDevMode(PropKit.getBoolean("devMode", Boolean.TRUE));
            me.setError404View("/error/error404.html");
            me.setError500View("/error/error500.html");
            me.setJspViewExtension("/error/exceptionPage.jsp");
            me.setBaseUploadPath(PathKit.getWebRootPath() + "\\tempupload\\");
            
            me.setMainRenderFactory(new BeetlRenderFactory());
            gt = BeetlRenderFactory.groupTemplate;//根据gt可以添加扩展函数，格式化函数，共享变量等
            Map<String, Object> shard = new HashMap<>();//共享变量
            shard.put("path", JFinal.me().getContextPath());//添加共享变量上下文路径
            String  static_url = PropKit.get("static_url");
            shard.put("static_url",static_url );
            shard.put("image_upload_url", static_url+PropKit.get("image_upload_url"));
            shard.put("upload_url", static_url+PropKit.get("upload_url"));
            shard.put("file_manager_json_url", static_url+PropKit.get("file_manager_json_url"));
            gt.setSharedVars(shard);//设置共享变量
        }
