为etmvc添加Helpers

----------------------------------------------------------------------------------------------------

后来发现一个更为简便的方法

直接  super.getRequest().setAttribute("request", request);

汗死 脑袋被拍砖了

----------------------------------------------------------------------------------------------------

 

 

在etmvc+freemarker的环境下若想在ftl中得到当前页面的URL还是比较繁琐的（貌似使用etmvc后不能在ftl中使用request对象了）为此我只好些个Helpers了，

先建立个实体如下。

 

/* ***********************************************
 * author :  Anyhome
 * email  :  [e-mail] 
 * function: 
 * @date 2009-12-14
 * history:  created by Anyhome
 * ***********************************************/
 
/**
 * 具体还可以自己再增减
 */
package org.anyhome.models;

import java.util.List;

/**
 * @author Ayhome
 *
 */
public class MyHelpers {
	private String Url;
	private String HostName;
	private String Controller;
	private String Action;
	private String Method;
	private String ContextPath;
	private String Uri;
	private List<String> Permission;
	public void setUrl(String url) {
		Url = url;
	}
	public String getUrl() {
		return Url;
	}
	public void setHostName(String hostName) {
		HostName = hostName;
	}
	public String getHostName() {
		return HostName;
	}
	public void setController(String controller) {
		Controller = controller;
	}
	public String getController() {
		return Controller;
	}
	public void setAction(String action) {
		Action = action;
	}
	public String getAction() {
		return Action;
	}
	public void setMethod(String method) {
		Method = method;
	}
	public String getMethod() {
		return Method;
	}
	public void setContextPath(String contextPath) {
		ContextPath = contextPath;
	}
	public String getContextPath() {
		return ContextPath;
	}
	public void setUri(String uri) {
		Uri = uri;
	}
	public String getUri() {
		return Uri;
	}
	public void setPermission(List<String> permission) {
		Permission = permission;
	}
	public List<String> getPermission() {
		return Permission;
	}
}

 

 然后前置过滤器如下

 

	protected boolean InitPages() throws ActiveRecordException{
		MyHelpers Helpers = new MyHelpers();
		Helpers.setAction(super.getActionName());
		Helpers.setController(super.getControllerName());
		Helpers.setUrl(super.request.getRequestURL().toString());
		Helpers.setUri(super.request.getRequestURI());
		Helpers.setContextPath(super.request.getContextPath());
		//---		
		String ss = super.getControllerName().toLowerCase();
		if (ss!="desktop"){
			if (MyUserTicket!=null){
				List<String> lst = new ArrayList<String>();
				if (MyUserTicket.getU_Type()!=0){	
					lst = Permission.CheckAndPermiss(MyUserTicket.getUserID(),super.getControllerName());					
				}else{
					for (String s:Permission.PopedomType().keySet()){
						lst.add(s);				
					}
				}
				Helpers.setPermission(lst);
			}
		}
		super.getRequest().setAttribute("Helpers", Helpers);
		
		return true;
	}	
	

 

过滤器调用

 

 

 @BeforeFilter(execute="Auth"),

 FTL中的调用如 

 

${Helpers.controller}
