配置文件的封装：

     
             
                  
       
        /login.jsp 
                   
       
        /index.jsp 
               
                      
                  
       
        /index.jsp 
               
      
     

如果对这个配置文件进行封装，采用由里到外的思想，层层封装。

result---》action----》package

对result封装

package cn.lyjs.framework.bean;public class Result {    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getType() {        return type;    }    public void setType(String type) {        this.type = type;    }    public String getPage() {        return page;    }    public void setPage(String page) {        this.page = page;    }    //跳转的结果标记    private String name;    //跳转的类型  转发  重定向    private String type;    //跳转的页面    private String page;}

对Action的封装

package cn.lyjs.framework.bean;import java.util.Map;/** * 封装action节点 *         
                 
       
              
      * @author Lavender * */public class ActionMapping {    //请求路径名称    private String className;    //处理action类的全名    private String classPath;    //处理方法    private String method;    //结果视图集合    private Map
     
       results;    public String getClassName() {        return className;    }    public void setClassName(String className) {        this.className = className;    }    public String getClassPath() {        return classPath;    }    public void setClassPath(String classPath) {        this.classPath = classPath;    }    public String getMethod() {        return method;    }    public void setMethod(String method) {        this.method = method;    }    public Map
      
        getResults() {        return results;    }    public void setResults(Map
       
         results) {        this.results = results;    }}
       
      
     

所有Action加入集合

package cn.lyjs.framework.bean;import java.io.InputStream;import java.util.HashMap;import java.util.Iterator;import java.util.List;import java.util.Map;import org.dom4j.Document;import org.dom4j.Element;import org.dom4j.io.SAXReader;public class ActionMappingManager {        private Map
     
       allActions;        public ActionMappingManager(){        allActions = new HashMap
      
       ();        // 初始化        this.init();    }        public ActionMapping getActionMapping(String actionName){        if(actionName==null){            throw new RuntimeException("传入参数有误，请查看struts.xml配置的路径。");        }        ActionMapping actionMapping=allActions.get(actionName);        if(actionMapping==null){            throw new RuntimeException("路径在struts.xml中找不到，请检查");        }        return actionMapping;    }        private void init(){        try {            SAXReader reader=new SAXReader();            InputStream inputStream=this.getClass().getResourceAsStream("/mystruts.xml");            Document docment= reader.read(inputStream);            Element root=docment.getRootElement();            Element packageList=root.element("package");        //    for(Element list: packageList){
                     List
       
         listAction=packageList.elements("action");                for(Element ele_action:listAction){                    ActionMapping actionMapping=new ActionMapping();                    actionMapping.setClassName(ele_action.attributeValue("name"));                    actionMapping.setClassPath(ele_action.attributeValue("class"));                    actionMapping.setMethod(ele_action.attributeValue("method"));                    Map
        
          results=new HashMap
         
          ();                    Iterator i=ele_action.elementIterator("result");                    while(i.hasNext()){                        Element ele_result=(Element) i.next();                        Result result=new Result();                        result.setName(ele_result.attributeValue("name"));                        result.setType(ele_result.attributeValue("type"));                        result.setPage(ele_result.getTextTrim());                        results.put(result.getName(), result);                    }                    actionMapping.setResults(results);                    allActions.put(actionMapping.getClassName(), actionMapping);                }                                        //    }        } catch (Exception e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
