[java][webservice] structs2 x eclipse x window8

前言1:java , tomcat設定 可以參考.前面幾篇

前言2:struts2 架構

ref : 官方說明文件

Struts2 的 Action 能夠相容 POJO

講白話一點就是什麼都不用繼承的 class 就能當 Action 用.
POJO類別簡單來說，就是單純的
Java類別，不帶有其他框架 API 呼叫，開發者可以以簡單不複雜的方式(不必實
作一些繁複的介面或繼承)來開發商業邏輯，減少與其他元件的耦合性.
action:Each URL is mapped to a specific action.

專案結構:

1. download struts2 lib

2. create dynamic web project

3. put structs2 lib to your web-inf\lib

4. create model =>HelloWorldAction.java  

Struts 2 framework will create an object of HelloWorldAction.java,

and call execute method.

package com.tutorialspoint.struts2;

public class HelloWorldAction{
   private String name;
   private String age;

 public String getAge() {
  return age;
 }

 public void setAge(String age) {
  this.age = age;
 }

 public String execute() throws Exception {
  System.out.println(name+age);
  return "success2";
 }

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }
}

5. create view    under webContent=>HelloWorld.jsp

<s:property value="name"/> 會呼叫 HelloWorldAction.java的getname()

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
</head>
<body>
   Hello World,<s:property value="name">
   

   age ,<s:property value="age">
</body>
</html>

6.create main page   under webContent => index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
   pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
   
<html>
<head>

</head>
<body>
   

Hello World From Struts2

      Please enter your name and age

      
      
      
   

Hello World From Struts2 Extend

      Please enter your name and age

      
      
      
   

Hello World From Struts2 Map 

      Please enter your name 

      
      
      
   
</body>
</html>

action = hello . mapping to HelloWorldAction class , use struts.xml to setting

7.create struts.xml under src/

   
     
      
            /HelloWorld.jsp
      
      
       
            /HelloWorld.jsp
            /AccessDenied.jsp
         
        
            /HelloWorldMap.jsp
            /AccessDenied.jsp
         
      
   
   

The only requirement for actions in Struts2 is that there must be one no-argument method that returns either a String or Result object and must be a POJO. If the no-argument method is not specified, the default behavior is to use the execute() method.

8.create web.xml  under webContent/web-inf

   
   Struts 2
   
      index.jsp
   
   
      struts2
      
         org.apache.struts2.dispatcher.FilterDispatcher
      
   

   
      struts2
      /*
 
 
   

9.enable detail log (先跳過)

10. [test] run your project 

11. struts.properties file (if need, this will have default)

### When set to true, Struts will act much more friendly for developers
struts.devMode = true

### Enables reloading of internationalization files
struts.i18n.reload = true

### Enables reloading of XML configuration files
struts.configuration.xml.reload = true

### Sets the port that the server is run on
struts.url.http.port = 8080

      create under web-inf/classes

Create Multiple Actions

_1.  create HelloWorldActionExtendActionSupport.java

package com.tutorialspoint.struts2;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorldActionExtendActionSupport extends ActionSupport{
   private String name;

   public String execute() throws Exception {
      if ("SECRET".equals(name))
      {
         return SUCCESS;
      }else{
         return ERROR;  
      }
   }
   
   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }
}

_2.  add content to struts.xml

   
     
      
            /HelloWorld.jsp
      
      
       
            /HelloWorld.jsp
            /AccessDenied.jsp
         
        
            /HelloWorldMap.jsp
            /AccessDenied.jsp
         
      
   
   

ValueStack/OGNL Example

The Object-Graph Navigation Language (OGNL) is a powerful expression language that is used to reference and manipulate data on the ValueStack. OGNL also helps in data transfer and type conversion.

=1.  create HelloWorldActionExtendActionMap.java

package com.tutorialspoint.struts2;

import java.util.*; 

import com.opensymphony.xwork2.util.ValueStack;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class HelloWorldActionMap extends ActionSupport{
   private String name;

   public String execute() throws Exception {
      ValueStack stack = ActionContext.getContext().getValueStack();
      Map context = new HashMap();

      context.put("key1", this.name); 
      context.put("key2", this.name);
      stack.push(context);

      System.out.println("Size of the valueStack: " + stack.size());
      return "success";
   }  

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }
}

=2. add content to struts.xml(同上)
=3. add HolloWorldMap.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>

</head>
<body>
   Entered value : <s:property value="name">

   Value of key 1 : <s:property value="key1">

   Value of key 2 : <s:property value="key2"> 


</body>
</html>

[java] delete non-empty folder / (subfolders). | 刪除整個文件(包含裡面的文件)

以下提供兩種刪整個非空資料夾的方法，
但實際翻了一下

FileUtils.deleteDirectory(File folder);

的source code 後發現兩種是一樣的=.=...

另外:

FileUtils.waitFor(file, 5);

是個好用的東西，他實際上就是在時間內
一直呼叫file.exist(),並且程式會停在這邊，
直到時間到.
這樣就不用自己寫監控檔案下載完了沒XD

package test_fb_api;
import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;

//http://commons.apache.org/proper/commons-io/apidocs/org/apache/commons/io/FileUtils.html#deleteDirectory%28java.io.File%29

public class testDeleteNonEmptyFolder {

 public static int tag = 0;

 public static void main(String[] args) {

  String path = "F:/opt_test/";
  String path2 = "F:/opt_test2/";

  File file = new File(path);

  System.out.println(FileUtils.waitFor(file, 5));

  System.out.println("deleteMethodB:");
  System.out.println("exists before delete : " + file.exists());
  deleteMethodB(file);
  System.out.println("exists after  delete : " + file.exists());

  System.out.println("===========================");
  System.out.println("deleteMethodA:");
  File file2 = new File(path2);
  // set tag = 0 , because "deleteMethodA" is recursive.
  // so you don't know where go false, or is still folder
  tag = 0;
  System.out.println("exists before delete : " + file2.exists());
  deleteMethodA(file2);
  if (tag == 0) {
   System.out.println("deleteMethodA: delete success");
  } else {
   System.out.println("deleteMethodA: have subFolder: " + tag);
  }
  System.out.println("exists after  delete : " + file2.exists());
 }

 public static void deleteMethodB(File folder) {
  try {
   FileUtils.deleteDirectory(folder);
  } catch (IOException e) {
   // TODO Auto-generated catch block
   System.out.println(e.getMessage());
  }
 }

 public static void deleteMethodA(File folder) {
  // check if folder file is a real folder
  if (folder.isDirectory()) {
   File[] list = folder.listFiles();
   if (list != null) {
    for (int i = 0; i < list.length; i++) {
     File tmpF = list[i];
     if (tmpF.isDirectory()) {
      deleteMethodA(tmpF);
     }
     if (!tmpF.delete()) {
      tag++;

[java] better way to remove object in arraylist, 從arraylist 拿掉不需要的

如果想在一個迴圈裡面拿掉不須要的item，有兩個可以呼叫，
1.remove(int index)
2.remove(object o)

package test_fb_api;

import java.util.ArrayList;
import java.util.HashMap;



public class testArrayListRemove {

	public static void main(String[] args) {
		
		ArrayList bookShelfData_ReName = new ArrayList();
		bookShelfData_ReName.add("1");
		bookShelfData_ReName.add("2");
		bookShelfData_ReName.add("3");
		bookShelfData_ReName.add("5");
		bookShelfData_ReName.add("2");
		
		System.out.println("remove(int index)");
		for(int i = 0 ; i< bookShelfData_ReName.size() ; i++)
		{	
			System.out.println("===============");
			System.out.println("before:"+bookShelfData_ReName);
			if(bookShelfData_ReName.get(i).equals("2"))
			{
				bookShelfData_ReName.remove(i);
			}
			System.out.println("after:"+bookShelfData_ReName);
			
		}
		System.out.println("****************************");
		
		ArrayList bookShelfData_ReName2 = new ArrayList();
		bookShelfData_ReName2.add("1");
		bookShelfData_ReName2.add("2");
		bookShelfData_ReName2.add("3");
		bookShelfData_ReName2.add("5");
		bookShelfData_ReName2.add("2");
		
		System.out.println("remove(object)");
		System.out.println("===============");
		ArrayList forRemove = new ArrayList();
		for(int i = 0 ; i< bookShelfData_ReName.size() ; i++)
		{	
			if(bookShelfData_ReName.get(i).equals("2"))
			{
				forRemove.add(bookShelfData_ReName.get(i));
			}
			
		}
		for(int i = 0 ; i< forRemove.size() ; i++)
		{
			bookShelfData_ReName.remove(forRemove.get(i));
		}
		System.out.println("after:"+bookShelfData_ReName);
		
		//still O(n)
	}

}

結果:
