    Hi

    Anyone like to offer an example that uses the org.apache.commons.digester to create objects with a non empty constructor. Nothing too complicated - an object with a String in the Constructor will suffice.

    前段时间项目中需要根据xml文件创建java对象,而apache commons-digester是首选.
    一直想把它写下来,可是总有点懒 这次介绍一下digester的常用法,其他更高级的使用方法请参阅digester doc(由于比较忙,下次有时间写一篇关于cglib的常用法,呵呵)

    一.序
      Digester是apache的一个组件 apache commons-digester.jar,通过它可以很方便的从xml文件生成java对象.你不用再象以前通过jdom或者Xerces去读取一个 document对象.(jdom和Xerces仍然有它们的用武之地及强大之处,在其它应用里你也少不了它们)
    我只是用一个例子展示一下如何把xml文件生成一个java object.
    首先你必须把jar加入到你的项目classpath.
    (一)准备:
    1.环境: Eclipse, jdk1.4+
    2.需求说明：学院包含学生和老师，学生可以选修课程，老师有不同的资格认证。
    3.Java Class的定义，简洁起见，略去import内容。
    4.使用Digester生成java对象 必须要定义一个xml文件，此xml文件必须符合digester-rules.dtd的规则。
    5.所有的xml文件必须在classpath路径中，这样可以通过Class.getClassLoader().getInputStream()读取xml文件。

    (二)提要:
      本示例所需的java class 和 xml文件分成四类:
    1.基础xml文件: [academy.xml]: 你将要解析的xml文件.
    2.基础java class: [Academy.java, Teacher.java, Student.java, Cousre.java]: 生成的对象的类定义
    3.digesterRules.xml: [academyRules.xml]: 定义了基础xml文件到基础java class的匹配(映射)关系
    4.Digester class: [DigestXMLJavaAcademy.java]: 根据digesterRules.xml去解析基础xml文件,并生成java 对象

    五.运行结果

    PropertyUtils.describ(Object)用法

    http://philos.iteye.com/blog/176724

    使用org.apache.commons.beanutils.PropertyUtils.describ(Object)生成Map实例，其中包含了源bean中所有可读的属性。下面的代码片段演示了这个特性：


    1. Person author =  new  Person();  
    2. author.setName("Timothy M. O'Brien" );  
    3.           
    4. Book book = new  Book();  
    5. book.setName("Jakarta Commons Cookbook" );  
    6. book.setAuthor(author);  
    7.       
    8. // 取得book中的所有可读属性,返回到map中   
    9. Map bookMap = PropertyUtils.describe(book);  
    10. // Book类中包含一个Author类型的属性   
    11. // 取bookMap中的author bean,并将其所有可读属性返回到authorMap中   
    12. Map authorMap = PropertyUtils.describe(bookMap.get("author" ));  
    13.       
    14. // 输出   
    15. // Book Name: Jakarta Commons Cookbook   
    16. // Author Name: Timothy M. O'Brien   
    17. System.out.println("Book Name: "  + bookMap.get( "name" ));  
    18. System.out.println("Author Name: "  + authorMap.get( "name" ));   
    Person author = new Person();
author.setName("Timothy M. O'Brien");
        
Book book = new Book();
book.setName("Jakarta Commons Cookbook");
book.setAuthor(author);
    
// 取得book中的所有可读属性,返回到map中
Map bookMap = PropertyUtils.describe(book);
// Book类中包含一个Author类型的属性
// 取bookMap中的author bean,并将其所有可读属性返回到authorMap中
Map authorMap = PropertyUtils.describe(bookMap.get("author"));
    
// 输出
// Book Name: Jakarta Commons Cookbook
// Author Name: Timothy M. O'Brien
System.out.println("Book Name: " + bookMap.get("name"));
System.out.println("Author Name: " + authorMap.get("name"));

    在上面的例子中假如Book类中还有个Integer型的page属性，代表书籍页数，在没设置的情况下，将返回null，如果page属性为int型，则将返回0。

    FileUpload 1.2.1 - 18 January 2008

    • Download the binary and source distributions from a mirror site here

    DWR + FileUpload 多文件上传实例

    http://www.iteye.com/topic/247420

    功能： 文件上传

    特点： 动态显示进度， 百分比， 文件名， 文件长度， 上传速度... 剩下的自己看吧

    主要技术： DWR， Apache commons FileUpload

    原理： FileUpload实现上传功能， UploadListener 监听上传进度， DWR push (Reverse Ajax) 进度信息并更新页面， 实现无刷新多文件上传

    运行环境： Tomcat 6， WAS 6 测试通过

    WAR 包下载 见附件

    顺便截个图：
