O/X Mapper 是什么？ Spring 3.0 的一个新特性是 O/X Mapper。O/X 映射器这个概念并不新鲜，O 代表 Object，X 代表 XML。它的目的是在 Java 对象（几乎总是一个 plain old Java object，或简写为 POJO）和 XML 文档之间来回转换。例如，您可能有一个带有几个属性的简单 bean，且您的业务需要将那个 Java 对象转换为一个 XML 文档。Spring 的 O/X Mapper 能够为您解决那个问题。如果反过来，您需要将一个 XML 文档转换为一个简单 Java bean，Spring 的 O/X Mapper 也能胜任。有一点需要注意：Spring O/X Mapper 只是定义由流行的第三方框架实现的统一的界面。要利用 Spring 的 O/X 功能，您需要一个在 Java 对象和 XML 之间来回转换的实用程序。Castor 就是这样一个流行的第三方工具，本文将使用这个工具。其他这样的工具包括 XMLBeans、Java Architecture for XML Binding (JAXB)、JiBX 和 XStream。编组和解组进行 O/X 映射时，您经常会看到编组（marshalling）和解组（unmarshalling）这两个术语。编组指将 Java bean 转换成 XML

面试被问傻！5亿个数大文件怎么排序？

曾经被问傻的一道面试题分享给你：给你1个文件 bigdata ，大小4663M，5亿个数，文件中的数据随机，如下一行一个整数： 6196302 3557681 6121580 2039345 2095006 1746773 7934312 2016371 7123302 8790171 2966901 ... 7005375 现在要对这个文件进行排序，怎么搞？内部排序先尝试内排，选2种排序方式： 3路快排： private final int cutoff = 8; public <T> void perform(Comparable<T>[] a) { perform(a,0,a.length - 1); } private <T> int median3(Comparable<T>[] a,int x,int y,int z) { if(lessThan(a[x],a[y])) { if(lessThan(a[y],a[z])) { return y; } else if(lessThan(a[x],a[z])) { return z; }else { return x; } }else { if(lessThan(a[z],a[y])){ return y; }else if(lessThan(a[z],a[x])) { return z; }else { return

利用Castor自动生成java文件

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1、编写schema文件，例如：c:\castor\test.xsd。 2、到 http://www.castor.org/ 网站下载castor-xml.jar（本文使用的是0.9.4版本）及编译所要引用的xerces-2.4.0.jar、xercesImpl.jar( http://www.apache.org/ )文件。 3、执行以下脚本生成java文件： java -classpath C:\castor\lib\castor-xml.jar;C:\castor\lib\xerces-2.4.0.jar;C:\castor\lib\xercesImpl.jar;. org.exolab.castor.builder.SourceGenerator -i test.xsd -package com.test.config.vo 4、生成的java文件中自动含包了unmarshal（通过XML文件生成java对象）和marshal（通过java对象生成xml文件）的两个方法。 5、marshal（通过java对象生成xml文件）方法代码如下： public void marshal(java.io.Writer out) throws org.exolab.castor.xml

Generate castor xml from xsd

阅读更多关于 Generate castor xml from xsd

问题 I am currently using the Jaxb for Marshalling/Unmarshalling. However I need to use castor due to "demands" and use castor xml instead of castor java classes. I found castor's SourceGeneratorMain which generates xsd to java classes, but I cannot find anything that generates castor xml from xsd. I would just type it out but the xsd im working is huge with more than 2500 lines and over a hundered parameter various arrays in there. Im sure Im going to screw up something, if I type it out. Has any

What is the difference between Castor XML binding and JAXB binding

阅读更多关于 What is the difference between Castor XML binding and JAXB binding

问题 What is the difference between Castor XML and JAXB binding since both are binding java object to XML and vice versa. Updated : As using Castor I can do this Assume packageA.ClassA and packageB.ClassA have same attributes and class name just that they were located in different package. packageA.ClassA - > XML -> packageB.ClassA By using JAXB if I am doing this Marshall object packageA.ClassA to XML and from XML unmarshall into object packageB.ClassA I got Casting error. 回答1: Please note that

Can Castor handle class generation from multiple XSDs importing from a base XSD?

阅读更多关于 Can Castor handle class generation from multiple XSDs importing from a base XSD?

问题 I have several XSDs that reuse the same entities. For example, both the XSDs for the ProductPurchaseRequest.xsd and ProductQuoteRequest.xsd both have a <product> tag in them to describe the product in question. For this reason I created a Product.xsd file to define the <product> tag and both ProductPurchaseRequest.xsd and ProductQuoteRequest.xsd import the Product.xsd with a `. I would like to use Castor to generate Java classes from theses XSDs, and for both of them to use the same class for
