如何在java中生成XML（在String表示中） [英] How to generate XML (in String representation) in java

问题描述

我已经定义了一个java类，但只需要将这个类的一些字段输出到XML中。返回的类型必须是String。我首先选择了使用StringBuffer的最简单方法。但是，当我尝试处理输出字符串表示时，它失败了。我认为这很可能是因为有些字符在输入中没有在UTF-8中编码。有人能告诉我处理这个问题的最佳方法是什么？谢谢。

I have defined a java class, but only need to output some of the fields of this class into an XML. The returned type must be a String. I first opted for the easiest way using a StringBuffer. However, when I tried to process the output String represenation, it failed. I think it is mostly likely because there are some characters that are not encoded in the UTF-8 in the input. Could someone tell me what is the best way to handle this? Thanks.

推荐答案

给 XStream 一试。

引用：

让我们创建一个Person实例，并在
中填充其字段：

Let's create an instance of Person and populate its fields:

 Person joe = new Person("Joe", "Walnes");
 joe.setPhone(new PhoneNumber(123, "1234-456"));
 joe.setFax(new PhoneNumber(123, "9999-999")); 

现在，将它转换为
XML，所有你我要做的就是对XStream进行
简单调用：

Now, to convert it to XML, all you have to do is make a simple call to XStream:

String xml = xstream.toXML(joe)

生成的XML如下所示：

The resulting XML looks like this:

<person>
  <firstname>Joe</firstname> 
  <lastname>Walnes</lastname>
  <phone>
    <code>123</code>
    <number>1234-456</number>
  </phone>
  <fax>
    <code>123</code>
    <number>9999-999</number>
  </fax> 
  </person> 

就这么简单。看看XML是多么干净。

It's that simple. Look at how clean the XML is.
