如何通过Java生成xml文件？

Question

I have to generate huge and quite complex xml files by Java. I have to fetch the data from a Oracle database. What I really don't know is a proper and reliable way to this? I could of course create a String and concatenate all the tags, attributes and data but it doesn't feel right. I guess this is a quite common task and there are many established ways to this by Java. My question is what is the best way to this? What is your suggestion? Thank you for any clues...

Answer 1

You could use JAXB for building XML out of structured objects that are a result of querying your data store.

If your object hierarchy is not complex, you can use Oracle's capability to generate results in XML .

Answer 2

There are several options for object to xml transformation.

• jaxb
• saxparser
• dom parser

I would personally suggest JAXB for easy of use and saxparser for performance centric application.

Answer 3

您可以使用JAXP（用于XML解析的Java API）创建XML结构。它具有您想要的所有功能。
