JAXB 面试题与答案

Question: What are the goals of JAXB?

• Easy to use require minimal XML knowledge, don't require SAX/DOM knowledge.
• Customizable can customize mapping of XML to Java.
• Portable can change JAXB implementation without changing source code.
• Deliver soon, deliver core functionality ASAP.
• Follow standard design and naming conventions in generated Java.
• Match schema, easy to identify generated Java components that correspond to schema features.
• Hide plumbing encapsulate implementation of unmarshalling, marshalling and validation.
• Validation, on demand validate objects without requiring marshalling.
• Preserve object equivalence (round tripping), marshalling objects to XML and unmarshalling back to objects results in equivalent objects.
