编辑 这个问题与Web服务的实现有关(阅读:SOAP) 问题是，应该首先对实现类进行编码，然后从中生成WSDL和XSD模式(最后进行合同)，还是首先编写WSDL和XSD方案并生成实现类(首先进行合同)

EDIT This question is about the implementation of a web service (read: SOAP) The question is whether the implementation classes should be coded first and the WSDL and XSD schema generated from that (contract last) or the WSDL and XSD schema written first and the implementation classes generated (contract first)

推荐答案

合同优先是公认的最佳实践".

Contract-first is the generally accepted 'best practice.'

这使您与服务的生产者和消费者都非常清楚，确切知道需要什么和期望什么.当您开始尝试转换Java类型-> xml类型时，这尤其重要.您还可以在不同的Web服务之间重用架构.

It makes you be very clear with both the producer and consumer of the service exactly what is needed and what is expected. This becomes especially important when you start trying to convert java types -> xml types. You're also able to reuse schemas across different web service.
