/**
 * CXF中的契约优先方式开发及隐式声明头信息
 * -----------------------------------------------------------------------------------------------------
 * 开发流程
 * 1)创建并编写\\src\\META-INF\\calculator.xsd和myCalculator.wsdl文件
 * 2)根据wsdl生成服务端代码(wsdl2java -d D:/Download/ -frontend jaxws21 -keep -verbose myCalculator.wsdl)
 *   它会生成很多的代码,而作为服务端,只需保留SEI即可............如果是客户端,就不能删了
 *   然后把SEI中的@XmlSeeAlso({ObjectFactory.class})和className="....."两处删除
 * 3)编写实现类
 *   在实现类上指定@WebService(serviceName="", wsdlLocation="", endpointInterface="", targetNamespace="")
 * 4)发布服务
 *   发布时的address可任意指定,不要求一定要与myCalculator.wsdl中的<soap:address location=""/>相同
 *   但发布后在浏览器中查看wsdl时会发现,其<soap:address location=""/>值始终与发布时指定的address相同
