import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; /** * 接口 * * @author leftso * */ @WebService(name = "CommonService", // 暴露服务名称 targetNamespace = "http://webservice.leftso.com/"// 命名空间,一般是接口的包名倒序 ) public interface CommonService { @WebMethod @WebResult(name = "String", targetNamespace = "") public String sayHello(@WebParam(name = "userName") String name);
