自底向上

创建Web服务（自顶向下、自底向上和Web服务客户机）

Creating Web services ( top-down , bottom-up and Web services clients )

Web服务可以通过两种方法来生成：自顶向下的开发和自底向上的开发。

Web services can be created using two approaches : top-down development and bottom-up development .

Bottom-up Web services development approach

自底向上（即从Java实现类入手）

Bottom-up ( that is , start from a Java implementation class )

在自底向上方式中，您先通过创建基本活动来定义流程，然后再将活动添加到sequence中。

In the bottom-up approach , you define the process by creating primitive activities first and then add in the sequence later .

您需要一个自底向上的JavabeanWeb服务，并且应该将您的Java类指定为服务实现

虽然自底向上的方法看起来是那么自然和简单，好像是治疗SOA失败的绝妙处方。

This bottom-up approach is quite natural and easy and is the perfect recipe for a SOA failure .

如果您尝试了本文的所有建议，但仍旧遇到自底向上的Web服务代码生成问题，那么该问题可能是软件的缺陷。

If you try all the suggestions in this article and still encounter bottom-up Web services code generation problems , the problem may be a software defect .

然后，这类可重用流程组件必须经过自顶向下或自底向上的SOA分析流程分析。

Such reusable process components must then necessarily also become subject to the top-down or bottom-up SOA analysis process .

通过不同API来支持多种查询策略（如自底向上、自顶向下），实现对XML树结构数据的查询遍历。

Support various query strategies , such as bottom-up , top-down , through different APIs to traverse the tree-like XML data .

因为我在一个Java类中设计了这个Web服务，所以我将说明如何用自底向上方案创建这个Web服务。

Because I designed this Web service in a Java class , I show you how to create this Web service using the Bottom Up scenario .

如果你自底向上的构建SOA，那么很有可能你最终会得到很多冗余的东西，而毫无架构可言。

If you build SOA Bottom-Up probably you will end with a lot of redundancy and no architecture at all .

该方法之所以称为“自底向上”，是因为它的起点是代码&这些代码被抽象成接口定义，并随后作为实现该接口的Web服务公开。

This approach is called bottom-up because the starting point is code that is being abstracted into an interface definition and subsequently exposed as a Web service implementing that interface .

很多时候，问题是SOA努力过于自底向上了，其中架构师基于现有能力指定服务。

Frequently , the issue is that the SOA effort is excessively bottom-up , where architects specify Services based upon existing capabilities .

这是用于Web服务设计的自底向上体系结构，它主要用于将现有的、基于Java的应用程序转换为Web服务或者用于创建包装这些应用程序的包装器。

This is a bottom-up architecture for web service design and is mainly used to convert existing Java-based applications to web services or to create wrappers around those applications .

分析级别技术（也称为自底向上方法）可用于发现对特定SOA项目有意义的资产。

Analysis level techniques exist , also referred to as bottom-up , to surface the assets that would make sense for a particular SOA project .

例如，您可以使用自底向上流程创建发布在UDDI注册中心内的WSDL。

For example , you can create the WSDL published in a UDDI registry using the bottom-up process .

当增建SOA时，一个自底向上的治理方法会关注于将围绕一些可以快速组装的ESB个体的服务集成起来。

When building out a SOA , a bottom-up governance approach focuses on integrating services around individual ESBs that can be quickly assembled .

如果您在自底向上的Web服务中遇到代码生成问题，那么最有可能的是您的服务类不遵循JAX-RPC。

If you encounter code generation problems in bottom-up Web services , it is most likely that your service class is not JAX-RPC compliant .

在自底向上的方法中，您可以根据Javabean或EnterpriseJava™Beans（EJB）中的现有业务逻辑创建Web服务。

In the bottom-up approach , you create a Web service based on the existing business logic in Java beans or Enterprise Java ™ Beans ( EJBs ) .

值得注意的是，您可以使用自底向上流程生成驱动自顶向下流程的WSDL。

It 's important to note that you can use the bottom-up process to produce the WSDL that drives the top-down process .

构建SOA的最佳方法是将自底向上方法（用于构建解决集成问题的服务）和自顶向下体系结构方法结合使用。

The best approach to building an SOA is to combine a bottom-up approach of building services that solve integration problems with a top-down , architectural approach .
