摘要: Web遗留系统的白盒服务迁移需要侵入原有系统修改代码,因此会产生运行风险。针对该问题,设计并实现一种黑盒包装器环境。通过为遗留系统配置包装器,忽略原系统内部的复杂性,并在不改变系统部署和运行状态的情况下,将遗留的Web应用转化为Web服务。应用结果表明,基于外部包装和规则配置的黑盒方法更具可控性。

Abstract: White-box method for Web legacy system migration need to modify the application source codes and invade the original system, which has great operational risks. To solve the problem, this paper designs a black-box wrapper environment for Web service. Through the wrapper, the complexity of the internal structure of the original system is ignored. The Web application can be migrated into Web services without changing the deployment and operational status of the original system. Application result proves that the method has better controllability.
