The Design And Implementation Of Web Services Synthesis Tool Based On AOP

Service-Oriented Computing(SOC) is one of the research focuses in the current software engineering and software industry. It is a new computing paradigm that utilizes web services as the basic constructs to support the development of rapid, lowcost and easy composition of distributed applications. But traditional software development technology can not separate the business logic from other behavior of ancillary business logic,whose software design ideas and modular mechanisms often make business logic functions and non-business behavior intertwined, resulting in the software systems presence of business logic not clear, code tangling,code redundancy and waste, the tight coupling between modules,hard to expand and inflexible etc.The aspect-oriented software development method can effectively contribute to solving the above problems.This paper first outlined the research background of this topic and the research significance are given,and lists the domestic and overseas' research status of AOP methods and Web service technology.Then by deeply analyzing the related theory technique and its advantage,this paper systematically implemented the design scheme of Web services synthesis tool based on AOP.Finally the example analysis is given to verify its validity and practicality.AOP and Web service are thoroughly analyzed combined with the related theory of technology and advantages on the basis of systemic implements Web services based on AOP synthesis tool design,Efficient algorithm for web services adapter automatic generation and adapterbased web services interactive correctness verification is the main research content in the current adaptation technology.The main work includes the following three aspects:This paper presents a Web Services composing algorithm based on the formal modeling technique—CFN.On the achievement level, it uses Aspect J to design and build a Web Service composing tool based on AOP. Meanwhile, the Web Services composing tool can be integrated effectively with the Web Services modeling tool and the Web Services adaptation tool.Finally we verify the validity of the Web Service composing tool as well as the correctness of the Web Service adapter by using the prototype tool to compose some web service instances.
