Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
At the multi-language system that has same business processing logic, be version, the code equivalent risk avoiding being caused because of the overlapping development of implementation language difference, the embodiment of the invention provides a kind of brand-new solution.With reference to Fig. 3, be that the present invention realizes principle schematic.The principle that the present invention realizes is: by defining an intermediate language that is with the definition of complete interface, event definition and processing logic, and by finishing lexical analysis and grammatical analysis work (being compilation process) to middle language text, final character ACE language and figure JSP (the Java Server Pages of generating, be a kind of dynamic web page technique standard) or JS (JavaScript) two cover code files, realize the unitized overall development work of multilanguage program.
With reference to Fig. 4, be the method flow diagram that the described multi-language system of the embodiment of the invention realizes unitized overall development.To be that example describes below with the application system of bank outlets' front end.
Step 401, abstract and standard turns to intermediate language with the public part of various language.
In order to realize the unitized overall development of multilanguage program, the difference of shielding multi-language system exploitation need extract the public part of various language, represents with a kind of intermediate language.Like this,, convert various language codes then to, just can realize unitized overall development by writing intermediate language code.Because various language codes have identical business processing logic, it is the same writing thinking, and different is the expression way of code, so can be abstracted into a kind of general expression way, i.e. intermediate language to the public part of various language performances.Wherein, the public part of described various language mainly comprises two parts: public control resource (territory, tabulation, form, menu, screen etc.) and public accident driving method (screen event, territory incident, form incident etc.), when utilizing various language compilation code, all need to realize the definition and the processing of described public part.
Intermediate language is a kind of transaction development language of front end system, mainly comprises two parts content: a part is the interface definition, is used to describe described public control resource; Another part is event definition and logical process, is used to describe described public accident driving method.Intermediate language uses resource file to describe the interface of man-machine interaction, mainly comprises: territory, tabulation, form, menu, screen, as shown in the table respectively:
