The invention discloses a multilingual cloud compiling method and system for achieving dynamic interception and extension of system functions. According to business requirements, a method needing to be extended is marked with an interception label; before an item is compiled, target interception labels corresponding to the system functions needing to be extended are screened; then, for the method marked with the target interception labels, during local compiling, a compiling interception device code is added at the corresponding position according to the target interception labels, and then according to the interception device code, a corresponding business logic interception code is compiled through cloud compiling and runs. By means of the multilingual cloud compiling method and system, the business logic interception code can be dynamically and remotely added in real time through the interception labels according to the business requirements, and therefore during system running, the business logic interception code is compiled through cloud compiling and then is directly introduced and runs, previous codes are not influenced, a dynamic scrip engine system is achieved, then, dynamic interception and extension of the system functions are achieved, and flexibility, openess, maintainability and scalability of extension of the system functions are improved.
