In this paper, according to the characteristics of CML2 system,a kind of system configuration design method is put forward based on XSLT technology. It is mainly based on the model driven architecture design patterns, to transfer the system configuration development core to the model, get the final system configuration through the conversion between model and code generation technology, semantic constraint model using XSD .Through the XSL language to convert the target file,It is ready to use software configuration method of software component of the "plug and play"in different platform, easy to maintain and operate.
