SmartCode是否可以加入联合主键的识别和代码生成？

目前SmartCode生成的代码，在联合主键的表格中都是简单将第一列当成主键形式生成的，是否可以支持生成一个联合主键列构成的简单封装来作为主键参数？

The issue names SmartCode's generated code but does not identify files, tests, or an entry point. Start by locating the table-schema and primary-key handling in the generator, then determine how composite keys should be represented and generated. Done means composite-primary-key tables are recognized and their generated code uses a single composite-key parameter object rather than only the first column.
