US Patent 11544090 Implementing dependency injection via direct bytecode generation

A system includes a memory and a processor in communication with the memory. The processor is configured to process at least one application file and generate bytecode, responsive to processing the at least one application file, from the at least one application file prior to start-up time. The bytecode contains a metamodel and the metamodel controls dependency injection. Additionally, the metamodel is classified as at least one of a first class that is generated at start-up time, a second class that is generated as source files and compiled at compile time, and a third class that is generated directly as bytecode. The processor is also configured to store the bytecode associated with the third class of metamodel.
