One of the reasons the market adopted Java so firmly is the power of the environment around it: the ecosystem is enormous. We have at least two or more frameworks to work on multiple proposals, besides the platforms where it assembles several solutions to work as one, such as Spring, Quarkus, Jakarta EE, and MicroProfile. 

Looking deep into both Jakarta EE and MicroProfile, we have a glue, the CDI, which guarantees consistency and the perfect harmony around both solutions.
