AWS serverless java container spring boot 2 to spring boot 3

Question

Below code is working in spring boot 2 using aws-serverless-java-container-springboot2

I tried using aws-serverless-java-container-springboot3 but in below apps there is no API calls/controller. Simply trying to init the bean so that aws lamba can be triggered.

Doesn't have proper sample to convert from aws-serverless-java-container-springboot2 to aws-serverless-java-container-springboot3 https://github.com/awslabs/aws-serverless-java-container/wiki/Quick-start---Spring-Boot3
