Sending log from springboot application to cloudwatch in fargate instance

Question

We need to configure appender to cloudwatch in our log4j2.xml.
We are using ECS cluster with Fargate instance.
Use case is we need to categories logs in different log groups from same application based on business log type. There is way to send logs to different files using multiple loggers but how we can do same for cloud watch.
There are some libraries written for this but do we have some AWS cloudwatch log appender which we can use in our log4j2.xml. Please help

We use Spring Boot logging default and send output to the console. This should also work for non-Spring Boot. Then using CloudFormation configure logs in the TaskDefinition and LogGroups. You can do similar in the console with the TaskDefinition and create the CloudWatch logs separately.
