Spring Cloud Bindings Test Boot 2

Purpose of this module

For several Spring Cloud Bindings integrations, the properties bindings need to be different between Spring Boot 2 and Spring Boot 3.

For example, we can take some Redis properties bindings; with Spring Boot 2, they need to be mapped this way:

Property	Value
spring.redis.port	{port}
spring.redis.host	{host}

But in a Spring Boot 3 application, the mapping needs to be different because of changes with Spring Data Redis:

Property	Value
spring.data.redis.port	{port}
spring.data.redis.host	{host}

This module runs an application, based on Spring Boot 2, and checks whether the RedisConnectionFactory properly picked up the spring.redis.port and spring.redis.host values.

Pay attention to the 2 environment variables set in the pom.xml that set the JAVA_TOOL_OPTIONS and SERVICE_BINDING_ROOT - they allow Spring Boot Bindings to load the proper configuration in bindings/redis
