I am working on a Springboot application, where a server startup (Tomcat) initializes bunch of classes. There are some unwanted ones being initialized and I am trying to improve the performance of startup so dont want to iniztialze these classes. I tried using @EnableAutoConfiguration annotation in my SpringBootServletInitializer with excludeName parameter as below :
@EnableAutoConfiguration(excludeName = "com.foler.subfolder.ExampleClass")
I also tried with another parameter @EnableAutoConfiguration(exclude = ExampelClass.class)

There are some unwanted ones being initialized and I am trying to improve the performance of startup so don't want to initialize these classes.
Auto-configuration (using @EnableAutoConfiguration) is always applied after user-defined beans have been registered, look here from the API here on the same point.
So, you should actually use @ComponentScan to filter the classes as part of the scanning so that the container might speed up (as it will not create bean objects from excluded packages/classes during the container startup).
@ComponentScan(basePackages = {"com.foler"},
excludeFilters = @ComponentScan.Filter(
type=FilterType.ASSIGNABLE_TYPE,
value = ExampelClass.class))
Is there any way I can add two or more classes for value parameter?
values accepts the type Class[] array , so you can set the multiple classses as value = {ExampelClass1.class, ExampelClass2.class}
