How to Assign a Custom Logger Variable Name in Lombok?

How can I assign a custom logger variable name when using Lombok's @Slf4j annotation in my Java application?

@Slf4j("customLogger") 
public class MyClass {
    public void myMethod() {
        customLogger.info("This is a log message");
    }
}

Using Lombok's @Slf4j annotation allows for easy logging in Java applications. By default, the logger variable name is 'log', but you can customize it to suit your needs. This flexibility is particularly useful for maintaining clarity in logging, especially in classes with multiple loggers or specific naming conventions.

import lombok.extern.slf4j.Slf4j;

@Slf4j("customLogger") 
public class MyClass {
    public void performAction() {
        customLogger.info("Action performed successfully!");
    }
}

Causes

• Default logger variable name does not meet project naming conventions.
• Need to distinguish between multiple loggers within the same class.

Solutions

• Use Lombok's @Slf4j annotation with a custom parameter to specify the logger name.
• Example: Use @Slf4j("customLogger") to create a logger named 'customLogger'.
• Invoke the logger using the specified name, e.g., customLogger.info(...);

Mistake: Forgetting to import Lombok annotations.

Solution: Ensure you have the correct Lombok imports in your Java file.

Mistake: Attempting to use the logger name without correctly defining it in the annotation.

Solution: Double-check that the logger name matches what you've defined in the @Slf4j annotation.
