Question

How to suppress "Deprecated API usage" warnings for a specific class?

Answer

To suppress warnings for deprecated classes in the specific class only, not globally, ensure the correct warning type is used in the @SuppressWarnings annotation.

The correct annotation to use is:

@SuppressWarnings({"deprecation", "removal"})

Steps:

1. Add the @SuppressWarnings annotation with { "deprecation", "removal" } to the class or method declaration where the deprecated or for-removal class is being used.
2. Update imports if necessary and use fully qualified class names if issues persist.

For example:

import org.springframework.jdbc.core.support.JdbcDaoSupport;

// Application class that requires suppressing warnings
@SuppressWarnings({"removal"})
public class MyCustomJdbcDaoSupport extends org.springframework.jdbc.core.support.JdbcDaoSupport {

    public void someMethod() {
        // Your logic here
    }
}

In the above example, by ensuring the removal warning is explicitly suppressed and using the fully qualified name for the class, the warnings are silenced for this specific case only.
