public class ImmutableMapPropertySource
extends org.springframework.core.env.MapPropertySource

An immutable implementation of MapPropertySource that ensures the underlying map remains unmodifiable.

This class is useful in scenarios where the configuration properties should be protected from further modifications after initialization. It wraps the provided source map into an unmodifiable map using Collections.unmodifiableMap(Map).

Example Usage

     Map<String, Object> source = new HashMap<>();
     source.put("key1", "value1");
     source.put("key2", 42);

     ImmutableMapPropertySource propertySource = new ImmutableMapPropertySource("mySource", source);

     // The following operations will throw UnsupportedOperationException
     try {
         propertySource.getPropertySources().addLast(new CustomPropertySource());
     } catch (UnsupportedOperationException e) {
         // Expected exception
     }

ImmutableMapPropertySource

public ImmutableMapPropertySource(String name,
 Map source)
