Class ImmutableMapPropertySource

  • 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
     }

        Parameters:
        name - the associated name
        source - the Map source (without null values in order to get consistent MapPropertySource.getProperty(java.lang.String) and MapPropertySource.containsProperty(java.lang.String) behavior)
