Confirm effectiveness of the cache of setter parameters

[yuu-nkjm]

Effectiveness of setterParameterTypesMap is confirmed by JMH. Updated code is slower than original one.

columnToAccessorMap.get(columnName).getSetterParameterType()

  private final Map<List<String>, List<Class<?>>> setterParameterTypesMap =
      new ConcurrentHashMap<>();

  private List<Class<?>> getSetterParameterTypes(List<String> columns) {
    return setterParameterTypesMap.computeIfAbsent(columns,
        k -> columns.stream()
            .map(columnName -> columnToAccessorMap.get(columnName).getSetterParameterType())
            .collect(Collectors.toList()));
  }

original code

        final Class<?> setterParameterType = setterParameterTypes.get(i - 1);
        final Object value =
            resultSetConverter.getValueBySetterParameterType(resultSet, i, setterParameterType);

updated code

        final Class<?> setterParameterType = columnToAccessorMap.get(columnName).getSetterParameterType();
        // or with cache
       // Class<?> setterParameterType = columnToAccessorMap.getSetterParameterType(columnName);
        final Object value =
            resultSetConverter.getValueBySetterParameterType(resultSet, i, setterParameterType);
