Example 2 with DefaultSpELExpressionEvaluator

use of org.springframework.data.mapping.model.DefaultSpELExpressionEvaluator in project spring-data-mongodb by spring-projects.

the class MappingMongoConverter method read.

    S instance = instantiator.createInstance(entity, provider);
    PersistentPropertyAccessor accessor = new ConvertingPropertyAccessor(entity.getPropertyAccessor(instance), conversionService);
    MongoPersistentProperty idProperty = entity.getIdProperty();
    DocumentAccessor documentAccessor = new DocumentAccessor(bson);
    // make sure id property is set before all other properties
    Object idValue = null;
    if (idProperty != null && documentAccessor.hasValue(idProperty)) {
        idValue = readIdValue(path, evaluator, idProperty, documentAccessor);
