Spring Data mongodb：'year‘的计算结果必须为整数

@Document(collection = "example")
public class ExampleEntity {
    @Id
    private String id;
    
    @Field(targetType = FieldType.INT32)
    private int year;
    
    // 其他字段和方法
}

@Configuration
public class MongoConfig extends AbstractMongoClientConfiguration {
    // 配置MongoDB连接等信息
    
    @Override
    public CustomConversions customConversions() {
        List<Converter<?, ?>> converters = new ArrayList<>();
        converters.add(new StringToIntegerConverter());
        return new MongoCustomConversions(converters);
    }
    
    // 其他配置方法
}

@WritingConverter
public class StringToIntegerConverter implements Converter<String, Integer> {
    @Override
    public Integer convert(String source) {
        return Integer.parseInt(source);
    }
}

@Repository
public interface ExampleRepository extends MongoRepository<ExampleEntity, String> {
    @Query("{'year': {$type: 16}}")
    List<ExampleEntity> findByYearIsInteger();
}
