Solution

• Add converter .

import cn.hutool.core.date.DateUtil;
import ma.glasnost.orika.MapperFacade;
import ma.glasnost.orika.MapperFactory;
import ma.glasnost.orika.MappingContext;
import ma.glasnost.orika.converter.BidirectionalConverter;
import ma.glasnost.orika.impl.DefaultMapperFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import ma.glasnost.orika.metadata.Type;

import java.time.LocalDateTime;
import java.util.Date;

/** * @author Zhou Zhongqing * @description:  towards Spring Register global objects for object replication  * @date 2022/5/20 14:20 */
@Configuration
public class OrikaMapperFactoryConfig {
    
    @Bean
    public MapperFactory mapperFactory() {
    
        return new DefaultMapperFactory.Builder().build();
    }

    @Bean
    public MapperFacade mapperFacade() {
    
        MapperFactory mapperFactory = mapperFactory();
        // Date  and LocalDateTime  Mutual conversion of 
        mapperFactory.getConverterFactory().registerConverter(new OrikaDateConverter());
        return mapperFactory.getMapperFacade();
    }

    /** * Date  and LocalDateTime  Mutual conversion of  */
    public class OrikaDateConverter extends BidirectionalConverter<Date, LocalDateTime> {
    


        @Override
        public LocalDateTime convertTo(Date source, Type<LocalDateTime> destinationType, MappingContext mappingContext) {
    
            return DateUtil.toLocalDateTime(source);
        }

        @Override
        public Date convertFrom(LocalDateTime source, Type<Date> destinationType, MappingContext mappingContext) {
    
            String format = "yyyy-MM-dd HH:mm:ss";
            String str = DateUtil.format(source, "yyyy-MM-dd HH:mm:ss");
            return DateUtil.parse(str, format);
        }

    }


}

DateUtil It uses hutool Of .

• When you meet Date Type to LocalDateTime Will enter OrikaDateConverter#convertTo Method . As shown in the figure below .

convertFrom The method is Date Type transfer LocalDateTime You will use

• In this way, the conversion can be successful .
