list Map 转list对象

使用alibaba json <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.37</version> </dependency> List<Map<String,Object>> list= iInventoryNeedService.listMaps(queryWrapper); List<InventoryNeedWeiDto> needDtos = JSON.parseArray(JSON.toJSONString(list), InventoryNeedWeiDto.class);

list对象 转另一个list对象

1引包 ：maven 2导入类 BeanMapperUtils

<dependency> <groupId>ma.glasnost.orika</groupId> <artifactId>orika-core</artifactId> </dependency> package com.liby.inventory.common.utils; import ma.glasnost.orika.MapperFacade; import ma.glasnost.orika.MapperFactory; import ma.glasnost.orika.impl.DefaultMapperFactory; import ma.glasnost.orika.metadata.Type; import java.util.List; public abstract class BeanMapperUtils { private static MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build(); public static <S,D> D map(S source,Class<D> clazz){ MapperFacade mapper = mapperFactory.getMapperFacade(); return mapper.map(source, clazz); } public static <S,D> void map(S source,D d){ MapperFacade mapper = mapperFactory.getMapperFacade(); mapper.map(source,d); } public static <S, D> D map(S s, Type<S> sType, Type<D> dType){ MapperFacade mapper = mapperFactory.getMapperFacade(); return mapper.map(s, sType, dType); } public static <S,D> List<D> mapAsList(List<S> source, Class<D> clazz){ MapperFacade mapper = mapperFactory.getMapperFacade(); return mapper.mapAsList(source, clazz); } }

2 使用

BeanMapperUtils.mapAsList(S source,Class clazz); source: 源对象 D：目标对象

对象转另一个对象

BeanMapperUtils.map(S source,Class clazz) source: 源对象 D：目标对象
