Java Spring集成MapStruct详情
目录
- 待转换的类
- 目标类
- 转换接口
- 测试类
前言:
MapStruct支持Spring的依赖注入机制,只须要在@Mapper注解中添加componentModel配置项,并设置为“spring”便可。
待转换的类
@Getter @Setter @ToString @Builder @AllArgsConstructor @NoArgsConstructor public class Spu { private Integer id; private String name; private String caption; private String pics; private String specs; private String unit; private Integer hot; private Integer comments; private Integer agrees; private Integer recommend; private Integer status; private String service; private String info; private Integer countryId; private String addr; private LocalDateTime createTime; private LocalDateTime updateTime; }
目标类
@Getter @Setter @ToString @Builder @AllArgsConstructor @NoArgsConstructor public class SpuVO { private Integer id; private String name; private String caption; private String pics; private String specs; private String unit; private String service; private String addr; }
转换接口
@Mapper(componentModel = "spring") public interface SpuTrans { List<SpuVO> spuList2SpuVOList(List<Spu> spuList); }
测试类
@Controller @RequestMapping() public class IndexController { @Resource private SpuTrans spuTrans; @Resource private SpuService spuService; @GetMapping("/list") public ModelAndView list(ModelAndView mav) { //轮播图 List<Spu> spuList = spuService.selectAll(); List<SpuVO> spuVOList = spuTrans.spuList2SpuVOList(spuList); mav.addObject("spuVOList", spuVOList); mav.setViewName("spu_list"); return mav; } }
