JavaSpring集成MapStruct详情

2022-11-13 09:11:16 集成 详情 JavaSpring

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;
    }
}
