Java Spring集成MapStruct详情（java培训）

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 sVajfDcAQinfo;

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 spuList2SpuVOList(List 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 spuList = spuService.selectAll();

List spuVOList = spuTrans.spuListsVajfDcAQ2SpuVOList(spuList);

mav.addObject("spuVOList", spuVOList);

mav.setViewName("spu_list");

rhttp://eturn mav;

}

}
