在controller层处理model的转换。

[AkagiYui]

模仿AnnouncementController，修改其他controller与service，在controller层进行request model和entity，entity和response model的转换。

AnnouncementController.java

    @PostMapping({"", "/"})
    public Boolean addAnnouncement(@RequestBody @Validated AddAnnouncementRequest request) {
        Announcement announcement = request.toAnnouncement();
        announcement.setAuthor(userService.getUser());
        return announcementService.addAnnouncement(announcement);
    }

    @GetMapping({"", "/"})
    public List<AnnouncementResponse> getAnnouncementList(@RequestParam(defaultValue = "false") Boolean all) {
        return AnnouncementResponse.fromAnnouncementList(announcementService.getAnnouncementList(all));
    }

    @GetMapping("/index")
    public List<AnnouncementDisplayResponse> getIndexAnnouncementList() {
        return AnnouncementDisplayResponse.fromAnnouncementList(announcementService.getAnnouncementDisplayList());
    }

AddAnnouncementRequest.java

@Data
public class AddAnnouncementRequest {

    @NotBlank(message = "{title cannot be empty}")
    @NotNull(message = "{title is missing}")
    private String title;

    private String content;

    public Announcement toAnnouncement() {
        return new Announcement()
                .setTitle(title)
                .setContent(content)
                .setEnabled(true);
    }

}

AnnouncementResponse.java

@Data
@Accessors(chain = true)
public class AnnouncementResponse {

    private String id;

    private String title;

    private String content;

    private String userId;

    private Boolean enabled;

    private Date createTime;

    private Date updateTime;

   public AnnouncementResponse(Announcement announcement) {
        this.id = announcement.getId();
        this.title = announcement.getTitle();
        this.content = announcement.getContent();
        this.userId = announcement.getAuthor().getId();
        this.enabled = announcement.getEnabled();
        this.createTime = announcement.getCreateTime();
        this.updateTime = announcement.getUpdateTime();
    }

    public static List<AnnouncementResponse> fromAnnouncementList(List<Announcement> announcementList) {
        return announcementList.stream()
                .map(AnnouncementResponse::new)
                .collect(Collectors.toList());
    }
}

目前涉及到的controller有：RoleController与UserController。
