如何在Pojo类中触发路径变量

Question

我对spring boot很陌生，想做些新的事情。目前我有3个pojo类，它在user类中进行了扩展。我试图在所有setter id方法类中分配may@PathVariable partnerid的值，如下所示。我的问题是，spring boot是否提供了任何@annotation，可以将我的变量触发到我的Partner类中。我试图通过在setter方法中添加合作伙伴id来更新我的用户请求。

@RestController
@RequestMapping(value = "/push/fire/")
public class PushIdController {

    private final static Logger log = LoggerFactory.getLogger(PushIdController.class);

    @Autowired
    private ApplicationEventPublisher applicationEventPublisher;

    @RequestMapping(value = "/partner/{partnerId}", method = RequestMethod.POST)
    @annotation("new Partner().setPartnerId("PathVariable value")")
    public User userLogin(@PathVariable("partnerId")  String partnerId, @RequestBody User user){

        return user;

    }
}

public class Partner {

    private String partnerId;

    public String getPartnerId() {    return partnerId; }
    public void setPartnerId(String partnerId) { 
        this.partnerId = partnerId;
    }

    @Override
    public String toString() {
        return "Partner{" + "partnerId='" + partnerId + '\'' + '}';}
}

public class User {

    private final static Logger log = LoggerFactory.getLogger(User.class);

    private String userId;
    private Role role;
    private Video video;

     public void setUserId(String userId) {
        log.info("set-User-id");
        // getPartnerId null
        this.userId = userId + "_" + getPartnerId() ;
    }
    public void setRole(Role role) {
        log.info("set-User-Role");
        this.role = role;
    }

    public void setVideo(Video video) {
        log.info("set-User-Video");
        this.video = video;
    }
}

public class Role {

    private String roleId;

    public void setRoleId(String roleId) {
        // getPartnerId null
        this.roleId = roleId + "_"  +  getPartnerId();
    }

}

public class Video {

    private String videoId;

    public void setVideoId(String videoId) {
        this.videoId = videoId + "_"  + getPartnerId();
    }
}

Json请求：-

{
    "userId": "1d3ejjj",
    "userName": "[e-mail]",
    "phone": "03153817177",
    "role": {
         "roleId": "d423",
          "name": "nabeel ahmed"
    },
    "video": {
        "videoId": "123456d",
        "h": "25",
        "w": "25"

    }
}

Json响应：-

{
    "userId": "1d3ejjj_1d2d6dq0jhjhk",
    "userName": "[e-mail]",
    "phone": "03153817177",
    "role": {
         "roleId": "d423_1d2d6dq0jhjhk",
          "name": "nabeel ahmed"
    },
    "video": {
        "videoId": "123456d_1d2d6dq0jhjhk",
        "h": "25",
        "w": "25"

    }
}

正如我们所知，当我们在方法调用期间命中Json分配给Pojo调用setter方法的请求时，我只想更新每个类的id。我想像下面一样重新更新

user.setUserId(user.getUserId+"_"+partnerId);
user.getVideo().setVideoId(user.getVideo().getVideoId+"_"+partnerId);

并soo on......

经过大量搜索，我找到了将path变量触发到Pojo类中的方法<@annotation调用“InitBinder”Spring提供了@InitBinder注释，用于识别初始化WebDataBinder的方法，该WebDataBinder将参数填充到带注释的方法。因此，简单的方法是在Spring中注册一些自定义编辑器。因此，我通过获取请求参数的值，将我的伙伴对象创建到方法中注意：-当我在顶部发布时，我忘记了使用变量partnerId添加静态关键字

伙伴班

public class Partner {

    public static String partnerId;

    public static String getPartnerId() {    return partnerId; }
    public void setPartnerId(String partnerId) {
       this.partnerId = partnerId;
    }

    @Override
    public String toString() {
       return "Partner{" + "partnerId='" + partnerId + '\'' + '}';}
    }
}

在数据之后，我将此方法添加到我的控制器中，如

@InitBinder
public void initBinder(final WebDataBinder webdataBinder) {
    webdataBinder.registerCustomEditor(String.class, new PartnerFireId());
}

和PartnerFireId类

public class PartnerFireId extends PropertyEditorSupport {

    private Partner partner;

    public void setAsText(final String partnerKey) throws IllegalArgumentException {
        partner = new Partner();
        partner.setPartnerId(partnerKey);
    }

}
