foreach不适用于类型“java.lang.String”

Question

我正在尝试将数据库中列表中的项作为行中的单个值插入。如何循环发送的有效负载并将所有项插入到单独的行中？我试着找例子，没有运气。我无法循环并插入数据库中的值。

这是有效载荷

{"labsigned":["234568","234567","2345678","2344556","12335677","2345677","234556","234545"]}

@RequestMapping(path = "/labreport/createrordispatched", method = RequestMethod.POST)
public ResponseEntity<?> createDispatched(@RequestBody Dispatched dispatched){
    if(labDashboardService.createDispatched(dispatched)) {
        return ResponseEntity.status(HttpStatus.CREATED).body(true);
    }

    return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(false);
}

public boolean createDispatched(Dispatched dispatched) {
    List<Dispatched> newTickets = new ArrayList<>();

    dispatched.setCreatedBy(getCurrentUserEmail());
    dispatched.setDateCreated(System.currentTimeMillis());

    for(String labsigned:dispatched.getlabsigned()){
        Dispatched ticket = new Dispatched(
                dispatched.getCreatedBy(),
                dispatched.getDateCreated(),
                labsigned
        );
        newTickets.add(ticket);
    }
    dispatchedRepository.saveAll(newTickets);
    return true;
}

@Entity
@Table(name = "DISPATCHED")
public class Dispatched {
    private String id;
    private String labsigned;
    private Long dateCreated;
    private String createdBy;

    public Dispatched(){}
    public Dispatched(String createdBy, Long dateCreated, String labsigned){
        this.labsigned = rorlabsigned;
        this.dateCreated = dateCreated;
        this.createdBy = createdBy;

    }
//getters and setters

  for(String rorlabsigned:dispatched.getRorlabsigned())

错误消息指示getterdispatched.getRorlabSigned()不返回集合。它返回一个字符串。不能使用foreach循环字符串。我想您需要一个集 。尝试重构代码的那一部分。
