Java Spring中的400错误请求错误

java json spring rest

Java Spring中的400错误请求错误,java,json,spring,rest,Java,Json,Spring,Rest,我发现了这个错误，知道是什么原因吗？我试图发送一个DTO，它有一个扩展了抽象类的对象列表。我想这个问题可能是因为DTO中的列表，或者是因为抽象类中的子类 @Autowired private RestClient restClient; @Override public ReceiptDto create_TicketIdentifier_For_Sale(TicketSaleDto tiDto) throws ServiceException { RestTem

我发现了这个错误，知道是什么原因吗？我试图发送一个DTO，它有一个扩展了抽象类的对象列表。我想这个问题可能是因为DTO中的列表，或者是因为抽象类中的子类

@Autowired
private RestClient restClient;


@Override
public ReceiptDto create_TicketIdentifier_For_Sale(TicketSaleDto tiDto)
        throws ServiceException {

    RestTemplate restTemplate = this.restClient.getRestTemplate();
    String url = this.restClient.createServiceUrl("/ticketIdentifier/");
    HttpHeaders headers = this.restClient.getHttpHeaders();
    //headers.add("Content-Type", MediaType.APPLICATION_FORM_URLENCODED_VALUE);
    HttpEntity<TicketSaleDto> entity = new HttpEntity<>(tiDto, headers);

    ReceiptDto ti = null;
    try {
        ParameterizedTypeReference<ReceiptDto> ref = new ParameterizedTypeReference<ReceiptDto>() {};
        ResponseEntity<ReceiptDto> response = restTemplate.exchange(URI.create(url), HttpMethod.POST, entity, ref);
        ti = response.getBody();
        //  System.out.println(ti.getEntryDto().getReceiptDto().getCustomerDto().getLastname());
    } catch (RestClientException e) {
        e.getStackTrace();
        throw new ServiceException("Could not retrieve ticketIdentifiers: " + e.getMessage());
    }
    return ti;

@Autowired

@凌驾
公开接收以创建用于销售的TicketIdentifier（TicketSaleDto tiDto）
抛出ServiceException{
RestTemplate RestTemplate=this.restClient.getRestTemplate（）；
字符串url=this.restClient.createServiceUrl（“/ticketIdentifier/”）；
HttpHeaders=this.restClient.getHttpHeaders（）；
//headers.add（“内容类型”，MediaType.APPLICATION\u FORM\u URLENCODED\u值）；
HttpEntity实体=新的HttpEntity（tiDto，标题）；
ReceiptDto ti=null；
试一试{
ParameteredTypeReference ref=新的ParameteredTypeReference（）{}；
ResponseEntity response=restemplate.exchange（URI.create（url）、HttpMethod.POST、entity、ref）；
ti=response.getBody（）；
//System.out.println（ti.getEntryDto（）.getReceiptDto（）.getCustomerDto（）.getLastname（））；
}捕获（RestClientException e）{
e、 getStackTrace（）；
抛出新的ServiceException（“无法检索ticketIdentifiers:+e.getMessage（））；
}
返回ti；

抽象类的子类导致问题。。。
