我遇到了内容协商的问题，我正在尝试解决它，但不知道具体如何。所以，我有端点：

 @PostMapping(value = "/v2/transaction", consumes = MediaType.ALL_VALUE, produces = {"application/xml", "application/json"})
    public @ResponseBody
    ResponseEntity<TransactionResponse> executeTransaction(@RequestBody TransactionRequest request) {

        printerService.printRequestLog(request);

        TransactionResponse response = null;
        try {
            response = bhnProcessingService.processTransaction(request);
        } catch (GsStatusCodeException gse) {
            Map<String, String> responseMap = gse.getResponseMap();
            response = gsStatusCodeException.gsStatusCodeExceptionHandling(responseMap, request);
            bhnResponseService.save(bhnResponseMapper.dtoToEntity(response));
            printerService.printResponseLog(response);
            return ResponseEntity.ok(response);
        }
        printerService.printResponseLog(response);
        return ResponseEntity.ok(response);
    }

我知道consumes并且produces没有必要，但它是项目风格的语法，所以我保持原样。有这样的要求：

@XmlRootElement(name = "request")
@JsonRootName("request")
public class TransactionRequest implements Serializable {

    private static final long serialVersionUID = -4928904121335557260L;

    public BhnHeader header = new BhnHeader();
    public BhnTransaction transaction = new BhnTransaction();

}

传入的请求需要转换为另一个对象（简单的 DTO）并通过 SOAP 发送到端服务器。然后，当我收到来自 SOAP 服务器的响应时，传出 DTO 我将转换回与请求类型相同的对象并发送给请求发起者。如果是请求，JSON则响应应该是JSON，与 相同XML。而且我不知道该怎么做。我找到了一些指南，但它们都包含 Spring MVC。就像是：

@Configuration
@EnableWebMvc
public class RestApiApplication extends WebMvcConfigurerAdapter {

@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {

   configurer.favorPathExtension(false).
   favorParameter(true).
   ignoreAcceptHeader(false).
   useJaf(false).
   defaultContentType(MediaType.APPLICATION_XML).
   mediaType("xml", MediaType.APPLICATION_XML).
   mediaType("json", MediaType.APPLICATION_JSON);
}

你能给我一些关于如何解决这个问题的建议吗？欣赏它！PS并不意味着硬编码。通常情况下：截止日期是昨天......

解决方案：我添加@RequestHeaders HttpHeaders httpHeaders到方法参数中，它让我有机会检查所有 HTTP 标头。每个 HTTP 请求都至少需要我的任务标头之一：内容类型或接受。所以，它适用于我和我的问题。希望任何人也可以使用它。
