从 Java 8 迁移到 Java 17-XML 数据，在 Controller JDK 17 Spring 3.0.5 中从 postman 的 requestBody 中作为 NULL 接收

问：

'从 Java 8 迁移到 Java 17，Spring 3.0.5 面临问题。 当我从邮递员发送 XML 数据时，在控制器中获取 Null，而不是传递的实际值。 我正在使用 JDK 17 + Spring 版本 - 3.0.5。 标头 Content-Type - application/xml。io.swagger.v3.oas.annotations.parameters.RequestBody;

import jakarta.validation.constraints.NotNull; 
import jakarta.xml.bind.annotation.XmlElement;
import jakarta.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="HEADERMLW")
public class Headmlw implements Serializable  
{
private String routeId;
@NotNull(message = "RouteId cannot be empty ")
@XmlElement(name = "RouteId")
public String getRouteId() {
  return routeId;
 }
public void setRouteId(String routeId) {
 this.routeId = routeId;
  }
}`

控制器

import org.springframework.beans.factory.annotation.Autowired;    
import org.springframework.beans.factory.annotation.Value;    
import org.springframework.http.HttpStatus;

使用以下依赖项

    <dependency>
        <groupId>jakarta.xml.bind</groupId>
        <artifactId>jakarta.xml.bind-api</artifactId>

如果我使用import org.springframework.web.bind.annotation.RequestBody;
它给出了以下错误响应，尽管我在 requestbody 中发送 xml 数据

{     "type": "about:blank", 
      "title": "Bad Request", 
      "status": 400,  
      "detail": "Invalid request content."
  }
