由于使用Java中的JAXB库从XML代码中获取空结果,因此名称空间有什么问题?

jaxb namespaces xml java

下面的代码运行良好,我从这段代码中得到的结果如下图所示

@XmlRootElement(name = "AssumeRoleResponse")
public class AssumeRoleResponse {
  protected AssumeRoleResult assumeRoleResult;

  protected ResponseMetadata responseMetadata;

  public AssumeRoleResult getAssumeRoleResult() {
    return assumeRoleResult;
  }

  @XmlElement(name = "AssumeRoleResult")
  public void setAssumeRoleResult(AssumeRoleResult assumeRoleResult) {
    this.assumeRoleResult = assumeRoleResult;
  }

  public ResponseMetadata getResponseMetadata() {
    return responseMetadata;
  }

  @XmlElement(name = "ResponseMetadata")
  public void setResponseMetadata(ResponseMetadata responseMetadata) {
    this.responseMetadata = responseMetadata;
  }
}

我在上面的代码中使用了下面的XML字符串,效果很好,但是,

<AssumeRoleResponse>
  <AssumeRoleResult>
    <AssumedRoleUser>
      <AssumedRoleId>AR..............:Test</AssumedRoleId>
      <Arn>arn:aws:sts::7..........:assumed-role/amazon_spi_role/Test</Arn>
    </AssumedRoleUser>
    <Credentials>
      <AccessKeyId>A.............</AccessKeyId>
      <SecretAccessKey>my.......................</SecretAccessKey>
      <SessionToken>................................</SessionToken>
      <Expiration>2022-06-27T18:55:34Z</Expiration>
    </Credentials>
  </AssumeRoleResult>
  <ResponseMetadata>
    <RequestId>7241c78f-a975-4486-b4e0-6bf6d9b5c37b</RequestId>
  </ResponseMetadata>
</AssumeRoleResponse>

但是,当我在XmlRootElement中使用名称空间时,我无法从代码中得到结果,我尝试了几种方法,但没有从中得到任何结果

代码如下

@XmlRootElement(namespace = "https://sts.amazonaws.com/doc/2011-06-15/", name = "AssumeRoleResponse")
public class AssumeRoleResponse {
  protected AssumeRoleResult assumeRoleResult;

  protected ResponseMetadata responseMetadata;

  public AssumeRoleResult getAssumeRoleResult() {
    return assumeRoleResult;
  }

  @XmlElement(name = "AssumeRoleResult")
  public void setAssumeRoleResult(AssumeRoleResult assumeRoleResult) {
    this.assumeRoleResult = assumeRoleResult;
  }

  public ResponseMetadata getResponseMetadata() {
    return responseMetadata;
  }

  @XmlElement(name = "ResponseMetadata")
  public void setResponseMetadata(ResponseMetadata responseMetadata) {
    this.responseMetadata = responseMetadata;
  }
}

XML字符串在下面

<AssumeRoleResponse xmlns="https://sts.amazonaws.com/doc/2011-06-15/">
  <AssumeRoleResult>
    <AssumedRoleUser>
      <AssumedRoleId>AR..............:Test</AssumedRoleId>
      <Arn>arn:aws:sts::7..........:assumed-role/amazon_spi_role/Test</Arn>
    </AssumedRoleUser>
    <Credentials>
      <AccessKeyId>A.............</AccessKeyId>
      <SecretAccessKey>my.......................</SecretAccessKey>
      <SessionToken>................................</SessionToken>
      <Expiration>2022-06-27T18:55:34Z</Expiration>
    </Credentials>
  </AssumeRoleResult>
  <ResponseMetadata>
    <RequestId>7241c78f-a975-4486-b4e0-6bf6d9b5c37b</RequestId>
  </ResponseMetadata>
</AssumeRoleResponse>

结果如下 null result

命名空间有什么问题,请告知
