Question

我正在尝试使用Springboot消费通过REST Web服务接收的XML，对此我是新手，所以希望它是我犯的一个小错误。

我认为XML的结构可能不正确，但是我有以下内容。...

<ResultDetailsRequestModel>
<tournament>Premier League</tournament>
<fixture_date>2018-08-10</fixture_date>
<description>result</description>
<home_team>
    <team_name>Man Utd</team_name>
    <score>2</score>
    <ht_score>1</ht_score>
    <possession>46.3</possession>
    <shots_on_target>6</shots_on_target>
    <shots_off_target>1</shots_off_target>
    <corners>2</corners>
    <player gk="true" position="G" number="1">D de Gea</player>
    <player position="D" number="2">V Lindelof</player>
</home_team>
</ResultDetailsRequestModel>

但是无法读取播放器的详细信息，当对接收到的数据执行toString时，会得到以下信息。

ResultDetailsRequestModel(tournament=Premier League, fixture_date=Fri Aug 10 01:00:00 BST 2018, description=result, home_team=TeamResultXML(team_name=Man Utd, score=2, ht_score=1, possession=46.3, shots_on_target=6, shots_off_target=1, corners=2, players=null))

用

包围播放器标签时，我可以获得信息。

<players> ... </players>

但是更改XML在其他地方有很大的影响，因此希望按原样修复XML。

我的代码如下...

@RestController
@RequestMapping("results") // http://localhost:8888/results
public class ResultsController {

    @PostMapping(
            consumes = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE },
            produces = { MediaType.APPLICATION_XML_VALUE, MediaType.APPLICATION_JSON_VALUE }
    )
    public String createBets(@RequestBody ResultDetailsRequestModel resultDetails) {
        return "Received details: " + resultDetails.toString();
    }
}

@Data
@XmlRootElement(name="ResultDetailsRequestModel")
public class ResultDetailsRequestModel {
    private String tournament;
    private Date fixture_date;
    private String description;
    private TeamResultXML home_team;

}

@Data
@XmlRootElement(name="home_team")
public class TeamResultXML implements Serializable {
    private String team_name;
    private int score;
    private int ht_score;
    private double possession;
    private int shots_on_target;
    private int shots_off_target;
    private int corners;
    @XmlElement(name="player")
    private List<PlayerXML> players;

}

@Data
@XmlRootElement(name="player")
public class PlayerXML implements Serializable {
    @XmlAttribute(name="gk")
    private boolean goalkeeper;

    @XmlAttribute(name="position")
    private String position;

    @XmlAttribute(name="number")
    private int number;

    @XmlAttribute(name="sub")
    private String sub;

    @XmlValue
    private String value;
}

我收到的数据。...

ResultDetailsRequestModel(tournament=Premier League, fixture_date=Fri Aug 10 01:00:00 BST 2018, description=result, home_team=TeamResultXML(team_name=Man Utd, score=2, ht_score=1, possession=46.3, shots_on_target=6, shots_off_target=1, corners=2, players=null))

@Data批注是Lombok项目，因此可以创建吸气剂，设置器等。

当我通过将@XmlAccessorType(XmlAccessType.FIELD)添加到所有3个类中来解决此问题时，我得到了预期的输出：

ResultDetailsRequestModel [tournament=Premier League, fixture_date=Fri Aug 10 00:00:00 EDT 2018, description=result, home_team=TeamResultXML [team_name=Man Utd, score=2, ht_score=1, possession=46.3, shots_on_target=6, shots_off_target=1, corners=2, players=[PlayerXML [goalkeeper=true, position=G, number=1, sub=null, value=D de Gea], PlayerXML [goalkeeper=false, position=D, number=2, sub=null, value=V Lindelof]]]]

使用Springboot从REST发布请求中读取XML
