Question

我需要在Spring Boot应用程序中解析这样的XML文档：

Code > Injected language fragment

这是我<Transaction id="{ID}" vs="{VS}" uniq="{UNIQ}"> <Data field1="{VAL1}" field2="{VAL2}" /> </Transaction>

中的端点方法

@RestController

和@RequestMapping(value = "/transaction", method = RequestMethod.POST) public ApiClient transaction(@RequestBody TransactionRequest transactionRequest) { LOGGER.debug(transactionRequest); return null; }类：

Transaction

和@XmlRootElement(name = "Transaction") @XmlAccessorType(XmlAccessType.FIELD) @XmlSeeAlso(TransactionRequestData.class) public class TransactionRequest { @XmlElement(name = "id") private long id; @XmlElement(name = "vs") private String vs; @XmlElement(name = "uniq") private String uniq; @XmlElement(name = "data") private TransactionRequestData data; }

TransactionRequestData

但是这只绑定了@XmlRootElement(name = "Data") @XmlAccessorType(XmlAccessType.FIELD) public class TransactionRequestData { @XmlElement(name = "field1") private String field1; public String getField1() { return field1; } public void setField1(String field1) { this.field1 = field1; } }个元素数据，但没有绑定Transaction元素。

有没有办法解析子元素？

Answer 1

id，vs，uniq属性是你的情况下的xml属性。

使用@XmlAttribute将@XmlElement注释更改为正确的TransactionRequest pojo。

使用以下内容：

@XmlRootElement(name = "Transaction")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlSeeAlso(TransactionRequestData.class)
public class TransactionRequest {

    @XmlAttribute(name = "id")
    private long id;

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

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

    @XmlElement(name = "data")
    private TransactionRequestData data;

    ....getters & setters ommited
}


@XmlRootElement(name = "Data")
@XmlAccessorType(XmlAccessType.FIELD)
public class TransactionRequestData {

    @XmlAttribute(name = "field1")
    private String field1;

    public String getField1() {
        return field1;
    }

    public void setField1(String field1) {
        this.field1 = field1;
    }
     ....getters & setters ommited
}

并且不要忘记为房产添加吸气剂和制定者。

通过@RequestBody解析带有子元素的XML Web请求
