xml注解介紹

• @JacksonXmlRootElement
  • namespace屬性：用於指定XML根元素命名空間的名稱。
  • localname屬性：用於指定XML根元素節點標簽的名稱。
• @JacksonXmlProperty
  • namespace和localname屬性用於指定XML命名空間的名稱，isAttribute指定該屬 性作為XML的屬性（）還是作為子標簽（）.
• @JacksonXmlText注解將屬性直接作為未被標簽包裹的普通文本表現。
• @JacksonXmlCData將屬性包裹在CDATA標簽中。
• 集合元素的映射
  • @JacksonXmlElementWrapper可以將列表數據轉為XML節點。
  • useWrapping屬性設置是否設置外圍標簽名，默認true

封裝方法

    /**
     * javaBean轉xml
     *
     * @param javaBean javaBean對象
     * @return
     */
    public static String javaBean2Xml(Object javaBean) {
        try {
            XmlMapper xmlMapper = new XmlMapper();
            xmlMapper.setDefaultUseWrapper(false);
            //字段為null，自動忽略，不再序列化
            xmlMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
            //XML標簽名:使用駱駝命名的屬性名，
            xmlMapper.setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE);
            //設置轉換模式
            xmlMapper.enable(MapperFeature.USE_STD_BEAN_NAMING);
            return xmlMapper.writeValueAsString(javaBean);
        } catch (Exception e) {
            log.error("對象轉xml失敗，{}", javaBean);
            return null;
        }
    }

案例一

　　設置根標簽@JacksonXmlRootElement

@Data
@JacksonXmlRootElement(localName = "Response")
public class YuanTongLogisticsResponseVo {
    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlProperty
    private String logisticProviderID;

    @ApiModelProperty(value = "物流號(必填)")
    @JacksonXmlProperty
    private String txLogisticID;

    @ApiModelProperty(value = "成功失敗標識 true-成功;false-失敗(必填)")
    @JacksonXmlProperty
    private boolean success;

    @ApiModelProperty(value = "失敗原因(可空)")
    @JacksonXmlProperty
    private String reason;
}

測試一

    public static void main(String[] args) {
        YuanTongLogisticsResponseVo vo = new YuanTongLogisticsResponseVo();
        vo.setLogisticProviderID("AAA");
        vo.setTxLogisticID("BBBB");
        vo.setSuccess(true);
        vo.setReason("CCC");
        System.err.println(CommonUtil.javaBean2Xml(vo));
    }

<Response>
    <LogisticProviderID>AAA</LogisticProviderID>
    <TxLogisticID>BBBB</TxLogisticID>
    <Success>true</Success>
    <Reason>CCC</Reason>
</Response>

案例二

　　@JacksonXmlProperty 如果不設置localName默認都是首字母大寫

@Data
@JacksonXmlRootElement(localName = "Response")
public class YuanTongLogisticsResponseVo {
    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlProperty(localName = "logisticProviderID", isAttribute = true)
    private String logisticProviderID;

    @ApiModelProperty(value = "物流號(必填)")
    @JacksonXmlProperty(localName = "txLogisticID")
    private String txLogisticID;

    @ApiModelProperty(value = "成功失敗標識 true-成功;false-失敗(必填)")
    @JacksonXmlProperty(localName = "success")
    private boolean success;

    @ApiModelProperty(value = "失敗原因(可空)")
    @JacksonXmlProperty(localName = "reason")
    private String reason;
}

測試二

    public static void main(String[] args) {
        YuanTongLogisticsResponseVo vo = new YuanTongLogisticsResponseVo();
        vo.setLogisticProviderID("AAA");
        vo.setTxLogisticID("BBBB");
        vo.setSuccess(true);
        vo.setReason("CCC");
        System.err.println(CommonUtil.javaBean2Xml(vo));
    }

<Response logisticProviderID="AAA">
    <txLogisticID>BBBB</txLogisticID>
    <success>true</success>
    <reason>CCC</reason>
</Response>

案例三

一

　　@JacksonXmlElementWrapper設置集合外圍標簽名

@Data
@JacksonXmlRootElement(localName = "Response")
public class YuanTongLogisticsResponseVo {
    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlProperty(localName = "logisticProviderID")
    private String logisticProviderID;

    @ApiModelProperty(value = "物流號(必填)")
    @JacksonXmlProperty(localName = "txLogisticID")
    private String txLogisticID;

    @ApiModelProperty(value = "成功失敗標識 true-成功;false-失敗(必填)")
    @JacksonXmlProperty(localName = "success")
    private boolean success;

    @ApiModelProperty(value = "失敗原因(可空)")
    @JacksonXmlProperty(localName = "reason")
    private String reason;

    @JacksonXmlElementWrapper(localName = "res")
    @JacksonXmlProperty(localName = "other")
    private List<YuanTongLogisticsResponseTestVo> res;
}

@Data
public class YuanTongLogisticsResponseTestVo {
    @ApiModelProperty(value = "id(必填)")
    @JacksonXmlProperty(localName = "id")
    private String id;

    @ApiModelProperty(value = "name(必填)")
    @JacksonXmlProperty(localName = "name")
    private String name;
}

        vo.setLogisticProviderID("AAA");
        vo.setTxLogisticID("BBBB");
        vo.setSuccess(true);
        vo.setReason("CCC");
        List<YuanTongLogisticsResponseTestVo> voList = new ArrayList<>();
        YuanTongLogisticsResponseTestVo vo1 = new YuanTongLogisticsResponseTestVo();

@Data
@JacksonXmlRootElement(localName = "Response")
public class YuanTongLogisticsResponseVo {
    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlText
    private String logisticProviderID;

    @ApiModelProperty(value = "物流號(必填)")
    @JacksonXmlProperty(localName = "txLogisticID")
    private String txLogisticID;

<Response>AAA
    <txLogisticID>BBBB</txLogisticID>
    <success>true</success>
    <reason>CCC</reason>
</Response>

案例五

public class YuanTongLogisticsResponseVo {
    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlCData
    private String logisticProviderID;

    @ApiModelProperty(value = "物流號(必填)")
    @JacksonXmlProperty(localName = "txLogisticID")
    private String txLogisticID;

    @ApiModelProperty(value = "成功失敗標識 true-成功;false-失敗(必填)")
