xml注解介绍

• @JacksonXmlRootElement
  • namespace属性：用于指定XML根元素命名空间的名称。
  • localname属性：用于指定XML根元素节点标签的名称。
• @JacksonXmlProperty
  • namespace和localname属性用于指定XML命名空间的名称，isAttribute指定该属 性作为XML的属性（）还是作为子标签（）.
• @JacksonXmlText注解将属性直接作为未被标签包裹的普通文本表现。
• @JacksonXmlCData将属性包裹在CDATA标签中。
• 集合元素的映射
  • @JacksonXmlElementWrapper可以将列表数据转为XML节点。
  • useWrapping属性设置是否设置外围标签名，默认true

封装方法

    /**
     * javaBean转xml
     *
     * @param javaBean javaBean对象
     * @return
     */
    public static String javaBean2Xml(Object javaBean) {
        try {
            XmlMapper xmlMapper = new XmlMapper();
            xmlMapper.setDefaultUseWrapper(false);
            //字段为null，自动忽略，不再序列化
            xmlMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
            //XML标签名:使用骆驼命名的属性名，
            xmlMapper.setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE);
            //设置转换模式
            xmlMapper.enable(MapperFeature.USE_STD_BEAN_NAMING);
            return xmlMapper.writeValueAsString(javaBean);
        } catch (Exception e) {
            log.error("对象转xml失败，{}", javaBean);
            return null;
        }
    }

案例一

　　设置根标签@JacksonXmlRootElement

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

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

    @ApiModelProperty(value = "成功失败标识 true-成功;false-失败(必填)")
    @JacksonXmlProperty
    private boolean success;

    @ApiModelProperty(value = "失败原因(可空)")
    @JacksonXmlProperty
    private String reason;
}

测试一

    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 如果不设置localName默认都是首字母大写

@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 = "物流号(必填)")
    @JacksonXmlProperty(localName = "txLogisticID")
    private String txLogisticID;

    @ApiModelProperty(value = "成功失败标识 true-成功;false-失败(必填)")
    @JacksonXmlProperty(localName = "success")
    private boolean success;

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

测试二

    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设置集合外围标签名

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

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

    @ApiModelProperty(value = "成功失败标识 true-成功;false-失败(必填)")
    @JacksonXmlProperty(localName = "success")
    private boolean success;

    @ApiModelProperty(value = "失败原因(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;

    @ApiModelProperty(value = "物流公司ID(必填)")
    @JacksonXmlText
    private String logisticProviderID;
