对xml文件的操作也可以借助hutool的XmlUtil.
1. xml格式
```xml
<root>
<deviceStatInfo onlineCount="64" offlineCount="2" errorCount="0"/>
<data>
<record id="0" name="5号楼10层流量计" status="预警2/正常1/异常3" time="2024-04-10 12:30"/>
<record id="1" name="5号楼13层流量计" status="预警2/正常1/异常3" time="2024-04-10 12:30"/>
<record id="2" name="5号楼16层流量计" status="预警2/正常1/异常3" time="2024-04-10 12:30"/>
<record id="3" name="5号楼19层流量计" status="预警2/正常1/异常3" time="2024-04-10 12:30"/>
</data>
</root>
```
2. 实体类
注意其中XmlElementWrapper和XmlElement的位置
点击查看实体类

3. 接口接收
@PostMapping(value = "/waterpipe", produces = {MediaType.APPLICATION_XML_VALUE})
public void waterpipe(@RequestBody EquipmentWaterPipeStatusMessage message) {
System.out.println("JSONUtil.toJsonStr(message) = " + JSONUtil.toJsonStr(message));
}
