<sampleRoot>
	<list>
		<sampleElement>
			<id>1</id>
			<value>v1</value>
		</sampleElement>
		<sampleElement>
			<id>2</id>
			<value>v2</value>
		</sampleElement>
	</list>	
</sampleRoot>

In this case, prepare the following class. No special annotation is required.

@Data
public class SampleRoot1 {
  List<SampleElement> list;
}

@Data
public class SampleElement {
  String id;
  String value;
}

@RestController
public class SampleController {
  @PostMapping(value = "/hoge1")
  @RequestMapping(consumes = MediaType.TEXT_XML_VALUE)
  public String hoge1(@RequestBody SampleRoot1 s) {
    System.out.println("xml body " + s);
    return "ok";
  }

The execution result looks like the following.

xml body SampleRoot1(list=[SampleElement(id=1, value=v1), SampleElement(id=2, value=v2)])

Directly under root

Suppose that the following XML is sent. There is a repeating element directly under root.

<sampleRoot>
	<sampleElement>
		<id>1</id>
		<value>v1</value>
	</sampleElement>
	<sampleElement>
		<id>2</id>
		<value>v2</value>
	</sampleElement>
</sampleRoot>

In this case, add `@ JacksonXmlElementWrapper (useWrapping = false)` to the collection as shown below.

package jp.co.rakuten.rmsapi.order.notice.reciever.controller;

import java.util.List;

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;

import lombok.Data;

@Data
public class SampleRoot2 {
  @JacksonXmlElementWrapper(useWrapping = false)
  List<SampleElement> sampleElement;
}

I haven't read the documentation properly, so I don't think it's an accurate explanation, but it seems that useWrapping = false specifies that this property is not surrounded by any element.

Execution result.

xml body SampleRoot2(sampleElement=[SampleElement(id=1, value=v1), SampleElement(id=2, value=v2)])

If there is no annotation, the following error will occur. Feeling that trying to map an instance of SampleElement </ code> to `List <SampleElement>` itself has failed.
