java XML解析成Map

1.需要解析的文件.xml

<?xml version="1.0" encoding="UTF-8"?>
<request>
    <realName>test</realName>
    <identityNumber>411525152242417185276</identityNumber>
    <phone>1314456788</phone>
    <user>
        <value>1444444</value>
        <name>12334</name>
            <aa>
                <hehe>222222</hehe>
            </aa>

import com.ynet.utils.XmlUtils;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import org.dom4j.DocumentException;

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Map;

public class XmlDemoController {
    @RequestMapping(value="/xmlDemo")
    public Map<String, Object> xmlDocumentFile(){
        Document doc = null;
        try {
            FileInputStream fis = new FileInputStream("F:\\myweb\\gateway\\gateway2\\src\\main\\resources\\customer.xml");
            byte[] b = new byte[fis.available()];
