Cannot deserialize (convert) unwrapped list when it's second in class using Jackson XmlWrapper

Question

I am trying to use XmlMapper from Jackson to deserialize some simple xml files containing unwrapped lists.

My code:

package zm.study.xmlserialize.jac         


        

Answer 1

Try using below code sample

This sample xml file

 
  
     
        901
     
     
        902
     
     
        903
     
     
        904
     
     
        905
     
     
        906
     
     
        907
     
     
        908
     
     
        909
     
     
        910
     
     
        911
     
  
  

package com.inma.itp.queue.models;

import java.util.List;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

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

import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@XmlRootElement(name = "UsrAuthentRs")
@XmlAccessorType(XmlAccessType.FIELD)
public class UsrAuthentRs {


@XmlElement(name = "Body")
private Body body = new Body();

@Data
public static class Body {
    @XmlElement(name = "BankUsrInfo")
    private BankUsrInfo bankUsrInfo = new BankUsrInfo();


    @Data
    @XmlAccessorType(XmlAccessType.FIELD)
    public static class BankUsrInfo {


        @XmlElement(name = "RoleInfo")
        @JacksonXmlElementWrapper(useWrapping = false)
        private List roles;


        @Data
        @NoArgsConstructor
        @XmlAccessorType(XmlAccessType.FIELD)
        public static class RoleInfo {
            @XmlElement(name = "RoleId")
            private String roleId;

        }
    }
}

}

This main method which you can convert xml file to Pojo class

XmlMapper mapper = new XmlMapper();
UsrAuthentRq deserializedData = xmlMapper.readValue(YouXmlHere, UsrAuthentRq.class);
