如何在 spring 引导中序列化和反序列化 XML？

Question

I have an XML request and the response of media type TEXT/XML.

I am trying to serialize and deserialize the request and response in spring boot.

Request body as follows.

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:ws="http://ws">
   <soapenv:Header />
   <soapenv:Body>
      <ws:doKF>
         <parameterIn><![CDATA[<KFWS>
  <RqUID>0f73a59f-8388-492e-b17d-ba1fb1b1d2fd</RqUID>
  <ClientApp>A</ClientApp>
  <SignOn>
    <Username>web</Username>
    <Password>Web@123</Password>
  </SignOn>
  <CaListOfflineRq>
    <CR>123456</CR>
  </CaListOfflineRq>
</KFWS>]]></parameterIn>
      </ws:doKF>
   </soapenv:Body>
</soapenv:Envelope>

The response as follows

            <?xml version="1.0" encoding="UTF-8"?>
        <NS1:Envelope xmlns:NS1="http://schemas.xmlsoap.org/soap/envelope/">
           <NS1:Body>
              <NS2:doKFResponse xmlns:NS2="http://ws">
                 <NS2:parameterOut>
                    <KFWS>

                                <Status>Expired</Status>
                                <Number>20000</Number>
                             </CaCard>
                             <CaCard>

                                <CaToken>2140</CaToken>
                                <Name>xxxxxxxxxxxxxxx</Name>

                                <Status>Expired</Status>
                                <Number>20000</Number>
                             </CaCard>
                          </CaCards>
                       </CaListOfflineRs>
                    </KFWS>
                 </NS2:parameterOut>
              </NS2:doKFResponse>
           </NS1:Body>
        </NS1:Envelope>

I got the response using the Feign client in the string and I need to de-serialise the response to the JSON

Answer 1

Looks like it's SOAP response.

See Spring tutorial that shows how to consume such service.

Answer 2

You can use Jackson to serialize and deserialize your xml. You need to look at your xml structure and create the proper POJOs. Here you can find how to do the serialization/deserialization https://www.baeldung.com/jackson-xml-serialization-and-deserialization
