XML 문자열을 Java 객체로 변환하는 중 CannotResolveClassException이 발생했습니다.

Question

JMS 대기열에서 문자열 형식의 XML을 가져 와서 POJO로 변환하는 뮬 흐름을 개발하려고합니다. JAXB 주석을 사용하여 xml과 클래스 속성 간의 매핑을 정의합니다. 다음은 JMS 큐에서 문자열로받은 샘플 xml입니다.

<FCUBS_NOTIFICATION xmlns="http://fcubs.ofss.com/notify/NOTIF_UP_TRANSACTION"> 
    <FCUBS_NOTIF_HEADER> 
     <MSGID>9132820000357947</MSGID> 
    </FCUBS_NOTIF_HEADER> 
</FCUBS_NOTIFICATION> 

내 POJO 클래스는 다음과 같습니다 :

package com.bean; 

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

@XmlRootElement(name="FCUBS_NOTIFICATION") 
public class Notification { 

    private String MSGID; 

    public String getMSGID() { 
     return MSGID; 
    } 

    @XmlElement(name="MSGID") 
    public void setMSGID(String mSGID) { 
     MSGID = mSGID; 
    } 
} 

나는 단 하나의 콩의

내 노새 흐름 설정 이루어진 com.bean 패키지에 jaxb.index 파일이 파일은 다음과 같습니다 :

나는 여기에 놓치고 있나요?

미리 감사드립니다.

Answer 1

xml-to-object-transformer의 serialization/deserialization은 XStream을 통해 수행되므로 JAXB는 그 시점에서 중요하지 않습니다.

당신은 별칭 필요

:

<mulexml:xml-to-object-transformer returnClass="com.bean.Notification" doc:name="XML to Object"> 
    <mulexml:alias name="FCUBS_NOTIFICATION" class="com.bean.Notification"/> 
</mulexml:xml-to-object-transformer>
