用Castor 处理XML文档

Castor（http://castor.exolab..org/）是一种将Java对象和XML自动绑定的开源软件。

Castor可以完成Java和XML的相互转换

 

第一步：新建javabean（PosPoilcyHistoryChangeResponse ）

  public class PosPoilcyHistoryChangeResponse {

 

//返回码

private String RetCode = "";

//返回信息

private String RetMsg = "";

 

private String PolicyNumber = "";

 

//保全业务笔数

private String preservationNumber;

//保全信息

private List<PreservationtDetail> prsList = new ArrayList<PreservationtDetail>();

 

//保单生效复效次数

private String InsPolicyEffRinst;

 

//保单生效复效信息

private List<InsPolicyDtDetail> InsPolicyDtList= new ArrayList<InsPolicyDtDetail>();

 

//保单保额变动次数

private String InsPolicyCvrChgNum;

//保单保额变动信息

private List<InsPolicyAplyDetail> InsPolicyAplyList = new ArrayList<InsPolicyAplyDetail>();

 

//理赔记录数

private String SetlOfClmsRcrdNum;

//理赔信息

private List<SetlOfClmsDetail> SetlOfClmsList= new ArrayList<SetlOfClmsDetail>();

public String getRetCode() {

return RetCode;

}

public void setRetCode(String retCode) {

RetCode = retCode;

}

public String getRetMsg() {

return RetMsg;

}

public void setRetMsg(String retMsg) {

RetMsg = retMsg;

}

public String getPolicyNumber() {

return PolicyNumber;

}

public void setPolicyNumber(String policyNumber) {

PolicyNumber = policyNumber;

}

public String getPreservationNumber() {

return preservationNumber;

}

public void setPreservationNumber(String preservationNumber) {

this.preservationNumber = preservationNumber;

}

public List<PreservationtDetail> getPrsList() {

return prsList;

}

public void setPrsList(List<PreservationtDetail> prsList) {

this.prsList = prsList;

}

public String getInsPolicyEffRinst() {

return InsPolicyEffRinst;

}

public void setInsPolicyEffRinst(String insPolicyEffRinst) {

InsPolicyEffRinst = insPolicyEffRinst;

}

public List<InsPolicyDtDetail> getInsPolicyDtList() {

return InsPolicyDtList;

}

public void setInsPolicyDtList(List<InsPolicyDtDetail> insPolicyDtList) {

InsPolicyDtList = insPolicyDtList;

}

public String getInsPolicyCvrChgNum() {

return InsPolicyCvrChgNum;

}

public void setInsPolicyCvrChgNum(String insPolicyCvrChgNum) {

InsPolicyCvrChgNum = insPolicyCvrChgNum;

}

public List<InsPolicyAplyDetail> getInsPolicyAplyList() {

return InsPolicyAplyList;

}

public void setInsPolicyAplyList(List<InsPolicyAplyDetail> insPolicyAplyList) {

InsPolicyAplyList = insPolicyAplyList;

}

public String getSetlOfClmsRcrdNum() {

return SetlOfClmsRcrdNum;

}

public void setSetlOfClmsRcrdNum(String setlOfClmsRcrdNum) {

SetlOfClmsRcrdNum = setlOfClmsRcrdNum;

}

public List<SetlOfClmsDetail> getSetlOfClmsList() {

return SetlOfClmsList;

}

public void setSetlOfClmsList(List<SetlOfClmsDetail> setlOfClmsList) {

SetlOfClmsList = setlOfClmsList;

}

 

 

}

第二步：将javaBean（PosPoilcyHistoryChangeResponse） 配置到castorMapping.xml

<?xml version="1.0" encoding="UTF-8"?>

 

<mapping>

</class>

<class name="com.siebre.itx.aia.PosPoilcyHistoryChangeResponse">

<map-to xml="ResponseDTO" />

<field name="RetCode"><bind-xml name="RetCode" /></field>

<field name="RetMsg"><bind-xml name="RetMsg" /></field>

<field name="PolicyNumber"><bind-xml name="PolicyNumber" /></field>

<field name="preservationNumber"><bind-xml name="preservationNumber" /></field>

<field name="InsPolicyEffRinst"><bind-xml name="InsPolicyEffRinst" /></field>

<field name="InsPolicyCvrChgNum"><bind-xml name="InsPolicyCvrChgNum" /></field>

<field name="SetlOfClmsRcrdNum"><bind-xml name="SetlOfClmsRcrdNum" /></field>

 

</class>

</mapping>

第三步：实现xml的解组

public static void main(String[] args) {

     //创建CastorMarshaller

     CastorMarshaller castorMarshaller = new CastorMarshaller();

     castorMarshaller.setMappingLocation(new ClassPathResource("AiaCastorMapping.xml",                           PosPoilcyHistoryChangeResponse.class));

     castorMarshaller.setIgnoreExtraElements(true);

     castorMarshaller.setIgnoreExtraAttributes(true);

     castorMarshaller.afterPropertiesSet();

 

     //读取要转换成javabean的xml

     FileInputStream input = new FileInputStream("response.xml")

     int length = input.available();

     byte[] buffer = new byte[length];

      input.read(buffer, 0, length);

 

      String  responseXML = new String(buffer);

 

     //将xml解组成对象

     SAXReader saxReader = new SAXReader();

     Document document = saxReader.read(new StringReader(responseXML));

     PosPoilcyHistoryChangeResponse nposbancaResDTO = (PosPoilcyHistoryChangeResponse)                           castorMarshaller.unmarshal(new DocumentSource(document));

     }

第四步：实现xml的编组

public static void main(String[] args) {

    CastorMarshaller castorMarshaller = getCastorMarshaller();

   //创建javaBean对象，并设值

    PosPoilcyHistoryChangeResponse nposbancaResDTO =                                        new PosPoilcyHistoryChangeResponseImpl();

     nposbancaResDTO.setRetCode(“aaa");

     nposbancaResDTO.setRetMes（“bbbb");

 

     DOMResult domResult = (DOMResult) new DomResultFactory().createResult(null);

     castorMarshaller.marshal(nposbancaResDTO , domResult);

     DOMReader domReader = new DOMReader();

     Document documentOut = domReader.read((org.w3c.dom.Document) domResult.getNode());

     

   //将javaBean编组成requestXMl

    StringWriter writer = new StringWriter();

    OutputFormat format = OutputFormat.createPrettyPrint();

     XMLWriter xmlWriter = new XMLWriter(writer, format);

     xmlWriter.write(documentOut);

     String requestXMl =  writer.toString();

}
