jaxb将javabean轉化成xml

對了對了，最近還接觸了jaxb,這個是啥呢，就是xml與JavaBean的互相轉換。

最近才知道，就算參數是xml，那也還是String類型。xml隻是個格式，隻是xml格式的String而已啦。

先來說一下我到的jaxb注解。

@XmlRootElement.将java類或枚舉映射成xml元素根節點，是唯一一個必須注解。name屬性指定根節點名稱，不寫就預設類名小寫。

@XmlElement.将java類的一個屬性映射為xml節點元素，name屬性可自定義元素名。

@XmlAttribute.将java的一個屬性映射為xml節點的屬性，name屬性可自定義屬性名。

@XmlType. 将java類或枚舉映射到xml模式類型。常與@[email protected]共用，proOrder屬性定義字段生成的xml節點順序。

@XmlAccessorType 定義映射這個類中的何種類型需要映射到XML。可接收四個參數，分别是：

XmlAccessType.FIELD：映射這個類中的所有字段到XML

XmlAccessType.PROPERTY：映射這個類中的屬性（get/set方法）到XML

XmlAccessType.PUBLIC_MEMBER：将這個類中的所有public的field或property同時映射到XML（預設）

XmlAccessType.NONE：不映射

@XmlElementWrapper.對于數組或集合，生成一個包裝該數組或集合的xml元素，該注解隻能用在集合上。

概念對我這種小白來說，簡直就是無字天書，是以說，上代碼。

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "BaseInfo")
public class BaseInfo {
    @XmlElement(name = "CardID")
    private String cardID;

    @XmlElement(name = "PatientName")
    private String patientName;

    @XmlElement(name = "BirthDate")
    private String birthDate;

    @XmlElement(name = "GenderCode")
    private String genderCode;

    @XmlElement(name = "NationCode")
    private String nationCode;

    @XmlElement(name = "EmployerOrgName")
    private String employerOrgName;

    @XmlElement(name = "IDR_OccupationCode")
    private String idr_OccupationCode;

    public String getCardID() {
        return cardID;
    }

        this.cardID = cardID;
    }
    public String getPatientName() {

    public String getNationCode() {

    }
    public void setNationCode(String nationCode) {
        this.nationCode = nationCode;
    }
    public String getEmployerOrgName() {
        return employerOrgName;
    }
    public void setEmployerOrgName(String employerOrgName) {
        this.employerOrgName = employerOrgName;
    }
    public String getIdr_OccupationCode() {
        return idr_OccupationCode;
    }
    public void setIdr_OccupationCode(String idr_OccupationCode) {
        this.idr_OccupationCode = idr_OccupationCode;
    }
    public String getOtherOccupationName() {
        return otherOccupationName;
    }
    public void setOtherOccupationName(String otherOccupationName) {
        this.otherOccupationName = otherOccupationName;
    }
    public String getGuardianName() {
        return guardianName;
    }
    public void setGuardianName(String guardianName) {
        this.guardianName = guardianName;
    }

    public String getTeleCom() {
        return teleCom;
    }

    public void setTeleCom(String teleCom) {
        this.teleCom = teleCom;
    }

    public String getOrgCountyCode() {
        return orgCountyCode;
    }

    public void setOrgCountyCode(String orgCountyCode) {
        this.orgCountyCode = orgCountyCode;
    }

    public String getOrgCode() {
        return orgCode;
    }

    public void setOrgCode(String orgCode) {
        this.orgCode = orgCode;
    }

    public String getLivingAddressAttributionCode() {
        return livingAddressAttributionCode;
    }

    public void setLivingAddressAttributionCode(String livingAddressAttributionCode) {
        this.livingAddressAttributionCode = livingAddressAttributionCode;
    }

    public String getLivingAddressCode() {
        return livingAddressCode;
    }

    public void setLivingAddressCode(String livingAddressCode) {
        this.livingAddressCode = livingAddressCode;
    }

    public String getLivingAddressDetails() {
        return livingAddressDetails;
    }

    public void setLivingAddressDetails(String livingAddressDetails) {
        this.livingAddressDetails = livingAddressDetails;
    }

    public String getIdcardCode() {
        return idcardCode;
    }

    public void setIdcardCode(String idcardCode) {
        this.idcardCode = idcardCode;
    }
}
           

public class BaseInfoTest extends BaseTest {
    @Autowired
    Jaxb2Marshaller marshaller;
    @Test
    public void getCardID() throws JAXBException{
        BaseInfo baseInfo = new BaseInfo();
        baseInfo.setCardID("1");
        baseInfo.setPatientName("65");
        baseInfo.setBirthDate("99");
        baseInfo.setGenderCode("555");
        baseInfo.setNationCode("99");
        baseInfo.setEmployerOrgName("7878");
        baseInfo.setEmployerOrgName("987554");
        baseInfo.setIdr_OccupationCode("sdfdsf");
        //将javabean轉換成xml(jaxb)
        JAXBContext context = JAXBContext.newInstance(Body.class);
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, false);
        marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        StringWriter writer = new StringWriter();
        marshaller.marshal(baseInfo, writer);
        System.out.println(writer.toString());
    }
}
           

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

暫時我就接觸這麼多，還會後續補充的。

加油，我們是最棒的仙女。

加一段将xml轉換成javabean的代碼

public static void unmarshallerByJaxb(String path, Object object) {
    try {
        JAXBContext jc = JAXBContext.newInstance(object.getClass());
            
        Unmarshaller unmarshaller = jc.createUnmarshaller();
            
        File file = new File(path);
        if (!file.exists()) {
            throw new FileNotFoundException("Can not load xml file!");
        }
            
        unmarshaller.unmarshal(file);
    } catch (JAXBException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
}
