使用jdk自带注解

在一个实体类上添加注解

@XmlRootElement(name="AppAccountList")
public class AppAccountListVO {

    private List<AppAccountEntity> appAccountList;

    public AppAccountListVO() {}

    public AppAccountListVO(List<AppAccountEntity> appAccountList) {
        this.appAccountList = appAccountList;
    }

    public List<AppAccountEntity> getAppAccountList() {
        return appAccountList;
    }

    @XmlElement(name="AppAccount")
    public void setAppAccountList(List<AppAccountEntity> appAccountList) {
        this.appAccountList = appAccountList;
    }
}

===========================================================

@XmlRootElement(name="AppAccount")
public class AppAccountEntity {

    private String code;

    private String appName;

    private String appUrl;

    private String redirectUrl;

    private String userName;

    private String passowrd;

    private String state;

    public String getCode() {
        return code;
    }

    @XmlElement(name = "Code")
    public void setCode(String Code) {
        this.code = Code;
    }

    public String getAppName() {
        return appName;
    }

    @XmlElement(name = "AppName")
    public void setAppName(String appName) {
        this.appName = appName;
    }

    public String getAppUrl() {
        return appUrl;
    }

    @XmlElement(name = "AppUrl")
    public void setAppUrl(String appUrl) {
        this.appUrl = appUrl;
    }

    public String getRedirectUrl() {
        return redirectUrl;
    }

    @XmlElement(name = "RedirectUrl")
    public void setRedirectUrl(String redirectUrl) {
        this.redirectUrl = redirectUrl;
    }

    public String getUserName() {
        return userName;
    }

    @XmlElement(name = "UserName")
    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassowrd() {
        return passowrd;
    }

    @XmlElement(name = "Password")
    public void setPassowrd(String passowrd) {
        this.passowrd = passowrd;
    }

    public String getState() {
        return state;
    }

    @XmlElement(name = "State")
    public void setState(String state) {
        this.state = state;
    }
}

main方法测试

public class Main {
    public static void main(String[] args) throws Exception{
        List list = new ArrayList();
        AppAccountEntity appAccountEntity = new AppAccountEntity();
        appAccountEntity.setCode("code");
        appAccountEntity.setAppName("appname");

        list.add(appAccountEntity);
        AppAccountListVO authVO = new AppAccountListVO(list);

        JAXBContext context = JAXBContext.newInstance(AppAccountListVO.class);
        Marshaller marshaller = context.createMarshaller();

        marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        //marshaller.marshal(authVO,System.out);
        // 打印到控制台

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        marshaller.marshal(authVO, baos);
        String xmlObj = new String(baos.toByteArray());
        // 生成XML字符串
        System.out.println(xmlObj);
    }
}

结果
