Xml Entity 实体互转（XStream）

http://x-stream.github.io/tutorial.html

项目中用了 JAXB 方式 Xml Entity 实体互转（JAXB）

实体：

import com.thoughtworks.xstream.annotations.XStreamAlias;
import com.thoughtworks.xstream.annotations.XStreamConverter;
import com.thoughtworks.xstream.converters.basic.BooleanConverter;

import java.io.Serializable;
import java.util.Date;

/**
 * 患者基本信息
 */
@XStreamAlias("PatientInfo")
public class PatientInfoVo implements Serializable {

    /**
     * 患者ID
     */
    private String patientId;

    /**
     * 患者信息
     */
    @XStreamAlias("PAT_NAME")
    private String patientName;

    /**
     * 患者性别
     */
    @XStreamAlias("PatientGender")
    @XStreamConverter(value= BooleanConverter.class,booleans={false},strings={"男","女"})
    private Boolean gender;

    /**
     * 出生日期
     */
    @XStreamAlias("DATE_BIRTH")
    private Date patientBirthdate;

    /**
     *
     */
    @XStreamAlias("MedicalType")
    //@XStreamConverter(value= EnumToStringConverter.class,ints={1},strings={"门诊","急诊","住院"}) //TODO 待解决
    private Integer medicalType;

    public String getPatientId() {
        return patientId;
    }

    public void setPatientId(String patientId) {
        this.patientId = patientId;
    }

    public String getPatientName() {
        return patientName;
    }

    public void setPatientName(String patientName) {
        this.patientName = patientName;
    }

    public Date getPatientBirthdate() {
        return patientBirthdate;
    }

    public void setPatientBirthdate(Date patientBirthdate) {
        this.patientBirthdate = patientBirthdate;
    }

    public Boolean getGender() {
        return gender;
    }

    public void setGender(Boolean gender) {
        this.gender = gender;
    }

    public Integer getMedicalType() {
        return medicalType;
    }

    public void setMedicalType(Integer medicalType) {
        this.medicalType = medicalType;
    }

    @Override
    public String toString() {
        return "PatientInfoVo{" +
                "patientId='" + patientId + '\'' +
                ", patientName='" + patientName + '\'' +
                ", gender=" + gender +
                ", patientBirthdate=" + patientBirthdate +
                ", medicalType=" + medicalType +
                '}';
    }
}
