一、新建实体bean,将xml文件转换为ThdReport与image列表

package com.etoak.bean;
import java.util.List;
public class ThdReport {
private Long id;
private Short type;
private String sn;
private String title;
private String name;
private String gender;
private String examDate;
private String birthday;
private Long patientId;
private String conclusion; //Summary检查结果
private String conclusionDesc;//Description检查描述
private String operatorPhysician;
private String performingPhysician;
private String referringPhysician;
private String age;
private List<Image> images;
public List<Image> getImages() {
return images;
}
public void setImages(List<Image> images) {
images = images;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Short getType() {
return type;
}
public void setType(Short type) {
this.type = type;
}
public String getSn() {
return sn;
}
public void setSn(String sn) {
this.sn = sn;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getExamDate() {
return examDate;
}
public void setExamDate(String examDate) {
this.examDate = examDate;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public Long getPatientId() {
return patientId;
}
public void setPatientId(Long patientId) {
this.patientId = patientId;
}
public String getConclusion() {
return conclusion;
}
public void setConclusion(String conclusion) {
this.conclusion = conclusion;
}
public String getConclusionDesc() {
return conclusionDesc;
}
public void setConclusionDesc(String conclusionDesc) {
this.conclusionDesc = conclusionDesc;
}
public String getOperatorPhysician() {
return operatorPhysician;
}
public void setOperatorPhysician(String operatorPhysician) {
this.operatorPhysician = operatorPhysician;
}
public String getPerformingPhysician() {
return performingPhysician;
}
public void setPerformingPhysician(String performingPhysician) {
this.performingPhysician = performingPhysician;
}
public String getReferringPhysician() {
return referringPhysician;
}
public void setReferringPhysician(String referringPhysician) {
this.referringPhysician = referringPhysician;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
@Override
public String toString() {
return "ThdReport [id=" + id + ", type=" + type + ", sn=" + sn
+ ", title=" + title + ", name=" + name + ", gender=" + gender
+ ", examDate=" + examDate + ", birthday=" + birthday
+ ", patientId=" + patientId + ", conclusion=" + conclusion
+ ", conclusionDesc=" + conclusionDesc + ", operatorPhysician="
+ operatorPhysician + ", performingPhysician="
+ performingPhysician + ", referringPhysician="
+ referringPhysician + ", age=" + age + ", Images=" + images
+ "]";
}
}

package com.etoak.bean;
public class Image {
private String path;
private String type;
private String content;
public String getPath() {
return path;
}
public void setPath(String path) {
this.path = path;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
@Override
public String toString() {
return "Image [path=" + path + ", type=" + type + ", content="
+ content + "]";
}
}

二、编写Image转换器，因为xml中的Image中既有属性又有内容

package com.etoak.test;
import com.etoak.bean.Image;
import com.thoughtworks.xstream.converters.Converter;
import com.thoughtworks.xstream.converters.MarshallingContext;
import com.thoughtworks.xstream.converters.UnmarshallingContext;
import com.thoughtworks.xstream.io.HierarchicalStreamReader;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
public class XStreamExpandConverter implements Converter{
@Override
public boolean canConvert(Class type) {
return type.equals(Image.class);
}
@Override
public Object unmarshal(HierarchicalStreamReader reader,
UnmarshallingContext context) {
Image s = new Image();
s.setPath(reader.getAttribute("Path"));
s.setType(reader.getAttribute("Type"));
s.setContent(reader.getValue());
return s;
}
@Override
public void marshal(Object source, HierarchicalStreamWriter writer,
MarshallingContext context) {
Image status = (Image) source;
writer.addAttribute("Path", status.getPath());
writer.addAttribute("Type", status.getType());
writer.setValue(status.getContent());
}
}

三、编写日期转换器，因为日期在xstream中不能直接转换为yyyy-MM-dd hh:mm:ss格式

package com.etoak.test;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import com.thoughtworks.xstream.converters.ConversionException;
import com.thoughtworks.xstream.converters.basic.AbstractSingleValueConverter;
public class XStreamYMDDateConverter extends AbstractSingleValueConverter {
private static final DateFormat DEFAULT_DATEFORMAT = new SimpleDateFormat(
"yyyy-MM-dd hh:mm:ss");
@Override
public boolean canConvert(Class type) {
return type.equals(Date.class);
}
@Override
public Object fromString(String str) {
// 这里将字符串转换成日期
try {
return DEFAULT_DATEFORMAT.parseObject(str);
} catch (ParseException e) {
e.printStackTrace();
}
throw new ConversionException("Cannot parse datedd " + str);
}
@Override
public String toString(Object obj) {
// 这里将日期转换成字符串
return DEFAULT_DATEFORMAT.format((Date) obj);
}
}

四、编写测试类

package com.etoak.test;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.util.List;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.etoak.bean.Image;
import com.etoak.bean.ThdReport;
import com.thoughtworks.xstream.XStream;
public class Test {
private XStream xstream = null;
private ThdReport report = null;
@org.junit.Test
public void readXML4InputStream() {
try {
xstream = new XStream();
String s = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
+"<ReportInfo>"
+"<Title></Title>"
+"<PatientId>320525198109110058</PatientId>"
+"<Name>吴志平</Name>"
+"<Gender>true</Gender>"
+"<Age>0</Age>"
+"<ExamDate>16-01-08 18:25:48</ExamDate>"
+"<Birthday>81-09-11 00:00:00</Birthday>"
+"<Description>动脉血管内膜回声增强，增厚，有中断现象。于血管前、后壁可见斑快回声（１，为软斑呈弱回声或等回声２，为硬斑回声增强，后方有声影），团块回声附着于血管壁上。"
