一、新建实体bean,将xml文件转换为ThdReport与image列表

1.  `package com.etoak.bean;`
2.   
3.  `import java.util.List;`
4.   
5.  `public class ThdReport {`
6.  `private Long id;`
7.  `private Short type;`
8.  `private String sn;`
9.  `private String title;`
10. `private String name;`
11. `private String gender;`
12. `private String examDate;`
13. `private String birthday;`
14. `private Long patientId;`
15. `private String conclusion; //Summary检查结果`
16. `private String conclusionDesc;//Description检查描述`
17. `private String operatorPhysician;`
18. `private String performingPhysician;`
19. `private String referringPhysician;`
20. `private String age;`
21. `private List<Image> images;`
22.  
23. `public List<Image> getImages() {`
24. `return images;`
25. `}`
26. `public void setImages(List<Image> images) {`
27. `images = images;`
28. `}`
29. `public Long getId() {`
30. `return id;`
31. `}`
32. `public void setId(Long id) {`
33. `this.id = id;`
34. `}`
35. `public Short getType() {`
36. `return type;`
37. `}`
38. `public void setType(Short type) {`
39. `this.type = type;`
40. `}`
41. `public String getSn() {`
42. `return sn;`
43. `}`
44. `public void setSn(String sn) {`
45. `this.sn = sn;`
46. `}`
47. `public String getTitle() {`
48. `return title;`
49. `}`
50. `public void setTitle(String title) {`
51. `this.title = title;`
52. `}`
53. `public String getName() {`
54. `return name;`
55. `}`
56. `public void setName(String name) {`
57. `this.name = name;`
58. `}`
59. `public String getGender() {`
60. `return gender;`
61. `}`
62. `public void setGender(String gender) {`
63. `this.gender = gender;`
64. `}`
65. `public String getExamDate() {`
66. `return examDate;`
67. `}`
68. `public void setExamDate(String examDate) {`
69. `this.examDate = examDate;`
70. `}`
71. `public String getBirthday() {`
72. `return birthday;`
73. `}`
74. `public void setBirthday(String birthday) {`
75. `this.birthday = birthday;`
76. `}`
77. `public Long getPatientId() {`
78. `return patientId;`
79. `}`
80. `public void setPatientId(Long patientId) {`
81. `this.patientId = patientId;`
82. `}`
83. `public String getConclusion() {`
84. `return conclusion;`
85. `}`
86. `public void setConclusion(String conclusion) {`
87. `this.conclusion = conclusion;`
88. `}`
89. `public String getConclusionDesc() {`
90. `return conclusionDesc;`
91. `}`
92. `public void setConclusionDesc(String conclusionDesc) {`
93. `this.conclusionDesc = conclusionDesc;`
94. `}`
95. `public String getOperatorPhysician() {`
96. `return operatorPhysician;`
97. `}`
98. `public void setOperatorPhysician(String operatorPhysician) {`
99. `this.operatorPhysician = operatorPhysician;`
100. `}`
101. `public String getPerformingPhysician() {`
102. `return performingPhysician;`
103. `}`
104. `public void setPerformingPhysician(String performingPhysician) {`
105. `this.performingPhysician = performingPhysician;`
106. `}`
107. `public String getReferringPhysician() {`
108. `return referringPhysician;`
109. `}`
110. `public void setReferringPhysician(String referringPhysician) {`
111. `this.referringPhysician = referringPhysician;`
112. `}`
113. `public String getAge() {`
114. `return age;`
115. `}`
116. `public void setAge(String age) {`
117. `this.age = age;`
118. `}`
119. `@Override`
120. `public String toString() {`
121. `return "ThdReport [id=" + id + ", type=" + type + ", sn=" + sn`
122. `+ ", title=" + title + ", name=" + name + ", gender=" + gender`
123. `+ ", examDate=" + examDate + ", birthday=" + birthday`
124. `+ ", patientId=" + patientId + ", conclusion=" + conclusion`
125. `+ ", conclusionDesc=" + conclusionDesc + ", operatorPhysician="`
126. `+ operatorPhysician + ", performingPhysician="`
127. `+ performingPhysician + ", referringPhysician="`
128. `+ referringPhysician + ", age=" + age + ", Images=" + images`
129. `+ "]";`
130. `}`
131.  
132. `}`

1.  `package com.etoak.bean;`
2.   
3.  `public class Image {`
4.  `private String path;`
5.  `private String type;`
6.  `private String content;`
7.  `public String getPath() {`
8.  `return path;`
9.  `}`
10. `public void setPath(String path) {`
11. `this.path = path;`
12. `}`
13. `public String getType() {`
14. `return type;`
15. `}`
16. `public void setType(String type) {`
17. `this.type = type;`
18. `}`
19. `public String getContent() {`
20. `return content;`
21. `}`
22. `public void setContent(String content) {`
23. `this.content = content;`
24. `}`
25. `@Override`
26. `public String toString() {`
27. `return "Image [path=" + path + ", type=" + type + ", content="`
28. `+ content + "]";`
29. `}`
30.  
31.  
32. `}`

二、编写Image转换器，因为xml中的Image中既有属性又有内容

1.  `package com.etoak.test;`
2.   
3.  `import com.etoak.bean.Image;`
4.  `import com.thoughtworks.xstream.converters.Converter;`
5.  `import com.thoughtworks.xstream.converters.MarshallingContext;`
6.  `import com.thoughtworks.xstream.converters.UnmarshallingContext;`
7.  `import com.thoughtworks.xstream.io.HierarchicalStreamReader;`
8.  `import com.thoughtworks.xstream.io.HierarchicalStreamWriter;`
9.   
10. `public class XStreamExpandConverter implements Converter{`
11.  
12. `@Override`
13. `public boolean canConvert(Class type) {`
14. `return type.equals(Image.class);`
15. `}`
16. `@Override`
17. `public Object unmarshal(HierarchicalStreamReader reader,`
18. `UnmarshallingContext context) {`
19. `Image s = new Image();`
20. `s.setPath(reader.getAttribute("Path"));`
21. `s.setType(reader.getAttribute("Type"));`
22. `s.setContent(reader.getValue());`
23. `return s;`
24. `}`
25. `@Override`
26. `public void marshal(Object source, HierarchicalStreamWriter writer,`
27. `MarshallingContext context) {`
28. `Image status = (Image) source;`
29. `writer.addAttribute("Path", status.getPath());`
30. `writer.addAttribute("Type", status.getType());`
31. `writer.setValue(status.getContent());`
32. `}`
33.  
34. `}`

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

1.  `package com.etoak.test;`
2.   
3.  `import java.text.DateFormat;`
4.  `import java.text.ParseException;`
5.  `import java.text.SimpleDateFormat;`
6.  `import java.util.Date;`
7.   
8.  `import com.thoughtworks.xstream.converters.ConversionException;`
9.  `import com.thoughtworks.xstream.converters.basic.AbstractSingleValueConverter;`
10.  
11. `public class XStreamYMDDateConverter extends AbstractSingleValueConverter {`
12.  
13. `private static final DateFormat DEFAULT_DATEFORMAT = new SimpleDateFormat(`
14. `"yyyy-MM-dd hh:mm:ss");`
15.  
16. `@Override`
17. `public boolean canConvert(Class type) {`
18. `return type.equals(Date.class);`
19. `}`
20.  
21. `@Override`
22. `public Object fromString(String str) {`
23. `// 这里将字符串转换成日期`
24. `try {`
25. `return DEFAULT_DATEFORMAT.parseObject(str);`
26. `} catch (ParseException e) {`
27. `e.printStackTrace();`
28. `}`
29. `throw new ConversionException("Cannot parse datedd " + str);`
30. `}`
31.  
32. `@Override`
33. `public String toString(Object obj) {`
34. `// 这里将日期转换成字符串`
35. `return DEFAULT_DATEFORMAT.format((Date) obj);`
36. `}`
37.  
38. `}`

四、编写测试类

1.  `package com.etoak.test;`
2.   
3.  `import java.io.IOException;`
4.  `import java.io.ObjectInputStream;`
5.  `import java.io.ObjectOutputStream;`
6.  `import java.util.List;`
7.   
8.  `import org.springframework.context.ApplicationContext;`
9.  `import org.springframework.context.support.ClassPathXmlApplicationContext;`
10.  
11. `import com.etoak.bean.Image;`
12. `import com.etoak.bean.ThdReport;`
13. `import com.thoughtworks.xstream.XStream;`
14.  
15. `public class Test {`
16. `private XStream xstream = null;`
17. `private ThdReport report = null;`
18. `@org.junit.Test`
19. `public void readXML4InputStream() {`
20.  
21. `try {`
22. `xstream = new XStream();`
23. `String s = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"`
24. `+"<ReportInfo>"`
25. `+"<Title></Title>"`
26. `+"<PatientId>320525198109110058</PatientId>"`
27. `+"<Name>吴志平</Name>"`
28. `+"<Gender>true</Gender>"`
29. `+"<Age>0</Age>"`
30. `+"<ExamDate>16-01-08 18:25:48</ExamDate>"`
31. `+"<Birthday>81-09-11 00:00:00</Birthday>"`
32. `+"<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。"`
33. `+"彩色血流于动脉处出现充盈缺损，血流变细，色彩明显。于狭窄的近端有明亮及增宽的高速血流。提示有侧支循环建立。　　"`
34. `+"频谱多普勒于狭窄处取样收缩期峰值加快达 cm/s，舒张期反向血流消失频谱增宽，病变远端动脉，峰值速度、平均速度均减慢，呈低幅、单相血流。"`
35. `+"频谱：有峰值后移现象</Description>"`
36. `+"<Summary>动脉管壁正常结构消失，呈不规则向心性增厚，最厚达mm，回声不均匀，管腔狭窄，最窄处为 mm。"`
37. `+"彩色血流于动脉处变细，出现五彩镶嵌或混叠现象（或彩色血流中断）。"`
38. `+"频谱多普勒于病变处动脉取样，血流速度明显加快，频带增宽，频窗减小（或消失），狭窄远端血流频谱为低阻力、低速，单相血流，"`
39. `+"动脉呈梭状（或囊状）扩张，内壁回声增强，不光滑。动脉瘤长：mm，宽：mm，开口mm。彩色血流于瘤体内呈红、蓝各半血流（旋流），此血流与动脉干内血流相连</Summary>"`
40. `+"<OperatorPhysician></OperatorPhysician>"`
41. `+"<PerformingPhysician>VINNOTester</PerformingPhysician>"`
42. `+"<ReferringPhysician>VINNOTester</ReferringPhysician>"`
43. `+"<Images>"`
44. `+"<Image Path=\"E9352D9A4212449F91E54A3980220691\" Type=\"1\">iVBORw0KGgoAAAANSUhEUgOVbWd//f2f671nr6</Image>"`
45. `+"<Image Path=\"87EFA807B0C84090B7001D72EB60F0F3\" Type=\"1\">iVBORw0KGgoAAAANSUhEUgAABOEAAALqCAYAAABzMk</Image>"`
46. `+"<Image Path=\"D975EFD027CF4672A8CA6B895A10159A\" Type=\"1\">iVBORw0KCCEML/BxnYyYrfKXeUAAAAAElFTkSuQmCC</Image>"`
47. `+"<Image Path=\"1ED902F498094A6496128594BE31B254\" Type=\"3\">iVBORw0KGgoAAAANSUhEUgAAgT0r9P/ug49yMtk8jAAAAAElFTkSuQmCC</Image>"`
48. `+"</Images>"`
49. `+"</ReportInfo>";`
50. `failRed("---------ObjectInputStream## XML --> javaObject---------");`
51. `  xstream.alias("ReportInfo",ThdReport.class);`
52. `xstream.aliasField("Title", ThdReport.class, "title");`
53. `xstream.aliasField("Name", ThdReport.class, "name");`
54. `xstream.aliasField("Gender", ThdReport.class, "gender");`
55. `xstream.aliasField("ExamDate", ThdReport.class, "examDate");`
56. `xstream.aliasField("Birthday", ThdReport.class, "birthday");`
57. `xstream.aliasField("PatientId", ThdReport.class, "patientId");`
58. `xstream.aliasField("Summary", ThdReport.class, "conclusion");`
59. `xstream.aliasField("Description", ThdReport.class, "conclusionDesc");`
60. `xstream.aliasField("OperatorPhysician", ThdReport.class, "operatorPhysician");`
61. `xstream.aliasField("PerformingPhysician", ThdReport.class, "performingPhysician");`
62. `xstream.aliasField("ReferringPhysician", ThdReport.class, "referringPhysician");`
63. `xstream.aliasField("Age", ThdReport.class, "age");`
64. `xstream.aliasField("Images", ThdReport.class, "images");`
65. `xstream.alias("Images", List.class);`
66. `xstream.alias("Image", Image.class);`
67. `xstream.registerConverter(new XStreamYMDDateConverter());`
68. `xstream.registerConverter(new XStreamExpandConverter());`
69. `ThdReport report = (ThdReport) xstream.fromXML(s);`
70. `System.out.println(report);`
71. `} catch (Exception e) {`
72. `e.printStackTrace();`
73. `}`
74. `}`
75.  
76. `public final void fail(String string) {`
77. `System.out.println(string);`
78. `}`
79. `public final void failRed(String string) {`
80. `System.err.println(string);`
81. `}`
82. `}`

五、简单介绍

1.  `alias(String 别名,Class class)方法给转换类起个别名，当xml中要转换为类的标签和类名不一致(包+类名都一致才为一致)时使用`
2.  `aliasField(String 别名, Class class, String 属性名)`

1.  `registerConverter(new 转换器)`
2.

六、下面是别人的xStream介绍可以参考下
