最近项目中使用castor进行JAVA对象和XML之间的转换时，出现了一个问题。

有3个需要映射的bean如下：

Java代码

1 package model;

2

3 public class InformConfig {

4

5 private Inform inform;

6 private EmailServer emailServer;

7 public Inform getInform() {

8 return inform;

9 }

10 public void setInform(Inform inform) {

11 this.inform = inform;

12 }

13 public EmailServer getEmailServer() {

14 return emailServer;

15 }

16 public void setEmailServer(EmailServer emailServer) {

17 this.emailServer = emailServer;

18 }

19

20 }

Java代码

21 package model;

22

23 public class EmailServer {

24

25 private String pop3;

26 private String smtp;

27 private String name;

28 private String password;

29 public String getPop3() {

30 return pop3;

31 }

32 public void setPop3(String pop3) {

33 this.pop3 = pop3;

34 }

35 public String getSmtp() {

36 return smtp;

37 }

38 public void setSmtp(String smtp) {

39 this.smtp = smtp;

40 }

41 public String getName() {

42 return name;

43 }

44 public void setName(String name) {

45 this.name = name;

46 }

47 public String getPassword() {

48 return password;

49 }

50 public void setPassword(String password) {

51 this.password = password;

52 }

53

54

55

56 }

Java代码

57 package model;

58

59 public class Inform {

60

61 private String smsContent;

62 private String emailContent;

63 private String smsDest;

64 private String emailDest;

65

66 public String getSmsContent() {

67 return smsContent;

68 }

69 public void setSmsContent(String smsContent) {

70 this.smsContent = smsContent;

71 }

72 public String getEmailContent() {

73 return emailContent;

74 }

75 public void setEmailContent(String emailContent) {

76 this.emailContent = emailContent;

77 }

78 public String getSmsDest() {

79 return smsDest;

80 }

81 public void setSmsDest(String smsDest) {

82 this.smsDest = smsDest;

83 }

84 public String getEmailDest() {

85 return emailDest;

86 }

87 public void setEmailDest(String emailDest) {

88 this.emailDest = emailDest;

89 }

90

91

92

93 }

规则文件mapping.xml配置：

Java代码

94

95

96 "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"

97 "http://castor.exolab.org/mapping.dtd">

98

测试编组的代码如下：

Java代码

142 Inform inform = new Inform();

143 inform.setEmailContent("email content");

144 inform.setSmsContent("sms content");

145 inform.setEmailDest("fw@163.com");

146 inform.setSmsDest("133********");

147 EmailServer emailServer = new EmailServer();

148 emailServer.setName("fw");

149 emailServer.setPassword("123");

150 emailServer.setPop3("163.pop3.com");

151 emailServer.setSmtp("163.smtp.com");

152 InformConfig informConfig = new InformConfig();

153 informConfig.setEmailServer(emailServer);

154 informConfig.setInform(inform);

155

156 Mapping map = new Mapping();

157 map.loadMapping("mapping.xml");

158 Marshaller ma = new Marshaller(new FileWriter("informConfig.xml"));

159 ma.setMapping(map);

160 ma.marshal(informConfig);

产生的informConfig.xml如下：

Java代码

161

162

163

164 sms content

165 email content

166 133********

167 fw@163.com

168

169

170 163.pop3.com

171 163.smtp.com

172 fw

173 123

174

175

以上均达到了我的要求，但是在解组时获得的InformConfig对象中的属性全部都是NULL，测试解组的代码如下

Java代码

176 Unmarshaller uma = new Unmarshaller(map);

177 //这里获得的InformConfig对象ic中的属性均为NULL

178 InformConfig ic =

179 (InformConfig) uma.unmarshal(InformConfig.class, new FileReader("informConfig.xml"));
