@XmlSchemaType(name=";normalizedString";)和@XmlJavaTypeAdapter(NormalizedStringAdapter.class)之间的JAXB差异
我正在编写一个没有XSD编译的JAXB类 有谁能告诉我两者的区别吗@XmlSchemaType(name=";normalizedString";)和@XmlJavaTypeAdapter(NormalizedStringAdapter.class)之间的JAXB差异,jaxb,Jaxb,我正在编写一个没有XSD编译的JAXB类 有谁能告诉我两者的区别吗 @XmlSchemaType(name=“normalizedString”) 私有字符串规范化; 及 @XmlJavaTypeAdapter(NormalizedStringAdapter.class) 私有字符串规范化; ? 使用上述注释时,在生成XML模式时,将为与此属性对应的属性/元素指定xsd:normalizedString类型 @XmlJavaTypeAdapter(NormalizedStringAdapte
@XmlSchemaType(name=“normalizedString”)
私有字符串规范化;
及
@XmlJavaTypeAdapter(NormalizedStringAdapter.class)
私有字符串规范化;
?
使用上述注释时,在生成XML模式时,将为与此属性对应的属性/元素指定xsd:normalizedString类型
@XmlJavaTypeAdapter(NormalizedStringAdapter.class)
private String normalized;
NormalizedStringAdapter
在解组操作期间执行工作:删除换行符、回车符和制表符
示例
input.xml
演示
package forum383861;
import java.io.*;
import javax.xml.bind.*;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamResult;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Root.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum383861/input.xml");
Root root = (Root) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
System.out.println();
jc.generateSchema(new SchemaOutputResolver() {
@Override
public Result createOutput(String arg0, String arg1) throws IOException {
StreamResult result = new StreamResult(System.out);
result.setSystemId(arg1);
return result;
}
});
}
}
输出
package forum383861;
import javax.xml.bind.annotation.*;
import javax.xml.bind.annotation.adapters.*;
@XmlRootElement
@XmlType(propOrder={"adapter", "schemaType", "control"})
public class Root {
private String adapter;
private String schemaType;
private String control;
@XmlJavaTypeAdapter(NormalizedStringAdapter.class)
public String getAdapter() {
return adapter;
}
public void setAdapter(String adpater) {
this.adapter = adpater;
}
@XmlSchemaType(name="normalizedString")
public String getSchemaType() {
return schemaType;
}
public void setSchemaType(String schemaType) {
this.schemaType = schemaType;
}
public String getControl() {
return control;
}
public void setControl(String control) {
this.control = control;
}
}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
<adapter> A B C </adapter>
<schemaType> A B
C </schemaType>
<control> A B
C </control>
</root>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="root" type="root"/>
<xs:complexType name="root">
<xs:sequence>
<xs:element name="adapter" type="xs:string" minOccurs="0"/>
<xs:element name="schemaType" type="xs:normalizedString" minOccurs="0"/>
<xs:element name="control" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
A、B、C
A B
C
A B
C
So@XmlSchemaType(name=“normalizedString”)
用于使用POJO生成XSD,而@XmlJavaTypeAdapter(NormalizedStringAdapter.class)
用于封送/取消封送,对吗?谢谢。有用于xs:token
的适配器吗?别管xs:token
。我刚找到。:)哎呀,我刚刚发现marshal(String s)
方法的折叠| NormalizedStringAdapter
apidoced带有No-op。只需返回与参数相同的字符串。
