为JAXB书写工具类

看代码,应该很好理解的:

@XmlRootElement(name="schema",namespace="http://www.w3.org/2001/XMLSchema")public class Schema {private Element element;public Element getElement() {return element;}@XmlElement(name="element",namespace="http://www.w3.org/2001/XMLSchema")public void setElement(Element element) {this.element = element;}public Schema(Element element) {super();this.element = element;}public Schema() {super();// TODO Auto-generated constructor stub}}

public class Element {private String name;private ComplexType complexType;public static String NAME_UDRQueryRequest ="UDRQueryRequest";public static String NAME_UDRQueryResponse ="UDRQueryResponse";public static String NAME_UDRNotifyRequest ="UDRNotifyRequest";public static String NAME_UDRNotifyResponse ="UDRNotifyResponse";public static String getResType(String nameType){if(NAME_UDRQueryRequest.equalsIgnoreCase(nameType))return NAME_UDRQueryResponse;else if(NAME_UDRNotifyRequest.equalsIgnoreCase(nameType))return NAME_UDRNotifyResponse;return null;}public String getName() {return name;}@XmlAttributepublic void setName(String name) {this.name = name;}public ComplexType getComplexType() {return complexType;}@XmlElement(name="complexType",namespace="http://www.w3.org/2001/XMLSchema")public void setComplexType(ComplexType complexType) {this.complexType = complexType;}public Element(String name, ComplexType complexType) {super();this.name = name;this.complexType = complexType;}public Element() {super();// TODO Auto-generated constructor stub}}

public class ComplexType {private Sequence sequence;public Sequence getSequence() {return sequence;}@XmlElement(name="sequence",namespace="http://www.w3.org/2001/XMLSchema")public void setSequence(Sequence sequence) {this.sequence = sequence;}public ComplexType(Sequence sequence) {super();this.sequence = sequence;}public ComplexType() {super();// TODO Auto-generated constructor stub}}

public class Sequence {private List<Elements> elements;public List<Elements> getElements() {return elements;}@XmlElement(name="element",namespace="http://www.w3.org/2001/XMLSchema")public void setElements(List<Elements> elements) {this.elements = elements;}public Sequence(List<Elements> elements) {super();this.elements = elements;}public Sequence() {super();}}

public class Elements {private String name;private String type;private String value;private String minOccurs;public static String PROP_NAME = "name";public static String PROP_TYPE = "type";public static String PROP_VALUE = "value";public static String PROP_MIN_OCCURS = "minOccurs";public static String MUST_KEY_EVENTID = "EventID";public static String MUST_KEY_ACCEPTRESULT = "AcceptResult";public static String MUST_KEY_SOURCEIP = "SourceIP";public static String MUST_KEY_STARTTIME = "StartTime";public static String MUST_KEY_ENDTIME = "Endtime";public static String MUST_KEY_SEARCHRESULT = "SearchResult";public static String MUST_KEY_NOTIFYRESULT = "NotifyResult";public String getName() {return name;}@XmlAttributepublic void setName(String name) {this.name = name;}public String getType() {return type;}@XmlAttributepublic void setType(String type) {this.type = type;}public String getValue() {return value;}@XmlAttributepublic void setValue(String value) {this.value = value;}public String getMinOccurs() {return minOccurs;}@XmlAttributepublic void setMinOccurs(String minOccurs) {this.minOccurs = minOccurs;}public Elements(String name, String type, String value, String minOccurs) {super();this.name = name;this.type = type;this.value = value;this.minOccurs = minOccurs;}public Elements() {super();}public Elements(String name, String value) {super();this.name = name;this.value = value;}}

这个是具体的工具类实现：

public class XMLParser {public static String objConvertXml(Class<?> parserClass,Object obj){StringWriter writer = new StringWriter();try {JAXBContext jaxbContext = JAXBContext.newInstance(parserClass);  Marshaller marshaller = jaxbContext.createMarshaller();  marshaller.marshal(obj,writer);return writer.getBuffer().toString();} catch (JAXBException e) {e.printStackTrace();System.out.println("XML转换错误...!");} return null;}public static <T>T xmlConvertObj(Class<T> parserClass,String xmlStr){T req = null;try {JAXBContext jc = JAXBContext.newInstance(parserClass);Unmarshaller jaxbUnmarshaller = jc.createUnmarshaller();req = (T) jaxbUnmarshaller.unmarshal(new ByteArrayInputStream(xmlStr.getBytes()));} catch (JAXBException e) {e.printStackTrace();System.out.println("XML文件解析错误...!");}return req;}}

调用方法:

//读取xml文件并解析Schema schema = XMLParser.xmlConvertObj(Schema.class, xmlStr);

对象转换成XMLString

Schema schema = new Schema(new Element("UDRQueryResponse",new ComplexType(new Sequence(setElements()))));

 String xmlStr = XMLParser.objConvertXml(Schema.class,schema);
