xml字符串转换成对象Jaxb技术

最外面的bean

	+ ", decLicenseDocu=" + decLicenseDocu + ", decFreeTxt=" + decFreeTxt + ", decSign=" + decSign + "]";
	}
	}
	对象的bean
	package com.sinotrans.ecustoms.pojo.cusdel;
	import java.util.Date;
	import javax.xml.bind.annotation.XmlAccessType;
	import javax.xml.bind.annotation.XmlAccessorType;
	import javax.xml.bind.annotation.XmlAttribute;

	import javax.xml.bind.annotation.XmlType;
	/**

	@XmlAccessorType(XmlAccessType.FIELD)
	@XmlType(propOrder = { "bonNo", "cusFie", "decBpNo", "decNo", "relId",
	"relManNo", "voyNo"})
	public class DecFreeTxt {
	@XmlElement(name = "BonNo",required = true)
	private String bonNo;
	@XmlElement(name = "CusFie",required = true)
	private String cusFie;

	return bonNo;
	}
	public void setBonNo(String bonNo) {
	this.bonNo = bonNo;
	}
	public String getCusFie() {
	return cusFie;
	}
	public void setCusFie(String cusFie) {
	this.cusFie = cusFie;
	}
	public String getDecBpNo() {
	return decBpNo;
	}
	public void setDecBpNo(String decBpNo) {
	this.decBpNo = decBpNo;
	}
	public String getDecNo() {
	return decNo;
	}
	public void setDecNo(String decNo) {
	this.decNo = decNo;
	}
	public String getRelId() {
	return relId;
	}
	public void setRelId(String relId) {
	this.relId = relId;
	}
	public String getRelManNo() {
	return relManNo;
	}
	public void setRelManNo(String relManNo) {
	this.relManNo = relManNo;
	}
	public String getVoyNo() {
	return voyNo;
	}

	}
	@Override
	public String toString() {
	return "DecFreeTxt [bonNo=" + bonNo + ", cusFie=" + cusFie + ", decBpNo=" + decBpNo + ", decNo=" + decNo
	+ ", relId=" + relId + ", relManNo=" + relManNo + ", voyNo=" + voyNo + "]";
	}
	}
	listBean 和bean 对象是一样的 只是最外层对象的 @XmlElementWrapper(name = "DecContainers") 是xml文件跟目录第一层@XmlElement(name = "Container") 是第二层
	package com.sinotrans.ecustoms.pojo.cusdel;
	import java.util.Date;
	import javax.xml.bind.annotation.XmlAccessType;
	import javax.xml.bind.annotation.XmlAccessorType;
	import javax.xml.bind.annotation.XmlAttribute;
	import javax.xml.bind.annotation.XmlElement;
	import javax.xml.bind.annotation.XmlRootElement;
	import javax.xml.bind.annotation.XmlType;
	/**
	* @author wpf
	* @create 2017-6-22
	*/
	@XmlAccessorType(XmlAccessType.FIELD)
	@XmlType(propOrder = { "containerId", "containerMd", "containerWt"})
	public class Container {
	@XmlElement(name = "ContainerId",required = true)
	private String containerId;
	@XmlElement(name = "ContainerMd",required = true)
	private String containerMd;
	@XmlElement(name = "ContainerWt",required = true)
	private String containerWt;
	public String getContainerId() {
	return containerId;
	}
	public void setContainerId(String containerId) {
	this.containerId = containerId;
	}
	public String getContainerMd() {
	return containerMd;
	}
	public void setContainerMd(String containerMd) {
	this.containerMd = containerMd;
	}
	public String getContainerWt() {
	return containerWt;
	}
	public void setContainerWt(String containerWt) {
	this.containerWt = containerWt;
	}
	@Override
	public String toString() {
	return "Container [containerId=" + containerId + ", containerMd=" + containerMd + ", containerWt=" + containerWt
	+ "]";
	}
	}
	最重要的是这个jaxb工具类
	package com.sinotrans.ecustoms.util.cusdel;
	import java.io.StringReader;
	import java.io.StringWriter;

	StringWriter writer = new StringWriter();

	result = writer.toString();
	} catch (Exception e) {
	e.printStackTrace();
	}
	return result;
	}
	/**

	@SuppressWarnings("unchecked")
	public static T converyToJavaBean(String xml, Class c) {

	t = (T) unmarshaller.unmarshal(new StringReader(xml));
	} catch (Exception e) {
	e.printStackTrace();
	}
	return t;
	}
	public static Object xml2java(String xml, Class clazz) {
	try {
	JAXBContext content = JAXBContext.newInstance(clazz);
	Unmarshaller m = content.createUnmarshaller();
	StringReader sr = new StringReader(xml);
	Object t = m.unmarshal(sr);
	return t;
	} catch (Exception e) {
	e.printStackTrace();
	}
	return null;
	}
	}
