JAXB的应用
主要是注意JAXB的注解的使用@XmlRootElement(根节点)、@XmlElement(子节点)、@XmlAttribute(节点属性)
如解析如下xml文档：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <insuredInfo> <insuredName>hehongbo</insuredName> <insuredIdentifyType>1</insuredIdentifyType> <insuredIdentifyNumber>430611198307215013</insuredIdentifyNumber> <insuredMobile>13243764322</insuredMobile> <insuredEmail>[email protected]</insuredEmail> </insuredInfo>
需要转换的java对象：
package com.cheyooh.service.dal.db.dto.api.dadi;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "insuredInfo")
public class InsuredInfo {
private String insuredName;
private String insuredIdentifyType;
private String insuredIdentifyNumber;
private String insuredMobile;
private String insuredEmail;
@XmlElement(name = "insuredName")
public String getInsuredName() {
return insuredName;
}
public void setInsuredName(String insuredName) {
this.insuredName = insuredName;
}
@XmlElement(name = "insuredIdentifyType")
public String getInsuredIdentifyType() {
return insuredIdentifyType;
}
public void setInsuredIdentifyType(String insuredIdentifyType) {
this.insuredIdentifyType = insuredIdentifyType;
}
@XmlElement(name = "insuredIdentifyNumber")
public String getInsuredIdentifyNumber() {
return insuredIdentifyNumber;
}
public void setInsuredIdentifyNumber(String insuredIdentifyNumber) {
this.insuredIdentifyNumber = insuredIdentifyNumber;
}
@XmlElement(name = "insuredMobile")
public String getInsuredMobile() {
return insuredMobile;
}
public void setInsuredMobile(String insuredMobile) {
this.insuredMobile = insuredMobile;
}
@XmlElement(name = "insuredEmail")
public String getInsuredEmail() {
return insuredEmail;
}
public void setInsuredEmail(String insuredEmail) {
this.insuredEmail = insuredEmail;
}
}
如果再一个xml文档子节点下还有一个子节点，如何映射呢？
对于这个问题，需要再java对象中什么的时候，子节点属性不能只是简单的java对象，而是要声明为List对象，如：private List<Request> request;
xml：
<?xml version="1.0" encoding="GBK"?> <message finishTime=”2011-12-25 12:00:00”> <!--from里为sellerId，需要与GET请求里所传参数保持一致 --> <request func=" car_info_sync" return=”true” from=”*****”> <content> <orderInfo> <name>用户名称</name> <mobile>手机号码</mobile> <email>电子邮件地址</email> <carLicence>车牌号</carLicence> <!—车辆行驶城市代码 六位 --> <cityCode>xxxxxx</cityCode> <!—车辆登记日期，到日或者到月 --> <registerDate>YYYY-MM-DD 或者 YYYY-MM</registerDate> <!—商业险生效日期 --> <bizBeginDate>YYYY-MM-DD</bizBeginDate> <!—交强险生效日期 --> <forBeginDate>YYYY-MM-DD</forBeginDate> <utmsn>123456</utmsn> </orderInfo> </content> </request> </message>
java对象：
package com.cheyooh.service.dal.db.dto.api.dadi;
import java.util.List;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "message")
public class Message {
private String finishTime;
private List<Request> request;
@XmlAttribute(name = "finishTime")
public String getFinishTime() {
return finishTime;
}
public void setFinishTime(String finishTime) {
this.finishTime = finishTime;
}
@XmlElement(name = "request")
public List<Request> getRequest() {
return request;
}
public void setRequest(List<Request> request) {
this.request = request;
}
@Override
public String toString() {
return "Message [finishTime=" + finishTime + ", request=" + request
+ "]";
}
}
这里可以看到，message节点中的request子节点映射为list集合，但是get方法中是注解仍然是@XmlElement。
request对象的声明：
package com.cheyooh.service.dal.db.dto.api.dadi;
import java.util.List;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "request")
public class Request {
private String func;
private String returnAttribute;
private String from;
private List<Content> content;
@XmlAttribute(name = "func")
public String getFunc() {
return func;
}
public void setFunc(String func) {
this.func = func;
}
@XmlElement(name = "content")
public List<Content> getContent() {
return content;
}
public void setContent(List<Content> content) {
this.content = content;
}
@XmlAttribute(name = "return")
public String getReturnAttribute() {
return returnAttribute;
}
public void setReturnAttribute(String returnAttribute) {
this.returnAttribute = returnAttribute;
}
@XmlAttribute(name = "from")
public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
}
request节点中的content子节点对象：
package com.cheyooh.service.dal.db.dto.api.dadi;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "content")
public class Content {
private List<OrderInfo> orderInfo;
@XmlElement(name = "orderInfo")
public List<OrderInfo> getOrderInfo() {
return orderInfo;
}
public void setOrderInfo(List<OrderInfo> orderInfo) {
this.orderInfo = orderInfo;
}
}
最后是orderInfo节点的对象映射：
package com.cheyooh.service.dal.db.dto.api.dadi;
import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement(name = "orderInfo")
public class OrderInfo {
private String chanceCreateTime; //商机进入时间
private String startDate; //起保日期
private String insuranceApplicantNo; //投保单号
private Double premium; //总保费
private String insuranceType; //投保单类型
private String utmsn; //合作方订单号
private String paymentNo; //支付申请号
private String paymentTime; //支付申请时间
private String policyNo; //保单号
private String effectdate; //保单生效时间
private List<Commercial> commercial; //商业险信息
private List<Compulsory> compulsory; //交强险信息
private List<VehicleInfo> vehicleInfo; //车辆信息
private List<ApplicantInfo> applicantInfo; //投保人信息
private List<InsuredInfo> insuredInfo; //被保人信息
private List<DistributionInfo> distributionInfo; //配送信息
private String name;// 姓名
private String mobile;// 手机号
private String email;// 邮箱
private String carLicence;// 车牌号
private String cityCode;
private String registerDate;
private String bizBeginDate;
private String forBeginDate;
@XmlElement(name = "name")

}
@XmlElement(name = "insuredInfo")
public List<InsuredInfo> getInsuredInfo() {
return insuredInfo;
}
public void setInsuredInfo(List<InsuredInfo> insuredInfo) {
this.insuredInfo = insuredInfo;
}
@XmlElement(name = "distributionInfo")
public List<DistributionInfo> getDistributionInfo() {
return distributionInfo;
}
public void setDistributionInfo(List<DistributionInfo> distributionInfo) {
this.distributionInfo = distributionInfo;
}
@XmlElement(name = "chanceCreateTime")
public String getChanceCreateTime() {
return chanceCreateTime;
}
public void setChanceCreateTime(String chanceCreateTime) {
this.chanceCreateTime = chanceCreateTime;
}
@XmlElement(name = "startDate")
public String getStartDate() {
return startDate;
}
public void setStartDate(String startDate) {

return insuranceApplicantNo;
}
public void setInsuranceApplicantNo(String insuranceApplicantNo) {
this.insuranceApplicantNo = insuranceApplicantNo;
}
@XmlElement(name = "premium")
public Double getPremium() {
return premium;
}
public void setPremium(Double premium) {
this.premium = premium;
}
@XmlElement(name = "insuranceType")
public String getInsuranceType() {
return insuranceType;
}
public void setInsuranceType(String insuranceType) {
this.insuranceType = insuranceType;
}
@XmlElement(name = "utmsn")
public String getUtmsn() {
return utmsn;
}
public void setUtmsn(String utmsn) {
this.utmsn = utmsn;
}
@XmlElement(name = "commercial")
public List<Commercial> getCommercial() {
return commercial;
}
public void setCommercial(List<Commercial> commercial) {
this.commercial = commercial;
}
@XmlElement(name = "compulsory")
public List<Compulsory> getCompulsory() {
return compulsory;
}
public void setCompulsory(List<Compulsory> compulsory) {
this.compulsory = compulsory;
}
@XmlElement(name = "vehicleInfo")
public List<VehicleInfo> getVehicleInfo() {
return vehicleInfo;
}
public void setVehicleInfo(List<VehicleInfo> vehicleInfo) {
this.vehicleInfo = vehicleInfo;
}
@XmlElement(name = "paymentNo")
public String getPaymentNo() {
return paymentNo;
}
public void setPaymentNo(String paymentNo) {
this.paymentNo = paymentNo;
}
@XmlElement(name = "paymentTime")
public String getPaymentTime() {
return paymentTime;
}
public void setPaymentTime(String paymentTime) {
this.paymentTime = paymentTime;
}
@XmlElement(name = "policyNo")
public String getPolicyNo() {
return policyNo;
}
public void setPolicyNo(String policyNo) {

}
@XmlElement(name = "effectdate")
public String getEffectdate() {

}
}
至此，JAXB就完成了对复杂XML文档的映射解析，除了需要注意子节点集合映射为list集合之外，注解的关键字必须要正确，否则取不到内容。
