使用JAXBContext轻松实现Java和xml的互相转换方式

JAXBContext实现Java和xml的互相转换 类文件注解：@XmlRootElement不可缺少

@XmlRootElementpublic class Man {private String name; private int age; public Student() {super(); } public Student(String name, int age) {super(); this.name = name; this.age = age; }public String getName() {return name; }public void setName(String name) {this.name = name; }public int getAge() {return age; }public void setAge(int age) {this.age = age; }}

Java 转换 Xml：
@Testpublic void testJava2Xml(){try {JAXBContext jc = JAXBContext.newInstance(Man.class); Marshaller ms = jc.createMarshaller(); Man man = new Man("man",100); ms.marshal(man, System.out); } catch (JAXBException e) {e.printStackTrace(); }}

Xml 转换 Java：
@Testpublic void testXml2Java() throws JAXBException{String xml = "100man"; JAXBContext jc = JAXBContext.newInstance(Man.class); Unmarshaller unmar = jc.createUnmarshaller(); Man man = (Man) unmar.unmarshal(new StringReader(xml)); System.out.println(man.getName()); }

JAXBContext 解析 xml 前提：
package com.sgcc.load.vo; import java.util.ArrayList; import java.util.List; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement(name = "gldxresult")@XmlAccessorType(XmlAccessType.FIELD)public class XmlAnalysis { // 泛化, 聚合 @XmlElement(name = "success") private String success; @XmlElement(name = "totalnum") private String totalnum; @XmlElement(name = "accounts")List accounts = new ArrayList<>(); public List getAccounts() {return accounts; } public void setAccounts(List accounts) {this.accounts = accounts; } public String getSuccess() {return success; } public void setSuccess(String success) {this.success = success; } public String getTotalnum() {return totalnum; } public void setTotalnum(String totalnum) {this.totalnum = totalnum; }}

package com.sgcc.load.vo; import java.util.ArrayList; import java.util.List; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; @SuppressWarnings("serial")@XmlAccessorType(XmlAccessType.FIELD)public class Accounts extends ArrayList{@XmlElement(name = "account")public List getAccount() {return this; }}

package com.sgcc.load.vo; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; @XmlAccessorType(XmlAccessType.FIELD)public class Account { @XmlElement(name = "seqid") private String seqid; @XmlElement(name = "dxid")private String dxid; @XmlElement(name = "compid")private String compid; @XmlElement(name = "rspcode")private String rspcode; @XmlElement(name = "code")private String code; @XmlElement(name = "name")private String name; public String getSeqid() {return seqid; } public void setSeqid(String seqid) {this.seqid = seqid; } public String getDxid() {return dxid; } public void setDxid(String dxid) {this.dxid = dxid; } public String getCompid() {return compid; } public void setCompid(String compid) {this.compid = compid; } public String getRspcode() {return rspcode; } public void setRspcode(String rspcode) {this.rspcode = rspcode; } public String getCode() {return code; } public void setCode(String code) {this.code = code; } public String getName() {return name; } public void setName(String name) {this.name = name; }}

测试：
package com.sgcc.load.test; import java.io.StringReader; import javax.xml.bind.JAXBContext; import javax.xml.bind.JAXBException; import javax.xml.bind.Unmarshaller; import com.sgcc.load.vo.Accounts; import com.sgcc.load.vo.XmlAnalysis; import groovyjarjarcommonscli.ParseException; public class Test { private static XmlAnalysis transToVOs(String webserviceMsg) throws JAXBException, ParseException {final StringReader reader = new StringReader(webserviceMsg); JAXBContext ctx=JAXBContext.newInstance(new XmlAnalysis().getClass()); Unmarshaller um=ctx.createUnmarshaller(); XmlAnalysis ds=(XmlAnalysis)um.unmarshal(reader); return ds; } public static void main(String[] args) {String xmlMsg = " \n01"+"hahaha11360051180603New0001值：00 没有匹配到分类"+"EHBSXPZYFDC000哈哈哈哈哈哈哈哈哈"; try{XmlAnalysis transToVOs = transToVOs(xmlMsg); for(int index = 0; index
