JAXBContext实现Java与xml转换 使用JAXBContext轻松实现Java和xml的互相转换方式
它山之石,可以攻玉 人气:0想了解使用JAXBContext轻松实现Java和xml的互相转换方式的相关内容吗,它山之石,可以攻玉在本文为您仔细讲解JAXBContext实现Java与xml转换的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:使用JAXBContext,Java和xml互相转换,下面大家一起来学习吧。
JAXBContext实现Java和xml的互相转换
类文件注解:@XmlRootElement不可缺少
<span style="font-size:14px;">@XmlRootElement public 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; } } </span>
Java 转换 Xml:
@Test public 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:
@Test public void testXml2Java() throws JAXBException{ String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><Man><age>100</age><name>man</name></Man>"; 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> accounts = new ArrayList<>(); public List<Accounts> getAccounts() { return accounts; } public void setAccounts(List<Accounts> 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<Account>{ @XmlElement(name = "account") public List<Account> 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 = "<?xml version=\"1.0\" encoding=\"GBK\"?> \n<gldxresult><success>0</success><totalnum>1</totalnum>"+ "<accounts><yzy>hahaha</yzy><account><seqid></seqid><dxid>1136005118</dxid><compid>0603</compid><rspcode>New0001</rspcode><rspmsg>值:00 没有匹配到分类</rspmsg>"+ "<code>EHBSXPZYFDC000</code><name>哈哈哈哈哈哈哈哈哈</name></account></accounts></gldxresult>"; try{ XmlAnalysis transToVOs = transToVOs(xmlMsg); for(int index = 0;index<transToVOs.getAccounts().get(0).getAccount().size();index++){ System.out.println(transToVOs.getAccounts().get(0).getAccount().get(index).getName()); } }catch(Exception e){ e.printStackTrace(); } } }
以上为个人经验,希望能给大家一个参考,也希望大家多多支持。
