蓝色网站,wordpress能赚钱,接入网站备案要多久,番禺人才网招聘网JAVA8 可以使用标准的 DOM 方式的 API 来编写代码解析 XML 文件#xff0c;无需引入第三方依赖。下面是两个测试用的 XML 文件#xff1a;
test.xml
allDatapan attr1a attr2b1/pantilt2/tiltzoom无需引入第三方依赖。下面是两个测试用的 XML 文件
test.xml
allDatapan attr1a attr2b1/pantilt2/tiltzoom3/zoomlistitemitem0/itemitemitem1/itemitemitem2/item/listuser-listusername张三/namegender男/gender/userusername高启兰/namegender女/gender/user/user-list
/allDatatest2.xml
allDatapan attr1a 1/panzoom3/zoomlistitemitem0/itemitemitem1/itemitemitem2/item/list
/allData负责接收所有信息的 AllDataDTO.java
package zhangchao;
import java.util.ArrayList;
import java.util.List;public class AllDataDTO {private Integer pan;private Integer tilt;private Integer zoom;private ListString list new ArrayList();private String panAttr1;private String panAttr2;private ListAllDataUserDTO userList new ArrayList();///// setters/getters///Overridepublic String toString() {final StringBuffer sb new StringBuffer(AllDataDTO{);sb.append(pan).append(pan);sb.append(, tilt).append(tilt);sb.append(, zoom).append(zoom);sb.append(, list).append(list);sb.append(, panAttr1).append(panAttr1).append(\);sb.append(, panAttr2).append(panAttr2).append(\);sb.append(, userList).append(userList);sb.append(});return sb.toString();}public ListAllDataUserDTO getUserList() {return userList;}public void setUserList(ListAllDataUserDTO userList) {this.userList userList;}public ListString getList() {return list;}public void setList(ListString list) {this.list list;}public String getPanAttr1() {return panAttr1;}public void setPanAttr1(String panAttr1) {this.panAttr1 panAttr1;}public String getPanAttr2() {return panAttr2;}public void setPanAttr2(String panAttr2) {this.panAttr2 panAttr2;}public Integer getPan() {return pan;}public void setPan(Integer pan) {this.pan pan;}public Integer getTilt() {return tilt;}public void setTilt(Integer tilt) {this.tilt tilt;}public Integer getZoom() {return zoom;}public void setZoom(Integer zoom) {this.zoom zoom;}
}
负责接收用户信息的 AllDataUserDTO.java
package zhangchao;public class AllDataUserDTO {private String name;private String gender;Overridepublic String toString() {final StringBuffer sb new StringBuffer(AllDataUserDTO{);sb.append(name).append(name).append(\);sb.append(, gender).append(gender).append(\);sb.append(});return sb.toString();}///// setters/getters///public String getName() {return name;}public void setName(String name) {this.name name;}public String getGender() {return gender;}public void setGender(String gender) {this.gender gender;}
}处理 XML 文件的工具类XmlUtils.java

}用于测试效果的类 Main.java
package zhangchao;public class Main {public static void main(String[] args) {AllDataDTO allDataDTO XmlUtils.parseXml(E:\\ws\\zc\\Java8Xml\\src\\main\\resources\\TestFile\\ test.xml);AllDataDTO allDataDTO2 XmlUtils.parseXml(E:\\ws\\zc\\Java8Xml\\src\\main\\resources\\TestFile\\ test2.xml);System.out.println(allDataDTO);System.out.println(allDataDTO2);}
}输出结果
AllDataDTO{pan1, tilt2, zoom3, list[item0, item1, item2], panAttr1a, panAttr2b, userList[AllDataUserDTO{name张三, gender男}, AllDataUserDTO{name高启兰, gender女}]}
AllDataDTO{pan1, tiltnull, zoom3, list[item0, item1, item2], panAttr1a, panAttr2null, userList[]}
