1,要解析的xml文件文件
xml="\n" + " ";\n" + " \n" + "1 \n" + "burn \n" + "1.0 \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "\n" + " \n" + "2 \n" + "burn2 \n" + "2.1 \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "\n" + " \n" + "3 \n" + "burn3 \n" + "3.2 \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "\n" + " \n" + "10.5 \n" + "hhhhhhhh \n" + "
2,新建xml文件对应的封装类
/** * xml数据对应的封装类(注意实体类和xml数据的对应关系,所有标签都得对应) */ @XStreamAlias("apps")//配置标签别名 public class AppBean { @XStreamImplicit//忽略集合根节点 private Listapp_list; //必须有无参构造方法 public AppBean() { } public AppBean(List app_list) { this.app_list = app_list; } public List getApp_list() { return app_list; } public void setApp_list(List app_list) { this.app_list = app_list; } @XStreamAlias("app") public static class App{ private long id; private String name; private String version; @XStreamImplicit private List infor_list; public App() { } public App(long id, List infor_list, String name, String version) { this.id = id; this.infor_list = infor_list; this.name = name; this.version = version; } public long getId() { return id; } public void setId(long id) { this.id = id; } public List getInfor_list() { return infor_list; } public void setInfor_list(List infor_list) { this.infor_list = infor_list; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } @XStreamAlias("info") public static class Infor{ private String message; private double size; public Infor() { } public Infor(String message, double size) { this.message = message; this.size = size; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } public double getSize() { return size; } public void setSize(double size) { this.size = size; } } } }
3,开始xml解析
XStream xStream=new XStream(); xStream.processAnnotations(AppBean.class);//声明使用注解的类 AppBean ab2= (AppBean) xStream.fromXML(xml);//xml-->Bean,只能解析为对象,不能解析为集合 String xml=xStream.toXML(AppBean.class)//Bean-->xml
