我試圖解析XML文件來使用XStream的對象,但我得到這個異常:在線程Java的XStream的CannotResolveClassException
異常「主」 com.thoughtworks.xstream.mapper.CannotResolveClassException:服務器 在 com.thoughtworks.xstream.mapper.DefaultMapper.realClass(DefaultMapper.java:56) 在 com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper.java:30) 在 com.thoughtworks.xstream。 mapper.DynamicProxyMapper.realClass(DynamicProxyMapper.java:55) [...]
這裏是我的XML:
<servers>
<server>
<ip>10.196.113.27</ip>
</server>
<server>
<ip>10.196.113.31</ip>
</server>
</servers>
這裏是我的代碼:
public class ServerIP {
private String ip;
public String getIp() {
return ip;
}
public void setIp(String ip) {
this.ip = ip;
}
}
public class ServerHandler {
private String fileName = "servers.xml";
private String path = "J:\\workspace\\LOG730\\src\\Q3\\";
private XStream xstream = new XStream(new DomDriver());
public void readFromXML() {
try {
FileInputStream fis = new FileInputStream(path + fileName);
ServerIP server = (ServerIP) xstream.fromXML(fis, new ServerIP());
System.out.println("Host: " + server.getIp());
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
異常是由這個觸發:
ServerHandler serverHandler = new ServerHandler();
serverHandler.readFromXML();
使用註釋是一個很好的加在答案上 – Teg
