xstream如何将java对象转化成有cdata的xml

xstream如何将java对象转化成有cdata的xml

实体类要加注解
实体类要加注解
@XStreamAlias("msg")
public class Msg implements Serializable {

    private static final long serialVersionUID = 3196422897798539811L;
    
    @XStreamAsAttribute
    private String toUid;
    @XStreamAsAttribute
    private String fromUid;
    @XStreamAsAttribute
    private String flag;
    @XStreamAsAttribute
    private String time;
    @XStreamAlias("content")
    private String content;
    @XStreamAlias("user")
    private String user;
    //省略geter、seter
}
然后写个工具类
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;

public class SerializeXmlUtil {

    
    public static String serializeToXml(Object obj) {
        //XStream xstream = new XStream();
        //直接用jaxp dom来解释
        //XStream xstream=new XStream(new DomDriver());
        //指定编码解析器,直接用jaxp dom来解释
        XStream xstream=new XStream(new DomDriver("utf-8"));
        //如果没有这句，xml中的根元素会是<包.类名>
        //或者说：注解根本就没生效，所以的元素名就是类的属性
        xstream.processAnnotations(obj.getClass());
        StringBuffer xmlstrbuf = new StringBuffer();
        xmlstrbuf.append("");
        xmlstrbuf.append("
");
        xmlstrbuf.append(xstream.toXML(obj));
        return xmlstrbuf.toString();
    }
    
    
    public static  T deSerizalizeFromXml(String xmlstr, Class cls) throws Exception {
        //注意：不是new Xstream();否则报错：java.lang.NoClassDefFoundError:
        //org/xmlpull/v1/XmlPullParserFactory
        XStream xstream = new XStream(new DomDriver());
        xstream.processAnnotations(cls);
        T obj = (T) xstream.fromXML(xmlstr);
        return obj;
    }
}

网上很多。百度。

private static XStream xstream = new XStream(new XppDriver() {
    public HierarchicalStreamWriter createWriter(Writer out) {
        return new PrettyPrintWriter(out) {
            // 对所有xml节点的转换都增加CDATA标记
            boolean cdata = true;
            @SuppressWarnings("unchecked")
            public void startNode(String name, Class clazz) {
                super.startNode(name, clazz);
            }
            protected void writeText(QuickWriter writer, String text) {
                if (cdata) {
                    writer.write("                    writer.write(text);
                    writer.write("]]>");
                } else {
                    writer.write(text);
                }
            }
        };
    }
});
