用Xstream 来解析xml文本

用Xstream 来解析xml文本

文本内部还包含着既有属性又有值的这种情况 这边进行了toXml 和 toObj 的2种操作 目前我这边用的是注解来完成这一转换步骤

工具类

package com.xxx.common.util;

import com.xxx.xxx.base.vo.Data;
import com.xxx.xxx.base.vo.Field;
import com.xxx.xxx.base.vo.Service;
import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.DomDriver;
/**
 * XStream工具类 
 * @author Risk  
 * 2018年7月17日
 */
public class XStreamUtil {

    private static XStream xStream;

    static{
        xStream = new XStream(new DomDriver());
        xStream.processAnnotations(Service.class); //类加载 必须
        xStream.processAnnotations(Data.class);
        xStream.processAnnotations(Field.class);
    }

    //xml转java对象
    public static Object xmlToBean(String xml){
        return xStream.fromXML(xml);
    }

    //java对象转xml
    public static String beanToXml(Object obj){
        return "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + xStream.toXML(obj);
    }
}

pojo 简单的挑几个类来写

package com.xxx.xxx.base.vo;

import com.thoughtworks.xstream.annotations.XStreamAlias;

/** 
* @author 作者 Risk; 
* @version 创建时间：2018年7月17日 上午10:41:26 
* 类说明:  xml解析基础类
*/ 
@XStreamAlias("service") //该类是节点
public class Service {
    @XStreamAlias("sys-header")  //该字段换成指定字段  节点
    private SysHeader sysheader;
    @XStreamAlias("app-header")  
    private AppHeader appheader;
    @XStreamAlias("local-header")  
    private LocalHeader localheader;
    @XStreamAlias("body")  
    private Body body;
    public SysHeader getSysheader() {
        return sysheader;
    }
    public void setSysheader(SysHeader sysheader) {
        this.sysheader = sysheader;
    }
    public AppHeader getAppheader() {
        return appheader;
    }
    public void setAppheader(AppHeader appheader) {
        this.appheader = appheader;
    }
    public LocalHeader getLocalheader() {
        return localheader;
    }
    public void setLocalheader(LocalHeader localheader) {
        this.localheader = localheader;
    }
    public Body getBody() {
        return body;
    }
    public void setBody(Body body) {
        this.body = body;
    }

}

@XStreamAlias("field")
@XStreamConverter(value=ToAttributedValueConverter.class, strings={"text"})
//说明该字段解析成值
public class Field {
    @XStreamAsAttribute  //说明该字段解析成属性

    public String getText() {

    }

    public void setText(String text) {
        this.text = text;
    }

    }

    }

    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    } 

}
