JAVA使用xstream进行对象和xml互相转换

maven

com.thoughtworks.xstream
xstream
1.4.19

工具类
package com;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.io.xml.XmlFriendlyNameCoder;
import com.thoughtworks.xstream.io.xml.XppDriver;
import com.thoughtworks.xstream.security.AnyTypePermission;

public class XmlUtils {

public static <t> T xml2Bean(String xml, Class<t deep="6"> clazz) {<!-- -->
    XStream xstream = new XStream();
    // 开启类上的注解模式
    xstream.processAnnotations(clazz);
    xstream.addPermission(AnyTypePermission.ANY);
    return (T) xstream.fromXML(xml);
}

 
public static String bean2Xml(Object o) {<!-- -->
    // 处理下划线问题
    XStream xstream = new XStream(new XppDriver(new XmlFriendlyNameCoder("-_", "_")));
    // 开启类上的注解模式
    xstream.processAnnotations(o.getClass());
    return xstream.toXML(o);
}

}

User
package com.bean;

import com.thoughtworks.xstream.annotations.XStreamAlias;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
// 重命名
// 根路径不重命名对象转xml会转成带包的全路径 <com.bean.user></com.bean.user>
// 根路径不重命名xml转对象会报异常
@XStreamAlias(“user”)
public class User {

private String name;

private String sex;

private Integer age;

}
1.对象转xml
public static void main(String[] args) {
User user = new User(“张三”, “男”, 20);
// 对象转xml
String xml = XmlUtils.bean2Xml(user);
System.out.println(xml);
//
// 张三
// 男
// 20
//
}
2.xml转对象
public static void main(String[] args) {
String xml = “n” +
" 李四n" +
" 男n" +
" 22n" +
“”;
User user = XmlUtils.xml2Bean(xml, User.class);
System.out.println(user);
//User(name=李四, sex=男, age=22)
}
