加入pom

<dependency>

    <groupId>com.thoughtworks.xstream</groupId>

    <artifactId>xstream</artifactId>

    <version>1.4.3</version>

</dependency>

1. 最简单的使用方式

XStream xStream = new XStream();

//声明XStream注解来源

xStream.processAnnotations(FuiouResponse.class);

//xml 转bean

Object o = xStream.fromXML(xmlStr);

//bean 转xml

xStream.toXML(response)

1. 需要指明注解

/**

 * @author laoliangliang

 * @date 2018/11/6 17:00

 */

@XStreamAlias("ap")

public class FuiouResponse {

    @XStreamAlias("signature")

    private String signature;

    @XStreamAlias("plain")

    private Plain plain;

    public void setSignature(String signature) {

        this.signature = signature;

    }

    public String getSignature() {

        return signature;

    }

    public Plain getPlain() {

        return plain;

    }

    public void setPlain(Plain plain) {

        this.plain = plain;

    }

    public class Plain {

        @XStreamAlias("resp_code")

        private String respCode;

        @XStreamAlias("resp_desc")

        private String respDesc;

        public String getRespCode() {

            return respCode;

        }

        public void setRespCode(String respCode) {

            this.respCode = respCode;

        }

        public String getRespDesc() {

            return respDesc;

        }

        public void setRespDesc(String respDesc) {

            this.respDesc = respDesc;

        }

    }

}

和jpa类似，取个别名
