SpringBoot接收Xml格式参数并转换为POJO对象

1. 所需JavaBean

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = {"head","body" })  // 子节点名称
@XmlRootElement(name = "xml")   // 当前节点名称
@Data
public class XmlRemoteDto {

    // 接收head标签
    private Head head;
	
    // 接收body标签
    private Body body;
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "body")
@XmlType(name = "userInfo")
@Data
public class Body {

    @XmlElement(name = "userInfo")
    private UserInfo userInfo;
}

@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "head")  // 当前节点名称
@Data
public class Head {

    @XmlElement(name = "token")  // 子节点名称
    private String token;
}

// 业务所需的参数封装类
@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "userInfo")
public class UserInfo {

    @XmlElement(name = "name")
    private String name;

    @XmlElement(name = "password")
    private String password;

    @XmlElement(name = "email")
    private String email;
}

2. XML解析工具类

@Slf4j
public class XmlParseUtil {

    /**
     * 解析XMl内容，转换为POJO类
     *
     * @param clazz 要解析的对象
     * @param xml 解析的xml字符串
     * @return 解析完成的对象
     */
    public static Object convertXmlStrToObject(Class clazz, String xml) {
        Object xmlObject = null;
        try {
            JAXBContext context = JAXBContext.newInstance(clazz);
            // 进行将Xml转成对象的核心接口
            Unmarshaller unmarshaller = context.createUnmarshaller();
            StringReader sr = new StringReader(xml);
             xmlObject = unmarshaller.unmarshal(sr);
        } catch (Exception e) {
            log.error("convert xmlStr to object error, msg <{}>",e.getMessage(),e);
        }
        return xmlObject;
    }
}

3. 处理接口

@PostMapping("/convertXmlToObject")
public String fzpAgencyInfo(@RequestBody String paramXml) {
    XmlRemoteDto xmlRemoteDto = (XmlRemoteDto) XmlParseUtil.convertXmlStrToObject(XmlRemoteDto.class, paramXml);
    Body body = xmlRemoteDto.getBody();
    UserInfo userInfo = body.getUserInfo();
    return userInfo.toString();
}

4. 测试

<xml>
    <head>
        <token>1234</token>
    </head>
    <body>
        <userInfo>
            <name>admin</name>
            <password>123456</password>
            <email>123@qq.com</email>
        </userInfo>
    </body>
</xml>
