创建第1层请求对象Bsxml

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;
import lombok.ToString;

import java.io.Serializable;

@Data
@ToString
@JacksonXmlRootElement(localName = "Bsxml") //XML根节点名称
public class Bsxml<T> implements Serializable {
    @JacksonXmlElementWrapper(localName = "MsgHeader")//反序列化XML参数的名称
    @JacksonXmlProperty(localName = "MsgHeader")//序列化XML参数的名称
    private MsgHeader msgHeader;//请求头对象
    @JacksonXmlElementWrapper(localName = "MsgBody")
    @JacksonXmlProperty(localName = "MsgBody")
    private T msgBody;//泛型消息体，我这里的泛型是可以去掉的，直接用MsgBody对象，这里只是为了模拟复杂对象。
}

创建第2层请求头对象MsgHeader

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;
import lombok.ToString;

import java.io.Serializable;

@Data
@ToString
@JacksonXmlRootElement(localName = "MsgHeader")
public class MsgHeader implements Serializable {
    @JacksonXmlElementWrapper(localName = "Organization")
    @JacksonXmlProperty(localName = "Organization")
    private String organization;
    @JacksonXmlElementWrapper(localName = "Sender")
    @JacksonXmlProperty(localName = "Sender")
    private String sender;
    @JacksonXmlElementWrapper(localName = "ServiceType")
    @JacksonXmlProperty(localName = "ServiceType")
    private String serviceType;
    @JacksonXmlElementWrapper(localName = "MsgType")
    @JacksonXmlProperty(localName = "MsgType")
    private String msgType;
    @JacksonXmlElementWrapper(localName = "MsgVersion")
    @JacksonXmlProperty(localName = "MsgVersion")
    private String msgVersion;
}

创建第2层请求头体MsgData

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;

/**
 * MsgBody对象就是Bsxml里面的泛型T
 */
@Data
@JacksonXmlRootElement(localName = "MsgBody")
public class MsgBody<D> {
    @JacksonXmlElementWrapper(localName = "Status")
    @JacksonXmlProperty(localName = "Status")
    private Boolean status;//状态
    @JacksonXmlElementWrapper(localName = "Code")
    @JacksonXmlProperty(localName = "Code")
    private Integer code;//成功状态码
    @JacksonXmlElementWrapper(localName = "ErrCode")
    @JacksonXmlProperty(localName = "ErrCode")
    private Integer errCode;//错误状态码
    @JacksonXmlElementWrapper(localName = "Detail")
    @JacksonXmlProperty(localName = "Detail")
    private String detail;//详细信息
    @JacksonXmlElementWrapper(localName = "Data")
    @JacksonXmlProperty(localName = "Data")
    private D data;//返回数据，泛型
}

创建第2层请求头体MsgData内层某个Data泛型对象

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlElementWrapper;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;
import lombok.ToString;

/**
 * LabReportAudit对象就是MsgBody里面的泛型 D
 */
@Data
@ToString
@JacksonXmlRootElement(localName = "Data")
public class LabReportAudit {
    @JacksonXmlElementWrapper(localName = "Name")
    private String name;
}

模拟Controller接参传参

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Slf4j
@RestController
@RequestMapping("test")
public class TestController {

    /**
     * 传xml转json,json转对象
     * @param bsxml Bsxml>
     */
    @PostMapping("xmlToObject")
    public void xmlToObject(@RequestBody Bsxml<MsgBody<LabReportAudit>> bsxml) throws JsonProcessingException {
        log.info("Bsxml转成实体后的信息：{}",bsxml);
        ObjectMapper objectMapper = new ObjectMapper();
        log.info("bsxml JSON：{}", objectMapper.writeValueAsString(bsxml));
    }

    /**
     * 传json转成对象，对象转xml
     * @param bsxml 实体类json
     */
    @PostMapping("objectToXml")
    public void objectToXml(@RequestBody Bsxml<MsgBody<LabReportAudit>> bsxml) throws JsonProcessingException {
        ObjectMapper objectMapper = new XmlMapper();
        String xmlString = objectMapper.writeValueAsString(bsxml);
        log.info("对象转xml：{}", xmlString);
    }

}
