BillHead billHead = new BillHead(); billHead.setCopListNo("12312524"); billHead.setCopNo("18"); try { XmlMapper xmlMapper = new XmlMapper(); xmlMapper.enable(SerializationFeature.INDENT_OUTPUT); String xml = xmlMapper.writeValueAsString(billHead); xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + xml; HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_XML); return new ResponseEntity<>(xml, headers, HttpStatus.OK); } catch (JsonProcessingException e) { return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR); } 将 return new ResponseEntity<>(xml, headers, HttpStatus.OK);转换为Object

如果要将返回的xml字符串转换为Object，可以使用XmlMapper的readValue方法，示例如下：

BillHead billHead = new BillHead();
billHead.setCopListNo("12312524");
billHead.setCopNo("18");

try {
    XmlMapper xmlMapper = new XmlMapper();
    xmlMapper.enable(SerializationFeature.INDENT_OUTPUT);
    String xml = xmlMapper.writeValueAsString(billHead);
    xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + xml;

    // Convert XML string to object
    BillHead parsedBillHead = xmlMapper.readValue(xml, BillHead.class);

    return parsedBillHead;
} catch (JsonProcessingException e) {
    return null;
}

这里假设你的BillHead类是一个可以被序列化和反序列化的Java类。注意读取XML时需要指定要转换的目标类。

BillHead billHead = new BillHead(); billHead.setCopListNo("12312524"); billHead.setCopNo("18"); try { XmlMapper xmlMapper = new XmlMapper(); xmlMapper.enable(SerializationFeature.INDENT_OUTPUT); String xml = xmlMapper.writeValueAsString(billHead); xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n" + xml; // Convert XML string to object BillHead parsedBillHead = xmlMapper.readValue(xml, BillHead.class); return parsedBillHead; } catch (JsonProcessingException e) { return null; } 根据以上代码创建相应的BillHead类

可以根据以下代码创建相应的BillHead类：

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;

@JacksonXmlRootElement(localName = "BillHead")
public class BillHead {
    @JacksonXmlProperty(localName = "copListNo")
    private String copListNo;
    @JacksonXmlProperty(localName = "copNo")
    private String copNo;

    public String getCopListNo() {
        return copListNo;
    }

    public void setCopListNo(String copListNo) {
        this.copListNo = copListNo;
    }

    public String getCopNo() {
        return copNo;
    }

    public void setCopNo(String copNo) {
        this.copNo = copNo;
    }
}

在这个类中，使用了`@JacksonXmlRootElement`注释来指定该类是一个XML根元素。使用`@JacksonXmlProperty`注释来指定XML元素的名称，以及将Java属性映射到这些XML元素。在getter和setter方法中，可以访问这些属性的值。

@JacksonXmlRootElement(localName = "BillHead") public class BillHead { //企业内部编号 @JacksonXmlProperty(localName = "CopListNo") private String CopListNo; //企业编号 @JacksonXmlProperty(localName = "CopNo") private String CopNo; } 获得Http客户端(可以理解为:你得先有一个浏览器;注意:实际上HttpClient与浏览器是不一样的) CloseableHttpClient httpClient = HttpClientBuilder.create().build(); // 创建Post请求 HttpPost httpPost = new HttpPost(WcsHttpUtil.httpUtil.agvs); // 设置ContentType(注:如果只是传普通参数的话,ContentType不一定非要用application/json) httpPost.setHeader("Content-Type", "application/json;charset=utf8"); // 响应模型 CloseableHttpResponse response = null; String jsonString = JSON.toJSONString(object); StringEntity entity = new StringEntity(jsonString, "UTF-8"); // post请求是将参数放在请求体里面传过去的;这里将entity放入post请求体中 httpPost.setEntity(entity); // 由客户端执行(发送)Post请求 response = httpClient.execute(httpPost); // 从响应模型中获取响应实体 HttpEntity responseEntity = response.getEntity(); 使用BillHead接收

可以使用以下代码来接收响应：

CloseableHttpResponse response = null;
try {
    response = httpClient.execute(httpPost);
    HttpEntity responseEntity = response.getEntity();
    if (responseEntity != null) {
        String responseString = EntityUtils.toString(responseEntity, "UTF-8");
        BillHead billHead = JSON.parseObject(responseString, BillHead.class);
        // 处理返回的BillHead对象
    }
} finally {
    if (response != null) {
        response.close();
    }
}

其中，`responseString` 是从响应实体中获取到的字符串，然后使用 `JSON.parseObject()` 方法将其转换为 `BillHead` 对象。最后你可以在使用 `billHead` 对象进行处理。
