标签 java json xml jackson fasterxml

我正在尝试将 xml 响应转换为 java 对象，但解析时出现错误。我尝试了所有选项但没有成功。 xml 可以有多个标签。 该错误基本上是在将 xml 标签转换为数组对象时出现的。 我的类(class)是:

将 xml 解析为类的代码是:

public static AHBESBFetchAllAccountsFullResponse parseXMLResponseForGetAllAccounts(byte[] response)
            throws JsonParseException, JsonMappingException, IOException {
        ObjectMapper objectMapper;
        AHBESBFetchAllAccountsFullResponse getAllAccountsResponse = null;
        System.err.println(response);
        objectMapper = new XmlMapper();
        getAllAccountsResponse = objectMapper.readValue(StringUtils.toEncodedString(response, StandardCharsets.UTF_8),
                AHBESBFetchAllAccountsFullResponse.class);
        System.err.println(getAllAccountsResponse.getResponseBody().getCustomerAccountsReply().getCustomerNumber());
        return getAllAccountsResponse;
    }

响应 xml 是:

最佳答案

看起来 AccountSummaryReply 数组已在您的 XML 中展开。它通常看起来像:

<AccountSummaryReplies>
   <AccountSummaryReply>
      <AccountNumber>545545453</AccountNumber>
   </AccountSummaryReply>
   <AccountSummaryReply>
      <AccountNumber>545545454</AccountNumber>
   </AccountSummaryReply>
</AccountSummaryReplies>

您必须指定数组在 XML 中显示为未包装:

@JacksonXmlElementWrapper(useWrapping = false)
@JacksonXmlProperty(localName = "AccountSummaryReply")
private AccountSummaryReply[] AccountSummaryReply;

作为旁注，请考虑使用以下方式配置您的 XmlMapper:

mapper.setPropertyNamingStrategy(PropertyNamingStrategy.UPPER_CAMEL_CASE);

这意味着 XML 中的所有属性名称都以大写字母开头，并允许跳过所有 @JacksonXmlProperty(localName = ) 注释
