案例敏感的pojo对json映射杂种

Question

将对象写入JSON时，如何保留键的原始情况？

POJO级：

public class LeadRequest
{
    private String AccountName;
    private String AccountAlias;
    private String BPID;
    private String CustomerType;
    private String Email;
    private String LocationType;
    private String APRID;
    private String APRDistributorName;
    private String EngagedwithRAOrDistributor;

    public String getBPID()
    {
        return BPID;
    }
    public void setBPID(final String bPID)
    {
        BPID = bPID;
    }
    public String getEngagedwithRAOrDistributor()
    {
        return EngagedwithRAOrDistributor;
    }
    public void setEngagedwithRAOrDistributor(final String engagedwithRAOrDistributor)
    {
        EngagedwithRAOrDistributor = engagedwithRAOrDistributor;
    }
}

Service-class：

public void submitLeadRequest(final LeadRequest lead)
{
    try
    {
        final String endPoint = Config.getParameter(ServicesConstants.API_URL);
        final HttpPost request = new HttpPost(endPoint);
        request.addHeader(ServicesConstants.CONTENT_TYPE, ServicesConstants.APPLICATION_JSON);
        request.addHeader(ServicesConstants.CLIENT_ID, Config.getParameter(ServicesConstants.CLIENT_ID));
        request.addHeader(ServicesConstants.CLIENT_SECRET, Config.getParameter(ServicesConstants.CLIENT_SECRET));

        final ObjectMapper mapper = new ObjectMapper();
        final String jsonInString = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(lead);
        final StringEntity entity = new StringEntity(jsonString);
        request.setEntity(entity);
        final RequestConfig requestConfig = getRequestConfig(API_TIMEOUT_LONG);
        final CloseableHttpClient client = HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).build();
        CloseableHttpResponse response = client.execute(request);      
    }
}

当前生成的邮政请求是：

{
  "accountAlias" : "No Account Alias",
  "accountName" : "REI AUTOMATION INC",
  "customerType" : "OEM",
  "aprid" : "002",
  "bpid" : "0099105850",
  "locationType" : "Research & Development",
  "email" : "[email protected]",
  "engagedwithRAOrDistributor" : "",
  "aprdistributorName" : "002-CED Royal Industrial Elec"
}

但是，邮政请求未能给予HTTP/1.1 500服务器错误，因为在请求JSON中的案例敏感键json中的系统被称为系统

，因此所需的请求json是：

如果您使用com.fasterxml.jackson.databind.objectMapper，则可以使用com.fasterxml.jackson.jackson.jsonproperty例如：

@JsonProperty("AccountName")
private String AccountName;

或您可以“告诉”映射器使用字段而不是制作最终JSON的getters。为了这样做，您可以按以下方式配置映射器类：

mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.NONE);
mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
