Java转换为JSON首字母大写

最近调接口，入参JSON首字母需大写，步骤如下：

1.

package com.ceair.pojo;import java.io.Serializable;import java.util.List;import org.codehaus.jackson.annotate.JsonAutoDetect;import org.codehaus.jackson.annotate.JsonMethod;import org.codehaus.jackson.annotate.JsonProperty;import org.codehaus.jackson.map.annotate.JsonSerialize;@JsonAutoDetect(JsonMethod.FIELD)@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)public class FlightBookingRequest implements Serializable { /** *  */private static final long serialVersionUID = -7600859899586249635L;@JsonProperty("Account") private String account ; //B2T用户名@JsonProperty("AgentName") private String AgentName; //机构名称@JsonProperty("ContactName")private String ContactName; //联系人姓名@JsonProperty("ContactEmail")private String ContactEmail; //联系人邮箱@JsonProperty("ContactPhone")private String ContactPhone; //联系人电话@JsonProperty("PassengerPhone")private String PassengerPhone; //旅客联系电话@JsonProperty("ExtRefNo")private String ExtRefNo; //外部订单@JsonProperty("BookingChannel")private Integer BookingChannel; //预定方式@JsonProperty("FlightType")private String FlightType; //航班类型@JsonProperty("PnrCode")private String PnrCode; //旅客订座编号@JsonProperty("ListSegmentInfo")private List<SegmentInfo> ListSegmentInfo; //航段信息@JsonProperty("ListPassengerInfo")private List<PassengerInfo> ListPassengerInfo; //旅客信息public String getAccount() {return account;}public void setAccount(String account) {this.account = account;}public String getAgentName() {return AgentName;}public void setAgentName(String agentName) {AgentName = agentName;}public String getContactName() {return ContactName;}public void setContactName(String contactName) {ContactName = contactName;}public String getContactEmail() {return ContactEmail;}public void setContactEmail(String contactEmail) {ContactEmail = contactEmail;}public String getContactPhone() {return ContactPhone;}public void setContactPhone(String contactPhone) {ContactPhone = contactPhone;}public String getPassengerPhone() {return PassengerPhone;}public void setPassengerPhone(String passengerPhone) {PassengerPhone = passengerPhone;}public String getExtRefNo() {return ExtRefNo;}public void setExtRefNo(String extRefNo) {ExtRefNo = extRefNo;}public Integer getBookingChannel() {return BookingChannel;}public void setBookingChannel(Integer bookingChannel) {BookingChannel = bookingChannel;}public String getFlightType() {return FlightType;}public void setFlightType(String flightType) {FlightType = flightType;}public String getPnrCode() {return PnrCode;}public void setPnrCode(String pnrCode) {PnrCode = pnrCode;}public List<SegmentInfo> getListSegmentInfo() {return ListSegmentInfo;}public void setListSegmentInfo(List<SegmentInfo> listSegmentInfo) {ListSegmentInfo = listSegmentInfo;}public List<PassengerInfo> getListPassengerInfo() {return ListPassengerInfo;}public void setListPassengerInfo(List<PassengerInfo> listPassengerInfo) {ListPassengerInfo = listPassengerInfo;}}

注：@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)是Java转换为json时null不显示

//调用b2t预定接口ObjectMapper map = new ObjectMapper();String param = map.writeValueAsString(flight);
