Java 组装复杂xml报文

近期在对接海关的订单出口报文，从网上找了挺多的案例，下面做一个记录

1、文件目录结构如下图所示

2、各文件代码

2.1、NameSpace类

/*** xml 命名空间*/
public class NameSpace {/*** order 订单节点*/public static final String NAMESPACE_CEB_URI = "http://www.chinaport.gov.cn/ceb";/*** dep终端节点报文*/public static final String NAMESPACE_DXP_URI = "http://www.chinaport.gov.cn/dxp";/*** xsi规范*/public static final String NAMESPACE_XSI_URI = "http://www.w3.org/2001/XMLSchema-instance";/*** 签名节点xml*/public static final String NAMESPACE_DS_URL = "http://www.w3.org/2000/09/xmldsig#";}

2.2、xml工作空间类 package-info.java

@XmlSchema(xmlns = {@XmlNs(prefix = "ceb", namespaceURI = NAMESPACE_CEB_URI),@XmlNs(prefix = "xsi", namespaceURI = NAMESPACE_XSI_URI)}
)
package com.ruoyi.online.request.order;import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlSchema;

2.3、订单出口报文CEB303Message

import lombok.Data;
import javax.xml.bind.annotation.*;/*** 海关出口订单报文*/
@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "CEB303Message" , namespace = NAMESPACE_CEB_URI)
public class CEB303Message {@XmlElement(name = "Order", namespace = NAMESPACE_CEB_URI)private Order order;@XmlAttribute(name = "guid")private String guid;@XmlAttribute(name = "version")private String version;@XmlElement(name = "BaseTransfer", namespace = NAMESPACE_CEB_URI)private BaseTransfer baseTransfer;//@XmlElement(name = "BaseSubscribe", namespace = NAMESPACE_CEB_URI)//private BaseSubscribe baseSubscribe;////@XmlElement(name = "ExtendMessage", namespace = NAMESPACE_CEB_URI)//private ExtendMessage extendMessage;
}

2.4、订单业务节点类

import lombok.Data;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.util.List;/*** 订单业务节点*/
@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "Order ", namespace = NAMESPACE_CEB_URI)
public class Order {@XmlElement(name = "OrderHead", namespace = NAMESPACE_CEB_URI)private OrderHead orderHead;@XmlElement(name = "OrderList", namespace = NAMESPACE_CEB_URI)private List orderList;}#订单头类import lombok.Data;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.math.BigDecimal;@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "OrderHead ", namespace = NAMESPACE_CEB_URI)
public class OrderHead {/*** 系统唯一序号 企业系统生成36位唯一序号 （英文字母大写）*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String guid;/*** 报送类型 企业报送类型。1-新增 2-变 更 3-删除。*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String appType;/*** 报送时间 格式:YYYYMMDDhhmmss。*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String appTime;/*** 报送状态  企业报送状态。1-暂存,2-申 报。填写2时,Signature节点必须 填写。*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String appStatus;/*** 订单类型*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String orderType;/*** 订单编号*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String orderNo;/*** 电商平台代码*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String ebpCode;/*** 电商平台名称*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String ebpName;/*** 电商* 企业代码*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String ebcCode;/*** 电商企业名称*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String ebcName;/*** 商品金额*/@XmlElement(namespace = NAMESPACE_CEB_URI)private BigDecimal goodsValue;/*** 运杂费*/@XmlElement(namespace = NAMESPACE_CEB_URI)private BigDecimal freight;/*** 币制*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String currency;/*** 备注*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String note;}#订单列表import lombok.Data;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import java.math.BigDecimal;@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "OrderList ", namespace = NAMESPACE_CEB_URI)
public class OrderList {/*** 序号 从1开始递增*/@XmlElement(namespace = NAMESPACE_CEB_URI)private Integer gnum;/*** 企业商品货号*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String itemNo;/*** 企业商品名称*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String itemName;/*** 企业商品描述*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String itemDescribe;/*** 条形码 否*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String barCode;/*** 计量单位*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String unit;/*** 币制*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String currency;/*** 数量*/@XmlElement(namespace = NAMESPACE_CEB_URI)private Integer qty;/*** 单价*/@XmlElement(namespace = NAMESPACE_CEB_URI)private BigDecimal price;/*** 总价*/@XmlElement(namespace = NAMESPACE_CEB_URI)private BigDecimal totalPrice;/*** 备注*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String note;
}

2.5、基础报文传输实体

import lombok.Data;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;@Data
@XmlAccessorType(XmlAccessType.FIELD)
@XmlRootElement(name = "BaseTransfer ", namespace = NAMESPACE_CEB_URI)
public class BaseTransfer {/*** 传输企业代码  报文传输的企业代码（需要与接入客户端的企 业身份一致）*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String copCode;/*** 传输企业名称*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String copName;/*** 报文传输模式  默认为DXP；指中国电子口岸数据交换平台*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String dxpMode;/*** 报文传输编号  向中国电子口岸数据中心申请数据交换平台 的用户编号*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String dxpId;/*** 备注*/@XmlElement(namespace = NAMESPACE_CEB_URI)private String note;
}

3、将出口订单实体转化为xml 报文工具类 JaxbUtils

import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
import java.io.StringReader;
import java.io.StringWriter;
import java.util.ArrayList;
import java.util.List;/*** java2xml 工具类*/
public class JaxbUtils {/*** JavaBean转换成xml* 默认编码UTF-8** @param obj* @return*/public static String convertToXml(Object obj) {return convertToXml(obj, "UTF-8");}/*** JavaBean转换成xml** @param obj* @param encoding* @return*/public static String convertToXml(Object obj, String encoding) {String result = null;try {JAXBContext context = JAXBContext.newInstance(obj.getClass());Marshaller marshaller = context.createMarshaller();//格式化xml格式marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);marshaller.setProperty(Marshaller.JAXB_ENCODING, encoding);//去掉生成xml的默认报文头marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);StringWriter writer = new StringWriter();// 由于不能优雅的去掉 standalone="yes" 所以只能去掉整个头部，然后手动插入一个符合条件的头部   该行为不优雅需要进行升级writer.append("" + "\n");marshaller.marshal(obj, writer);result = writer.toString();} catch (Exception e) {e.printStackTrace();}return result;}/*** xml转换成JavaBean** @param xml* @param c* @return*/@SuppressWarnings("unchecked")public static  T converyToJavaBean(String xml, Class c) {T t = null;try {JAXBContext context = JAXBContext.newInstance(c);Unmarshaller unmarshaller = context.createUnmarshaller();t = (T) unmarshaller.unmarshal(new StringReader(xml));} catch (Exception e) {e.printStackTrace();}return t;}
}
