这是服务类。我通过从数据库中读取值来创建XML文件。代码正在使用另外三个pojo类。 Mt700，Header和Swift细节。 MT700是Header和swift细节的主要类。问题是我能够存储一次所有内容。使用一条记录生成文件时，我拥有多少行数据并不重要，它只有一个标题和一个快速细节。如何让这个工作循环？我想我必须使用列表，但我不知道如何使用它来使其工作。

这是MT700 POJO类。在这个课程中，我正在调用标题和swift细节pojo类。
@XmlRootElement(name = "MT700")
public class MT700 implements Serializable
{
/**
* serialVersionUID
*/
private static final long serialVersionUID = 1L;
private Header header;
private SwiftDetails swift700;
private String version = "1.0";
public Header getHeader()
{
return header;
}
@XmlElement(name = "Header")
public void setHeader(Header header)
{
this.header = header;
}
/**
* @return the swift700
*/
public SwiftDetails getSwift700()
{
return swift700;
}
@XmlElement(name = "Swift_Details_700")
public void setSwift700(SwiftDetails swift700)
{
this.swift700 = swift700;
}
public String getVersion()
{
return version;
}
@XmlAttribute(name = "Version")
public void setVersion(String version)
{
this.version = version;
}
}
这是Header类。我类似于这样有标签，这是很快的细节
@XmlRootElement(name = "Header")
@XmlType(propOrder = { "documentType", "messageType", "versionNo",
"revisionNo", "documentDate", "bankId", "custId", "custRefNo",
"bankRefNo" })
public class Header implements Serializable
{
private static final long serialVersionUID = 1L;
private String documentType;
private String messageType;
private String versionNo;
private String revisionNo;
private String documentDate;
private String bankId;
private String custId;
private String custRefNo;
private String bankRefNo;
我没有为此类添加getter和setter以使帖子看起来简单
答案 0 :(得分：0)
您正在创建一个MT700实例，然后在此循环中，每次循环时都会重新分配标题和swift字段：
MT700 mt700 = new MT700();
for (int i = 0; i < exportList.size(); i++) {
...
mt700.setHeader(header);
mt700.setSwift700(swift);
}
这意味着您输出的文档只包含数据库查询返回的最后一个标题/ swift。
您需要将这三个中的一个或多个放入某种列表中。您的MT700包含标题和雨燕的列表，或者您更希望拥有一个MT700列表，每个MT700都有一个标题和一个swift。
换句话说，您希望第四种类型是XML文档的实际根。该元素将为查询找到的每一行包含一个MT700元素。每个MT700元素都有一个header元素和一个swift元素。
因此，更具体地说，这就是你想要做的事情：
@XmlRootElement
class MT700s {
@XmlElement(name = "MT700")
private List<MT700> mt700s = new ArrayList<>();
public List<MT700> getMT700s() { return mt700s; }
// Etc.
}
MT700s mt700s = new MT700s();
for (int i = 0; i < exportList.size(); i++) {
MT700 mt700 = new MT700();
...
mt700.setHeader(header);
mt700.setSwift700(swift);
mt700s.getMT700s().add(mt700);
}
