从Java创建XML文件jaxB

这是服务类。我通过读取数据库中的值来创建XML文件。代码使用三个pojo类。 Mt700，Header和Swift细节。 MT700是Header和快速细节的主要类。问题是我能够一次存储所有内容。使用一条记录生成文件时，具有多少行数据并不重要，它只有一个标题和一个快速详细信息。我怎样才能使这项工作循环？我想我必须使用列表，但我不知道如何使用它来使其工作。从Java创建XML文件jaxB

      } 
      return mt700; 
     }

这是MT700 POJO类。在这个类中，我调用了头文件和快速详细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; 
     } 

    }

这是标头类。类似的I类喜欢这其中有标签，那就是迅速细节

@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;

我不添加getter和setter该类使后看起来简单

你正在创建一个MT700实例，然后在这个循环中，你是通过循环重新分配头和迅速的领域，每次：

MT700 mt700 = new MT700(); 
for (int i = 0; i < exportList.size(); i++) { 
    ... 
    mt700.setHeader(header); 
    mt700.setSwift700(swift); 
}

这意味着你在输出文件只包含从数据库查询返回的最后一个头/快捷。

您需要将这三个中的一个或多个放入某种列表中。无论是你的MT700包含一个标题和swift的列表，或者更可能你想要一个MT700列表，每个都有一个标题和一个swift。

换句话说，你想要第四种类型，它将是你的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元件都有一个标题元素和一个swift元素。

所以，更具体地说，这里是你想做的事：

@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); 
}

我这样做，现在的文件越来越产生。我有数据，但它不是XML。我创建了LIst。但是，在JAXB我得到错误。似乎JAXB不接受列表.... – Sam

我正是在这种情况。我该怎么办？ http://stackoverflow.com/questions/12139996/how-to-convert-arraylistobject-to-a-xml-using-jaxb – Sam
