还有 5 个类：目录、CD、专辑、艺术家、国家/地区、注册表

如何获取带有填充字段的注册表对象：

public class Registry {

    private List<Country> countries = new ArrayList<>();
}

public class Country {
    private String name; // <COUNTRY>...</COUNTRY>
    private List<Artist> artists = new ArrayList<>();
}

public class Artist {
    private String name; // <ARTIST>...</ARTIST>
    private List<Album> albums = new ArrayList<>();
}

public class Album {
    private String name; // <TITLE>...</TITLE>
    private int year; // <YEAR>...</YEAR>
}

和

public 类 Catalog {
```
@JacksonXmlProperty(localName = "CD")
```

@JacksonXmlElementWrapper(useWrapping = false)

私有列表 cds;
public list getCds（） {
归还CD;
```
}
```
}
公共类 Cd {
```
@JsonProperty("TITLE") // Album name
```
private String title;
```
@JsonProperty("ARTIST") // Artist name
```
私人弦乐艺术家;

@JsonProperty("COUNTRY") // Country name

私人弦乐国家;
```
@JsonProperty("COMPANY")
```
私人弦乐公司;
```
@JsonProperty("PRICE")
```
私人双倍价格;
```
@JsonProperty("YEAR")  // Album year
```
私人国际年;
}

Java XML Jackson XML 解析嵌套列表

using assembly System.Xml.Linq

$Filename = "c:\temp\test.xml"

$albums = [System.Collections.ArrayList]::new()  

$xDoc = [System.Xml.Linq.XDocument]::Load($Filename)
foreach($cd in $xDoc.Descendants("CD"))
{
   $newAlbum = New-Object -TypeName psobject
   
   $title = $cd.Element("TITLE").Value
   $newAlbum | Add-Member -NotePropertyName Title -NotePropertyValue $title

   $artist = $cd.Element("ARTIST").Value
   $newAlbum | Add-Member -NotePropertyName Artist -NotePropertyValue $artist   
   
   $country = $cd.Element("COUNTRY").Value
   $newAlbum | Add-Member -NotePropertyName Country -NotePropertyValue $country   
   
   $company = $cd.Element("COMPANY").Value
   $newAlbum | Add-Member -NotePropertyName Company -NotePropertyValue $company   
   
   $price = [decimal]$cd.Element("PRICE").Value
   $newAlbum | Add-Member -NotePropertyName Price -NotePropertyValue $price
     
   $year = [int]$cd.Element("YEAR").Value
   $newAlbum | Add-Member -NotePropertyName Year -NotePropertyValue $year


   $albums.Add($newAlbum) | Out-Null
}
Write-Host "All Albums"
$albums | Format-Table

上一个：Objectmapper.readerforupdating 不适用于嵌套对象

下一个：使用 ajax POST 方法将 String List<List<String>> 的嵌套列表传递给 Java SE 11
