在带有嵌套 XML 模板的 Spring Boot 中使用 FreeMarker 模板

Question

所以我有以下 FreeMarker 模板：

<?xml version="1.0" encoding="ISO-8859-1"?>

<master>

    <header>

        <version>${version}</version>

        <created>${created}</created>

        <creator>${creator}</creator>

        <draw>${draw}</draw>

        <game>${game}</game>

        <type>${type}</type>

        <sender>${sender}</sender>

        <recipient>${recipient}</recipient>

        <revision>${revision}</revision>

    </header>

    <data>

        <stake>

        ${stake}

        </stake>

        <checksum_combifile>

        ${checksumFile}

        </checksum_combifile>

    </data>

</master>

一切都很好，一切都很甜蜜，但现在我想做以下事情，避免重复，因为我有许多具有相同标题结构的模板，将属于标题的变量移动到名为TemplateHeader的新类，如下所示：

public class TemplateHeader {

    /* Header */

    private String version;

    private String created;

    private String creator;

    private String draw;

    private String game;

    private String type;

    private String sender;

    private String recipient;

    private String revision;

    public TemplateHeader() {

        super();

    }

    public TemplateHeader(String version, String created, String creator, String draw, String game, String type, String sender, String recipient, String revision) {

        super();

        this.version = version;

        this.created = created;

        this.creator = creator;

        this.draw = draw;

        this.game = game;

        this.type = type;

        this.sender = sender;

        this.recipient = recipient;

        this.revision = revision;

    }

    public String getVersion() {

        return version;

    }

    public void setVersion(String version) {

        this.version = version;

    }

    public String getCreated() {

        return created;

    }

    public void setCreated(String created) {

        this.created = created;

    }

    public String getCreator() {

        return creator;

    }

    public void setCreator(String creator) {

        this.creator = creator;

    }

但是我不知道该怎么做，因为我从 FreeTemplate 收到错误，并且在网上找不到任何教程....
