从FreeMarker中的模板字符串获取所有依赖项名称(甚至多级继承)的列表

String templateString = "<your template string>"; // 替换为实际的模板字符串
Template template = new Template("template", new StringReader(templateString), new Configuration());

List<String> dependencies = new ArrayList<>();
Map<String, Macro> macros = template.getMacros();
for (Macro macro : macros.values()) {
    dependencies.add(macro.getName());
}

List<String> getAllDependencies(Template template) {
    List<String> dependencies = new ArrayList<>();
    Map<String, Macro> macros = template.getMacros();
    for (Macro macro : macros.values()) {
        dependencies.add(macro.getName());
    }
    
    List<String> parentDependencies = new ArrayList<>();
    String parentTemplateName = template.getParentName();
    if (parentTemplateName != null) {
        Template parentTemplate = template.getConfiguration().getTemplate(parentTemplateName);
        parentDependencies = getAllDependencies(parentTemplate);
    }
    
    dependencies.addAll(parentDependencies);
    return dependencies;
}

List<String> allDependencies = getAllDependencies(template);
