Java Play-使用映射绑定对象列表<；字符串，另一个对象>；在…内

我正在使用Java Play framework 2.6。我试图给出一个对象列表（在本例中为章节）。每个章节对象包含在一个地图字段中。要以简单的方式说明这一点：

public class ListChapters {
    private List<Chapter> formChapters;

    public List<Chapter> getFormChapters() {
        return formChapters;
    }

    public ListChapters setFormChapters(List<Chapter> formChapters) {
        this.formChapters = formChapters;
        return this;
    }
}  

public class Chapter {
    private String name;

    private Map<String, Material> materials;

    public String getName() {
        return name;
    }

    public Chapter setName(String name) {
        this.name = name;
        return this;
    }

    public Map<String, Material> getMaterials() {
        return materials;
    }

    public Chapter setMaterials(Map<String, Material> materials) {
        this.materials = materials;
        return this;
    }
}

public class Material {
    private String code;

    public String getCode() {
        return code;
    }

    public Material setCode(String code) {
        this.code = code;
        return this;
    }
}

这不是形成输入名称的正确方法吗，这样绑定就完成了？或者可能是什么问题

非常感谢您的帮助。

Play framework表单请求绑定始终假定集合键（列表、映射）将在方括号中提供
