android - 如何将arraylist存储在ormlite数据库中

Question

我试图将类对象的数组列表保存到 ormlite 数据库中，但它给出了错误，java.lang.IllegalArgumentException:类 java.util.ArrayList 中没有字段具有 DatabaseField 注释

我的代码是

@DatabaseTable
public class ManageModelDetails {

@DatabaseField(generatedId = true)
private int id;

@DatabaseField(foreign = true, foreignAutoRefresh = true)
private ArrayList<ModelDetails> listModelDetails;

// ===============================================
public ManageModelDetails() {
    super();
}

// ===============================================

public ManageModelDetails(int id, ArrayList<ModelDetails> listModelDetails) {
    super();
    this.id = id;
    this.listModelDetails = listModelDetails;
}

// ===============================================

public void setId(int id) {
    this.id = id;
}

public int getId() {
    return id;
}

public void setModelList(ArrayList<ModelDetails> listModelDetails) {
    this.listModelDetails = listModelDetails;
}

public ArrayList<ModelDetails> getModelList() {
    return listModelDetails;
}

}
