    // 使用模型文件里面relations方法获取预定义的关联模型配置
    BookModel::with(['author','comments'])->select();
    BookModel::instance()->with(['author','comments'])->select();

    // 直接传入关联模型配置，将与预定义关联模型合并
    BookModel::with(['author'=>[
        'relation_model' => AuthorModel::class,
        'relation_table' => 'authors',
        'relation_key'   => 'id',
        'foreign_key'    => 'author_id',
        'mapping_name'   => 'author',
        'mapping_type'   => RelationModel::BELONGS_TO,
        'condition'      => [],
    ]])->select();

    // 设置关联查询回调
    BookModel::with(['author'=>function($query){
        $query->where(['name'=>'张三']);
    }])->select();

    // 子关联模型
    BookModel::with(['author.books','comments'=>['with'=>'user']])->select();
    BookModel::with(['author.books','comments'=>['with'=>['user']]])->select();
