API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field)
can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6).

            addFieldToSource(sourceMap, "username", username);
        }
        return sourceMap;
    }

    protected void addFieldToSource(Map<String, Object> sourceMap, String field, Object value) {
        sourceMap.put(field, value);
    }

    // ===================================================================================
    //                                                                      Basic Override

        return sourceMap;

有一些区别：

* `table=True` 会告诉 SQLModel 这是一个*表模型*，它应该表示 SQL 数据库中的一个*表*，而不仅仅是一个*数据模型*（就像其他常规的 Pydantic 类一样）。

* `Field(primary_key=True)` 会告诉 SQLModel `id` 是 SQL 数据库中的**主键**（您可以在 SQLModel 文档中了解更多关于 SQL 主键的信息）。

    把类型设置为 `int | None` ，SQLModel 就能知道该列在 SQL 数据库中应该是 `INTEGER` 类型，并且应该是 `NULLABLE` 。

* `Field(index=True)` 会告诉 SQLModel 应该为此列创建一个 **SQL 索引**，这样在读取按此列过滤的数据时，程序能在数据库中进行更快的查找。

 * to be lightweight yet powerful, supporting various scopes of object lifecycle from
 * singleton instances to mojo-execution-scoped beans.
 * <p>
 * Key features include:
 * <ul>
 *   <li>Constructor, method, and field injection</li>
 *   <li>Qualifiers for distinguishing between beans of the same type</li>
 *   <li>Multiple scopes (Singleton, Session, and MojoExecution)</li>
 *   <li>Priority-based implementation selection</li>
