示例1: save

let db: Db = await this.mongoDataSource.getConnection();
let insert = { name : todo.name, description : todo.description, completed : todo.completed };
let persistedTodo = await db.collection('todoCollection').insertOne(insert);

return await this.get(persistedTodoId);
}示例2: update
async update(todo:TodoModel):Promise<TodoModel> {
let db: Db = await this.mongoDataSource.getConnection();
let query = { "_id" : new ObjectID(todo.id) };
let update = { $set: { name : todo.name, description : todo.description, completed : todo.completed } };
