model.config.id2label = {id: label for label, id in label2id.items()} model.config.label2id = label2id

好的，下面是Java邮箱配置的前后端代码实现。其中，前端使用了easyui框架，后端使用了SSM框架。 前端代码： HTML部分： ```html <div class="form-group"> <label class="col-sm-2 control-label">邮箱配置：</label> <div class="col-sm-10"> <div class="config-email-container"></div> <a href="#" class="btn btn-success btn-add-email" style="margin-top: 10px;">添加邮箱</a> ```

抱歉，由于基于Python的点餐系统的实现涉及到很多细节和功能模块，无法在一个回答中展示完整的代码。但是，我可以给您提供一些实现的思路和代码片段，希望对您有所帮助。 1. 使用Flask框架搭建后端服务器： ```python from flask import Flask, render_template, request from flask_sqlalchemy import SQLAlchemy app = Flask(__name__) app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://username:password@localhost/databasename' db = SQLAlchemy(app) class Menu(db.Model): id = db.Column(db.Integer, primary_key=True) name = db.Column(db.String(100)) price = db.Column(db.Float) category = db.Column(db.String(50)) class Order(db.Model): id = db.Column(db.Integer, primary_key=True) customer_name = db.Column(db.String(100)) customer_phone = db.Column(db.String(20)) order_items = db.relationship('OrderItem', backref='order') class OrderItem(db.Model): id = db.Column(db.Integer, primary_key=True) order_id = db.Column(db.Integer, db.ForeignKey('order.id')) menu_id = db.Column(db.Integer, db.ForeignKey('menu.id')) quantity = db.Column(db.Integer) @app.route('/') def index(): menus = Menu.query.all() return render_template('index.html', menus=menus) @app.route('/order', methods=['POST']) def order(): customer_name = request.form['customer_name'] customer_phone = request.form['customer_phone'] order_items = [] for menu_id, quantity in request.form.items(): if menu_id.isdigit() and int(quantity) > 0: menu = Menu.query.get(menu_id) order_items.append(OrderItem(menu=menu, quantity=quantity)) order = Order(customer_name=customer_name, customer_phone=customer_phone, order_items=order_items) db.session.add(order) db.session.commit() return 'Order placed successfully!' ```
