如何在Odoo中调用自定义Python代码中的系统参数？

from odoo import api, fields, models

class MyModuleConfigSettings(models.TransientModel):
    _inherit = 'res.config.settings'

    my_system_param = fields.Char(string='My System Parameter', config_parameter='my_module.my_system_param')

    @api.model
    def get_values(self):
        res = super(MyModuleConfigSettings, self).get_values()
        res.update(
            my_system_param=self.env['ir.config_parameter'].sudo().get_param('my_module.my_system_param')
        )
        return res

    def set_values(self):
        super(MyModuleConfigSettings, self).set_values()
        self.env['ir.config_parameter'].sudo().set_param('my_module.my_system_param', self.my_system_param)

<odoo>
    <record id="view_my_module_config_settings_form" model="ir.ui.view">
        <field name="name">my.module.config.settings.form</field>
        <field name="model">res.config.settings</field>
        <field name="inherit_id" ref="base.view_res_config_settings_form"/>
        <field name="arch" type="xml">
            <xpath expr="//group[@name='base_config_settings']" position="inside">
                <group>
                    <field name="my_system_param"/>
                </group>
            </xpath>
        </field>
    </record>
</odoo>

<odoo>
    <data>
        <menuitem id="menu_my_module_config_settings" name="My Module Settings" parent="base.menu_config" sequence="10"/>
        <menuitem id="menu_my_module_config_settings_form" name="Configuration" parent="menu_my_module_config_settings" action="my_module.action_my_module_config_settings_form"/>
    </data>
</odoo>

from odoo import api, models

class MyClass(models.Model):
    _name = 'my.module.class'

    def my_method(self):
        my_system_param = self.env['ir.config_parameter'].sudo().get_param('my_module.my_system_param')
        # 在这里使用系统参数的值进行自定义逻辑处理
