Functions

func NewRabbitPublisher

func NewRabbitPublisher(file string, pool *database.Pool) *migration.MessageService

NewRabbitPublisher is a function that creates a new RabbitMQ publisher and publishes all messages from the database. It is used to publish messages that were not published due to a RabbitMQ connection failure. The messages are published in the same order they were created. The table used to store the messages is: create table if not exists RabbitCache(RabbitCacheID string primary key, DE_Exchange string, DE_RoutingKey string, JS_Data text, SN_Durable integer, TS_Operacao string) The table is created in memory and is not persisted. To send a message, you have to call the function Send of the message service that uses the same database connection. the function needs the following parameters: - exchange: the exchange name - routingKey: the routing key - data: the message data - durable: if the message is durable
