InstanceId	interface{}	Property instanceId: InstanceId.
Internal	interface{}	Property internal: Specifies whether an exchange is an internal exchange.
VirtualHost	interface{}	Property virtualHost: The name of the virtual host.
AlternateExchange	interface{}	Property alternateExchange: The alternate exchange.
XDelayedType	interface{}	Property xDelayedType: Exchanges of the x-delay-Message type allow you to customize the Header property of the message, and the x-delay specifies the amount of time in milliseconds for the message to be delivered.

AutoDeleteState^Required

AutoDeleteState interface{}

• Type: interface{}

Property autoDeleteState: Specifies whether the Auto Delete attribute is configured.

Valid values: true: The Auto Delete attribute is configured. If the last queue that is bound to an exchange is unbound, the exchange is automatically deleted. false: The Auto Delete attribute is not configured. If the last queue that is bound to an exchange is unbound, the exchange is not automatically deleted.

---

ExchangeName^Required

ExchangeName interface{}

• Type: interface{}

Property exchangeName: The name of the exchange.

---

ExchangeType^Required

ExchangeType interface{}

• Type: interface{}

Property exchangeType: The type of the exchange.

Valid values: FANOUT: An exchange of this type routes all the received messages to all the queues bound to this exchange. You can use a fanout exchange to broadcast messages. DIRECT: An exchange of this type routes a message to the queue whose binding key is exactly the same as the routing key of the message. TOPIC: This type is similar to the direct exchange type. An exchange of this type routes a message to one or more queues based on the fuzzy match or multi-condition match result between the routing key of the message and the binding keys of the current exchange. HEADERS: Headers Exchange uses the Headers property instead of Routing Key for routing matching. When binding Headers Exchange and Queue, set the key-value pair of the binding property; when sending a message to the Headers Exchange, set the message's Headers property key-value pair and use the message Headers The message is routed to the bound Queue by comparing the attribute key-value pair and the bound attribute key-value pair.

---

InstanceId^Required

InstanceId interface{}

• Type: interface{}

Property instanceId: InstanceId.

---

Internal^Required

Internal interface{}

• Type: interface{}

Property internal: Specifies whether an exchange is an internal exchange.

Valid values: false: The exchange is not an internal exchange. true: The exchange is an internal exchange.

---

VirtualHost^Required

VirtualHost interface{}

• Type: interface{}

Property virtualHost: The name of the virtual host.

---

AlternateExchange^Optional

AlternateExchange interface{}

• Type: interface{}

Property alternateExchange: The alternate exchange.

An alternate exchange is configured for an existing exchange. It is used to receive messages that fail to be routed to queues from the existing exchange.

---

XDelayedType^Optional

XDelayedType interface{}

• Type: interface{}

Property xDelayedType: Exchanges of the x-delay-Message type allow you to customize the Header property of the message, and the x-delay specifies the amount of time in milliseconds for the message to be delivered.

The routing rules for this class of exchanges depend on the Exchange type specified in the x-delay-type parameter, which specifies the actual Exchange type to which the delayed message will eventually be delivered. Valid values:

• DIRECT: Delivers deferred messages to a specified queue bound to an Exchange of type DIRECT.

• TOPIC: Delivers deferred messages to the queue bound to the Exchange type TOPIC.

• FANOUT: Delivers deferred messages to a queue bound to an Exchange of type FANOUT.

• HEADERS: Deferred messages are delivered to the queue bound to the Exchange HEADERS type.

• X-JMS-TOPIC: Delivers deferred messages to the queue bound to X-JMS-TOPIC.
