二、Declarable接口的源码如下：

package org.springframework.amqp.core;

import java.util.Collection;

public interface Declarable {
	boolean shouldDeclare();

	Collection<?> getDeclaringAdmins();

	boolean isIgnoreDeclarationExceptions();
}

三、Declarable接口的分析如下：

Declarable接口中共计3个抽象接口
1 . 接口1：是否应自动声明此对象。如果应声明对象，则为true。

boolean shouldDeclare();

2 . 接口2：对象如果为空，则所有管理员都应声明集合。

Collection<?> getDeclaringAdmins();

3 . 接口3：声明时是否应忽略异常（例如不匹配的参数）。如果要忽略，则为true。

boolean isIgnoreDeclarationExceptions();
