rabbitmq配置类RabbitConfig中注入RabbitTemplate后在下面设置@BeanRabbitTemplate设置消息确认时springboot启动报错的问题

问题:在rabbitConfig配置类中既使用@Resource注入rabbitTemplate 又在下面使用@Bean声明一个RabbitTemplate用来设置消息确认时发现,springboot启动报错
报错信息如下:

大概错误是说创建rabbitTemplate的bean实例时出错,因为在这里使用的时注入进来的rabbitTemplate,而不是自己声明的那个.说明对象重复了
解决办法,去掉自动注入的rabbitTemplate,在@Bean中创建rabbitTemplate
在定义rabbitTemplate的bean时这样定义

@Bean
     public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
		RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
		...下面写自己配置
	 }
