spring-boot - 使用 spring-JMS 和 spring cloud sleuth 时的 BeanNotOfRequiredTypeException

Question

我有带有 Spring Cloud sleuth 的 spring boot 项目(2.1.0 版本)。Spring Sleuth 的 TracingConnectionFactoryBeanPostProcessor 正在使用 LazyConnectionFactory Bean 覆盖 ConnectionFactory bean。因此，我正在点击:

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'userCredentialsConnectionFactoryAdapter' is expected to be of type 'org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter' but was actually of type 'org.springframework.cloud.sleuth.instrument.messaging.LazyConnectionFactory'

任何人都可以为此提出解决方案/解决方法。

Answer 1

>@Bean
>public JmsTemplate jmsTemplate(UserCredentialsConnectionFactoryAdapter conFactory){

不要注入(inject)具体类型；而是注入(inject)接口(interface)

@Bean
public JmsTemplate jmsTemplate(ConnectionFactory conFactory){

并在必要时使用 @Qualifier 对其进行限定，或者使用正确的 bean 名称作为参数名称。
