我正在尝试使用NoUniqueBeanDefinitionException在Spring注解驱动的配置
类型没有合格的bean自动装配两个bean时,下面的错误[javax.jms.ConnectionFactory]定义: 预期单个匹配豆却发现2:aConnectionFactory,bConnectionFactory
Description:
Parameter 1 of method jmsListenerContainerFactory in org.springframework.boot.autoconfigure.jms.JmsAnnotationDrivenConfiguration required a single bean, but 2 were found:
- aConnectionFactory: defined by method 'aConnectionFactory' in package.Application
- bConnectionFactory: defined by method 'bConnectionFactory' in package.Application
Action:
Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
我已经此注解驱动的配置:
@SpringBootApplication
@EnableIntegration
@IntegrationComponentScan
public class Application extends SpringBootServletInitializer implements
WebApplicationInitializer {
@Resource(name = "aConnectionFactory")
private ConnectionFactory aConnectionFactory;
@Resource(name = "bConnectionFactory")
private ConnectionFactory bConnectionFactory;
@Bean
public IntegrationFlow jmsInboundFlow() {
return IntegrationFlows
.from(
Jms.inboundAdapter(aConnectionFactory)
.destination(aQueue),
e -> e.poller(Pollers.fixedRate(100,
TimeUnit.MILLISECONDS).maxMessagesPerPoll(100))
).channel("entrypoint")
.get();
}
@Bean
public IntegrationFlow jmsInboundFlowB() {
return IntegrationFlows
.from(
Jms.inboundAdapter(bConnectionFactory)
.destination(bQueue),
e -> e.poller(Pollers.fixedRate(100,
TimeUnit.MILLISECONDS).maxMessagesPerPoll(100))
).channel("entrypoint")
.get();
}
@Bean(name = "aConnectionFactory")
@Profile({"weblogic"})
public ConnectionFactory aConnectionFactory() {
ConnectionFactory factory = null;
JndiTemplate jndi = new JndiTemplate();
try {
factory = (ConnectionFactory) jndi.lookup("jms/ConnectionFactory");
} catch (NamingException e) {
logger.error("NamingException for jms/ConnectionFactory", e);
}
return factory;
}
@Bean(name = "bConnectionFactory")
@Profile({"weblogic"})
public ConnectionFactory bConnectionFactory() {
ConnectionFactory factory = null;
JndiTemplate jndi = new JndiTemplate();
try {
factory = (ConnectionFactory) jndi.lookup("jms/ConnectionFactory");
} catch (NamingException e) {
logger.error("NamingException for jms/ConnectionFactory", e);
}
return factory;
}
}
任何想法这段代码有什么问题?这似乎很简单,但指定限定符不起作用,我也尝试使用@Resource。我在那里错过了什么?
任何帮助表示赞赏。
春天混淆和@Bean(name =“aConnectionFactory”)。作为控制台建议你需要将它们标记为主(同bConnectionFactory) – kuhajeyan
