Spring 注解驱动配置中的 NoUniqueBeanDefinitionException [英] NoUniqueBeanDefinitionException in Spring annotation driven configuration
问题描述
尝试使用
没有定义类型为 [javax.jms.ConnectionFactory] 的合格 bean:预期单个匹配 bean,但发现 2:aConnectionFactory, bConnectionFactory
No qualifying bean of type [javax.jms.ConnectionFactory] is defined: expected single matching bean but found 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
我有这个注释驱动的配置:
I have this annotation driven configuration:
@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;
}
}
知道这段代码有什么问题吗?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?
Any ideas what's wrong in this code? This seems to be straight forward, but specifying the Qualifier doesn't work, I have also tried to use @Resource. What am I missing there?
任何帮助表示赞赏.
推荐答案
您的代码没有问题.
那只是来自 Spring Boot 的 JmsAnnotationDrivenConfiguration
,它不喜欢你的两个 ConnectionFactory
bean,但只需要一个.
That is just JmsAnnotationDrivenConfiguration
from Spring Boot which doesn't like your two ConnectionFactory
beans, but requires only one.
为什么不遵循该报告建议并用
@Primary
标记其中之一?
看起来您没有使用 Spring Boot JMS 自动配置功能,因此禁用 JmsAnnotationDrivenConfiguration
很简单:http://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/reference/htmlsingle/#using-boot-disabling-specific-auto-configuration
Looks like you don't use Spring Boot JMS auto-configuration feature, so that would be just straightforward to disable JmsAnnotationDrivenConfiguration
