Spring @bean冲突解决方案

Posted 2022-06-21 21aspnet

引用2个jar都实现了相同的@bean注入，这个是feign的Level

@Bean
public Level feignLoggerLevel() 
        return Level.FULL;

这样报错:

escription:

xxx required a single bean, but 2 were found:
        - feignLoggerLevel: defined by method 'feignLoggerLevel' in class path resource [com/xxx.class]
        - logger: defined by method 'logger' in class path resource 
[com/yyy.class]


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

解决办法：

@Bean
    @ConditionalOnMissingBean(Logger.Level.class)
    public Level feignLoggerLevel() 
        return Level.FULL;
