报错
启动项目后报错,提示如下
2023-02-16 21:51:35.786 ERROR[main]o.s.boot.diagnostics.LoggingFailureAnalysisReporter.report:40 -
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 2 of method redisRateLimiter in org.springframework.cloud.gateway.config.GatewayRedisAutoConfiguration required a bean of type 'org.springframework.cloud.gateway.support.ConfigurationService' that could not be found.
Action:
Consider defining a bean of type 'org.springframework.cloud.gateway.support.ConfigurationService' in your configuration.
分析
查看org.springframework.cloud.gateway.config.GatewayRedisAutoConfiguration的源码如下,从第64行代码可以明显看出,实例化RedisRateLimiter(spring cloud gateway的redis限流器)这个类的时候,需要传三个参:redisTemplate、redisScript和configurationService。
根据报错提示可以明显看出,没有找到类型为org.springframework.cloud.gateway.support.ConfigurationService的Bean实例的Bean实例。

return redisScript;
}
@Bean
@ConditionalOnMissingBean
public RedisRateLimiter redisRateLimiter(ReactiveStringRedisTemplate redisTemplate,
@Qualifier(RedisRateLimiter.REDIS_SCRIPT_NAME) RedisScript<List<Long>> redisScript,
ConfigurationService configurationService) {
return new RedisRateLimiter(redisTemplate, redisScript, configurationService);
}
}
解决方法
既然缺少这个那我们就注入一个,新建配置类
import org.springframework.cloud.gateway.support.ConfigurationService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class RateLimiterConfig {
@Bean
ConfigurationService ConfigurationService(){
return new ConfigurationService();
}
}
再次启动后,项目正常运行。
