我正在使用apache kafka、Spring cloud sleuth和sleuth otel依赖项，我得到了错误

Question

类路径资源[org/springframework/cloud/sleuth/instrument/web/client/TraceWebClientAutoConfiguration$restemplateconfig$TraceInterceptorConfiguration.class]中定义的bean“traceresttemplatebeanpostsprocessor”，[org/springframework/cloud/sleuth/autoconfig/instrument/web/client/TraceWebClientAutoConfiguration$restemplateconfig$TraceInterceptorConfiguration.class]并禁用覆盖

POM文件中使用的附加sleuth依赖项：

Answer 1

默认情况下，Spring Boot 2.1中禁用了bean的重写。您可以尝试添加Spring。主要的在yml中允许bean定义重写=true，或者使用@ComponentScan从SpringBootApplication类中排除父配置。

Example : 

@SpringBootApplication
@ComponentScan(excludeFilters = 
        {@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = TraceInterceptorConfiguration.class)})
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}
