[GitHub] [incubator-dubbo-spring-boot-project] houhuacheng commented on issue #355: dubbo filter 配置不生效，最好整合日志slf4j，能有个像springcloud一样的traceId 日志追踪链

["houhuacheng (GitHub)" <gi...@apache.org>]

 springboot：2.0.5.RELEASE
 <dependency>
     <groupId>com.alibaba.boot</groupId>
     <artifactId>dubbo-spring-boot-starter</artifactId>
     <version>0.2.0</version>
 </dependency>
 
 
1.继承接口com.alibaba.dubbo.rpc.Filter实现public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException 方法
加上@Activate注解

    @Override
    public Result invoke(Invoker<?> invoker, Invocation invocation) throws RpcException {

        logger.info("111111111111111111111111");
        String tarceId = MDC.get(TraceConstant.TraceId);
        Map<String, String> attachments = invocation.getAttachments();
        attachments.put(TraceConstant.TraceId, tarceId);
        Result result=invoker.invoke(invocation);
        logger.info("222222222222222222222222");
        return result;

    }
2.配置文件修改
在resources目录下添加纯文本文件META-INF/dubbo/com.alibaba.dubbo.rpc.Filter
例如：traceIdFilter=com.xxx.TraceIdFilter
3.使用：
application.properties 配置 添加
dubbo.provider.filter =traceIdFilter   无效 不能注入filter  不能打印数字


@Reference(check = false,filter = traceIdFilter)依然无效
