How to log MDC with Spring Sleuth 2.0?

由 亡梦爱人 提交于 2020-01-13 20:35:35
问题 referring to quesition/answer in How to log MDC with Spring Sleuth? I think this has/will change(d) with spring-cloud 2.0 as there is no SpanLogger or Slf4jSpanLogger anymore (or I don't find it) Wouldn't it be nice if application properties spring.sleuth.baggage-keys and spring.sleuth.propagation-keys if set would also be put in MDC I think inside Slf4jCurrentTraceContext (as this class is currently final I cannot subclass it) If not, how could I achieve this with spring-cloud 2.0

How to use log4j 2.0 and slf4j and Commons Logging together

由 江枫思渺然 提交于 2020-01-12 03:11:46
问题 I currently am starting a new Webapp (running on tomcat 6) I have components using slf4j and components using commons logging I plan to use log4j 2.0 as log implementation due to several reasons (mainly for the appenders:SocketAppender and SyslogAppender but also because of the promoted config reloading without loss of log events) Now my questions are: - To which interface do I program my new classes? loag4j or slf4j? or even commons logging? What's the preferred way to deploy the jars? put

What's the overhead of creating a SLF4J loggers in static vs. non-static contexts?

由 China☆狼群 提交于 2020-01-10 08:45:20
问题 I've always used the following pattern to construct (SLF4J) loggers: private static final Logger log = LoggerFactory.getLogger(MyClass.class); This has worked so far, but I was wondering about the static context at some point and the need to pass in the concrete class literal all the time instead of just using a non-static logger like private final Logger log = LoggerFactory.getLogger(getClass()); This has basically been asked (and answered) before here for LOG4J Should logger be private

SpringBoot基于Aop自定义Slf4j日志输出格式

由 余生颓废 提交于 2020-01-09 20:11:04
需求 当线上服务或者接口出现异常之后，第一时间需要做的就是追踪日志，找出问题到底出现在哪里，但是在现有的分布式及微服务的背景下，一个请求的调用链往往比较的长，所以一般情况下会选择使用一个请求的唯一ID输出为日志，然后便于日常运维过程的问题追踪，如何优雅自如的自定义一个log输出呢？下面使用AOP加上logback来给一个简单优雅的方式；解放双手，告别体力活。 Aop 这里不做AOP的介绍。除了使用AOP也可以使用Filter去做，不管是AOP还是Filter，目的就是在请求来的时候将其拦住，然后往MDC中塞入自定义的一一些属性，即可实现自定义的变量输出 何为MDC？ 这里的MDC就是一个工具类，其本质就是使用 ThreadLocal 将自定义的变量存储起来，这么一说相信各位就知道这个自定义参数的套路了；请求之前将请求拦截，将自定义的属性值存进去；业务过程中，如果打印日志，就将本地ThreadLocal中自定义的属性一起输出。其实原理就这么简单，具体要如何输出，要输出什么，就得看你自己的骚操作了！！！ 配置 logback-spring.xml <?xml version="1.0" encoding="UTF-8"?> <configuration debug="true" scan="true" scanPeriod="30 seconds"> <!--

Hibernate 3.4 with slf4j and log4j

由 可紊 提交于 2020-01-09 07:14:49
问题 I'm attempting to upgrade from Hibernate 3.2 to 3.4, which apparently uses slf4j. Our project currently uses log4j. So my assumption is that I should be using the slf4j-log4j12 wrapped implementation. The Maven slf4j dependency is: <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.5.6</version> </dependency> While the log4j dependency is: <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.15</version> </dependency> Both
