我发现了一个登录 clojure api 的问题。

我尝试为 API 请求和 SQL 语句实现日志记录机制。

项目.clj

    (defproject clojure-dauble-business-api "0.1.0-SNAPSHOT"
      :description "FIXME: write description"
      :url "http://example.com/FIXME"

                     [ring/ring-core "1.4.0"]
                     [ring/ring-jetty-adapter "1.4.0"]
                     [ring/ring-defaults "0.2.0"]

                     [org.slf4j/slf4j-simple "1.7.12"]
                     [org.clojure/tools.logging "0.3.1"]
                     [log4j/log4j "1.2.17" :exclusions [javax.mail/mail

                                                        com.sun.jmx/jmxri]]]
  :profiles {:dev {:resource-paths ["resources"]}}

  :plugins [[lein-ring "0.12.0"]]
  :main clojure-dauble-business-api.routes)

和

log4j.properties

# Application Logging
log4j.rootLogger=INFO, file

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=./log/app.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%d][%p][%c] %m%n

# # the appender used for the JDBC API layer call logging above, sql only
log4j.appender.sql=org.apache.log4j.RollingFileAppender
log4j.appender.sql.layout=org.apache.log4j.PatternLayout
log4j.appender.sql.layout.ConversionPattern= \u001b[0;31m (SQL)\u001b[m %d{yyyy-MM-dd HH:mm:ss.SSS} \u001b[0;32m %m \u001b[m %n

#
log4jdbc.drivers=org.postgresql.Driver
#
# # Log all JDBC calls except for ResultSet calls
log4j.logger.jdbc.audit=INFO,sql
log4j.additivity.jdbc.audit=false
#
# # Log only JDBC calls to ResultSet objects
log4j.logger.jdbc.resultset=INFO,sql

log4j.additivity.jdbc.sqltiming=false
#
# # Log connection open/close events and connection number dump
log4j.logger.jdbc.connection=INFO,sql
log4j.additivity.jdbc.connection=false

这里

[com.googlecode.log4jdbc/log4jdbc "1.2"]
[org.slf4j/slf4j-simple "1.7.12"]

覆盖日志记录机制。意味着，日志显示在控制台上，而不是创建 app.log 文件（根据 log4j.properties 配置）。

只有 API 请求日志显示在控制台上，并且不显示 SQL 日志。

为什么日志会显示在控制台上？以及如何在文件中记录 SQL 日志？

你的项目应该依赖slf4j-log4j12而不是slf4j-simple？自从

Binding for Simple implementation，将所有事件输出到 System.err。只打印级别 INFO 和更高级别的消息。此绑定在小型应用程序的上下文中可能很有用。

https://www.slf4j.org/manual.html

这应该是一个java问题。

编辑：

这实际上是第二个问题。

该log4jdbc库使用代理数据源来记录 sql 语句，因此您应该使用提供的数据源类log4jdbc net.sf.log4jdbc.Log4jdbcProxyDataSource

你可以通过搜索谷歌获得更多信息log4jdbc

我想出了我的问题的答案。

修改项目.clj
