Clojure REST API：记录问题

Question

我发现了登录 clojure 的一个问题 api。

我尝试为 API 请求和 SQL 语句实现日志记录机制。

Project.clj

    (defproject clojure-dauble-business-api "0.1.0-SNAPSHOT"
      :description "FIXME: write description"
      :url "http://example.com/FIXME"
      :license {:name "Eclipse Public License"
                :url "http://www.eclipse.org/legal/epl-v10.html"}
      :ring {:handler clojure-dauble-business-api.routes/app}
      :dependencies [[org.clojure/clojure "1.8.0"]
                     [metosin/compojure-api "1.1.10"]
                     [ring/ring-core "1.4.0"]
                     [ring/ring-jetty-adapter "1.4.0"]
                     [ring/ring-defaults "0.2.0"]
                     [org.clojure/java.jdbc "0.6.1"]
                     [yesql/yesql "0.5.3"]
                     [org.postgresql/postgresql "9.4.1212"]
                     [org.clojure/data.json "0.2.6"]
                     [cheshire "5.7.1"]
                     [com.googlecode.log4jdbc/log4jdbc "1.2"]
                     [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

# # the appender used for the JDBC API layer call logging above, sql only

#
log4jdbc.drivers=org.postgresql.Driver
#

此处

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

覆盖日志记录机制。意思是，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，它不显示 SQL 日志。

为什么控制台上会显示日志？以及如何在文件中记录 SQL 日志？

Answer 1

您的项目应该依赖于 slf4j-log4j12 而不是 slf4j-simple？自

Binding for Simple implementation, which outputs all events to System.err. Only messages of level INFO and higher are printed. This binding may be useful in the context of small applications.

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

应该是一道java题。

编辑：

实际上这是第二个问题。

log4jdbc 库使用代理数据源来记录 sql 语句，因此您应该使用 log4jdbc net.sf.log4jdbc.Log4jdbcProxyDataSource [=] 提供的数据源 class

您只需通过 log4jdbc

搜索 google 即可获得更多信息
