带有登录的异步DBAppender [英] Asynchronous DBAppender with logback

问题描述

我正在开发一个使用logback进行日志记录的应用程序.我使用了logback DBAppender将日志插入数据库.

I'm working on an application that uses logback for logging. I used the logback DBAppender to insert logs into DB.

对我来说，一切都很好，我能够将日志插入数据库中并查看日志.

All worked great for me and i was able to insert and see the logs into the Database.

我用200条记录的代码行进行了一些测试，并测量了这200条日志的时间消耗，并且在不使用DBAppender的情况下获得了10毫秒的时间.当我添加DBAppender时，我大约需要2700毫秒.

I did some testing with 200 logging line of code and measured the time consumption for those 200 logs and got 10 milliseconds without using the DBAppender. When i added the DBAppender i got around 2700 milliseconds.

我尝试在没有运气的情况下使用ch.qos.logback.classic.AsyncAppender使其异步工作.我总是将0个结果插入到我的数据库中.

I tried to use the ch.qos.logback.classic.AsyncAppender with no luck making it work asynchronously. I always get 0 results inserted into my database.

我的配置如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true"> 

 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <!-- encoders are  by default assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder -->
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>  

    <appender name="DBAppPostgreSQL" class="ch.qos.logback.classic.db.DBAppender">
        <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
            <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">
                  <driverClass>org.postgresql.Driver</driverClass>
                  <url>jdbc:postgresql://127.0.0.1:5678/DB</url>
                  <user>YYYYY</user>
                  <password>XXX</password>
            </dataSource>
        </connectionSource>
        <sqlDialect class="ch.qos.logback.core.db.dialect.PostgreSQLDialect" />
        <insertHeaders>true</insertHeaders>
</appender>

    <appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
            <appender-ref ref="DBAppPostgreSQL" />
            <includeCallerData>true</includeCallerData>
    </appender>

  <root level="debug">
      <appender-ref ref="ASYNC" />
      <appender-ref ref="STDOUT" />
  </root>
</configuration>

我的配置是否缺少任何内容?还是有其他方法可以使其更快地将日志插入数据库?

Is there anything missing with my configuration? Or is there any other way to make it insert logs into DB faster?

请注意，我正在使用postgreSQL

Note that i'm using postgreSQL

谢谢

已

我在slf4j 1.7.5上使用了logback 1.0.11.另外我正在使用PostgreSQL 8.0.325.

I'm using logback 1.0.11 over slf4j 1.7.5. Also i'm using postgresql 8.0.325.

推荐答案

logback报告了一条错误消息:

There is one error message reported by logback:

0:52:09,809 |-ERROR in ch.qos.logback.core.joran.spi.Interpreter@14:75 - no applicable action for [dataSource], current pattern is [[configuration][appender][connectionSource][dataSource]]

这表明无法理解嵌套在其中的元素.这是配置文件的相关部分:

This indicates that the element nested within could not be understood. Here is the relevant part of the configuration file:

<appender name="DBAppPostgreSQL" class="ch.qos.logback.classic.db.DBAppender">
  <!-- DriverManagerConnectionSource does not have a dataSource property -->
  <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
    <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">
      <driverClass>org.postgresql.Driver</driverClass>
      <url>jdbc:postgresql://127.0.0.1:5678/DB</url>
      <user>YYYYY</user>
      <password>XXX</password>
    </dataSource>
  </connectionSource>
  <sqlDialect class="ch.qos.logback.core.db.dialect.PostgreSQLDialect" />
  <insertHeaders>true</insertHeaders>
</appender>

ch.qos.logback.core.db.DriverManagerConnectionSource没有dataSource属性，而ch.qos.logback.core.db.DataSourceConnectionSource有.您可能要使用以下命令配置DBAppPostgreSQL:

ch.qos.logback.core.db.DriverManagerConnectionSource does not have a dataSource property whereas ch.qos.logback.core.db.DataSourceConnectionSource does. You probably want to configure DBAppPostgreSQL with:

<appender name="DBAppPostgreSQL" class="ch.qos.logback.classic.db.DBAppender">
  <!-- use DataSourceConnectionSource instead of DriverManagerConnectionSource -->
  <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource">
    <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">
      <driverClass>org.postgresql.Driver</driverClass>
      <url>jdbc:postgresql://127.0.0.1:5678/DB</url>
      <user>YYYYY</user>
      <password>XXX</password>
    </dataSource>
  </connectionSource>
  <sqlDialect class="ch.qos.logback.core.db.dialect.PostgreSQLDialect" />
  <insertHeaders>true</insertHeaders>
</appender>
