postgresql – 具有logback的异步DBAppender

我正在开发一个使用logback进行日志记录的应用程序.我使用logback DBAppender将日志插入到DB中.

一切都很适合我,我能够插入日志并查看数据库.

我使用200个日志代码行进行了一些测试,并测量了这200个日志的时间消耗,并且在不使用DBAppender的情况下得到了10毫秒.当我添加DBAppender时,我得到了大约2700毫秒.

我试图使用ch.qos.logback.classic.AsyncAppender而没有运气使其异步工作.我总是将0结果插入到我的数据库中.

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>

我的配置有什么缺失吗？或者还有其他方法可以让它更快地将日志插入数据库吗？

请注意,我正在使用postgresql

谢谢,

编辑：

我在slf4j 1.7.5上使用logback 1.0.11.我也在使用postgresql 8.0.325.

logback报告了一条错误消息：

0:52:09,current pattern is [[configuration][appender][connectionSource][dataSource]]

这表明无法理解嵌套在其中的元素.以下是配置文件的相关部分：

<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没有.您可能希望使用以下命令配置DBAppPostgresql：

<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>
