如何配置 p6spy 将其输出重定向到文件中

Question

我能够成功配置 P6Spy 以拦截 JDBC 调用并将它们输出到 Eclipse 的控制台。但是，我希望在文件中捕获那些带有绑定参数的日志。有人可以帮助我了解如何做到这一点。这是我当前的配置：

log4j.properties

# Default log level
log4j.rootCategory=ERROR, console, FileAppender

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-5p %d [%t] %c: %m%n

# DEBUG File
log4j.appender.FileAppender=org.apache.log4j.RollingFileAppender
log4j.appender.FileAppender.Threshold=DEBUG
log4j.appender.FileAppender.File=claims_logger.log
log4j.appender.FileAppender.MaxFileSize=1024KB
log4j.appender.FileAppender.MaxBackupIndex=2
log4j.appender.FileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.FileAppender.layout.ConversionPattern=%-5p %d [%t] %c: %m%n

log4j.logger.org.apache=WARN

 log4j.logger.org.hibernate.engine.StatefulPersistenceContext.ProxyWarnLog=ERROR


log4j.logger.org.springframework.beans.factory=WARN

log4j.logger.org.mule=INFO
log4j.logger.org.mule.modules.sqs=DEBUG

log4j.logger.org.fuwt=DEBUG

spy.properties

realdriver=org.postgresql.Driver
useprefix=false
deregisterdrivers=true
module.log=com.p6spy.engine.logging.P6LogFactory

executionthreshold=

outagedetection=false
outagedetectioninterval=

filter=false

include     =

exclude     =

sqlexpression =

autoflush   = true

dateformat=yyyy-MM-dd hh:mm:ss

includecategories=

excludecategories=info,debug,result,batch

stringmatcher=

stacktrace=false

stacktraceclass=

reloadproperties=false


reloadpropertiesinterval=60


appender=com.p6spy.engine.logging.appender.StdoutLogger
append=true

log4j.additivity.p6spy=false

log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=p6spy - %m%n


log4j.logger.p6spy=DEBUG,STDOUT

Spring 正在使用以下方法构建其数据源：

jdbc.driverClassName=com.p6spy.engine.spy.P6SpyDriver

我使用的是 P6Spy 1.3 版。

我读到 log4jdbc 是对我的用例进行 SQL 拦截的首选方式，但它似乎需要稍微多一些配置，即需要修改 jdbc URL 根据 their doc。如果您有任何关于如何在任一框架中捕获参数并将其重定向到文件的经验，我们将不胜感激。

提前致谢。

Answer 1

您应该使用 FileAppender 并指定一个日志文件，如 https://p6spy.github.io/p6spy/2.0/configandusage.html

中所示


    # specifies the appender to use for logging
    # Please note: reload means forgetting all the previously set
    # settings (even those set during runtime - via JMX)
    # and starting with the clean table 
    # (only the properties read from the configuration file)
    # (default is com.p6spy.engine.spy.appender.FileLogger)
    #appender=com.p6spy.engine.spy.appender.Slf4JLogger
    #appender=com.p6spy.engine.spy.appender.StdoutLogger
    #appender=com.p6spy.engine.spy.appender.FileLogger

    # name of logfile to use, note Windows users should make sure to use forward slashes in their pathname (e:/test/spy.log) 
    # (used for com.p6spy.engine.spy.appender.FileLogger only)
    # (default is spy.log)
    #logfile = spy.log

事实证明，p6spy 中 appender 类的命名空间在其主要版本之间存在差异。我们碰巧使用的是 1.3 版的 p6spy，其中 FileLogger appender 位于：

appender=com.p6spy.engine.logging.appender.FileLogger

错误地，我们使用了以下配置，它属于 p6spy 的 2.x 版本：

appender=com.p6spy.engine.spy.appender.FileLogger

这会导致错误的行为。

让我们知道这一点的是对控制台日志的更彻底检查，其中发现了以下行：

Cannot instantiate com.p6spy.engine.spy.appender.FileLogger, even on second attempt.  Logging to file log4jaux.log: java.lang.ClassNotFoundException: com.p6spy.engine.spy.appender.FileLogger
