java - JasperReports JAR 文件导致使用 Log4j 进行过多日志记录

标签 java tomcat logging jar log4j

我正在使用 Tomcat 和 Log4j 开发 Java Web 应用程序。我正在将 DynamicReports 4.1.1 与应用程序集成。 DynamicReports 依赖于名为 jasperreports6.2.2-jar 的 JAR 文件。在我将上述 JAR 文件添加到项目后，Log4j 开始每天每分钟记录一次无用的垃圾，并且在用户请求应用程序的网页时也是如此。这在生产环境中是 Not Acceptable ，并且会使应用程序的调试变得困难。

我需要维护应用程序的日志记录，但我不希望 JasperReports 全天候或在用户请求网页时强制进行不必要的日志记录。

是什么导致 JasperReports 执行这种过多的日志记录？

如何阻止 JasperReports 触发日志记录机制，但仍然在整个应用程序的其余部分保持定期日志记录？

如果我不能轻易做到这一点(吃蛋糕也吃)，为什么不呢？

请注意，我愿意深入挖掘有问题的 JAR 文件中的 JasperReports 源代码，并在必要时重新编译它以完成这项工作。

这是我的 log4j.properties 文件。在我采用它之前，以及在我添加 DynamicReports 之前，它就一直在我的项目的类路径目录中。

# Root loggin directory
logDir=/usr/local/tomcat/logs

# Root logger option
log4j.rootLogger=INFO, file

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=${logDir}/detailed_debug.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

这是一天中每一分钟都涌入我的日志文件的垃圾。请注意，打印这些消息的代码出现在我的应用程序中的一个 java 类中，该类处理在一天中的特定时间发送电子邮件。

此外，这里还有一个垃圾示例，当用户访问我的应用程序中的网页时，垃圾会喷到我的日志文件中。我相信在我将任何 DynamicReports 库添加到项目之前很久，日志文件的这一部分中引用的对象就已经是我的应用程序的一部分。

最佳答案

问题是，无论出于何种原因，当项目中包含 JasperReports jar 文件时，log4j 会忽略 log4j.properties 文件。在 WEB-INF 目录中创建一个 log4j.xml 文件并在 DEBUG 之上为其提供一些配置选项解决了该问题。

这是我用来解决问题的 log4j.xml 文件的内容:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true" xmlns:log4j='http://jakarta.apache.org/log4j/'>

<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern"
      value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
    </layout>
</appender>

<root>
    <level value="INFO" />
    <appender-ref ref="console" />
</root>
