如何为 Log4J 使用两个不同的 XML-配置文件

Question

我有两个 XML-配置文件。一个用于我的 Java Jersey WebService，一个用于我的数据访问对象（=DAO；MySQL-DB via JDBC）。当我运行我的应用程序时，日志被分隔在两个不同的文件夹中，但日志文件彼此相同。

我怎样才能避免这种情况？

XML-DAO 的配置：

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

    <!-- CONSOLE -->    
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.out"/>
        <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>

    <!-- ERROR LOG INTO FILE -->
    <appender name="dberr" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/database/errlog.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" 
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="ERROR" />
            <param name="LevelMax" value="FATAL" />
        </filter>
    </appender>

    <!-- STANDARD LOG INTO FILE -->
    <appender name="dbstd" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/database/std.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" 
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="INFO" />
            <param name="LevelMax" value="WARN" />
        </filter>
    </appender>

    <!-- DEBUG LOG INTO FILE -->
    <appender name="dbdebug" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/database/debug.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"

        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="DEBUG" />
            <param name="LevelMax" value="DEBUG" />
        </filter>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="dberr" />
        <appender-ref ref="dbstd" />
        <appender-ref ref="dbdebug" />
    </root>

</log4j:configuration>

XML-Web 服务配置：

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

    <!-- CONSOLE -->    
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.out"/>
        <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>

    <!-- ERROR LOG INTO FILE -->
    <appender name="wserr" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/webservice/errlog.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" 
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="ERROR" />
            <param name="LevelMax" value="FATAL" />
        </filter>
    </appender>

    <!-- STANDARD LOG INTO FILE -->
    <appender name="wsstd" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/webservice/std.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" 
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="INFO" />
            <param name="LevelMax" value="WARN" />
        </filter>
    </appender>

    <!-- DEBUG LOG INTO FILE -->
    <appender name="wsdebug" class="org.apache.log4j.RollingFileAppender">
        <param name="append" value="true" />
        <param name="maxFileSize" value="5MB" />
        <param name="maxBackupIndex" value="5" />
        <param name="file" value="logs/webservice/debug.log" />
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" 
            value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="DEBUG" />
            <param name="LevelMax" value="DEBUG" />
        </filter>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="wserr" />
        <appender-ref ref="wsstd" />
        <appender-ref ref="wsdebug" />
    </root>

</log4j:configuration>

这就是我调用 Log4J 的方式：

Logger log  =   Logger.getLogger(DAO.class);
DOMConfigurator.configure("C:\file\path\to\config.xml");

我想要一个文件夹中包含来自 DAO 的日志 olny 的日志文件和 WebService 的等效文件。我哪里不好？

Answer 1

我将两个文件合并为一个 XML 文件。我需要做的是：

    <logger name="webservice_container">
        <appender-ref ref="wserr" />
        <appender-ref ref="wsstd" />
    </logger>

    <logger name="db_container">
        <appender-ref ref="dberr" />
        <appender-ref ref="dbstd" />
    </logger>

    <root>
        <level value="DEBUG" />
    </root>

现在我只有一个文件，因为我拥有 Log4J 的所有配置，它记录在 2 个不同的文件夹和 4 个不同的文件中。
