春季應用程序無法使用slf4j-log4j初始化日誌記錄

Question

在我的spring應用程序中，我試圖使用slf4j-log4j日誌記錄機制，但它似乎不適用於我。它也沒有給出任何錯誤，也沒有初始化記錄機制。寫在pom.xml中

依賴關係如下...

 <dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-context</artifactId> 
     <version>${springVersion}</version> 
     <exclusions> 
     <exclusion> 
      <groupId>commons-logging</groupId> 
      <artifactId>commons-logging</artifactId> 
     </exclusion> 
     </exclusions> 
    </dependency> 

    <!-- log4j and slf4j --> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>jcl-over-slf4j</artifactId> 
     <version>1.6.1</version> 
    </dependency> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-api</artifactId> 
     <version>1.6.1</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>org.slf4j</groupId> 
     <artifactId>slf4j-log4j12</artifactId> 
     <version>1.6.1</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>log4j</groupId> 
     <artifactId>log4j</artifactId> 
     <version>1.2.14</version> 
     <scope>provided</scope> 
    </dependency> 

log4j.properties文件是如下

log4j.rootLogger=INFO, file, stdout 
log4j.appender.stdout=org.apache.log4j.ConsoleAppender 
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 
log4j.appender.stdout.layout.ConversionPattern=[%5p] %d{mm:ss} (%F:%M:%L)%n%m%n%n 

log4j.appender.file=org.apache.log4j.DailyRollingFileAppender 
log4j.appender.file.File=D:/logs/ov/ov 
log4j.appender.file.layout=org.apache.log4j.PatternLayout 
log4j.appender.file.layout.ConversionPattern=%d %m %n 
log4j.appender.file.DatePattern=yyyy-MM-dd-HH'.log' 

項目運行良好...但日誌沒有得到建成。這是控制檯顯示，當我在Tomcat

運行項目，我可以看到的唯一的事情是，你用的是很老的版本，所有這些庫的，而且可能提供的範圍不適合您的配置。 Maven docs on provided：

提供

這很像編譯，而是指你所期望的JDK或容器，以提供在運行時的依賴。例如，在爲Java Enterprise Edition構建Web應用程序時，您可以將Servlet API和相關Java EE API的依賴性設置爲範圍，因爲Web容器提供了這些類。此範圍僅在編譯和測試類路徑中可用，且不是傳遞性的。

試試這個：
