Question

在我的spring应用程序中，我正在尝试使用slf4j-log4j日志记录机制，但它似乎并不适用于我。它也没有给出任何错误，也没有初始化日志记录机制。

用pom.xml编写的

依赖关系如下......

     <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'

项目运行良好......但日志没有建立。这是我在tomcat上运行项目时控制台显示的内容

我唯一能看到的是你使用的是所有这些库的旧版本，并且可能提供的范围不适合你的配置。 Maven docs on provided：

<强>提供

这很像compile，但表示您希望JDK或容器在运行时提供依赖项。例如，在为Java Enterprise Edition构建Web应用程序时，您可以将Servlet API和相关Java EE API的依赖关系设置为提供的范围，因为Web容器提供了这些类。此范围仅在编译和测试类路径中可用，并且不可传递。

试试这个：

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.7</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.7</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.7</version>
</dependency>
<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>
<dependency>
   <groupId>log4j</groupId>
   <artifactId>log4j</artifactId>
   <version>1.2.14</version>
</dependency>

spring应用程序无法使用slf4j-log4j初始化日志记录
