Question

我有一个春季启动应用程序，我正在努力使用滚动的appender策略进行日志记录。

这是我的pom.xml的相关部分

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.0.RELEASE</version>
  </parent>

  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
    </dependency>
    <dependency>
        <groupId>phoenix</groupId>
        <artifactId>phoenix</artifactId>
        <version>4.1.0-client-hadoop2</version>
    </dependency>
    <dependency>
      <groupId>commons-dbcp</groupId>
      <artifactId>commons-dbcp</artifactId>
      <version>20030825.184428</version>
    </dependency>
    <dependency>
      <groupId>org.apache.directory.studio</groupId>
      <artifactId>org.apache.commons.pool</artifactId>
      <version>1.6</version>
    </dependency>
  </dependencies>

当我只使用pom.xml运行我的应用程序时，我收到此错误：

java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError. See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

我读到了排除，所以我想我需要将排除添加到启动启动器，如下所示：

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
  <exclusions>
    <exclusion>
        <artifactId>log4j-over-slf4j</artifactId>
        <groupId>org.slf4j</groupId>
    </exclusion>
  </exclusions>
</dependency>

然后当我运行它时，我得到另一个错误：

java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/C:/maven/repo/phoenix/phoenix/4.1.0-client-hadoop2/phoenix-4.1.0-client-hadoop2.jar). If you are using Weblogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml Object of class [org.slf4j.impl.Log4jLoggerFactory] must be an instance of class ch.qos.logback.classic.LoggerContext

因此，我想与凤凰司机讨论一些冲突，但我不明白为什么。当我加载我的pom.xml并查看Dependency Heirarchy并查找该jar时，它不会列出我可以尝试排除的任何内容。

所以在这一点上我不知道如何继续。

要删除回退，请执行以下操作：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>log4j-over-slf4j</artifactId>
                    <groupId>org.slf4j</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>logback-classic</artifactId>
                    <groupId>ch.qos.logback</groupId>
                </exclusion>
            </exclusions>
        </dependency>

如此混淆如何使用Spring启动日志记录
