Question

我有所有必要的依赖项：

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.0.13</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.5</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jcl-over-slf4j</artifactId>
    <version>1.7.5</version>
</dependency>

但仍然在webapp启动时得到这个：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

它出现在Linux终端和Eclipse中。所以这不是m2e相关的。

以下是mvn dependency:tree的输出：

我正在使用tomcat7-maven-plugin运行我的webapp，它的目标是tomcat7:run。如果LogBACK在类路径中，我不知道在哪里查看，但是在运行目标package并查看创建的war文件的WEB-INF/lib时，我可以看到logback jar文件： enter image description here

Answer 1

您可以尝试获取有关依赖关系树的详细信息：

mvn dependency:tree -Dverbose

这将使用“重复问题”打印您的依赖关系树。我的怀疑是从tiles-jsp：3.0.1开始，详见上文：

1）使用apache webapp archetype创建了一个maven webapplication 2）将这些依赖项添加到pom.xml中：

    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.0.13</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.5</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.5</version>
    </dependency>
    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-jsp</artifactId>
        <version>3.0.1</version>
    </dependency>

3）使用mvn dependency:tree -Dverbose打印：

4）如果存在冲突，您应该使用<exclude>来消除冲突

尽管存在绑定依赖性，但无法加载StaticLoggerBinder
