Question

我的pom.xml中有以下配置。

<dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.5.2</version>
        </dependency>

但是当我运行测试用例时，它会给我以下错误：

java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

我在这里错过了什么吗？

谢谢！

Answer 1

您可能还需要包含以下依赖项：

<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-api</artifactId>
   <version>1.5.2</version>
</dependency>

如果你想在Spring上使用slf4j，我建议你使用以下依赖项：

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>${slf4j-version}</version>
</dependency>

<!--
    This forces the Java commons logging that is used as part of Spring
    to use slf4j
-->
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>jcl-over-slf4j</artifactId>
  <version>${slf4j-version}</version>
  <scope>runtime</scope>
</dependency>

<!--
    Use log4j as the slf4j implementation
-->
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>${slf4j-version}</version>
  <scope>runtime</scope>
</dependency>

<!--
    You will also need log4j itself.
    It includes a lot of cruft, so exclude the parts you don't want.
-->
<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.15</version>
  <exclusions>
    <exclusion>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
    </exclusion>
    <exclusion>
      <groupId>javax.jms</groupId>
      <artifactId>jms</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jdmk</groupId>
      <artifactId>jmxtools</artifactId>
    </exclusion>
    <exclusion>
      <groupId>com.sun.jmx</groupId>
      <artifactId>jmxri</artifactId>
    </exclusion>
  </exclusions>
  <scope>runtime</scope>
</dependency>

我正在使用slf4j的1.6.6版本，但只要版本在每个依赖项中保持一致，它就没那么重要了。

测试用例未按预期运行？
