測試用例未按預期運行？

Question

我在我的pom.xml中有下面的配置。

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

但是當我運行測試用例它給了我下面的錯誤：

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

    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) 

我失去了什麼嗎？

謝謝！

Answer 1

你可能需要包括以下內容的依賴，以及：如果你想使用SLF4J在Spring

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

Answer 2

那麼我建議你使用下面的依賴關係：

<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> 

我使用版本1.6.6的slf4j，但只要版本在每個依賴關係中保持一致，則無關緊要。
