java.lang.NoClassDefFoundError：org / apache / log4j / Priority
作者：互联网
我正在跟踪一个自定义日志记录工具,以使用log4j实现电子邮件的日志记录功能.
我已将log4j：1.2.17的依赖项以及jar添加到类路径.我正在尝试使用Arquillian进行测试.但是每次我遇到同样的错误.
我知道它即将出现,就像我使用的是Level而不是现在不推荐使用的Priority一样.我也添加了正确的jar和导入,但是运行Test时仍然会出现错误.
我也提到了这些链接,但对我来说没有用.
What’s causing this Maven/JBehave error?

有人知道如何解决此错误吗？
这是我的EmailTest.java类的摘录：
import org.jboss.arquillian.container.test.api.Deployment;
import org.jboss.arquillian.junit.Arquillian;
import org.jboss.shrinkwrap.api.ShrinkWrap;
import org.jboss.shrinkwrap.api.asset.EmptyAsset;
import org.jboss.shrinkwrap.api.spec.JavaArchive;
import org.junit.*;
import org.junit.runner.RunWith;
import org.apache.log4j.Level;
import org.apache.log4j.spi.LoggingEvent;
import org.apache.log4j.spi.RootLogger;
import javax.inject.Inject;
public class EmailTest{
@Inject
private Email email;
@Deployment //(testable = true)
public static JavaArchive createTestArchive(){
return ShrinkWrap.create(JavaArchive.class, "test.jar")
.addClasses(ErrorEmailThrottle.class)
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");}
@Test
public void noFatalError(){
Assert.assertEquals(email.isTriggeringEvent(createLogEvent(Level.FATAL, System.currentTimeMillis())), true);
Assert.assertEquals(email.isInThrottleMode(), false);
}
.....
private LoggingEvent createLogEvent(Level level, long time) {
return new LoggingEvent("Email", new RootLogger(Level.INFO) , time, level, "Email message", null);
}
}
这是我的pom.xml依赖项：
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
<!--<scope>test</scope>-->
<exclusions>

解决方法:
我刚刚检查了Log4j 1.2.17源代码,并且org.apache.log4j.Priority仍然存在.
因此,问题可能出在您的依赖项未正确添加上.
可能有几种可能性：
>您已将< dependency> < dependencyManagement>下的阻止而不是< dependencies>
>还声明了Maven决定采用的其他依赖项.它应该可以在项目中通过mvndependency：tree轻松验证.您可以看到采用了哪个版本的log4j
>您的文件已损坏或为空或任何其他内容.检查本地存储库中log4j：log4j：1.2.17的内容.
