Question

我是maven和storm的新手。我尝试通过此命令以本地模式运行myTopology

mvn compile exec:java -Dstorm.topology=my.Topology

但是我收到了这个错误

clojure.tools.logging$eval1$fn__7 invoke
SEVERE: Async loop died!
java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V

我使用了mvn dependency:tree并获得了

[INFO]    +- org.slf4j:slf4j-api:jar:1.7.5:provided
[INFO]    +- org.slf4j:log4j-over-slf4j:jar:1.6.6:provided

我试图在pom中添加这些行

 <exclusions>
      <exclusion>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
      </exclusion>
    </exclusions>

但在执行mvn dependency:tree

后得到了

+- org.slf4j:log4j-over-slf4j:jar:1.6.6:provided

同样的错误仍然是

Answer 1

以下适用于我：

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.22</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-slf4j-impl</artifactId>
        <version>2.7</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.7</version>
    </dependency>
</dependencies>

测试是：

package com.greg;

import static org.junit.Assert.*;

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class AppTest {

    @Test
    public void test1() {
        Logger logger = LoggerFactory.getLogger(AppTest.class);
        logger.debug("hello greg");
        assertTrue(true);
    }
}

确保资源目录中有log4j.xml。
