JUL TO SLF4J on TomEE 1.7.2 with maven plugin
JUL TO SLF4J on TomEE 1.7.2 with maven plugin
我想在 tomee maven 项目中使用 SLF4J api 和 LOG4J2 impl。结果我在 pom.xml 中添加了 :
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jul-to-slf4j</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-slf4j-impl</artifactId>
<version>2.4</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-api</artifactId>
<version>2.4</version>
</dependency>
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.4</version>
</dependency>
我这样编辑了 TomEE 的 logging.properties 文件：
handlers = org.slf4j.bridge.SLF4JBridgeHandler
然后我尝试使用此 maven 命令 运行 我的项目：
mvn package tomee:run
不幸的是我遇到了一个例外：
objc[2756]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/bin/java and /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

我尝试将依赖项添加为 lib :
<plugin>
<groupId>org.apache.openejb.maven</groupId>
<artifactId>tomee-maven-plugin</artifactId>
<configuration>
<context>ROOT</context>
<libs>
<li>org.slf4j:slf4j-api:1.7.12</li>
<lib>org.slf4j:jul-to-slf4j:1.7.12</lib>
</libs>
</configuration>
</plugin>
我可以在 Maven 控制台中看到：
[INFO] Copied 'org.slf4j:slf4j-api:1.7.12' in '/Users/xxx/Work/Git/xxx/target/apache-tomee/lib/slf4j-api-1.7.12.jar

但我遇到了同样的异常:(
查看 jul-to-slf4j-1.7.12.jar 我可以看到 org.slf4j.bridge.SLF4JBridgeHandler class 文件存在。
我不明白为什么tomee找不到它？ mac 的 JDK 错误是否可能与此有关？ objc[10012]: Class JavaLaunchHelper is implemented in both ... libinstrument.dylib. One of the two will be used. Which one is undefined
谢谢！
