我开始使用 Corda5，当我执行命令“./gradlew runPartyAServer”时，抛出 SLF4J: Class path contains multiple SLF4J bindings

Question

SLF4J：类路径包含多个 SLF4J 绑定。 SLF4J：在 [jar:file:/home/cc-dev/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.17.1/84692d456bcce689355d33d68167875e486954dd/ 中找到绑定log4j-slf4j-impl-2.17.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J：在 [jar:file:/home/cc-dev/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.2.3/7c4f3c474fb2c041d8028740440937705ebb473a/logback-classic- 中找到绑定1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J：有关解释，请参阅http://www.slf4j.org/codes.html#multiple_bindings。 SLF4J：实际绑定类型为 [org.apache.logging.slf4j.Log4jLoggerFactory] 线程“主”java.lang.IllegalArgumentException 中的异常：LoggerFactory 不是 Logback LoggerContext 但 Logback 在类路径上。删除 Logback 或竞争实现（从文件加载的类 org.apache.logging.slf4j.Log4jLoggerFactory：/home/cc-dev/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/ log4j-slf4j-impl/2.17.1/84692d456bcce689355d33d68167875e486954dd/log4j-slf4j-impl-2.17.1.jar）。如果您使用的是 WebLogic，则需要将“org.slf4j”添加到 WEB-INF/weblogic.xml 中的 prefer-application-packages：org.apache.logging.slf4j.Log4jLoggerFactory 在 org.springframework.util.Assert.instanceCheckFailed(Assert.java:637) 在 org.springframework.util.Assert.isInstanceOf(Assert.java:537) 在 org.springframework.boot.logging.logback.LogbackLoggingSystem.getLoggerContext（LogbackLoggingSystem.java:274） 在 org.springframework.boot.logging.logback.LogbackLoggingSystem.beforeInitialize(LogbackLoggingSystem.java:99) 在 org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationStartingEvent（LoggingApplicationListener.java:191） 在 org.springframework.boot.context.logging.LoggingApplicationListener.onApplicationEvent（LoggingApplicationListener.java:170） 在 org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener（SimpleApplicationEventMulticaster.java:172） 在 org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener（SimpleApplicationEventMulticaster.java:165） 在 org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent（SimpleApplicationEventMulticaster.java:139） 在 org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:127) 在 org.springframework.boot.context.event.EventPublishingRunListener.starting（EventPublishingRunListener.java:68） 在 org.springframework.boot.SpringApplicationRunListeners.starting（SpringApplicationRunListeners.java:48） 在 org.springframework.boot.SpringApplication.run(SpringApplication.java:313) 在 net.corda.samples.example.webserver.Starter.main(Starter.java:21)
