【问题描述】：
我使用 jhipster 创建我的项目，并尝试使用 mvn install 命令创建一个战争。战争成功创建，但是当我尝试使用 java -jar 命令运行战争时，我收到多个 SLF4J 错误。然而，该项目在 Eclipse 中运行良好。
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Volumes/Permanent/Workspace/sample-app/target/sample-app-0.0.1-SNAPSHOT.war!/WEB-INF/lib/log4j-slf4j-impl-2.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Volumes/Permanent/Workspace/sample-app/target/sample-app-0.0.1-SNAPSHOT.war!/WEB-INF/lib/logback-classic-1.1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

这是 pom.xml 的一部分，我曾尝试排除 spring-boot-logging，但它不起作用。不知道对不对。
