springboot配置log4j2报错：java.lang.IllegalStateException: Logback configuration error detected:_exception in thread "main" java.lang.illegalstatee

引入log4j2后启动报错。

经查找原因：是由于引入的log4j2和spring-boot-starter-web默认的日志配置冲突。

解决方法：
将spring-boot-starter-web默认的日志排除掉：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
