Spring Boot集成Log4j2报错java.lang.NoSuchMethodError: org.apache.logging.log4j.core.config.Configuration

Application startup failed
java.lang.NoSuchMethodError: org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(Lorg/apache/logging/log4j/core/LoggerContext;Lorg/apache/logging/log4j/core/config/ConfigurationSource;)Lorg/apache/logging/log4j/core/config/Configuration;
    at org.springframework.boot.logging.log4j2.Log4J2LoggingSystem.loadConfiguration(Log4J2LoggingSystem.java:176) ~[spring-boot-1.5.8.RELEASE.jar:1.5.8.RELEASE]

spring boot版本为1.5.8，log4j2版本为2.6，同时还有sofarpc版本为1.2.1，网上找了发现是由于jar包冲突，于是我把spring boot从1.3.3改到了1.5.8然而还是没用，求大神解答
