Springboot整合log4j2-问题与配置

问题总结 :
1.Springboot 自身拥有日志记录jar : spring-boot-starter-logging ,首先排除loggin jar包;
2.启动报错说明

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/tony/.m2/repository/ch/qos/logback/logback-classic/1.2.3/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/C:/Users/tony/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.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 [ch.qos.logback.classic.util.ContextSelectorStaticBinder]

**
报错说明:这是因为与logback的冲突并未解决，导致启动失败，根据上面的报错信息，找到logback-classic-1.2.3.jar和slf4j-log4j12-1.7.25.jar的相应位置删除，并在pom.xml中加入如下排除代码：

     
            org.springframework.boot
            spring-boot-starter-web
            
            
                
                    org.springframework.boot
                    spring-boot-starter-logging
                
                
                    org.slf4j
                    slf4j-log4j12
                
            
        

3.mybatis 与 log4j2 日志冲突,特此记录,加入以下jar包 ,会2.出错误
还未找到解决方案 ,应该与logback有关

org.mybatis.spring.boot
mybatis-spring-boot-starter
2.0.0

整体框架配置如下 :

1.pom.xml配置

2.log4j2配置文件,跟据不同级别错误生成日志文件

    
        
        
        
         D://log4j2Logs

3.application.properties 中配置指向

logging.config= classpath:log4j2.xml
