Conflict between log4j and logback of SpringBoot framework to build error records

[Question]: Spring boot integrates log4j to solve the conflict with logback

[the reason]:

This is because the conflict with logback has not been resolved, resulting in startup failure.

[Solution]:

According to the above error message, find the corresponding positions of logback-classic-1.2.3.jar and slf4j-log4j12-1.7.25.jar and delete them, and add the following exclusion code in pom.xml:

<dependency>           
    <groupId>org.springframework.boot</groupId>    
        <artifactId>spring-boot-starter-web</artifactId>       
        <!-- 排除默认的logback日志，使用log4j-->          
        <exclusions>              
            <exclusion>                  
                <groupId>org.springframework.boot</groupId>          
                <artifactId>spring-boot-starter-logging</artifactId>                
            </exclusion>              
        <exclusion>      
            <groupId>org.slf4j</groupId>  
                  <artifactId>slf4j-log4j12</artifactId>        
            </exclusion>  
        </exclusions>     
</dependency>

Start found that everything is normal, so far, the configuration of log4j is complete.
