SpringBoot项目修改内置tomcat版本

覆盖掉tomcat版本

    8.5.51



    org.apache.tomcat.embed
    tomcat-embed-core
    ${tomcat.version}


    org.apache.tomcat
    tomcat-juli
    ${tomcat.version}

忽略掉spring-boot-starter-web里的tomcat

    org.springframework.boot
    spring-boot-starter-web
    
        
            org.springframework.boot
            spring-boot-starter-tomcat
        
    

如果不忽略内置toncat会报以下错误，jar包冲突
