3、修改spring boot版本为2.3.0.RELEASE,修改mysql版本为5.1.47，刷新maven。修改后的pom文件如下：

    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.3.0.RELEASE
         
    
    com.example
    starter
    0.0.1-SNAPSHOT
    00Starter
    Demo project for Spring Boot
    
        1.8
    
    
        
            org.springframework.boot
            spring-boot-starter-web
        

        
            mysql
            mysql-connector-java
            runtime
            5.1.47
        
        
            org.projectlombok
            lombok
            true
        
        
            org.springframework.boot
            spring-boot-starter-test
            test
        
    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
                
                    
                        
                            org.projectlombok
                            lombok
                        
                    
                
            
        
    

4、运行application，控制台信息如下：

 /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \

  '  |____| .__|_| |_|_| |_\__, | / / / /
 =========|_|==============|___/=/_/_/_/
