java - Error starting Application Context in Spring Boot

Answer



I'm very new to Spring Boot.




This is my pom.xml:




    
        org.springframework.boot
        spring-boot-starter-data-jpa
    
    
        org.projectlombok

        lombok
        true
    
    
        org.springframework.boot
        spring-boot-starter-thymeleaf
    
    
        org.springframework.boot
        spring-boot-starter-web

    
    
        org.webjars
        bootstrap
        3.3.7
    
    
        org.hibernate
        hibernate-entitymanager
        5.2.3.Final

    
    
        org.springframework.boot
        spring-boot-devtools
        runtime
    
    
        org.springframework.boot
        spring-boot-starter-test
        test

    
    
        org.projectlombok
        lombok
        1.16.20
    
    
        mysql
        mysql-connector-java
        5.1.46

    
    
        org.slf4j
        jul-to-slf4j
        1.7.25
    
    
        javax.validation
        validation-api
        2.0.1.Final

    
    
        org.springframework.boot
        spring-boot-starter-jdbc
    
    
        com.h2database
        h2
        runtime




So I can see this error:
