Encontrou a solução?

@Artur

Não consegui

Nossa, cara, eu to ficando chateado já.. nenhum moderador pra dar força, e eu já tendei de tudo (que sei pelo menos) pra subir esse projeto.. vinha seguindo a sequencia de aulas da formação Java e desanima parar aqui por conta de uma coisa assim :/

Coisas que eu já tentei:

• Configurar variáveis de ambiente do JAVA_HOME e CATALINA;
• Comentar a linha do mysql Driver/ usar Value para passar a string do driver;(dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");)
• Instalar diversas versões diferentes do mysql;
• Atualizar dependências;
• Downgrade nas dependências;
• Trocar "create-drop" por "update" e "create".

Não adianta entre outros erros, no console aparece:

[...]Error creating bean with name 'getEntityManagerFactory' [....]

E ao acessar no browser o erro 404 segue surgindo... compartilhando aqui pra caso alguém puder ajudar

SOLUCIONADO!

Resolvi mas não sei como exatamente, então fazendo tudo isso sei que no fim deu certo:

• Configurei as variáveis de ambiente do JAVA_HOME e CATALINA;
• Usei o mysql server 5.6;
• Alterei o "log4j.xml" para que ficasse dessa forma:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/doc-files/log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
    debug="true">

    <appender name="stdout" class="org.apache.log4j.ConsoleAppender">
        <param name="Threshold" value="debug" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d{HH:mm:ss} %p [%t]:%c{3}.%M()%L - %m%n" />
        </layout>
    </appender>

    <category name="org.springframework">
        <priority value="warn"/>
        <appender-ref ref="stdout" />
    </category>    

</log4j:configuration>

• Alterei o web.xml para ficar dessa forma:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name>Servlet 3.0 Web Application</display-name>

• Deixei o JpaConfigurator.java dessa forma:

public class JpaConfigurator {

    @Bean
    public DataSource getDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost/projeto_jpa");
        dataSource.setUsername("root");
        dataSource.setPassword("123456789");

        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean getEntityManagerFactory(DataSource dataSource) {
        LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();

        entityManagerFactory.setPackagesToScan("br.com.caelum");
        entityManagerFactory.setDataSource(dataSource);

        entityManagerFactory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());

        Properties props = new Properties();
        props.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL8Dialect");
        props.setProperty("hibernate.show_sql", "true");
        props.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        entityManagerFactory.setJpaProperties(props);
        return entityManagerFactory;
    }

    @Bean
    public JpaTransactionManager getTransactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);

        return transactionManager;
    }

}

• Nas dependencias usei o seguinte mysql

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.47</version>
        </dependency>
