Conection com banco de dados não funciona

Olá, implementei minha JPAConfiguration mas ao subir o servidor da erro 500 ao conectar com o banco de dados "javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Could not open connection"

minha classe

package br.com.notus.conf;

import java.util.Properties;

import javax.persistence.EntityManagerFactory;

import org.springframework.context.annotation.Bean;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableTransactionManagement
public class JPAConfiguration {

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factorBean = new LocalContainerEntityManagerFactoryBean();
        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();

        factorBean.setJpaVendorAdapter(vendorAdapter);

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUsername("root");
        dataSource.setPassword("admin");
        dataSource.setUrl("jdbc:msysql://localhost:3007/notus");
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");

        factorBean.setDataSource(dataSource);

        Properties prop = new Properties();
        prop.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        prop.setProperty("hibernate.show_sql", "true");
        prop.setProperty("hibernate.hbm2ddl.auto", "update");

        factorBean.setJpaProperties(prop);

        factorBean.setPackagesToScan("br.com.notus.models");

        return factorBean;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
        return new JpaTransactionManager(emf);
    }
}

OBS: A porta quando eu criei o banco de dados utilizei a 3007 mesmo, pois a 3006 já estava sendo utilizada por outro projeto meu.
