Erro ao tentar iniciar o projeto

Ao criar o projeto e iniciar o tomcat dá erro. Está criado o banco no mysql mas, não tem as tabelas. A conexão com o banco foi alterada para informar a senha.

@Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        dataSource.setUrl("jdbc:mysql://localhost:3306/casadocodigo?autoReconnect=true&useSSL=false");
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        return dataSource;
    }

Tentei rodar o projeto no eclipse e no intellij e ambos estão dando o mesmo erro.
