If you have as much distaste for XML configuration as I do, then fear no more! Do away with your JPA implementation and persistence.xml and move configuration in to code. Since the configurations are supplied by Provider objects, how you obtain the configuration data is up to you (read from file, obtain from consul, whatever your heart desires).

Trivial Example

    public void configure() {
        install(new HibernatePersistModule());

        bind(HibernateEntityClassProvider.class).toInstance(new HibernateEntityClassProvider() {
            @Override
            public List<Class<? extends Object>> get() {
                return Arrays.asList(Account.class);
            }
        });

        bind(HibernatePropertyProvider.class).toInstance(new HibernatePropertyProvider() {
            @Override
            public Map<String, String> get() {
                final Map<String, String> properties = new HashMap<>();
                properties.put("hibernate.connection.driver_class", "com.mysql.cj.jdbc.Driver");
                properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
                properties.put("hibernate.connection.url", "jdbc:mysql://127.0.0.1/p_user?useSSL=false");
                properties.put("hibernate.connection.username", "root");
                properties.put("hibernate.connection.password", "password");
                return properties;
            }
        });
    }
