Postgresql 使用JAVA Web应用程序连接到AWS RDS Postgres

我有一个Web应用程序，它是一个RESTful Web服务。它尝试连接到位于亚马逊云上的Postgres DB。无论何时我有一个请求，它都会尝试使用JPA和Hibernate连接到DB

我在这一行中得到了错误： factory=Persistence.createEntityManagerFactory（“RestWebservicedSaude”）

持久化单元“RestWebServiceIDSaude”的定义如下：

<persistence-unit name="RestWebServiceIDSaude">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>com.tasn.rest.model.PessoaVO</class>

    <properties>

        <property name="hibernate.connection.username" value="postgres"/>
        <property name="hibernate.connection.password" value="*******"/>
        <property name="hibernate.connection.url" value="jdbc:postgresql://tgttgrrgddrdtyoy19w.cj2rnlksrkg4.sa-east-1.rds.amazonaws.com:5432/db"/>
        <property name="hibernate.connection.driver_class" value="org.postgresql.Driver"/>
        <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
        <property name="hibernate.connection.autocommit" value="false"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name ="hibernate.show_sql" value = "true" />

    </properties>

</persistence-unit>

org.hibernate.ejb.HibernatePersistence
com.tasn.rest.model.PessoaVO

无论Web应用程序是在AWS实例中运行还是在我的计算机中运行，我总是会遇到以下错误：

javax.persistence.PersistenceException:无法生成实体管理器工厂。。。 org.hibernate.hibernate异常：无法建立JDBC连接[aascscstrvdvdyoy19w.cj2rnlksrkg4.sa-east-1.rds.amazonaws.com:5432/db]

如果有人能帮我，我将非常感激。请随意询问任何其他代码或其他问题
