Spring을 사용하지 않고 Heroku에서 PostgreSQL에 어떻게 연결합니까?

Question

나는 Heroku에서 간단한 CRUD 앱을 배포하려고합니다. 그러나 나는 봄을 사용하고 싶지 않다. 내가 사용하고있는 것은 지속성을 위해 JSF (Primefaces)와 JPA (Hibernate)이다. 나는 dB로 연결하기 위해 노력하고 때 나는 다음과 같은 예외를 받고 있어요 :

내의 persistence.xml은 다음과 같습니다

<persistence-unit name="test"> 
<provider>org.hibernate.ejb.HibernatePersistence</provider> 
<properties> 
    <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/> 
    <property name="driverClassName" value="${database.driverClassName}"/> 
    <property name="hibernate.show_sql" value="true"/> 
    <property name="url" value="#{ 'jdbc:postgresql://' + @dbUrl.getHost() + @dbUrl.getPath() }"/> 
    <property name="username" value="#{ @dbUrl.getUserInfo().split(':')[0] }"/> 
    <property name="password" value="#{ @dbUrl.getUserInfo().split(':')[1] }"/> 
    <property name="hibernate.max_fetch_depth" value="3"/> 
    <property name="hibernate.hbm2ddl.auto" value="update"/> 
</properties> 

은 내가 applicationcontext.xml 파일의 속성을 복사 한.

누구나 문제가있을 수 있습니다. ?? 유사한 게시물을 살펴 보았지만 해결책을 찾지 못했습니다.

내 pom.xml 파일은 다음

나 또한 당신과 같은 문제를 통해 지속성 단위의 국지적 위의 구성을 갔다와 pom.xml 파일이 올바르지 만의 ApplicationContext에 실수가있을 수 있습니다. 여기에 포함되지 않은 xml.

다음은 결함이있을 수있는 applictioncontext.xml의 일부입니다.

<bean class="java.net.URI" id="dbUrl"> 
     <constructor-arg value="#{systemEnvironment['DATABASE_URL']}" /> 
    </bean> 

    <bean id="dataSource" 
     class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
     <property name="driverClassName" value="org.postgresql.Driver" />  
     <property name="url" value="#{ 'jdbc:postgresql://' + @dbUrl.getHost() + @dbUrl.getPath() }" /> 
     <property name="username" value="#{ @dbUrl.getUserInfo().split(':')[0] }" /> 
     <property name="password" value="#{ @dbUrl.getUserInfo().split(':')[1] }" /> 
    </bean> 

    <bean id="entityManagerFactory" 
     class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <property name="persistenceUnitName" value="test"/> 
     <property name="dataSource" ref="dataSource" /> 
     <property name="jpaVendorAdapter"> 
      <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> 
       <property name="showSql" value="true" /> 
       <property name="generateDdl" value="true" /> 

       <property name="databasePlatform" value="org.hibernate.dialect.PostgreSQLDialect" /> 
      </bean> 
     </property> 
    </bean>
