将 Heroku Spring 应用程序从 Java 7 升级到 Java 11，JDBC 无法再连接到 PostgreSQL

【问题标题】：Upgrading Heroku Spring app from Java 7 to Java 11, JDBC is not able to connect to PostgreSQL anymore将 Heroku Spring 应用程序从 Java 7 升级到 Java 11，JDBC 无法再连接到 PostgreSQL
【发布时间】：2021-03-14 15:35:43
【问题描述】：

我正在尝试将我的 Heroku 应用程序从 Java 7 升级到 11。以前，在 Java 7 版本中一切正常。由于 Heroku 现在强制所有连接到 PostgreSQL 的应用程序使用 sslmode=require，我必须升级我的 pom.xml PostgreSQL JDBC 驱动程序版本以适应 Heroku 最新的，我相信是 PostgreSQL 13。

所以我采取的步骤是：

  1. 用新的依赖更新了我的 pom.xml，我相信这些是需要更新的相关依赖：

    <dependency>
    <groupId>org.hsqldb</groupId>
    <artifactId>hsqldb</artifactId>
    <version>2.2.8</version>
</dependency>
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.1.4</version>
</dependency>
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-dbcp2</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>3.6.10.Final</version>
</dependency>

  2. 还有我的dispatcher-servlet.xml 配置（关注https://devcenter.heroku.com/articles/heroku-postgresql#heroku-postgres-ssl）：

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

    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">
        <property name="url" value="#{ 'jdbc:postgresql://' + @dbUrl.getHost() + ':' + @dbUrl.getPort() + @dbUrl.getPath() + '?sslmode=require' }"/>
        <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="dataSource" ref="dataSource"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>
        </property>
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <!-- change this to 'verify' before running as a production app -->
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
    </bean>
</beans>

  3. 还有system.properties

    java.runtime.version=11

但是，它给出了错误：

按照 Flame239 的建议更新 Maven 依赖项后更新错误：

pom.xml 如下所示：

还有其他建议吗？

【问题讨论】：

  • 您的新错误似乎表明您的 Hibernate 版本与您引入的 javax.persistence/jakarta.persistence 依赖项之间不匹配。但是，鉴于您收到了原始问题的答案，您应该问一个新问题与你的新问题。
  • 实际上经过一番挖掘，这是从 java 7 升级到 java 8 的问题。请参阅stackoverflow.com/questions/66628051/… ...在这篇文章中，我的设置解决了 heroku postgres 的 JDBC 连接问题，但仍然存在 JSP 渲染问题...如果有人可以建议，请跳到这篇文章。谢谢
  • @sefirosu 如果我的回答解决了您的问题，请将其标记为已接受

标签： java spring-boot jdbc heroku-postgres dispatch


【解决方案1】：

正如错误所说：java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

简而言之：在 Java 9 中，JAXB API 已从 JDK 中删除，因此您必须手动添加此依赖项

This question 将提供更多详细信息。

Here 你会发现如何在 spring 中修复它，他们建议添加这个依赖：

<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
</dependency>
