Java 将Maven项目部署到Tomcat无法连接到Postgres
我正在尝试将.war文件导入tomcat8 到目前为止，即使Tomcat启动，我也无法访问我的web应用程序的页面。 我从命令systemctl status tomcat8.service中得到这个错误： 几秒钟后：Java 将Maven项目部署到Tomcat无法连接到Postgres,java,postgresql,maven,spring-boot,tomcat,Java,Postgresql,Maven,Spring Boot,Tomcat,我正在尝试将.war文件导入tomcat8 到目前为止，即使Tomcat启动，我也无法访问我的web应用程序的页面。 我从命令systemctl status tomcat8.service中得到这个错误： 几秒钟后： Mar 11 11:25:02 osboxes tomcat8[47998]: at java.util.concurrent.FutureTask.run(FutureTask.java:266) Mar 11 11:25:02 osboxes tomcat8[4799

感谢您的帮助和时间。您的帖子不清楚到底是什么问题，因为您只发布了部分例外情况。您发布的日志条目来自Systemd，它只包括Tomcat日志的一部分。默认情况下，在$CATALINA_BASE/logs中查找Tomcat日志 如果问题确实是缺少驱动程序，您可以通过将驱动程序复制到$CATALINA_BASE/lib目录来确认，重新启动Tomcat以使更改生效
如果确实是这样，并且您希望在应用程序中部署PG-JDBC jar，那么可以通过不同的方式使用Maven，例如，将其添加到资源目录并使用Maven 请在日志中发布异常信息的开头。我添加了日志的开头：您添加了来自Systemd的日志，但它们只包括Tomcat的最后10行左右。查找Tomcat日志并从中发布异常信息。我更新了标题，因为这似乎不是驱动程序问题。我在Tomcat的catalina日志文件中发现了错误：java.sql.SQLException:无法创建PoolableConnectionFactory致命：用户xxxxx的密码身份验证失败我将尝试修复并返回谢谢你，但多亏了你，我才找到了错误的原因@昆汀-太好了！请确保用户名/密码正确，并且Postgres的配置文件pg_hba.conf.Okey中允许使用客户端IP。这肯定是密码，我在conf文件中修复了它，现在我的服务器运行正常，我猜？但我仍然无法访问我的网络应用程序，我还是tomcat的初学者，所以可能我做错了？我将在上面的问题中发布日志，但非常感谢！为了访问tomcat，我需要使用127.0.0.1而不是localhost！再次非常感谢
