我的应用程序尝试使用 Jdbc 驱动程序版本连接到 PostgreSQL 时遇到一个奇怪的问题：8.4-702.jdbc4

似乎找不到它所在的 persistence.xml 中定义的数据库。

错误：

[INFO] Caused by: org.postgresql.util.PSQLException: FATAL: database "mydb" does not exist
[INFO]  at org.postgresql.core.v3.ConnectionFactoryImpl.readStartupMessages(ConnectionFactoryImpl.java:464)

但是，我可以在 shell 中做到这一点而不会出现问题：

$ psql -U postgres -h 192.168.145.128

持久性.xml

  <properties>
     <property name="hibernate.hbm2ddl.auto" value="update"/>
     <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://192.168.145.128:5432/mydb" />
     <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver" />
     <property name="javax.persistence.jdbc.user" value="postgres" /> 
     <property name="javax.persistence.jdbc.password" value="postgres" /> 
  </properties>

可能是什么问题呢？

就我而言，这是因为提供了错误的用户名和密码。
