不连接到 oracle 可插拔数据库

Question

我想在安装 liquibase 和 sqlcli 后执行“lb generate-schema -split”，但是当我点击上面的命令时，它没有连接到可插拔数据库 (xepdb1)。它总是尝试连接到“xe”或“orcl”服务名称。有人可以帮我解决这个问题吗？

它不连接到可插拔数据库（xepdb1）。它总是尝试连接到“xe”或“orcl”服务名称

正如它所说，曾经是真的，现在不再是真的了。这取决于您如何命名数据库（或留给 Oracle 来决定），而在 newer XE 数据库中它是

xepdb1

.

这是我的 XE 数据库（我知道它的名字；我只是显示我的 TNSNAMES.ORA 中的内容）：

c:\temp>tnsping pdb1

TNS Ping Utility for 64-bit Windows: Version 21.0.0.0.0 - Production on 29-APR-2023 06:27:14

Used parameter files:
C:\Users\littlefoot\Documents\sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = lf_laptop)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XEPDB1)))
OK (60 msec)

看到上一行末尾的

SERVICE_NAME

了吗？

因此，尝试与 Liquibase 相同；我不使用它，所以我无法提供帮助，但我认为应该对此进行修改：

URL           = jdbc:oracle:thin:@localhost:1521/xepdb1
                                                 ------
