java - SchemaSpy PostgreSQL - 警告 - 连接失败

Question

我尝试使用 SchemaSpy 连接到我的 PostgresSQL 服务器。我使用 ppa:webupd8team/java 中的 oracle-java8-installer 安装了 Java。

(我的 PostgreSQL 服务器在 Docker 容器上工作，所以我将端口转发到 5431)

我的 schemaspy.properties 文件是:

# type of database. Run with -dbhelp for details
schemaspy.t=pgsql
# optional path to alternative jdbc drivers.
# database properties: host, port number, name user, password
schemaspy.host=localhost:5431
schemaspy.port=5431
schemaspy.db=dbname
schemaspy.u=dbuser
schemaspy.p=dbpassword
# output dir to save generated files
schemaspy.o=dbschema
# db scheme for which generate diagrams
schemaspy.s=public

当我运行这个命令时:

java -jar schemaspy-6.0.0.jar -configFile schemaspy.properties

我确定可以在 lcoalhost:5431 上访问数据库。但是我收到:

user@hostname:~/path-to-app$ java -jar schemaspy-6.0.0.jar -configFile schemaspy.properties

                                             |_|    |___/

                                              6.0.0

我应该添加驱动程序吗？我尝试使用 postgresql-42.2.4.jar。我是从jdbc.postgresql.org下载的站点并将此行添加到配置文件。

schemaspy.dp=postgresql-42.2.4.jar

但是它仍然显示相同的错误。

Answer 1

好吧，我终于知道问题出在哪里了。这行 schemaspy.dp=postgresql-42.2.4.jar 应该直接添加到数据库类型的定义之后。现在我的 schemaspy.properties 文件是:

# type of database. Run with -dbhelp for details
schemaspy.t=pgsql
# optional path to alternative jdbc drivers.
schemaspy.dp=postgresql-42.2.4.jar
# database properties: host, port number, name user, password
schemaspy.host=localhost:5431
schemaspy.port=5431
schemaspy.db=dbname
schemaspy.u=dbuser
schemaspy.p=dbpassword
# output dir to save generated files
schemaspy.o=/home/user/dump
# db scheme for which generate diagrams
schemaspy.s=public

并且正常工作。
