SchemaSpy PostgreSQL - 警告 - 连接失败 [英] SchemaSpy PostgreSQL - WARN - Connection Failure

问题描述

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 容器上运行，所以我将端口转发到 5431)

我的 schemaspy.properties 文件是:

# 数据库类型.使用 -dbhelp 运行以获取详细信息schemaspy.t=pgsql# 替代 jdbc 驱动程序的可选路径.# 数据库属性:主机、端口号、用户名、密码schemaspy.host=localhost:5431schemaspy.port=5431schemaspy.db=dbnameschemaspy.u=dbuserschemaspy.p=dbpassword# 输出目录保存生成的文件schemaspy.o=dbschema# 生成图表的数据库方案schemaspy.s=public

当我运行这个命令时:

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

我确信可以在 lcoalhost:5431 上访问数据库.但是我收到:

<前>user@hostname:~/path-to-app$ java -jar schemaspy-6.0.0.jar -configFile schemaspy.properties____ _ ____/___|___||__ ___ _ __ ___ __ _/___|_ _ _ _\___ \/__|'_ \/_ \ '_ ` _ \/_` \___ \|'_ \||||___) |(__| | | | __/| | | | (_| |___) | |_) ||_|||____/\___|_||_|\___|_||_||_|\__,_|____/|.__/\__, ||_||___/6.0.0SchemaSpy 生成数据库模式关系的 HTML 表示.SchemaSpy 绝对没有任何保证.SchemaSpy 是免费软件，可以在 LGPL 版本 3 或更高版本的条件下重新分发.http://www.gnu.org/licenses/信息 - 在 PID 为 18555 的主机名上启动 Main v6.0.0(/home/user/path-to-app/schemaspy-6.0.0.jar 由用户在/home/user/path-to-app 中启动)信息 - 以下配置文件处于活动状态:默认信息 - 找到配置文件:schemaspy.properties信息 - 在 3.406 秒内启动 Main(JVM 运行 4.519)信息 - 开始模式分析警告 - 连接失败

我应该添加驱动程序吗?我尝试使用 postgresql-42.2.4.jar.我从 jdbc.postgresql.org 站点下载了它，并将这一行添加到配置文件中.

schemaspy.dp=postgresql-42.2.4.jar

但是它仍然显示相同的错误.

解决方案

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

# 数据库类型.使用 -dbhelp 运行以获取详细信息schemaspy.t=pgsql# 替代 jdbc 驱动程序的可选路径.schemaspy.dp=postgresql-42.2.4.jar# 数据库属性:主机、端口号、用户名、密码schemaspy.host=localhost:5431schemaspy.port=5431schemaspy.db=dbnameschemaspy.u=dbuserschemaspy.p=dbpassword# 输出目录保存生成的文件schemaspy.o=/home/user/dump# 生成图表的数据库方案schemaspy.s=public

并且工作正常.

I try to connect to my PostgresSQL server using SchemaSpy. I installed Java using oracle-java8-installer from ppa:webupd8team/java.

(My PostgreSQL server works on Docker container so I forward port to 5431)

My schemaspy.properties file is:

# 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

When I run this command:

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

I'm sure that database is reacheable on lcoalhost:5431. However I receive:

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

                                              6.0.0

Should I add a driver? I tried with postgresql-42.2.4.jar. I downloaded it from jdbc.postgresql.org site and added this line to config file.

schemaspy.dp=postgresql-42.2.4.jar

However it still shows the same error.

解决方案

Ok I finally know what was the problem. This line schemaspy.dp=postgresql-42.2.4.jar should be added directly after definition of type of database. Now my schemaspy.properties file is:

# 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

And works properly.
