How to set application name in a Postgresql JDBC url?
提问by Stephan
I want to set the application name of the connections of my application. So when I list the rows in pg_stat_activity
I can have a non empty application_name
column.
我想设置我的应用程序连接的应用程序名称。所以当我列出行时,pg_stat_activity
我可以有一个非空application_name
列。
I have setup the following JDBC url for connecting to my Postgresql database:
我已经设置了以下 JDBC url 来连接到我的 Postgresql 数据库:
jdbc:postgresql://localhost:5435/MyDB?application-name=MyApp
I have tried also this url with no more success.
我也试过这个网址,但没有成功。
jdbc:postgresql://localhost:5435/MyDB?application_name=MyApp

Looking at the PostgreSQL JDBC 9.1 documentation, connection parameters, the correct property name in the JDBC url is ApplicationName
:
查看PostgreSQL JDBC 9.1 文档,连接参数,JDBC url 中正确的属性名称是ApplicationName
:
ApplicationName = String
Specifies the name of the application that is using the connection. This allows a database administrator to see what applications are connected to the server and what resources they are using through views like
pg_stat_activity
ApplicationName = String
指定使用连接的应用程序的名称。这允许数据库管理员通过类似的视图查看哪些应用程序连接到服务器以及它们正在使用哪些资源
pg_stat_activity
So try:
所以尝试:
jdbc:postgresql://localhost:5435/MyDB?ApplicationName=MyApp
Be aware some comments suggest that this is broken in the 9.1 version driver. Given it is a more than 5 year old version, you should upgrade to a newer version anyway. Check https://jdbc.postgresql.org/for the latest version and use that.
请注意,一些评论表明这在 9.1 版驱动程序中已损坏。鉴于它是一个超过 5 年的旧版本,无论如何您都应该升级到更新的版本。检查https://jdbc.postgresql.org/以获取最新版本并使用它。
