PostgreSQL™ includes one implementation of ConnectionPoolDataSource named
org.postgresql.ds.PGConnectionPoolDataSource.
JDBC requires that a ConnectionPoolDataSource be configured via JavaBean
properties, shown in Table 11.1, “ConnectionPoolDataSource Configuration Properties”,
so there are get and set methods for each of these properties.
Table 11.1. ConnectionPoolDataSource Configuration Properties
| Property | Type | Description |
|---|---|---|
| serverName | STRING | PostgreSQL™ database server host name |
| databaseName | STRING | PostgreSQL™ database name |
| portNumber | INT | TCP port which the PostgreSQL™ database server is listening on (or 0 to use the default port) |
| user | STRING | User used to make database connections |
| password | STRING | Password used to make database connections |
| ssl | BOOLEAN | If `true`, use SSL encrypted connections (default `false`) |
| sslfactory | STRING | Custom `javax.net.ssl.SSLSocketFactory` class name (see the section called [“Custom SSLSocketFactory”](ssl-factory.html)) |
| defaultAutoCommit | BOOLEAN | Whether connections should have autocommit enabled or disabled when they are supplied to the caller. The default is `false`, to disable autocommit. |
Many application servers use a properties-style syntax to configure these properties, so it would not be unusual to enter properties as a block of text. If the application server provides a single area to enter all the properties, they might be listed like this:
serverName=localhost
databaseName=test
user=testuser
password=testpassword
Or, if semicolons are used as separators instead of newlines, it could look like this:
serverName=localhost;databaseName=test;user=testuser;password=testpassword
