JBoss AS / Wildfly中的多用户数据库连接池

Question

I'm working on web application, that need access to postgresql database.

For some reason, i need to establish individual connection, for every authenticated user.

My current datasource setup looks like this:

<datasource jndi-name="java:jboss/ds" pool-name="ds-pool" enabled="true">
                    <connection-url>jdbc:postgresql://192.168.1.2:5432/springdb</connection-url>
                    <driver>postgresql-driver</driver>
                    <pool>
                        <min-pool-size>5</min-pool-size>
                        <max-pool-size>30</max-pool-size>                       
                    </pool>
                    <security>
                        <user-name>postgres</user-name>
                        <password>postgres</password>
                    </security>
                </datasource>

In java code i do this:

@Resource(lookup = "java:jboss/ds")
DataSource ds;
conn = ds.getConnection(username, password);

And here is the problem. Every getConnection call produce following WARN in jboss console:

> 14:07:48,665 WARN

I've tried to add allow-multiple-users to pool configuration, but in jboss 7 i'm getting xml parse error, and in wildfly 8 it does nothing.

So is there any way to get multiple users connection pool in jboss?

Answer 1

It seems that I figured it out. So to enable multiple users in a connection pool, you need to add the following in the datasource definition:

<allow-multiple-users>true</allow-multiple-users>

instead of:

<allow-multiple-users/>
