如何外部化standalone.xml？

Question

I am setting up a new server and want to externalize standalone.xml configuration mainly datasource to the properties file so that it can be configured using a properties file. I have used various options like using -P properties flag, still no use. I am using wildfly 10.0 Final. for example from this

<connection-url>jdbc:postgresql://localhost:5432/local_db?currentSchema=something</connection-url>

to this

<connection-url>${connection_url}</connection-url>

Answer 1

To in JBoss you could create a properties file and execute a cli command to read it, for example, creating your datasource.

File

Example of datasource property file:

set ds=TestDB
set dsName=java:jboss/datasources/$ds
data-source add --name=$ds --jndi-name=$dsName --driver-name=example \
    --connection-url="jdbc:example"\
    --user-name="exampleuser"  --password="examplepassword"
echo 'Success'
reload

That can be saved as "file.txt"

File command

Then execute the following cli command:

./jboss-cli.sh --connect --file="file.txt"

Regarding Escape sequence

Be careful regarding the escape sequence, because it changes for the CLI according to the configuration of JBoss and the flag resolve-paramater-values, which if it's set to true tells the CLI to interpret $ instead of just passing it to EAP as is and consequently the escape sequence for --file changes to /$/$.
