java - How to dynamically change Spring JdbcTemplate DataSource? -

i have config file default settings jdbc connection.

is there option edit default connection details once application running? after beans has been created (edit connection details in controller).

scenario:

• user starts application, , can edit connection details going localhost:8080/myapp/db/edit
• fills in connection details , saves new database details

this should find existing connections, update connection details , reinstantiate beans.

you can try removing beans spring container , re initiating them.

    demo demo = getbean(context);      configurablelistablebeanfactory configurablelistablebeanfactory = context             .getbeanfactory();      beandefinitionregistry beandefinitionregistry = (beandefinitionregistry) configurablelistablebeanfactory;     // removing bean container     beandefinitionregistry.removebeandefinition("demo");      // trying obtains bean again container. throw null          demo = getbean(context);     //demo object null here      // creating , registering bean container           beandefinition beandefinition = new rootbeandefinition(demo.class);     beandefinition.setattribute("name", "name");      beandefinitionregistry.registerbeandefinition("demo", beandefinition);     context.refresh();      //obtaining container again     demo = getbean(context);
