Mybatis hybrid configuration system - mybatis

Question

I am writing a CLI app with Mybatis. In my app, when i go to different menus, it prompts for the user and password for the particular database that menu goes against.
I want to use Guice and Mybatis to handle all this but i have a slight problem. I want to use the XML config file to handle the mybatis config per database, but the user and pass from each connection has to come from the UI. So basically, i want to load mybatis xml file for a particular connection, then insert the credentials for the particular connection the user typed in, then bind those to the guice injector for that set of menus.
I can do it in java with a property object pretty easy, but i can't figure out how to do it with loading the XML first, then augmenting it with certain settings before loading.
Has anyone tried this?

Answer 1

If you are using mybatis guice this can be done by providing your dataSourceProvider for MyBatisModule like this:
Class<? extends Provider<DataSource>> dataSourceProviderType = YourDataSourceProvider.class;
Injector injector = Guice.createInjector(
new MyBatisModule() {
#Override
protected void initialize() {
bindDataSourceProviderType(dataSourceProviderType);
// other initialization ...
}
},
// other modules
);
YourDataSourceProvider should be able to create DataSource using credentials gotten from UI.
In this case you still can use xml mappers for mybatis.
