overrule PropertyOverrideConfigurer bean in code

[Dave Syer]

This works for me (with your configuration from the poc archive you posted):

        GenericApplicationContext context = new GenericApplicationContext();
        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(context);
        reader.loadBeanDefinitions(new ClassPathResource(SPRING_CONTEXT_PATH));
        PropertyOverrideConfigurer cfg = new PropertyOverrideConfigurer();
        cfg.setLocation(new ClassPathResource(ClassUtils.addResourcePathToPackagePath(OverridePropertiesPocTests.class, "dev/overridePropertiesPoc.properties")));
        cfg.setOrder(2);
        context.getBeanFactory().registerSingleton("override", cfg);
        context.refresh();
        PocBean pocBean = (PocBean) context.getBean(BEAN_ID, PocBean.class);
        assertEquals("value from dev properties", pocBean.getName());

But maybe it should be easier. Remind me: why do you need to do the override programmatically?

Genius, it works! Thx for the effort.

We set this programmatically at runtime to reuse the same Spring config for different behaviours.

[Dave Syer]

But if all you are doing is switching the location of a properties file at runtime you can do that with a simple PropertyPlaceholderConfigurer?

[Snow]

The poc example doesn't show the full context of our situation here where several Spring config files come into play. There's already a PropertyPlaceHolder in one of the configs, overriden by a PropertyOverrider in another config and we wanted to override that once more.

We couldn't change any of the included Spring config files, because they belong to another API.
