Documentation of bind package removal?

[rcollette]

I have a breaking change from 1.5.7.Release to 2.0.0.x where the class PropertySourceUtils is no longer there. Specifically we are using PropertySourceUtils.getSubProperties. However, I don't see any commit that removes the file/class nor do I see any 2.0.0.x release documentation that mentions the removal of this package.

The code was part of Boot 1.5's relaxed binding support which has been rewritten and simplified in 2.0. There is no direct equivalent in 2.0 of the method that you were using.

@rcollette there was a section in the migration guide that I just improved with an explicit reference to the page Andy mentioned.

If that helps, I replaced this code

        RelaxedPropertyResolver resolver = new RelaxedPropertyResolver(context.getEnvironment());
        Map<String, Object> actualSubProperties = resolver.getSubProperties(name);

By binding directly to something like that, depending on the property structure you may need to adapt how the binder is ocnfigured :

        var subProperties = (Map<String, Map<String, String>>)
            Binder.get(context.getEnvironment())
                  .bind(ConfigurationPropertyName.of(name),
                        Bindable.of(ResolvableType.forClassWithGenerics(
                            Map.class,
                            ResolvableType.forClass(String.class),
                            ResolvableType.forClassWithGenerics(
                                Map.class,
                                String.class,
                                String.class))),
                        new IgnoreErrorsBindHandler())
                  .orElse(Collections.emptyMap());
