PropertySourcesPlaceholderConfigurer works for my @Values but not used for the following advertised datasource configuration

@Bean
@ConfigurationProperties(prefix = "datasource")
public DataSource dataSource() 
 return DataSourceBuilder.create().build();

I customized PropertySourcesPlaceholderConfigurer to decode passwords in configuration file but decoding functionality is not triggered for this exact place, while it works in other places. Could you please advise?

By default Spring will use a simple/non-wrapped ConfigurationPropertySource instead of the more complex PropertySourcesPlaceholderConfigurer, which holds multiple PropertySources.

An example can be found inside DataSourceBuilder itself

private void bind(DataSource result) 
 ConfigurationPropertySource source = new MapConfigurationPropertySource(this.properties);
 ConfigurationPropertyNameAliases aliases = new ConfigurationPropertyNameAliases();
 aliases.addAliases("url", "jdbc-url");
 aliases.addAliases("username", "user");
 Binder binder = new Binder(source.withAliases(aliases));
 binder.bind(ConfigurationPropertyName.EMPTY, Bindable.ofInstance(result));

For that snippet, normally this.properties is populated using the DataSourceProperties Bean, which is a @ConfigurationProperties annotated class

@ConfigurationProperties(prefix = "spring.datasource")
public class DataSourceProperties implements BeanClassLoaderAware, InitializingBean {

---

The thing is, @ConfigurationProperties map 1:1 to a properties file, it is very opinionated.
@Value is a different beast.

---

I tackled a completely custom implementation in this answer.

You might find it valuable.
