Hello,

I guess this is a bug in STS (2.6.1), I get a "Spring Beans Problem" when having a static method annotated with @Bean, but if you look into the @Bean-javadoc you see that this is the suggested approach for BeanFactoryPostProcessors.

I have a @Configuration class like this:

Code:
@Configuration
public class DataConfig {

	@Value("${jdbc.url}") String url;
	@Value("${jdbc.username}") String username;
	@Value("${jdbc.password}") String password;

	@Bean
	public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer(){
		PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
		propertySourcesPlaceholderConfigurer.setLocation(new ClassPathResource("database.properties"));
		return propertySourcesPlaceholderConfigurer;
	}

	@Bean
	public DataSource dataSource(){
		BasicDataSource dataSource = new BasicDataSource();
		dataSource.setUrl(url);
		dataSource.setUsername(username);
		dataSource.setPassword(password);
		return dataSource;
	}
	
	@Bean
	public PlatformTransactionManager transactionManager(){
		return new DataSourceTransactionManager(dataSource());
	}

}
The "Spring Bean Problem" is on the method propertySourcesPlaceholderConfigurer() and tells me that the method must not be private, static or final.

However, the configuration class compiles and works fine in tests. The red problem sign is just annoying.
