spring-boot-configuration-processor是否处理带注释的bean方法？

Question

Does spring-boot-configuration-processor process annotated bean methods? Because in my case, it doesn't.

Here is my code:

@Data
public class DatasourceConnectionPoolProperties {
  private Integer initialSize;
  private Integer maxIdle;
  private Integer minIdle;
  private Integer timeBetweenEvictionRunsMillis;
  private Integer minEvictableIdleTimeMillis;
  private Boolean testOnBorrow;
  private String validationQuery;
}

And somewhere in @Configuration-annotated class:

@Bean
@ConfigurationProperties("persistence.pool")
protected DatasourceConnectionPoolProperties localPoolProperties() {
  return new DatasourceConnectionPoolProperties();
}

During compilation, no metadata generated. But, when DatasourceConnectionPoolProperties gets annotated with @ConfigurationProperties metadata generated.

Did I make mistake somewhere, or it's just spring-boot-configuration-processor limitations?

它可以，但是注释处理器仅查找public方法，而您的则protected （顺便说一句，对于@Bean方法，这是非常不寻常的）。
