Answer 1

最初的项目和新项目之间有一些显著的不同。新项目通过配置类将方面添加到上下文中，而旧（工作）项目通过组件扫描添加方面。切换到方面的组件扫描解决了这个问题。坏：

@Configuration
public class LoggerConfig {

    @Bean
    public SDKProfiler sdkProfiler() { return new SDKProfiler(); }
}

好：

@Configuration
@ComponentScan("com.company.app.logging")
public class LoggerConfig {
} 

其中方面位于com.company.app.logging包中。
