java - Spring Boot AuthenticationFilterConfiguration.onStartup 未调用

Question

我有以下配置类:

@Configuration
public class AuthenticationFilterConfiguration extends SpringBootServletInitializer {

    private static final Logger LOGGER = LoggerFactory.getLogger(AuthenticationFilterConfiguration.class);

    public AuthenticationFilterConfiguration(){
        LOGGER.info("Setting up authentication filter");
    }

    @Override
    public void onStartup(ServletContext context) throws ServletException {
        super.onStartup(context);
        LOGGER.info("Authentication filter configured");
    }

}

这与主应用程序位于同一包中:

@SpringBootApplication
public class MainApplication {
    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class, args);
    }
}

在我的日志中 - 我看到:

2018-04-10 AuthenticationFilterConfiguration : Setting up authentication filter

但是，我从未看到来自 onStartup(...) 的日志消息方法说 Authentication filter configured 。我的另一个@Configuration正在加载类(它们创建了很多 @Bean )

为什么onStartup方法没有被调用？其他一切都正常，我的 RESTful 端点正在工作，等等......

Answer 1

结果我需要实现 ServletContextInitializer 而不是 Spring Boot 类。这工作得很好:

@Configuration
public class AuthenticationFilterConfiguration implements ServletContextInitializer {

    private static final Logger LOGGER = LoggerFactory.getLogger(AuthenticationFilterConfiguration.class);

    public AuthenticationFilterConfiguration(){
        LOGGER.info("Setting up authentication filter");
    }

    @Override
    public void onStartup(ServletContext context) throws ServletException {
        LOGGER.info("Authentication filter configured");
    }

}
