具有自定义配置的 Spring Boot 应用程序不会在服务器（WebSphere）启动时加载

Question

我有一个使用 mybatis 连接到两个数据源的 spring boot 应用程序。 Spring boot 在服务器启动时不加载，我在服务器启动期间检查了日志，但在其中没有看到任何与 Spring Boot 相关的消息。服务器启动后，应用程序状态在 WAS 控制台中显示为 Started。

应用程序在我重新启动之前无法工作，并且在应用程序重新启动期间，我可以在日志中看到 spring boot 相关消息。该应用程序在重新启动后运行良好。

服务器版本：IBM WebSphere Application Server Network Deployment (8.5.5.14) Java 版本：8.0.2.10（IBM WebSphere SDK Java 技术版）

@SpringBootApplication
@ComponentScan(basePackages="org.sample.solve.*")
@MapperScan("org.sample.solve.sa.db.mappers")
public class SampleApplication {
    public static void main(String[] args) {
        SpringApplication.run(SampleApplication.class, args);
    }
}

配置：

package org.sample.solve.sa;

import .....

@Configuration
public class MybatisDBConfig  {

    private final Logger log = LoggerFactory.getLogger(this.getClass());
    public static final String SQL_SESSION_FACTORY_NAME_1 = "sqlSessionFactory1";

    public static final String MAPPERS_PACKAGE_TSC      = "org.sample.solve.sa.db.mappers"; // mapper interface package

我正在使用 servlet 初始化程序设置活动配置文件。

我在尝试创建计划作业（服务器中的 Spring Boot 应用程序）时也注意到了同样的情况。直到我通过调用休息服务或做其他事情来戳应用程序时，这项工作才开始。不幸的是，我不知道该怎么做才能让它工作。
