public static void main(String[] args) {
    AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();

    // 扩展 Environment 中的 PropertySources
    // 添加 PropertySource 操作必须在 refresh 方法之前完成
    Map<String, Object> propertiesSource = new HashMap<>();
    propertiesSource.put("user.name", "xiaomage");
    org.springframework.core.env.PropertySource propertySource = new MapPropertySource("first-property-source", propertiesSource);
    context.getEnvironment().getPropertySources().addFirst(propertySource);

    // 注册当前类作为 Configuration Class
    context.register(PropertySourceDemo.class);
    // 启动 Spring 应用上下文
    context.refresh();
    // beanName 和 bean 映射
    Map<String, User> usersMap = context.getBeansOfType(User.class);
    for (Map.Entry<String, User> entry : usersMap.entrySet()) {
        System.out.printf("User Bean name : %s , content : %s \n", entry.getKey(), entry.getValue());
    }
    System.out.println(context.getEnvironment().getPropertySources());
    // 关闭 Spring 应用上下文
