springContextHolder

SpringContextHolder is a class in the Spring Framework that provides access to the current context of the Spring application. It is typically used in web applications to access the Spring ApplicationContext, which contains information about the configuration, beans, and other objects managed by Spring.

The SpringContextHolder class provides a static method to access the current context:

public class SpringContextHolder {
    private static ApplicationContext context;

    public static void setContext(ApplicationContext context) {
        SpringContextHolder.context = context;
    }

    public static ApplicationContext getContext() {
        return context;
    }
}

The `setContext` method is used to set the current context of the application, while the `getContext` method is used to retrieve it. The context is typically set during application startup or initialization, and then accessed throughout the application as needed.

Note that the SpringContextHolder class is not thread-safe, so it should be used carefully in multi-threaded environments. In general, it is recommended to avoid using static variables or methods in Spring applications, and instead rely on dependency injection and other mechanisms provided by the framework.

springcontextholder.getbean

springcontextholder.getbean是Spring框架中的一个静态方法，用于获取指定名称的Bean实例。它可以在任何地方调用，无需通过注入或其他方式获取ApplicationContext实例。该方法需要传入一个String类型的参数，即Bean的名称，返回一个Object类型的实例。使用该方法可以方便地获取Spring容器中的Bean实例。
