HttpServer.setAttribute介绍

[英]Set a value in the webapp context. These values are available to the jsp pages as "application.getAttribute(name)".
[中]在webapp上下文中设置一个值。这些值作为“application.getAttribute（name）”可用于jsp页面。

/**
 * Set a value in the webapp context. These values are available to the jsp
 * pages as "application.getAttribute(name)".
 * @param name The name of the attribute
 * @param value The value of the attribute
 */
public void setAttribute(String name, Object value) {
 setAttribute(webAppContext, name, value);
}
