Java 为什么Tomcat使用反射进行Catalina实例化
阅读Tomcat 7源代码,我只是想知道为什么Tomcat实例Catalina并通过使用反射调用相关方法,而不是简单地使用Java 为什么Tomcat使用反射进行Catalina实例化,java,tomcat,reflection,Java,Tomcat,Reflection,阅读Tomcat 7源代码,我只是想知道为什么Tomcat实例Catalina并通过使用反射调用相关方法,而不是简单地使用new来创建对象并直接调用方法?答案在Bootstrap类的javadoc注释中: /** * Bootstrap loader for Catalina.

来创建对象并直接调用方法?答案在Bootstrap
类的javadoc注释中:
/**
* Bootstrap loader for Catalina. This application constructs a class loader
* for use in loading the Catalina internal classes (by accumulating all of the
* JAR files found in the "server" directory under "catalina.home"), and
* starts the regular execution of the container. The purpose of this
* roundabout approach is to keep the Catalina internal classes (and any
* other classes they depend on, such as an XML parser) out of the system
* class path and therefore not visible to application level classes.

你能把我们链接到相关的源代码吗?在不相关的新闻中:我真的很喜欢“instancilization”这个词,并会尝试将它作为我的活动词汇表的一部分。请看:Class startupClass=catalinaLoader.loadClass(“org.apache.catalina.startup.catalina”);对象startupInstance=startupClass.newInstance();
