Spring中ClassPathXmlApplication与FileSystemXmlApplicationContext的区别以及ClassPathXmlApplicationContext 的具 _Application

君不见长松卧壑困风霜，时来屹立扶明堂。这篇文章主要讲述Spring中ClassPathXmlApplication与FileSystemXmlApplicationContext的区别以及ClassPathXmlApplicationContext 的具相关的知识，希望能为你提供帮助。

一、ClassPathXmlApplicationContext 的具体路径

String s[] = System.getProperty("java.class.path").split("; ");
for (String string : s) {
System.out.println(string);
}

排除掉lib以及C盘的，最后指向的是 ../target/classes/

所以把spring的xml放到main/resources下，Build--> make project（ctrl+F9）一下，即可在target生成，这时候使用以下语句就可以了

ApplicationContext bf = new ClassPathXmlApplicationContext("applicationContext.xml");

二、ClassPathXmlApplicationContext 使用方法

public void testBean(){ //单配置文件方式一 BeanFactory beanFactory=new ClassPathXmlApplicationContext("applicationContext.xml"); //单配置文件方式二 BeanFactory beanFactory=new ClassPathXmlApplicationContext("classpath:applicationContext.xml"); //多个配置文件 BeanFactory beanFactory=new ClassPathXmlApplicationContext(new String[]{"applicationContext.xml"}); //绝对路径需加“ file:” 前缀 BeanFactory beanFactory = new ClassPathXmlApplicationContext("file:E:\Workspace\idea_workspace\spring\springtest\src\main\resources\applicationContext.xml"); TestBean bean= (TestBean) beanFactory.getBean("testBean"); assertEquals("testStr",bean.getTestStr()); }

三、FileSystemXmlApplicationContext使用方法

public void testBean(){
//项目根目录 BeanFactory beanFactory=new FileSystemXmlApplicationContext("applicationContext.xml");

//classes目录 BeanFactory beanFactory=new FileSystemXmlApplicationContext("classpath:applicationContext.xml");

//项目路径相对路径 BeanFactory beanFactory=new FileSystemXmlApplicationContext("src\\main\\resources\\applicationContext.xml"); //多配置文件 BeanFactory beanFactory=new FileSystemXmlApplicationContext(new String[]{"src\\main\\resources\\applicationContext.xml"}); //绝对目录 BeanFactory beanFactory=new FileSystemXmlApplicationContext(new String[]{"E:\\Workspace\\idea_workspace\\spring\\springtest\\src\\main\\resources\\applicationContext.xml"}); TestBean bean= (TestBean) beanFactory.getBean("testBean"); assertEquals("testStr",bean.getTestStr()); }
