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());
}
