package com; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringExam { public static void main(String[] args) { ApplicationContext applicationContext= new ClassPathXmlApplicationContext ("com/applicationContext.xml"); String path = SpringExam.class.getCanonicalName(); System.out.println(path); } }
配置文件路径带包名,这个是相对于编译后的 classpath
第二种方式用filesystem...
public static void main(String[] args) { ApplicationContext applicationContext= // new ClassPathXmlApplicationContext ("com/applicationContext.xml"); new FileSystemXmlApplicationContext ("src/com/applicationContext.xml"); String path = SpringExam.class.getCanonicalName(); System.out.println(path); }
这个路径要加上src,也不知道为啥
第三个方式
new FileSystemXmlApplicationContext ("file:D:\\workspace\\j2ee\\springdemo\\src\\com\\applicationContext.xml");
第四个方式
new FileSystemXmlApplicationContext ("D:\\workspace\\j2ee\\springdemo\\src\\com\\applicationContext.xml");

property文件要在src根目录下才行
