配置文件放在class目录下:
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring.xml");
WEB-INF下:
ApplicationContext applicationContext = new FileSystemXmlApplicationContext("WebRoot/WEB-INF/spring.xml");
多个文件可用*表示
ApplicationContext applicationContext = new FileSystemXmlApplicationContext("WebRoot/WEB-INF/spring.xml");
注解方式:
class:
@ContextConfiguration(locations={"classpath:spring.xml"})
WEB-INF:
@ContextConfiguration(locations={"file:WebRoot/WEB-INF/spring.xml"})
使用注解时,Junit报错:
java.lang.NoSuchFieldError: NULL

经检查是jar包冲突,我在建项目的时候,myeclipse有自动加入junit4,而后面我又自己加入Junit4.8.1。
如果报以下错误,则是junit包版本太低,需要4.5或以上的版本
