Spring Junit 读取WEB-INF下的配置文件（转）

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：

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
