Spring Junit 读取WEB-INF下的配置文件

本文介绍了Spring框架中配置文件的不同放置位置及其加载方式。包括配置文件位于类路径下时如何通过ClassPathXmlApplicationContext加载,以及配置文件位于WEB-INF目录下时如何通过FileSystemXmlApplicationContext加载。此外还介绍了如何使用Spring JUnit支持进行单元测试。

假设Spring配置文件为applicationContext.xml


一、Spring配置文件在类路径下面

在Spring的java应用程序中,一般我们的Spring的配置文件都是放在放在类路径下面(也即编译后会进入到classes目录下)。

以下是我的项目,因为是用maven管理的,所以配置文件都放在“src/main/resources”目录下



这时候,在代码中可以通过

  1. ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");  
然后获取相应的bean。


如果代码想用Junit测试框架来测试,则Spring提供了对Junit支持,还可以使用注解的方式:

  1. @RunWith(SpringJUnit4ClassRunner.class)  
  2. @ContextConfiguration(locations={"classpath:applicationContext.xml"})  

只需要在相应的Test类前面加上此两个注解(第二个注解用来指明Spring的配置文件位置),就可以在Junit Test类使用中Spring提供的依赖注入功能。


二、Spring配置文件在WEB-INF下面

当然在做J2EE开发时,有些人习惯把Spring文件放在WEB-INF目录(虽然更多人习惯放在类路径下面)下面;或者有些Spring配置文件是放在类路径下面,而有些又放在

WEB-INF目录下面,如下图。


这时候,在代码中就不可以使用ClassPathXmlApplicationContext来加载配置文件了,而应使用FileSystemXmlApplicationContext。

  1. ApplicationContext applicationContext = new FileSystemXmlApplicationContext("src/main/webapp/WEB-INF/applicationContext.xml");  

然后获取相应的bean。


如果代码想用Junit测试框架来测试,则Spring提供了对Junit支持,还可以使用注解的方式:

  1. @RunWith(SpringJUnit4ClassRunner.class)  
  2. @ContextConfiguration(locations={"file:src/main/webapp/WEB-INF/applicationContext.xml"})   
只需要在相应的Test类前面加上此两个注解(第二个注解用来指明Spring的配置文件位置),就可以在Junit Test类使用中Spring提供的依赖注入功能。


下面是我的一个Spring管理下的Junit测试类:

  1. package com.sohu.group.service.external;  
  2.   
  3. import java.util.List;  
  4.   
  5. import org.junit.Test;  
  6. import org.junit.runner.RunWith;  
  7. import org.springframework.beans.factory.annotation.Autowired;  
  8. import org.springframework.test.context.ContextConfiguration;  
  9. import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  
  10.   
  11. @RunWith(SpringJUnit4ClassRunner.class)  
  12. @ContextConfiguration({"file:src/main/webapp/WEB-INF/applicationContext.xml"})  
  13. public class SuFriendServiceImplOverRMITest {  
  14.   
  15.     @Autowired  
  16.     private SuFriendService suFriendService;  
  17.       
  18.     @Test  
  19.     public void getUserFollowerListTest(){  
  20.         List<String> list = suFriendService.getUserFollowerList("liug_talk@163.com");  
  21.         System.out.println("------"+list);  
  22.     }  


@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations={"file:WebContent/WEB-INF/config/spring/*applicationContext*.xml","file:WebContent/WEB-INF/config/*.xml"})  
public class TestLoadSpring {
	
	
	@Autowired
	private SaleService saleService;
	
	@Test
	public void listSales(){
		
		List<SaleVo> listSales=saleService.list(new HashMap(), "", 1, 10, true);
		
		for(SaleVo vo:listSales){
			
			System.out.println(JSONObject.toJSON(vo));
			
		}
		
	}

}
