package

 com.bank.service;

@RunWith(SpringJUnit4ClassRunner.class

)
//

 ApplicationContext will be loaded from "classpath:/app-config.xml"




@ContextConfiguration("/app-config.xml")
@ActiveProfiles("dev")
public

 class

 TransferServiceTest {
    @Autowired
    private

 TransferService transferService;

    @Test
    public

 void

 testTransferService() {
        //

 test the transferService




    }
}

这个除了可以切换开发、部署环境，也可以方便地切换不同的数据库。实战中发现这个TestCase还可以被继承，其配置也会被继承，所以现在的 做法是写一个基础TestCase，配置好ContextConfiguration、ActiveProfiles，其他TestCase继承该基础 TestCase。

但是集成到web环境中时，却很久找不到如何在web.xml中切换这个环境配置，找了很久总算找到了，在web.xml中加入：

<
context-param
>


    <
param-name
>
spring.profiles.active</
param-name
>


    <
param-value
>
dev</
param-value
>


</
context-param
>

经测试已成功，特此记录分享。

<!-- 設定Spring Context的Profile -->
