获取@ContextConfiguration注解中的配置文件路径和配置文件中value

@ContextConfiguration Spring整合JUnit4测试时，使用注解引入多个配置文件

单个文件 
@ContextConfiguration(Locations="../applicationContext.xml")  

@ContextConfiguration(classes = SimpleConfiguration.class)


多个文件时，可用{}

@ContextConfiguration(locations = { "classpath*:/spring1.xml", "classpath*:/spring2.xml" }) 

如果我想获取配置文件的路径，可以通过ContextConfiguration注解获取到locations信息

 

        //this.getClass获取当前类，在反射中获取的与本地获取的对应的测试类是一样的
       ContextConfiguration configuration = this.getClass().getAnnotation(ContextConfiguration.class);
        String[]  locations = configuration.locations();
        //这里返回的是一个数组，可以根据下标获取对应的配置文件名
        String location = locations[0].replace("classpath:","");

根据bean获取配置文件中对应的value，完整代码如下

    private  String getRemoteAppKey(String testClassServiceName){
        ContextConfiguration configuration = this.getClass().getAnnotation(ContextConfiguration.class);
        String[]  locations = configuration.locations();
        String location = locations[0].replace("classpath:","");

        ClassPathResource resource = new ClassPathResource(location);
        DefaultListableBeanFactory factory = new DefaultListableBeanFactory();
        XmlBeanDefinitionReader reader = new XmlBeanDefinitionReader(factory);
        reader.loadBeanDefinitions(resource);

        BeanDefinitionRegistry registry = reader.getRegistry();
        BeanDefinition definition = registry.getBeanDefinition(lowerFirst(testClassServiceName));

        MutablePropertyValues mutablePropertyValues = definition.getPropertyValues();

        TypedStringValue remoteAppkey  = (TypedStringValue) mutablePropertyValues.get("remoteAppkey");

        return remoteAppkey.getValue();
    }
