Yml配置文件加载问题

在resource目录下有一个application.yml文件，希望是通过@PropertySource注解，将配置文件数据读取到Environment中，然而调试发现数据始终读取不到，google之后，记录下解决方法

在测试用例中，指定初始化方式 @ContextConfiguration(classes = RedisConf.class, initializers = ConfigFileApplicationContextInitializer.class)

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = RedisConf.class, initializers = ConfigFileApplicationContextInitializer.class)
public class RedisTest {
    @Test
    public void testRedis() {
        String ans = JedisClient.getStr("hello");
        System.out.println(ans);
    }
}

对应的配置类

@Configuration
@PropertySource(value = "classpath:application.yml")
public class RedisConf {

    @Autowired
    private Environment environment;

    @Autowired
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<String, String> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        DefaultStrSerializer serializer = new DefaultStrSerializer();
        redisTemplate.setValueSerializer(serializer);
        redisTemplate.setHashValueSerializer(serializer);
        redisTemplate.setKeySerializer(serializer);
        redisTemplate.setHashKeySerializer(serializer);

        redisTemplate.afterPropertiesSet();

        JedisClient.register(redisTemplate);
        return redisTemplate;
    }

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        LettuceConnectionFactory fac = new LettuceConnectionFactory();
        fac.getStandaloneConfiguration().setHostName(environment.getProperty("spring.redis.host"));
        fac.getStandaloneConfiguration().setPort(Integer.parseInt(environment.getProperty("spring.redis.port")));
        fac.getStandaloneConfiguration()
                .setPassword(RedisPassword.of(environment.getProperty("spring.redis.password")));
        fac.afterPropertiesSet();
        return fac;
    }
}
