springboot中使用EnvironmentPostProcessor获取不到nacos上的配置信息？

在springboot2.6版本中使用EnvironmentPostProcessor 对properties文件中的加密数据进行解密操作，但是properties是配置在nacos配置中心的，启动服务时获取不到nacos上的数据，

public class DecryptProcessor implements EnvironmentPostProcessor {
    private Logger logger = LoggerFactory.getLogger(DecryptProcessor.class);
    /**
     * 加密的属性的前缀：DEC + 密文 
     */
    private final static String DECRYPT_PREFIX = "DEC:";
    private final static int DECRYPT_PREFIX_LENGTH = DECRYPT_PREFIX.length();

    /**
     * 替换过的resource的name
     */
    private static final String DECRYPT_RESOURCE_NAME = "decryptResource";
    @Override
    public void postProcessEnvironment(ConfigurableEnvironment environment, SpringApplication application) {
        MutablePropertySources propertySources = environment.getPropertySources();
        Map<String, Object> replacedMap = new HashMap<>();
        for (PropertySource<?> propertySource : propertySources) {
            if (propertySource instanceof OriginTrackedMapPropertySource) {
                OriginTrackedMapPropertySource source = (OriginTrackedMapPropertySource) propertySource;
                for (String name : source.getPropertyNames()) {
                    Object value = source.getProperty(name);
                    if (value instanceof String) {
                        String str = (String) value;
                        if (str.contains(DECRYPT_PREFIX)) {
                            System.out.println(str);
                           String v = str.substring(DECRYPT_PREFIX_LENGTH);
                            replacedMap.put(name, "123456");
                        }
                    }
                }
            }
        }
        if (!replacedMap.isEmpty()) {
            logger.info("{} decrypt properties  has replace !", replacedMap.size());
            propertySources.addFirst(new MapPropertySource(DECRYPT_RESOURCE_NAME, replacedMap));
        }

    }

META-INF/spring.factories中配置：
org.springframework.boot.env.EnvironmentPostProcessor=pers.vic.boot.base.tool.evn.DecryptProcessor 

我在服务本地的resource目录下的application.properties中配置了一条测试数据，test.password=DEC:sdtfsldu239debug的时候是可以走到下面这里的，但是nacos上的却不行，应该是没有获取到配置中心的数据

 if (str.contains(DECRYPT_PREFIX)) {
    System.out.println(str);
   String v = str.substring(DECRYPT_PREFIX_LENGTH);
    replacedMap.put(name, "123456");
}
