为什么我用spring注解读不到我配置文件里面的值??

//运用注解读取配置文件

@Component
@ComponentScan
@Configuration
@PropertySource({ "classpath:/info.properties" })
public class PropertiesResolve {
private static Logger logger = Logger.getLogger(PropertiesResolve.class.getName());
//把配置文件的属性值直接注解到类的属性里面
    @Value("${mongodb.url}") //url  
    static String mongodbUrl;
    @Value("${mongodb.name}") //name  
    static String mongodbName;
    @Value("${mongodb.password}") //password  
    static String mongodbPassword;

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {  
        return new PropertySourcesPlaceholderConfigurer();  
    } 



@Scheduled(cron = "${time1}")
public static void test1(){
    logger.info("1111111111111111111111111");
    System.out.println("mongodbUrl的值:   "+mongodbUrl);
    System.out.println("mongodbName的值:   "+mongodbName);
    System.out.println("mongodbPassword的值:   "+mongodbPassword);
}
//*************************************************************************************
@Autowired  
private static Environment env; 

@Scheduled(cron = "${time2}")
public static void test2(){

    logger.info("2222222222222222222222");
    System.out.println(env.getProperty("mongodb.url"));
    System.out.println(env.getProperty("mongodb.name"));
    System.out.println(env.getProperty("mongodb.password"));
}
}

配置文件内容:

mongodbUrl

mongodb.url = 127.0.0.1

mongodbName

mongodb.name= xs@tt.cok

mongodbPassword

mongodb.password= 1245sdsh

time

time1 = 0/20 ?
time2 = 0/58 ?
test1输出:
mongodbUrl的值: null
mongodbName的值: null
mongodbPassword的值: null
test2方法直接报错,错误为:java.lang.NullPointerException,
就算是static String mongodbUrl属性去掉static也是一样的错误,求大神帮忙
