值得注意的是使用el表达式的时候一定要先注册类PropertySourcesPlaceholderConfigurer:可以用@Bean注册或者用XML的<bean>标签

这里贴上源码:

package task;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Lazy;import org.springframework.context.annotation.PropertySource;import org.springframework.context.support.PropertySourcesPlaceholderConfigurer;import org.springframework.core.env.Environment;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Component;/** * Create by szw on 2017/11/23 10:05 */@Component@Lazy(false)@PropertySource(value = "classpath:task.properties")public class SpringTask {    @Autowired    private Environment environment;    @Value(value = "${demo.url}")    private String name;    @Scheduled(cron = "${corn}")    public void task() {        String corn = environment.getProperty("demo.url");        System.out.println("我的名字" + name);        System.out.println("我执行了:" + corn);        System.out.println("执行");    }    @Bean    public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {        return new PropertySourcesPlaceholderConfigurer();    }}
