测试

public class App {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
        RedisTemplate rt = ctx.getBean(RedisTemplate.class);
        rt.opsForValue().set("Test", "Redis test!", 10, TimeUnit.SECONDS);
        String x = (String) rt.opsForValue().get("Test");
        System.out.println(x);
    }
}
