使用注解

 package com.wangzhixuan.service.impl;

 import java.io.Serializable;
 import java.util.Date;

 import org.springframework.beans.factory.annotation.Autowired;
 import org.springframework.cache.annotation.Cacheable;
 import org.springframework.stereotype.Service;

 import com.wangzhixuan.mapper.UserMapper;
 import com.wangzhixuan.model.User;

 @Service
 public class TestService {
     @Autowired
     private UserMapper userMapper;

     @Cacheable(value = "hour", key = "#id")
     public User selectById(Serializable id) {
         return userMapper.selectById(id);
     }
     @Cacheable(value = "hours")
        public String date() {
            return new Date().toString();
        }
 }
