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();
       }
}
