1.添加redis依赖
<dependency>
<group Id>org.springframework.boot</group Id>
<actifact Id>spring-boot-starter-redis<actifact Id>
<version>x.x.x.RELEASE</version>
</dependency>
2.添加缓存注释
@SpringBoot Application
@EnableCaching //注解开启缓存
public class application {
public static void main(String[] args) {
SpringApplication.run(Application.class,args);
}
}
3.业务逻辑层方法添加@Cacheable注解来支持缓存
@Cacheable(value = "DemoDaoCahe", key = "'demoDao.getAllDemoDaos'") //key需要双引号+单引号
public List<DemoDao> getAllDemoDao() {
return this.demoDaoMapper.getAllDemoDao();
}
4.实体实现序列化
public class DemoDao implements Serializable {
private static fianl long serialVersionUID = 1L;
...
}
5.指定缓存主机的地址
在application.properties中添加redis配置
spring.redis.host=192.168.1.11
spring.redis.port=6666
6.启动测试
localhost:8080/demoDao.html
注意：刷新一次，数据就不用查询数据库，直接使用缓存数据，除非数据库数据变化
扩展
@CacheEvit(value="DemoDaoCahe", key="'demoDao.getAllDemoDaos'") //对于增删改，需要清除缓存数据
public void deleteDemo(Inteer id)
{
this.demoDaoMapper.delete(id);
}
