Redis学习（3.1）spring boot整合Redis速成

本例子中，是最简略的spring boot使用redis的方式

一，pom.xml中添加

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-redis</artifactId></dependency>

二，application.properties添加

spring.redis.database=0spring.redis.host=200.200.200.177spring.redis.password=foobaredspring.redis.pool.max-active=8spring.redis.pool.max-idle=8spring.redis.pool.max-wait=-1spring.redis.pool.min-idle=0spring.redis.port=6377spring.redis.timeout=0

三，创建CachingConfigurerSupport

@Configuration@EnableCachingpublic class RedisConfig extends CachingConfigurerSupport {}

四，使用redis

@Servicepublic class RedisService {@Cacheable(value = "usercache")public User getUser(String no,String name){LogCore.BASE.debug("invoke persistent:{},{}", no, name);return new User(no, name);}}

public class User implements Serializable {private static final long serialVersionUID = 1L;public String no;public String name;public User(String no, String name) {this.no = no;this.name = name;}}

@RestControllerpublic class RedisController {@AutowiredRedisService redisService;@RequestMapping("/redis/test")public Object test(String name, String no){String _name = Objects.toString(name, "testName");String _no = Objects.toString(no, "testNo");return redisService.getUser(_no, _name);}}

启动后测试

http://localhost:8084/redis/test?name=tianyue&no=gao

返回结果

{"no":"gao","name":"tianyue"}

tips:

a.User要继承Serializable接口

b.没有指定redis的key的生成规则，则默认的规则为parms的简单链接，如本例子中name=tianyue&no=gao的key为gaotianyue，但是这样的话name=otianyue&no=ga也是gaotianyue，要自定义key方式，请看3.2下一篇文章
