windows的redis版本下载：http://download.csdn.net/download/a295277302/9940194

源码路径：http://download.csdn.net/download/a295277302/9946554

登陆是admin/admin

添加redis依赖jar

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
<version>1.4.7.RELEASE</version>
</dependency>

指明版本号是因为本文所用的springboot版本为1.5.4

如果不指明版本号会出现unknown的问题

查找原因是因为redis到目前的最高版本为1.4.7.RELEASE

所以才会找不到版本号。

之后添加RedisConfig

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport{

@Bean
public KeyGenerator keyGenerator() {
return new KeyGenerator() {
@Override
public Object generate(Object target, Method method, Object... params) {
StringBuilder sb = new StringBuilder();
sb.append(target.getClass().getName());
sb.append(method.getName());
for (Object obj : params) {
sb.append(obj.toString());
}
return sb.toString();
}
};
}

@SuppressWarnings("rawtypes")
@Bean
public CacheManager cacheManager(RedisTemplate redisTemplate) {
RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
//设置缓存过期时间
//rcm.setDefaultExpiration(60);//秒
return rcm;
}

@Bean
public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
StringRedisTemplate template = new StringRedisTemplate(factory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
template.setValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}

}

到目前为止 Redis缓存已经添加成功了。

测试：

@Autowired
private StringRedisTemplate stringRedisTemplate;
@Autowired
private RedisTemplate redisTemplate;

字符串缓存

stringRedisTemplate.opsForValue().set("aaa", "111");

对象缓存

ser user=new User("aa@126.com", "aa", "aa123456", "aa","123");
ValueOperations<String, User> operations=redisTemplate.opsForValue();
operations.set("com.neox", user);
operations.set("com.neo.f", user,1,TimeUnit.SECONDS);
Thread.sleep(1000);
//redisTemplate.delete("com.neo.f");
boolean exists=redisTemplate.hasKey("com.neo.f");
if(exists){
System.out.println("exists is true");
}else{
System.out.println("exists is false");
}

注解缓存

@Cacheable(value="user-key")
public UserResponse getUserInfo(@PathVariable String id){
UserResponse user = userService.findById(id);
return user;
}

目前本地缓存为：
