一、创建Spring Boot项目并添加依赖
compile('org.springframework.boot:spring-boot-starter-data-redis')
二、添加配置类
RedisConfig
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cache.CacheManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.stereotype.Component;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
@Component
@Configuration
public class RedisConfig {
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.timeout}")
private int timeout;
@Value("${spring.redis.password}")
private String password;
private StringRedisTemplate redisTemplate;
@Autowired
public RedisConfig(StringRedisTemplate redisTemplate) {
setSerializer(redisTemplate);
this.redisTemplate = redisTemplate;
}
@Bean
public JedisPoolConfig getRedisConfig() {
JedisPoolConfig config = new JedisPoolConfig();
return config;
}
@Bean
public JedisPool getJedisPool() {
JedisPoolConfig config = getRedisConfig();
JedisPool pool = new JedisPool(config, host, port, timeout, password);
return pool;
}
//缓存管理器
@Bean
public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {
RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);
//设置缓存过期时间
cacheManager.setDefaultExpiration(10000);
return cacheManager;
}
private void setSerializer(RedisTemplate template) {
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);
}
}
三、使用
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
@RestController
public class RedisController {
@Autowired
private JedisPool jedisPool;
@Autowired
private RedisTemplate redisTemplate;
/**
* 使用Jedis
*/
@GetMapping("/testRedis")
public String testRedis() {
String key = "Hello Redis";
Jedis jedis = jedisPool.getResource();
jedis.set(key, "Welcome to learn Redis!");
return jedis.get(key);
}
/**
* 使用Spring提供的RedisTemplate
*/
@GetMapping("/testRedisT")
public String testRedisTemplate() {
String key = "Hello Redis";
ValueOperations ops = redisTemplate.opsForValue();
ops.set(key, "Welcome to learn Redis integrate with Spring Boot!");
return (String) ops.get(key);
}
}
