这篇文章记录使用spring-boot-starter-redis访问Redis。Redis相关的的配置文件放在Resources目录下的application.yml文件中,以下所示:html
spring: profiles: dev,default,test redis: database: 1 host: 192.168.107.253 #redis test server port: 6379
首先在pom.xml中添加依赖:java
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-redis</artifactId> <version>1.3.2.RELEASE</version> </dependency>
Spring boot默认可以使用 @Autowired 注入RedisTemplate<String, String>,可是个人需求是使用HMSET来操做Redis,访问Redis的模板类型为:RedisTemplate<String, Map<String, String>>,所以使用一个配置类进行配置。redis
默认状况下,Spring boot就会为Redis注入默认值,以下图所示:spring
因为实际部署的Redis的主机、端口、数据库ID在application.yml配置文件中,所以使用 @Value 注入相应的值,shell
@Value("${spring.redis.host}") private String host; @Value("${spring.redis.port}") private int port; @Value("${spring.redis.database}") private int databaseId;
而后在Jedis链接工厂时,主机、端口、数据库ID set进去便可。数据库
@Bean public JedisConnectionFactory jedisConnectionFactory() { JedisConnectionFactory factory = new JedisConnectionFactory(); factory.setUsePool(true); JedisPoolConfig config = getRedisConfig(); factory.setPoolConfig(config); factory.setHostName(host); factory.setPort(port); factory.setDatabase(databaseId); logger.info("host:{}, port:{}, database:{}", factory.getHostName(),factory.getPort(), factory.getDatabase()); return factory; }
RedisTemplate建立须要传入JedisConnectionFactory,而后设置对象的序列化格式,若是未正确设置序列化格式,可能会致使写入的数据乱码app
配置类使用 @Configuration 标识,整个类完整代码以下:spring-boot
import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.StringRedisSerializer; import redis.clients.jedis.JedisPoolConfig; import java.util.Map; /** * Created by Administrator on 2018/4/9. */ @Configuration public class LoginMacRedisConfig { private static final Logger logger = LoggerFactory.getLogger(LoginMacRedisConfig.class); @Value("${spring.redis.host}") private String host; @Value("${spring.redis.port}") private int port; @Value("${spring.redis.database}") private int databaseId; @Bean @ConfigurationProperties(prefix = "spring.redis") public JedisPoolConfig getRedisConfig() { JedisPoolConfig config = new JedisPoolConfig(); return config; } @Bean public JedisConnectionFactory jedisConnectionFactory() { JedisConnectionFactory factory = new JedisConnectionFactory(); factory.setUsePool(true); JedisPoolConfig config = getRedisConfig(); factory.setPoolConfig(config); factory.setHostName(host); factory.setPort(port); factory.setDatabase(databaseId); logger.info("host:{}, port:{}, database:{}", factory.getHostName(),factory.getPort(), factory.getDatabase()); return factory; } @Bean public RedisTemplate<String, Map<String, String>> redisTemplate() { final RedisTemplate<String, Map<String, String>> template = new RedisTemplate<>(); template.setConnectionFactory(jedisConnectionFactory()); StringRedisSerializer stringRedisSerializer = new StringRedisSerializer(); template.setKeySerializer(stringRedisSerializer); template.setHashKeySerializer(stringRedisSerializer); template.setHashValueSerializer(stringRedisSerializer); return template; } }
这样,咱们就能够在其余类( @Service )中使用 @Autowired 注入RedisTemplate<String, Map<String, String>>了。这篇文章讨论了如何注入各类泛型的RedisTemplate。ui
@Autowired private RedisTemplate<String, Map<String, String>> hmsetTemplate;
有个时候,咱们须要在一个Spring Boot Application中使用多个RedisTemplate,可参考:[How to create a second RedisTemplate instance in a Spring Boot applicationspa
HMSET key field value [field value ...]
HMSET接受一个key,而后能够存储多个 field value。
Map<String, String> results = new HashMap<>(); results.put("mac_addr", mac); results.put("cli_verstr", cli_verstr); hmsetTemplate.opsForHash().putAll(uid, results);
具体完整代码之后再补充。
写入Redis成功后,链接redis查看最终结果:
redis-cli -h 192.168.107.253 -p 6379 redis 192.168.107.253:6379[1]> KEYS * 1) "1097672" 2) "1210073" 3) "162284" redis 192.168.107.253:6379[1]> HGET 1097672 mac_addr "7893f695112c465" redis 192.168.107.253:6379[1]> HGET 1097672623 cli_verstr "2.8"
