springboot集成redis

整合redis到springboot

1.在pom中配置redis的相关依赖包：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-redis</artifactId>
    <version>1.3.8.RELEASE</version>
</dependency>

2.application.yml

spring:
    redis:
        host: 127.0.0.1
        port: 6379
        password: pass1234
        pool:
            max-active: 100
            max-idle: 10
            max-wait: 100000
        timeout: 0

3. 编写RedisConfig.java

@Configuration
@EnableAutoConfiguration
public class RedisConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.redis.pool")
    public JedisPoolConfig getRedisConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
        return config;
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.redis")
    public JedisConnectionFactory getConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setUsePool(true);
        JedisPoolConfig config = getRedisConfig();
        factory.setPoolConfig(config);
        return factory;
    }

    @Bean
    public RedisTemplate<?, ?> getRedisTemplate() {
        JedisConnectionFactory factory = getConnectionFactory();
        RedisTemplate<?, ?> template = new StringRedisTemplate(factory);
        return template;
    }

}

4.RedisService.java

public interface RedisService {

    /**
     * set存数据
     * @param key
     * @param value
     * @return
     */
    boolean set(String key, String value);

    /**
     * get获取数据
     * @param key
     * @return
     */
    String get(String key);

    /**
     * 设置有效天数
     * @param key
     * @param expire
     * @return
     */
    boolean expire(String key, long expire);

    /**
     * 移除数据
     * @param key
     * @return
     */
    boolean remove(String key);

}

5.RedisServiceImpl.java

@Service("redisService")
public class RedisServiceImpl implements RedisService {

    @Resource
    private RedisTemplate<String, ?> redisTemplate;

    @Override
    public boolean set(final String key, final String value) {
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
            @Override
            public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                connection.set(serializer.serialize(key), serializer.serialize(value));
                return true;
            }
        });
        return result;
    }

    @Override
    public String get(final String key) {
        String result = redisTemplate.execute(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                byte[] value = connection.get(serializer.serialize(key));
                return serializer.deserialize(value);
            }
        });
        return result;
    }

    @Override
    public boolean expire(final String key, long expire) {
        return redisTemplate.expire(key, expire, TimeUnit.SECONDS);
    }

    @Override
    public boolean remove(final String key) {
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
            @Override
            public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                connection.del(key.getBytes());
                return true;
            }
        });
        return result;
    }
}
