七、springboot（四）配置redis

1、添加依赖

　　

<dependency>

       <groupId>org.springframework.boot</groupId>

       <artifactId>spring-boot-starter-data-redis</artifactId>

   </dependency>

<dependency>

　　<groupId>redis.clients</groupId>

　　<artifactId>jedis</artifactId>

</dependency>

　　

2、添加配置文件

redis.port=

#\u5ba2\u6237\u7aef\u8d85\u65f6\u65f6\u95f4\u5355\u4f4d\u662f\u6beb\u79d2 \u9ed8\u8ba4\u662f2000

#\u6bcf\u6b21\u91ca\u653e\u8fde\u63a5\u7684\u6700\u5927\u6570\u76ee,\u9ed8\u8ba43

spring.redis.cluster.max-redirects=

3、读取配置文件

@Configuration

@PropertySource("classpath:config/redis.properties")

public class RedisConfig {

@Value("${redis.hostName}")

private String hostName;

@Value("${redis.port}")

private Integer port;

@Value("${redis.maxIdle}")

    private Integer maxIdle;

    @Value("${redis.maxTotal}")

    private Integer maxTotal;

    @Value("${redis.maxWaitMillis}")

    private Integer maxWaitMillis;

    @Value("${redis.minEvictableIdleTimeMillis}")

    private Integer minEvictableIdleTimeMillis;

    @Value("${redis.numTestsPerEvictionRun}")

    private Integer numTestsPerEvictionRun;

    @Value("${redis.timeBetweenEvictionRunsMillis}")

    private long timeBetweenEvictionRunsMillis;

    @Value("${redis.testOnBorrow}")

    private boolean testOnBorrow;

    @Value("${redis.testWhileIdle}")

    private boolean testWhileIdle;

    @Value("${spring.redis.cluster.nodes}")

    private String clusterNodes; 

    @Value("${spring.redis.cluster.max-redirects}")

    private Integer mmaxRedirectsac;

    @Bean("redisPool")

　 public JedisPool getJedisPool() {

          JedisPool jedisPool = new JedisPool(hostName, port);

          return jedisPool;

    }

    @Bean("redisCluster")

    public JedisCluster getJedisCluster() {

           List<String> nodesList = Arrays.asList(clusterNodes.split(","));

           HashSet<HostAndPort> nodesSet = new HashSet<>();

           if (nodesList != null && nodesList.size() > ) {

　　　　　　for (String node : nodesList) {

　　　　　　　　if (node != null) {

　　　　　　　　　　　String[] hostAndPort = node.split(":");

　　　　　　　　　　　HostAndPort hostAndPort2 = new HostAndPort(hostAndPort[], Integer.parseInt(hostAndPort[]));

　　　　　　　　　　　nodesSet.add(hostAndPort2);

　　　　　　　　}

　　　　　　}

　　　　}

　　　　return new JedisCluster(nodesSet);

　　}

}

4、获取redis对象　

@Service("redisService")

public class RedisServiceImpl implements IRedisService{

    private JedisCommands redis;

    @Autowired

    private JedisPool jedisPool;

    @Autowired

    private JedisCluster jedisCluster;

    @Override

    public void afterPropertiesSet() throws Exception {

        if("test".equals("test")){

            this.redis = jedisPool.getResource();

        }else{

            this.redis = jedisCluster;

        }

    }

    public JedisCommands getRedis(){

        return this.redis;

    }

    public String getValue(String key){

        return this.redis.get(key);

    }

    public String setValue(String key, String value){

        return this.redis.set(key, value);

    }

    public Long incr(String key){

        return redis.incr(key);

    }

    public String setValue(String key, String value, int seconds){

        return this.redis.setex(key, seconds, value);

    }

    public Map<String, String> hgetAll(String key){

        return redis.hgetAll(key);

    }

    public String hmset(String key, Map<String, String> map){

        return redis.hmset(key, map);

    }

    public Long expire(String key, int seconds){

        return redis.expire(key, seconds);

    }

    public void del(String key) {

    redis.del(key);

    }

　　@Override

     public List<String> lrange(String key) {

        return redis.lrange(key, , -);

     }

    @Override

    public Long lpush(String key, String... string) {

        return redis.lpush(key, string);

    }

}

public interface IRedisService extends InitializingBean{

 public String getValue(String key);

 public String setValue(String key, String value);

 public Long incr(String key);

 public Long expire(String key, int seconds);

 public Map<String, String> hgetAll(String key);

 public String hmset(String key, Map<String, String> map);

 public void del(String key);

 public String setValue(String key, String value, int seconds);

 public List<String> lrange(String key);

 public Long lpush(String key, String... string);

} 

5、测试接口

@RestController

@RequestMapping("/redis")

public class RedisController {

@Autowired

private IRedisService redisService;

@RequestMapping("/set")

public String set(String key,String value) {

　　redisService.setValue(key, value);

　　return "success";

}

@RequestMapping("/get")

public String get(String key) {

　　String value = redisService.getValue(key);

　　return value;

}

}

6、启动运行
