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.hostName=192.168.0.120 #\u7aef\u53e3\u53f7 redis.port=6379 #\u5ba2\u6237\u7aef\u8d85\u65f6\u65f6\u95f4\u5355\u4f4d\u662f\u6beb\u79d2 \u9ed8\u8ba4\u662f2000 redis.timeout=10000 #\u6700\u5927\u7a7a\u95f2\u6570 redis.maxIdle=300 #\u8fde\u63a5\u6c60\u7684\u6700\u5927\u6570\u636e\u5e93\u8fde\u63a5\u6570\u3002\u8bbe\u4e3a0\u8868\u793a\u65e0\u9650\u5236,\u5982\u679c\u662fjedis 2.4\u4ee5\u540e\u7528redis.maxTotal #redis.maxActive=600 #\u63a7\u5236\u4e00\u4e2apool\u53ef\u5206\u914d\u591a\u5c11\u4e2ajedis\u5b9e\u4f8b,\u7528\u6765\u66ff\u6362\u4e0a\u9762\u7684redis.maxActive,\u5982\u679c\u662fjedis 2.4\u4ee5\u540e\u7528\u8be5\u5c5e\u6027 redis.maxTotal=1000 #\u6700\u5927\u5efa\u7acb\u8fde\u63a5\u7b49\u5f85\u65f6\u95f4\u3002\u5982\u679c\u8d85\u8fc7\u6b64\u65f6\u95f4\u5c06\u63a5\u5230\u5f02\u5e38\u3002\u8bbe\u4e3a-1\u8868\u793a\u65e0\u9650\u5236\u3002 redis.maxWaitMillis=1000 #\u8fde\u63a5\u7684\u6700\u5c0f\u7a7a\u95f2\u65f6\u95f4 \u9ed8\u8ba41800000\u6beb\u79d2(30\u5206\u949f) redis.minEvictableIdleTimeMillis=300000 #\u6bcf\u6b21\u91ca\u653e\u8fde\u63a5\u7684\u6700\u5927\u6570\u76ee,\u9ed8\u8ba43 redis.numTestsPerEvictionRun=1024 #\u9010\u51fa\u626b\u63cf\u7684\u65f6\u95f4\u95f4\u9694(\u6beb\u79d2) \u5982\u679c\u4e3a\u8d1f\u6570,\u5219\u4e0d\u8fd0\u884c\u9010\u51fa\u7ebf\u7a0b, \u9ed8\u8ba4-1 redis.timeBetweenEvictionRunsMillis=30000 #\u662f\u5426\u5728\u4ece\u6c60\u4e2d\u53d6\u51fa\u8fde\u63a5\u524d\u8fdb\u884c\u68c0\u9a8c,\u5982\u679c\u68c0\u9a8c\u5931\u8d25,\u5219\u4ece\u6c60\u4e2d\u53bb\u9664\u8fde\u63a5\u5e76\u5c1d\u8bd5\u53d6\u51fa\u53e6\u4e00\u4e2a redis.testOnBorrow=true #\u5728\u7a7a\u95f2\u65f6\u68c0\u67e5\u6709\u6548\u6027, \u9ed8\u8ba4false redis.testWhileIdle=true #redis\u96c6\u7fa4\u914d\u7f6e spring.redis.cluster.nodes=10.2.193.28:7000,10.2.193.28:7001,10.2.193.28:7002,10.2.193.29:7003,10.2.193.29:7004,10.2.193.29:7005 spring.redis.cluster.max-redirects=4 |
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() > 0) { for (String node : nodesList) { if (node != null) { String[] hostAndPort = node.split(":"); HostAndPort hostAndPort2 = new HostAndPort(hostAndPort[0], Integer.parseInt(hostAndPort[1])); 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, 0, -1); } @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
