一：引入maven依賴

<!-- springboot整合redis -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <!-- 排除lettuce包，使用jedis代替-->
            <exclusions>
                <exclusion>
                    <groupId>io.lettuce</groupId>
                    <artifactId>lettuce-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>

二：添加redis配置

  redis:
    host: localhost #哨兵模式下不用配置
    port: 6379 # 哨兵模式下不用配置
    password: 123456
    database: 0
    timeout: 1000
    jedis:
      pool:
        #最大連接數(shù)
        max-active: 1024
        #最大阻塞等待時(shí)間(負(fù)數(shù)表示沒(méi)限制)
        max-wait: 20000
        #最大空閑
        max-idle: 200
        #最小空閑
        min-idle: 10
    sentinel:
      master: mymaster
      nodes: 192.168.24.127:26379,192.168.24.128:26379,192.168.24.129:26379

三：編寫redis配置類（切換注釋即可切換單機(jī)、哨兵集群模式）

@Configuration
@EnableAutoConfiguration
public class RedisConfig {

    private static Logger logger= LoggerFactory.getLogger(RedisConfig.class);

    /**  單擊版配置 **/
    @Value("${spring.redis.host}")
    private String host;
    @Value("${spring.redis.port}")
    private Integer port;

    /** 哨兵模式配置  **/
    @Value("#{'${spring.redis.sentinel.nodes}'.split(',')}")
    private List<String> nodes;
    @Value("${spring.redis.sentinel.master}")
    private String master;
    @Value("${spring.redis.password}")
    private String password;

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

    /**
     * *單機(jī)版配置
     * @param @param  jedisPoolConfig
     * @return JedisConnectionFactory
     */
    @Bean
    public JedisConnectionFactory jedisConnectionFactory(JedisPoolConfig jedisPoolConfig) {
        //不使用過(guò)時(shí)的JedisConnectionFactory直接配置屬性
        RedisStandaloneConfiguration redisStandaloneConfiguration=new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setHostName(host);
        redisStandaloneConfiguration.setPort(port);
        RedisPassword redisPassword=RedisPassword.of(password);
        redisStandaloneConfiguration.setPassword(redisPassword);
        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpcf =
                (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
        //修改我們的連接池配置
        jpcf.poolConfig(jedisPoolConfig);
        //通過(guò)構(gòu)造器來(lái)構(gòu)造jedis客戶端配置
        JedisClientConfiguration jedisClientConfiguration = jpcf.build();
        return new JedisConnectionFactory(redisStandaloneConfiguration,jedisClientConfiguration);
    }

    /**
     * 哨兵模式配置
     * @return
     */
    /*@Bean
    public RedisSentinelConfiguration sentinelConfiguration(){
        RedisSentinelConfiguration redisSentinelConfiguration = new RedisSentinelConfiguration();
        //配置matser的名稱
        redisSentinelConfiguration.master(master);
        redisSentinelConfiguration.setPassword(RedisPassword.of(password));
        //配置redis的哨兵sentinel
        Set<RedisNode> redisNodeSet = new HashSet<>();
        nodes.forEach(x->{
            redisNodeSet.add(new RedisNode(x.split(":")[0],Integer.parseInt(x.split(":")[1])));
        });
        logger.info("redisNodeSet -->"+redisNodeSet);
        redisSentinelConfiguration.setSentinels(redisNodeSet);
        return redisSentinelConfiguration;
    }*/

    /**
     * 哨兵模式配置
     * @return
     */
    /*@Bean
    public JedisConnectionFactory jedisConnectionFactory(JedisPoolConfig jedisPoolConfig, RedisSentinelConfiguration sentinelConfig) {
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(sentinelConfig,jedisPoolConfig);
        return jedisConnectionFactory;
    }*/


    /**
     * 自定義redisTemplate
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    public RedisTemplate<String,Object> redisTemplate(JedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //自定義序列化方式
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        redisTemplate.setKeySerializer(jackson2JsonRedisSerializer);
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setEnableTransactionSupport(true);// 開啟事務(wù)
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    /**
     * 注入封裝RedisTemplate
     * @return RedisUtil
     * @throws
     * @Title:redisUtil
     */
    @Bean(name = "redisUtil")
    public RedisUtil redisUtil(RedisTemplate<String, Object> redisTemplate) {
        RedisUtil redisUtil = new RedisUtil();
        redisUtil.setRedisTemplate(redisTemplate);
        return redisUtil;
    }

}

四：shiro整合redis插件相關(guān)配置（切換注釋即可切換單機(jī)、哨兵集群模式）

/**
     * 配置shiro redisManager(單機(jī)版)
     * 使用的是shiro-redis開源插件
     *
     * @return
     */
    public RedisManager redisManager() {
        RedisManager redisManager = new RedisManager();
        redisManager.setHost(host);
        redisManager.setPort(port);
        redisManager.setExpire(1800);
        redisManager.setTimeout(timeout);
        redisManager.setPassword(password);
        logger.info("配置redis連接設(shè)置" + host + ":" + port);
        return redisManager;
    }

    /**
     * 配置shiro redisSentinelManager(哨兵模式)
     * 使用的是shiro-redis開源插件
     * @return
     */
    /*public RedisSentinelManager redisSentinelManager(){
        RedisSentinelManager redisSentinelManager = new RedisSentinelManager();
        redisSentinelManager.setMasterName(master);
        redisSentinelManager.setHost(redisNodes);
        redisSentinelManager.setPassword(password);
        return redisSentinelManager;
    }*/

    /**
     * cacheManager 緩存 redis實(shí)現(xiàn)
     * 使用的是shiro-redis開源插件
     *
     * @return
     */
    @Bean
    public RedisCacheManager cacheManager() {
        RedisCacheManager redisCacheManager = new RedisCacheManager();
        redisCacheManager.setRedisManager(redisManager());
        //redisCacheManager.setRedisManager(redisSentinelManager());
        return redisCacheManager;
    }

    /**
     * RedisSessionDAO shiro sessionDao層的實(shí)現(xiàn) 通過(guò)redis
     * 使用的是shiro-redis開源插件
     */
    @Bean
    public RedisSessionDAO redisSessionDAO() {
        RedisSessionDAO redisSessionDAO = new RedisSessionDAO();
        redisSessionDAO.setRedisManager(redisManager());
        //redisSessionDAO.setRedisManager(redisSentinelManager());
        return redisSessionDAO;
    }
