redis哨兵模式整合spring boot-蒲公英云

1、配置文件配置

spring:
  redis:
    password: 123456
    sentinel:
      master: mymaster #当前监控的名字
      nodes: 10.18.33.88:26379,10.18.33.88:36379,10.18.33.88:46379 #哨兵节点

2、创建配置类

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisNode;
import org.springframework.data.redis.connection.RedisPassword;
import org.springframework.data.redis.connection.RedisSentinelConfiguration;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
@Configuration
public class RedisConfigSentinel {
    @Value("${spring.redis.sentinel.master}")
    private String sentinelMaster;
    @Value("${spring.redis.sentinel.nodes}")
    private String sentinelNodes;
    @Value("${spring.redis.password}")
    private String redisPassword;
    /**
     * 实例化哨兵配置
     * @return
     */
    @Bean
    public RedisSentinelConfiguration sentinelConfiguration() {
        RedisSentinelConfiguration rsc = new RedisSentinelConfiguration();
        rsc.setMaster(sentinelMaster);
        rsc.setPassword(RedisPassword.of(redisPassword));
        String[] node = sentinelNodes.split(",");
        for (int i = 0; i < node.length; i++) {
            String[] add = node[i].split(":");
            RedisNode redisNode = new RedisNode(add[0], Integer.parseInt(add[1]));
            rsc.addSentinel(redisNode);
        }
        return rsc;
    }
    /**
     * 实例化 RedisTemplate 对象
     *
     * @return
     */
    @Bean("redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory,
                                                       RedisSentinelConfiguration sentinelConfiguration) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        // 使用Jackson2JsonRedisSerialize 替换默认序列化
        Jackson2JsonRedisSerializer 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);
        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        // 开启事物
        redisTemplate.setEnableTransactionSupport(false);
        return redisTemplate;
    }
}

3、创建redis 使用工具类

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.*;
import org.springframework.stereotype.Component;
import java.io.Serializable;
import java.util.List;
import java.util.Set;

     *
     * @param key
     * @param offset   位 8Bit=1Byte
     * @return
     */
    public boolean setBit(String key, long offset, boolean isShow) {
        boolean result = false;
        try {

            operations.setBit(key, offset, isShow);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
    /**

     */

        } catch (Exception e) {

        }
        return result;
    }
    /**

            operations.set(key, value);
            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();

    }
    /**

4、建立测试

@Controller
@RequestMapping(value = "/test1")
public class TestController {
    @Autowired
    private RedisUtils redisUtils;
    @RequestMapping(value = "/toStr")
    @ResponseBody
    public String getStr() {
        redisUtils.set("key","test");
        System.out.println(redisUtils.get("key"));
        return "str";
    }
}
