SringBoot 演示 redis 一主多从+哨兵模式 高可用模拟

redis 主从复制模式

redis 一主多从 + sentinel哨兵模式

我们先创建个简单的springboot web项目

如下图所示：

创建完成后，我们导入redis jar包

<!-- 导入redis依赖包 --><dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-data-redis</artifactId></dependency>

application.properties

server.port=8080 spring.redis.database=0spring.redis.timeout=10000spring.redis.password=redis密码 spring.redis.pool.max-idle=8spring.redis.pool.min-idle=0spring.redis.pool.max-active=8spring.redis.pool.max-wait=-1 # 哨兵的主master名字spring.redis.sentinel.master=mymaster# 哨兵的密码spring.redis.sentinel.password=RedisSentinel密码# 三个哨兵的链接方式spring.redis.sentinel.nodes=192.168.0.124:26379,192.168.0.124:26380,192.168.0.124:26381

HelloController.java

import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.StringRedisTemplate;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController; /** * redis sentinel 高可用测试 * * @author sun * @date 2021/10/29 17:16 */@RestController@RequestMapping("hello")@Slf4jpublic class HelloController {     @Autowired    private StringRedisTemplate stringRedisTemplate;     @RequestMapping("index")    public Object index(@RequestParam(defaultValue = "redisKey") String key, @RequestParam(defaultValue = "redisValue") String value) {        log.info("请求到达");        stringRedisTemplate.opsForValue().set(key, value);         Object redisValue = stringRedisTemplate.opsForValue().get(key);        log.info("key：{} - value：{}", key, redisValue);         return value;    } }

测试类

@SpringBootTest@Slf4jclass RedisDemoApplicationTests {     @Autowired    private StringRedisTemplate stringRedisTemplate;     @Test    void testSetRedis() {        String key = "rediskey";        stringRedisTemplate.opsForValue().set(key, "Hello World!");         String value = stringRedisTemplate.opsForValue().get(key);        log.info("key：{} - value：{}", key, value);    }     @Test    void contextLoads() {    } }
