SpringBoot注解的方式使用redis集群模式
使用SpringBoot都不喜欢写xml配置文件，下面我就分享一下使用配置类的方式将redis切换到集群模式
1、添加依赖
spring-boot-starter-parent已经将redis的依赖定义好了，我们不需要定义版本号：
2、编写集群配置属性类
package com.fcbox.sflowapp.config;
import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
/**
* Redis集群属性
* @author 002158
*/
@Getter
@Setter
@ConfigurationProperties(prefix = "redis.cluster")
public class ClusterRedisProperties {
/**
* 最大连接数
*/
private int maxTotal;
/**
* 最大空闲数
*/
private int maxIdle;
/**
* 初始化连接数
*/
private int minIdle;
/**
* 建立连接时最大等待时间，单位毫秒
*/
private long maxWait;
/**
* 客户端超时时间，单位毫秒
*/
private int timeout;
/**
* 指明是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
*/
private boolean testOnBorrow;
/**
* 在return给pool时，是否提前进行validate操作
*/
private boolean testOnReturn;
/**
* 如果为true，表示有一个idle object evitor线程对idle object进行扫描，如果validate失败，此object会被从pool中drop掉；
*/
private boolean testWhileIdle;
/**
* 配合testWhileIdle使用，表示idle object evitor两次扫描之间要sleep的毫秒数
*/
private long timeBetweenEvictionRunsMillis;
/**
* 集群信息
*/
private String nodes;
private int maxRedirects;
private String password;
}
3、编写配置类
package com.fcbox.sflowapp.config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.MapPropertySource;
import org.springframework.data.redis.connection.RedisClusterConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;
import java.util.HashMap;
import java.util.Map;
/**
* Redis集群配置类
* @author 002158
*/
@Configuration
@EnableConfigurationProperties(ClusterRedisProperties.class)
public class RedisConfig {
private static final String REDIS_CLUSTER_NODES_CONFIG_PROPERTY = "spring.redis.cluster.nodes";
private static final String REDIS_CLUSTER_MAX_REDIRECTS_CONFIG_PROPERTY = "spring.redis.cluster.max-redirects";
private static final String REDIS_CLUSTER_PROPERTIES = "redis.properties";
@Autowired
private ClusterRedisProperties clusterRedisProperties;
/**
* 配置jedis连接池
* @return
*/
@Bean
public JedisPoolConfig jedisPoolConfig(){
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxTotal(clusterRedisProperties.getMaxTotal());
jedisPoolConfig.setMaxIdle(clusterRedisProperties.getMaxIdle());
jedisPoolConfig.setMinIdle(clusterRedisProperties.getMinIdle());
jedisPoolConfig.setMaxWaitMillis(clusterRedisProperties.getMaxWait());
jedisPoolConfig.setTestOnBorrow(clusterRedisProperties.isTestOnBorrow());
jedisPoolConfig.setTestOnReturn(clusterRedisProperties.isTestOnReturn());
jedisPoolConfig.setTestWhileIdle(clusterRedisProperties.isTestWhileIdle());
jedisPoolConfig.setTimeBetweenEvictionRunsMillis(clusterRedisProperties.getTimeBetweenEvictionRunsMillis());
return jedisPoolConfig;
}
/**
* redis集群配置
* @return
*/
@Bean
public RedisClusterConfiguration redisClusterConfiguration(){
Map
clusterPropertie.put(REDIS_CLUSTER_NODES_CONFIG_PROPERTY, clusterRedisProperties.getNodes());
clusterPropertie.put(REDIS_CLUSTER_MAX_REDIRECTS_CONFIG_PROPERTY, clusterRedisProperties.getMaxRedirects());
MapPropertySource mapPropertySource = new MapPropertySource(REDIS_CLUSTER_PROPERTIES, clusterPropertie);
RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(mapPropertySource);
return redisClusterConfiguration;
}
/**
* 配置jedis连接工厂
* @param redisClusterConfiguration
* @param jedisPoolConfig
* @return
*/
@Bean
public JedisConnectionFactory jedisConnectionFactory(RedisClusterConfiguration redisClusterConfiguration, JedisPoolConfig jedisPoolConfig){
JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisClusterConfiguration,jedisPoolConfig );
jedisConnectionFactory.setTimeout(clusterRedisProperties.getTimeout());
jedisConnectionFactory.setPassword(clusterRedisProperties.getPassword());
return jedisConnectionFactory;
}
/**
* 配置RedisTemplate
* @param factory
* @return
*/
@Bean
public RedisTemplate redisTemplate(JedisConnectionFactory factory){
RedisTemplate redisTemplate = new RedisTemplate();
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
redisTemplate.setConnectionFactory(factory);
redisTemplate.setKeySerializer(stringRedisSerializer);
redisTemplate.setValueSerializer(stringRedisSerializer);
redisTemplate.setHashKeySerializer(stringRedisSerializer);
redisTemplate.setHashValueSerializer(stringRedisSerializer);
return redisTemplate;
}
}
4、在disconf上传redis.propertie配置文件
redis.cluster.max-total=16
redis.cluster.max-idle=3
redis.cluster.min-idle=1
redis.cluster.max-wait=1000
redis.cluster.timeout=1000
redis.cluster.test-on-borrow=true
redis.cluster.test-on-return=false
redis.cluster.test-while-idle=true
redis.cluster.time-between-eviction-runs-millis=160000
redis.cluster.max-redirects=3
#redis.cluster.nodes=127.0.0.1:6379
#redis.cluster.password=
# sit2
redis.cluster.nodes=10.204.58.11:8080,10.204.58.12:8080,10.204.58.13:8080,10.204.58.14:8080,10.204.58.15:8080,10.204.58.16:8080
redis.cluster.password=K6CJDjjnE9d0OxRjYNKZ
这样就完成了集群模式的切换了，下面测试一下：
编写一个Controller
@RequestMapping(value = "test")
@RestController
public class TestController {
@Autowired
private RedisTemplate redisTemplate;
@RequestMapping("/push")
public Object testRedisPush(String password){
redisTemplate.opsForValue().set("password", password);
return "OK";
}
@RequestMapping("/pop")
public Object testRedisPop(String password){
return redisTemplate.opsForValue().get("password");
}
}
