首先引入依赖pom

         
     
      org.springframework.boot
          
     
      spring-boot-starter-data-redis
          
     
      2.0.0.RELEASE
      
    

编写redis工具类

package cn.itchao.base;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.redis.core.StringRedisTemplate;import org.springframework.stereotype.Component;import java.util.Set;import java.util.concurrent.TimeUnit;/** * @author: jinchao * @date: 18/8/9 23:32 * @description: redis操作工具类 */@Componentpublic class BaseRedisService {	@Autowired	private StringRedisTemplate stringRedisTemplate;	public void set(String key, Object object, Long time) {		// 让该方法能够支持多种数据类型存放		if (object instanceof String) {			setString(key, object);		}		// 如果存放时Set类型		if (object instanceof Set) {			setSet(key, object);		}		// 设置有效期		if (time != null) {			stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);		}	}	public void setString(String key, Object object) {		if(object instanceof String){			String value = (String) object;			// 存放string类型			stringRedisTemplate.opsForValue().set(key, value);		}	}	public void setSet(String key, Object object) {		Set
    
      valueSet = (Set
     
      ) object;		for (String string : valueSet) {			stringRedisTemplate.opsForSet().add(key, string);		}	}	public String getString(String key) {		return stringRedisTemplate.opsForValue().get(key);	}	public void deleteKey(String key){		stringRedisTemplate.delete(key);	}}
     
    

配置集群链接信息，在application.yml文件中配置

spring:  application:    name: member-server  redis:    database: 0#单机版#    host: 127.0.0.1#    port: 6379#    password: 123456#      pool:#        max-idle: 100#        min-idle: 1#        max-active: 1000#        max-wait: -1#集群版    jedis:      pool:        max-active: 8        max-wait: -1        max-idle: 8        min-idle: 0    timeout: 10000    cluster:      nodes:        - 192.168.100.131:6001        - 192.168.100.131:6002        - 192.168.100.131:6003        - 192.168.100.131:6004        - 192.168.100.131:6005        - 192.168.100.131:6006

接下来就是如何使用redis了，这个很简单调用工具类即可

如下代码片段：

@RestControllerpublic class MemberServiceImpl extends BaseApiService implements MemberService {    @Autowired    private BaseRedisService baseRedisService;    @Autowired    private MemberMapper memberMapper;    @Override    public void testRedisSet(String key, String value) {        baseRedisService.setString(key,value);    }}
