（1）首先，在springboot项目pom.xml中引入redis依赖
<dependency>
<groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>（2）将redis需要的配置写入application.properties中方便修改时不改动代码
# Redis数据库索引（默认为0）spring.redis.database=0# Redis服务器地址spring.redis.host=127.0.0.1# Redis服务器连接端口spring.redis.port=6379# Redis服务器连接密码（默认为空）spring.redis.password=# 连接池最大连接数（使用负值表示没有限制）spring.redis.pool.max-active=8# 连接池最大阻塞等待时间（使用负值表示没有限制）spring.redis.pool.max-wait=-1# 连接池中的最大空闲连接spring.redis.pool.max-idle=8# 连接池中的最小空闲连接spring.redis.pool.min-idle=0# 连接超时时间（毫秒）spring.redis.timeout=0# 设置key失效时间（秒）spring.redis.expire=600
（3）在springboot中注册Redis配置，在启动时执行该配置
RedisConfig.java(放在springboot能扫描到的包下)
package com.zxyp.redis;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;import org.springframework.data.redis.core.RedisTemplate;import org.springframework.data.redis.core.StringRedisTemplate;import redis.clients.jedis.JedisPoolConfig;@Configurationpublic class RedisConfig { @Value("${spring.redis.host}") private String hostname; @Value("${spring.redis.password}") private String password; @Value("${spring.redis.port}") private Integer port; @Value("${spring.redis.database}") private Integer database; @Bean @ConfigurationProperties(prefix = "spring.redis") public JedisPoolConfig getRedisConfig() { JedisPoolConfig config = new JedisPoolConfig(); return config; } @Bean @ConfigurationProperties(prefix = "spring.redis") public JedisConnectionFactory getConnectionFactory(){ JedisConnectionFactory factory = new JedisConnectionFactory(); JedisPoolConfig config = getRedisConfig(); factory.setPoolConfig(config); factory.setHostName(hostname); factory.setPassword(password); factory.setPort(port); factory.setDatabase(database); System.out.println("JedisConnectionFactory bean init success."); return factory; } @Bean public RedisTemplate getRedisTemplate() { RedisTemplate template = new StringRedisTemplate(getConnectionFactory()); return template; }} （4）根据需求写对应的redis缓存服务接口，我这里写了get取缓存，set存缓存，expire给缓存设置对应的失效时间，flushall清空所有缓存，delete清空对应key的缓存
RedisDao.java (service层接口)
package com.zxyp.redis;public interface RedisDao { public void set(String key,String value); public String get(String key); public void delete(String key); public void expire(String key, Long value); void flushall();} （5）实现Service层RedisDao接口
RedisDaoImpl.java
package com.zxyp.redis.impl;import javax.annotation.Resource;import org.springframework.dao.DataAccessException;import org.springframework.data.redis.connection.RedisConnection;import org.springframework.data.redis.core.RedisCallback;import org.springframework.data.redis.core.RedisTemplate;import org.springframework.data.redis.serializer.RedisSerializer;import org.springframework.stereotype.Repository;import com.zxyp.redis.RedisDao;@Repository("springdatadao")public class SpringDataRedisDaoImpl implements RedisDao { @Resource private RedisTemplate redisTemplate; @Override public void set(String key, String value) { redisTemplate.execute(new RedisCallback () { @Override public Boolean doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer serializer = redisTemplate.getStringSerializer(); connection.set(serializer.serialize(key), serializer.serialize(value)); return true; } }); } @Override public String get(String key) { try { String result = redisTemplate.execute(new RedisCallback () { @Override public String doInRedis(RedisConnection connection) throws DataAccessException { RedisSerializer serializer = redisTemplate.getStringSerializer(); byte[] value = connection.get(serializer.serialize(key)); return serializer.deserialize(value); } }); return result; } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return "destory"; } @Override public void delete(String key) { redisTemplate.execute(new RedisCallback 说明：get之所以要检测异常，是因为redis服务可能会挂掉，如果服务挂掉可以通过返回值判断，并作出处理，不会影响业务
（6）Redis服务的使用，在对应需要调用服务的Controller中注入该Service层接口，调用对应的方法即可，这里是我使用的示例，仅供参考
ContenController.java (此Controller引用了自己项目封装的pager，不能直接使用，只是作为使用redis的参考)
package com.zxyp.controller;import java.util.List;import java.util.Map;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.beans.factory.annotation.Value;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import com.alibaba.fastjson.JSON;import com.zxyp.ContentService;import com.zxyp.UserService;import com.zxyp.base.web.BaseController;import com.zxyp.base.web.ResultEntity;import com.zxyp.dao.entity.Pager;import com.zxyp.domain.Govtheme;import com.zxyp.redis.RedisDao;@RestController@SuppressWarnings("rawtypes") @RequestMapping("/shareContent")public class ContenController { @Autowired private ContentService contentService; @Autowired private UserService userService; @Resource @Qualifier("springdatadao") private RedisDao redisDao; @Value("${spring.redis.expire}") private Long expiretime; /** * 查询部门列表内容 * @return */ @RequestMapping(value = "/shareDepartPager",method= RequestMethod.POST) public ResultEntity queryDepartContentPager(@RequestBody Map map){ int pageSize = Integer.parseInt(map.get("pageSize")+""); int currentPage = Integer.parseInt(map.get("currentPage")+""); String type = map.get("type")+""; String userid = map.get("userid")+""; String fileid = (String)map.get("fileid"); String id = String.valueOf(map.get("id")); String redisKey = String.valueOf(currentPage)+String.valueOf(pageSize)+type+userid+fileid+id; Pager pager = null; String pageStr = redisDao.get(redisKey); if(!"destory".equals(pageStr)) { if(pageStr != null) { pager = JSON.parseObject(pageStr,Pager.class); } else { pager = new Pager(); pager.setPageSize(pageSize); pager.setCurrentPage(currentPage); pager = contentService.querySharePager(map, pager); redisDao.set(redisKey, JSON.toJSONString(pager)); redisDao.expire(redisKey, expiretime); } } else { pager = new Pager(); pager.setPageSize(pageSize); pager.setCurrentPage(currentPage); pager = contentService.querySharePager(map, pager); } return ResultEntity.createSuccessInstance(pager); }}
