} 将使用spring注释进行Redis配置。 package com.gkatzioura.spring.config;import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;Configuration
EnableCaching
public class RedisConfig extends CachingConfigurerSupport {Beanpublic JedisConnectionFactory redisConnectionFactory() {JedisConnectionFactory jedisConnectionFactory new JedisConnectionFactory();jedisConnectionFactory.setUsePool(true);return jedisConnectionFactory;}Beanpublic RedisSerializer redisStringSerializer() {StringRedisSerializer stringRedisSerializer new StringRedisSerializer();return stringRedisSerializer;}Bean(nameredisTemplate)public RedisTemplateString, String redisTemplate(RedisConnectionFactory cf,RedisSerializer redisSerializer) {RedisTemplateString, String redisTemplate new RedisTemplateString, String();redisTemplate.setConnectionFactory(cf);redisTemplate.setDefaultSerializer(redisSerializer);return redisTemplate;}Beanpublic CacheManager cacheManager() {return new RedisCacheManager(redisTemplate(redisConnectionFactory(),redisStringSerializer()));}} 下一步是创建我们的缓存界面 package com.gkatzioura.spring.cache;import java.util.Date;
import java.util.List;public interface CacheService {public void addMessage(String user,String message);public ListString listMessages(String user);} 用户将添加消息他将能够检索它们。 但是在我们的实施中与用户相关的消息将保留一分钟的时间。 我们使用Redis的CacheService实现如下。 package com.gkatzioura.spring.cache.impl;import com.gkatzioura.spring.cache.CacheService;
import org.springframework.data.redis.core.ListOperations;
import org.springframework.data.redis.core.RedisOperations;
import org.springframework.data.redis.core.SetOperations;
import org.springframework.stereotype.Service;import javax.annotation.Resource;
import java.time.ZonedDateTime;
import java.time.temporal.ChronoUnit;
import java.util.Date;
import java.util.List;Service(cacheService)
public class RedisService implements CacheService {Resource(name redisTemplate)private ListOperationsString, String messageList;Resource(name redisTemplate)private RedisOperationsString,String latestMessageExpiration;Overridepublic void addMessage(String user,String message) {messageList.leftPush(user,message);ZonedDateTime zonedDateTime ZonedDateTime.now();Date date Date.from(zonedDateTime.plus(1, ChronoUnit.MINUTES).toInstant());latestMessageExpiration.expireAt(user,date);}Overridepublic ListString listMessages(String user) {return messageList.range(user,0,-1);}} 我们的缓存机制将保留每个用户发送的消息列表。 为此我们将使用用户作为键来设置ListOperations接口。 RedisOperations界面使我们能够指定密钥的生存时间。 在我们的情况下它用作用户密钥。 接下来我们创建一个注入了缓存服务的控制器。 package com.gkatzioura.spring.controller;import com.gkatzioura.spring.cache.CacheService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;import java.util.List;RestController
public class MessageController {Autowiredprivate CacheService cacheService;RequestMapping(value /message,method RequestMethod.GET)ResponseBodypublic ListString greeting(String user) {ListString messages cacheService.listMessages(user);return messages;}RequestMapping(value /message,method RequestMethod.POST)ResponseBodypublic String saveGreeting(String user,String message) {cacheService.addMessage(user,message);return OK;}} 最后但并非最不重要的是我们的Application类 package com.gkatzioura.spring;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;SpringBootApplication
public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}} 为了运行只是问题 gradle bootRun翻译自: https://www.javacodegeeks.com/2015/08/integrate-redis-to-your-spring-project.htmlredis集成spring
