大家好,又见面了,我是你们的朋友全栈君。

springboot集成redis非常简单

1、引入maven依赖redis包

代码语言:javascript复制
<!-- springboot整合 redis -->
<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-redis</artifactId>
</dependency>

2、application.yml配置文件中配置redis环境

代码语言:javascript复制
spring:
 redis:
 host: localhost
 #password: redispassword
 port: 6379
 pool:
 max-idle: 100
 min-idle: 1
 max-active: 1000
 max-wait: -1

3、书写配置文件RedisConfig

代码语言:javascript复制
package com.kinder.redis;
import java.lang.reflect.Method;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
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.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
	/**
	 * 生成key的策略
	 * 
	 * @return
	 */
	@Bean
	public KeyGenerator keyGenerator() {
		return new KeyGenerator() {
			@Override
			public Object generate(Object target, Method method, Object... params) {
				StringBuilder sb = new StringBuilder();
				sb.append(target.getClass().getName());
				sb.append(method.getName());
				for (Object obj : params) {
					sb.append(obj.toString());
				}
				return sb.toString();
			}
		};
	}
	/**
	 * 管理缓存
	 */
	@Bean
	public CacheManager cacheManager(RedisTemplate redisTemplate) {
		RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
		return rcm;
	}
	/**
	 * RedisTemplate配置
	 */
	@Bean
	public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
		StringRedisTemplate template = new StringRedisTemplate(factory);
		Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
		ObjectMapper om = new ObjectMapper();
		om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
		om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
		jackson2JsonRedisSerializer.setObjectMapper(om);
		template.setValueSerializer(jackson2JsonRedisSerializer);
		template.afterPropertiesSet();
		return template;
	}
}

4、编写redis的service的服务类

代码语言:javascript复制
package com.kinder.redis;
import java.io.Serializable;
import java.util.List;
import java.util.Set;
import java.util.concurrent.TimeUnit;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.HashOperations;
import org.springframework.data.redis.core.ListOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.SetOperations;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.data.redis.core.ZSetOperations;
import org.springframework.stereotype.Service;
@Service
public class RedisService {
@Autowired
private RedisTemplate redisTemplate;
/**
* 写入缓存
* 
* @param key
* @param value
* @return
*/
public boolean set(final String key, Object value) {
boolean result = false;
try {
ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
operations.set(key, value);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
/**
* 写入缓存设置时效时间
* 
* @param key
* @param value
* @return
*/
public boolean set(final String key, Object value, Long expireTime) {
boolean result = false;
try {
ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
operations.set(key, value);
redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
result = true;
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
/**
* 批量删除对应的value
* 
* @param keys
*/
public void remove(final String... keys) {
for (String key : keys) {
remove(key);
}
}
/**
* 批量删除key
* 
* @param pattern
*/
public void removePattern(final String pattern) {
Set<Serializable> keys = redisTemplate.keys(pattern);
if (keys.size() > 0)
redisTemplate.delete(keys);
}
/**
* 删除对应的value
* 
* @param key
*/
public void remove(final String key) {
if (exists(key)) {
redisTemplate.delete(key);
}
}
/**
* 判断缓存中是否有对应的value
* 
* @param key
* @return
*/
public boolean exists(final String key) {
return redisTemplate.hasKey(key);
}
/**
* 读取缓存
* 
* @param key
* @return
*/
public Object get(final String key) {
ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
return operations.get(key);
}
/**
* 哈希 添加
* 
* @param key
* @param hashKey
* @param value
*/
public void hmSet(String key, Object hashKey, Object value) {
HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();
hash.put(key, hashKey, value);
}
/**
* 哈希获取数据
* 
* @param key
* @param hashKey
* @return
*/
public Object hmGet(String key, Object hashKey) {
HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();
return hash.get(key, hashKey);
}
/**
* 列表添加
* 
* @param k
* @param v
*/
public void lPush(String k, Object v) {
ListOperations<String, Object> list = redisTemplate.opsForList();
list.rightPush(k, v);
}
/**
* 列表获取
* 
* @param k
* @param l
* @param l1
* @return
*/
public List<Object> lRange(String k, long l, long l1) {
ListOperations<String, Object> list = redisTemplate.opsForList();
return list.range(k, l, l1);
}
/**
* 集合添加
* 
* @param key
* @param value
*/
public void add(String key, Object value) {
SetOperations<String, Object> set = redisTemplate.opsForSet();
set.add(key, value);
}
/**
* 集合获取
* 
* @param key
* @return
*/
public Set<Object> setMembers(String key) {
SetOperations<String, Object> set = redisTemplate.opsForSet();
return set.members(key);
}
/**
* 有序集合添加
* 
* @param key
* @param value
* @param scoure
*/
public void zAdd(String key, Object value, double scoure) {
ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
zset.add(key, value, scoure);
}
/**
* 有序集合获取
* 
* @param key
* @param scoure
* @param scoure1
* @return
*/
public Set<Object> rangeByScore(String key, double scoure, double scoure1) {
ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
return zset.rangeByScore(key, scoure, scoure1);
}
}

5、操作redis。

代码语言:javascript复制
package com.kinder.demo.controller;
import java.util.HashMap;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.kinder.redis.RedisService;
import com.kinder.util.ResultUtil;
/**
* redis操作
* 
* @author Administrator
* 
*/
@Controller
@RequestMapping("/demo/redis")
public class RedisController {
@Autowired
private RedisService redisService;
/**
* 设置Redis数据
* 
* @param key
* @param value
* @return
*/
@RequestMapping("/setRedis.do")
@ResponseBody
public Object setRedis(String key, String value) {
redisService.set(key, value);
return ResultUtil.returnSuccess();
}
/**
* 根据key删除Redis数据
* 
* @param key
* @return
*/
@RequestMapping("/delRedis.do")
@ResponseBody
public Object delRedis(String key) {
redisService.remove(key);
return ResultUtil.returnSuccess();
}
/**
* 根据key获取Redis数据
* 
* @param key
* @return
*/
@RequestMapping("/getRedis.do")
@ResponseBody
public Object getRedis(String key) {
Object value = redisService.get(key);
Map<String, Object> map = new HashMap<String, Object>();
map.put("value", value);
return ResultUtil.returnSuccess(map);
}
}

The end.
