springboot集成redis详解

springboot集成redis非常简单

1、引入maven依赖redis包

<!-- 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

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

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;br/>@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
/**

• 生成key的策略
• @returnbr/>*/
  @Bean
  public KeyGenerator keyGenerator() {
  return new KeyGenerator() {br/>@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br/>*/
  @Bean
  public CacheManager cacheManager(RedisTemplate redisTemplate) {
  RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
  return rcm;
  }
  /**
• RedisTemplate配置br/>*/
  @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

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;br/>@Service
public class RedisService {br/>@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。

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

• */br/>@Controller
  @RequestMapping("/demo/redis")
  public class RedisController {br/>@Autowired
  private RedisService redisService;
  /**

  • 设置Redis数据
  • @param key
  • @param value
  • @returnbr/>*/
    @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
  • @returnbr/>*/
    @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
  • @returnbr/>*/
    @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.
