Springboot Integrated Redis is simple

1. Introducing MAVEN-dependent Redis packages

<!--springboot integrated Redis--><dependency> <groupId>org.springframework.boot</groupId> <art Ifactid>spring-boot-starter-redis</artifactid></dependency>

2. Configuring the Redis environment in the APPLICATION.YML configuration file

Spring:redis:host:localhost #password: Redispassword port:6379 pool:max-idle:100 min-idle:1 max-active:1000 max-wait:-1

3. Writing configuration file 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; @Configuration @enablecachingpublic class redisconfig extends cachingconfigurersupport {/** *  strategy for generating key  *  *  @return  */@Beanpublic  keygenerator keygenerator ()  {return  New keygenerator ()  {@Overridepublic  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 ();}};} /** *  managing Cache  */@Beanpublic  cachemanager cachemanager (redistemplate redistemplate)  {rediscachemanager rcm = new rediscachemanager (redistemplate); RETURN&NBSP;RCM;} /** * redistemplate Configuration  */@Beanpublic  RedisTemplate<String, String>  Redistemplate (redisconnectionfactory factory)  {stringredistemplate&nbsP;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. Service class to write Redis services

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;@ servicepublic class redisservice {@Autowiredprivate  redistemplate redistemplate;/**  *  Write Cache  *  *  @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;} /** *  Write Cache Settings aging time  *  *  @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;} /** *  Bulk Delete the corresponding value *  *  @param  keys */public void remove ( Final string... keys)  {for  (String key : keys)  {remove (key);}} /** *  Bulk Delete key *  *  @param  pattern */public void  Removepattern (Final string pattern)  {Set<Serializable> keys =  Redistemplate.keys (pattern);if  (keys.size ()  > 0) redistemplate.delete (keys); /** *  Delete the corresponding value *  *  @param  key */public void remove (final  string key)  {if  (exists (key))  {redistemplate.delete (key);}} /** *  determine if there is a corresponding value *  *  @param  key *  @return in the cache  */public  boolean exists (Final string key)  {return redistemplate.haskey (key);} /** *  Read Cache  *  *  @param  key *  @return  */public object  get (Final string key)  {valueoperations<serializable, object> operations  = redistemplate.opsForvalue (); Return operations.get (key);} /** *  Hash   Add  *  *  @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);} /** *  hashing Get Data  *  *  @param  key *  @param  hashkey * @ Return */public object hmget (String key, object hashkey)  {HashOperations <string, object, object> hash = redistemplate.opsforhash (); return hash.get (Key, hashkey);} /** *  list Add  *  *  @param  k *  @param  v */public void  lpush (STRING&NBSP;K,&NBSP;OBJECT&NBSP;V)  {ListOperations<String, Object> list  = Redistemplate.opsforlist (); List.rightpush (K,&NBSP;V);} /** *  list Get  *  *  @param  k *  @param  l *  @param   l1 *  @return  */public list<object> lrange (String k, long l, &NBSP;LONG&NBSP;L1)  {ListOperations<String, Object> list =  Redistemplate.opsforlist (); Return list.range (K,&NBSP;L,&NBSP;L1);} /** *  Collection Add  *  *  @param  key *  @param  value */public  void add (String key, object value)  {SetOperations<String, Object>  set = redistemplate.opsforset (); Set.add (Key, value);} /** *  Collection Get  *  *  @param  key *  @return  */public Set< Object> setmembers (String key)  {setoperations<string, object> set =  redistemplate.opsforset (); Return set.members (key);} /** *  ordered collection Add  *  *  @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);} /** *  ordered collection acquisition  *  *  @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. Operation of 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 Operation  *  *  @author  administrator *   */@Controller @requestmapping ("/demo/redis") public class rediscontroller {@ autowiredprivate redisservice redisservice;/** *  setting up Redis data  *  *  @param  key *  @param  value *  @return  */@RequestMapping ("/setredis.do") @ Responsebodypublic object setredis (String key, string value)  {redisService.set ( Key, value); return resultutil.returnsuccess ();} /** *&nTo delete redis data  *  *  @param  key *  @return  */@RequestMapping ("/ Delredis.do ") @ResponseBodypublic  object delredis (String key)  {redisservice.remove (key); Return resultutil.returnsuccess ();} /** *  redis data  *  *  @param  key *  @return based on key  */@ Requestmapping ("/getredis.do") @ResponseBodypublic  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.
