Springboot Integrated Redis Detailed

Welcome to join Java Kochi Group Communication

Springboot Integrated Redis is simple

1. Introducing MAVEN-dependent Redis packages

<!--  Springboot integrated Redis--><dependency>    <groupid>org.springframework.boot</groupid >    <artifactId>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 to generate key * *@return */@Beanpublic keygenerator Keygenerator () {return new Keygenerator () {@Overridepublic object Generate (Object Target, 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 ();}};} /** * Manage Cache */@Beanpublic CacheManager CacheManager (redistemplate redistemplate) {Rediscachemanager RCM = new Rediscachema Nager (redistemplate); return RCM;} /** * redistemplate configuration */@Beanpublic redistemplate<string, string> redistemplate (Redisconnectionfactory Factory) {stringredistemplate template = new Stringredistemplate (factory); Jackson2jsonredisserializer Jackson2jsonredisserializer = new Jackson2jsonredisserializer (Object.class); O Bjectmapper om = new Objectmapper (); Om.setvisibility (Propertyaccessor.all, JsonAutoDetect.Visibility.ANY); o M.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<serializabl E, object> operations = Redistemplate.opsforvalue (); Operations.set (key, value); result = true;} catch (Exception e) {e.printstacktrace ();} return result;} /** * Write Cache settingsAging Time * * @param key * @param value * @return */public Boolean set (Final String key, Object value, Long expiretime) {Boole An result = False;try {valueoperations<serializable, object> operations = Redistemplate.opsforvalue (); O Perations.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 = RedisT Emplate.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 in the cache * * @param key * @return */public Boolean exists (final String key) {return Redistemplate.haskey (ke y);} /** * 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);} /** * Hash Fetch data * * @param key * @param hashkey * @return */public object Hmget (String key, Object HashKey) {hashoperations& Lt String, Object, object> hash = Redistemplate.opsforhash (); return Hash.get (Key, HashKey);} /** * List Add * * @param k * @param v */public void Lpush (String K, Object v) {listoperations<string, object> list = R Edistemplate.opsforlist (); List.rightpush (k, v);} /** * List Get * * @param k * @param l * @param L1 * @return */public list<object> lrange (String K, long L, long L1) {L istoperations<string, object> list = Redistemplate.opsforlist (); return List.range (K, L, L1);} /** * Collection Add * * @param keY * @param value */public void Add (String key, Object value) {setoperations<string, object> set = REDISTEMPLATE.OPSF Orset (); Set.add (key, value);} /** * Collection Gets * * @param key * @return */public set<object> setmembers (String key) {setoperations<string, Object&gt ; 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) {Z setoperations<string, object> zset = Redistemplate.opsforzset (); Zset.add (key, value, scoure);} /** * Ordered Collection gets * * @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;/** * Redis Data set * * @param key * @param value * @retur n */@RequestMapping ("/setredis.do") @ResponseBodypublic Object Setredis (string key, String value) {Redisservice.set ( Key, value); return resultutil.returnsuccess ();}  /** * Delete Redis data according to key * * @param key * @return */@RequestMapping ("/delredis.do") @ResponseBodypublic Object Delredis (String Key) {Redisservice.remove (key); return resultutil.returnsuccess ();} /** * Get Redis data based on key * * @param key * @return */@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.
