Configuration of Redis under Spring

This project uses Redis, so I learned how to configure Redis under the Spring framework.

1, the first is to add the spring configuration file in Web. Xml.

<web-app version= "3.0" xmlns= "Http://java.sun.com/xml/ns/javaee"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" > <display-name> Common design</display-name> <context-param> <param-name>webapprootkey</param-name&gt          ; <param-value>webapp.root</param-value> </context-param> <!--add a spring mybatis configuration file--&gt    ; <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpat H:applicationcontext.xml,classpath*:mybatis-config.xml</param-value> </context-param> <listener > <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-va lue>classpath:springmvc-servlet.xml</param-value> </init-param> </servlet> <servlet-mappi Ng> <servlet-name>springmvc</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping></web-app>

2. Then the Redis configuration file (redis-config.xml) file.

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"Xmlns:tx= "Http://www.springframework.org/schema/tx" xmlns:context= "Http://www.springframework.org/schema/context"xsi:schemalocation="http//Www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp//Www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp//WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOPhttp://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp//Www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.2.xsd"    default-autowire= "ByName"default-lazy-init= "true" > <bean id= "Poolconfig"class= "Redis.clients.jedis.JedisPoolConfig" > <property name= "maxidle" value= "${redis.maxidle}"/> &LT;PR Operty name= "Maxwaitmillis" value= "${redis.maxwait}"/> <property name= "Testonborrow" value= "${redis.testOnBo Rrow} "/> </bean> <!--redis Server Center--<bean id=" ConnectionFactory "class= "Org.springframework.data.redis.connection.jedis.JedisConnectionFactory" > <property name= "poolconfig" ref= "Poolconfig"/> <property name= "port" value= "${redis.port}"/> <property name= "HostName" value= " ${redis.host} "/> <property name=" password "value=" ${redis.password} "/> <property name=" Timeout "Value=" ${redis.timeout} "></property> </bean> <bean id=" Redistemplate "class= "Org.springframework.data.redis.core.RedisTemplate" > <property name= "connectionfactory" ref= " ConnectionFactory "/> <property name=" Keyserializer "> <Beanclass= "Org.springframework.data.redis.serializer.StringRedisSerializer"/> </property> <property Name = "ValueSerializer" > <Beanclass= "Org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/> </property> &LT;/BEAN&G    T <bean id= "Redisutil"class= "Com.zkxl.fep.redis.RedisUtil" > <property name= "redistemplate" ref= "Redistemplate"/> </bean>&lt ;/beans>

Referencing the Redis profile in spring's configuration file

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:aop= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"Xmlns:tx= "Http://www.springframework.org/schema/tx" xmlns:context= "Http://www.springframework.org/schema/context"xsi:schemalocation="http//Www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp//Www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.2.xsdhttp//WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOPhttp://www.springframework.org/schema/aop/spring-aop-3.2.xsdhttp//Www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.2.xsd"    default-autowire= "ByName"default-lazy-init= "true" > <context:annotation-config/> <context:component-scan base- Package= "Com.test.fep"/> <!--increased Redis properties file--<context:property-placeholder location= "classpath*: Jdbc.properties,classpath*:redis.properties "/> <ImportResource= "Datasource.xml"/> <!--importing Redis profiles--<ImportResource= "Redis-config.xml"/> </beans>

3. New redis.properties, which contains configuration information required for Redis connection

#redis setting  redis.host=127.0.0.1redis.port=6379redis.password=123456  Redis.maxidle=100redis.maxactive=300redis.maxwait=1000redis.testonborrow=  Trueredis.timeout=100000=10000

Be sure to note that there are no spaces behind each line, and I'm stuck with this problem for one or two hours = =

4, write Redisutil.java, inside put Redis's additions and deletions to change the operation.

 PackageCom.test.fep.redis;Importjava.io.Serializable; ImportJava.util.Set; ImportJava.util.concurrent.TimeUnit; Importorg.springframework.data.redis.core.RedisTemplate; Importorg.springframework.data.redis.core.ValueOperations;  Public classRedisutil {PrivateRedistemplate<serializable, object>redistemplate; /*** Bulk Delete the corresponding value * *@paramKeys*/     Public voidRemoveFinalString ... keys) {         for(String key:keys) {remove (key); }    }    /*** Bulk Delete key * *@parampattern*/     Public voidRemovepattern (FinalString pattern) {Set<Serializable> keys =Redistemplate.keys (pattern); if(Keys.size () > 0) Redistemplate.delete (keys); }    /*** Delete the corresponding value * *@paramKey*/     Public voidRemoveFinalString Key) {        if(Exists (key)) {Redistemplate.delete (key); }    }    /*** Determine if there is a corresponding value in the cache * *@paramKey *@return     */     Public BooleanExistsFinalString Key) {        returnRedistemplate.haskey (key); }    /*** Read Cache * *@paramKey *@return     */     PublicObject Get (FinalString Key) {Object result=NULL; Valueoperations<serializable, object> operations =Redistemplate.opsforvalue (); Result=Operations.get (key); returnresult; }    /*** Write Cache * *@paramKey *@paramValue *@return     */     Public BooleanSetFinalString key, Object value) {        Booleanresult =false; Try{valueoperations<serializable, object> operations =Redistemplate.opsforvalue ();            Operations.set (key, value); Result=true; } Catch(Exception e) {logger.error ("Set Cache Error", E); }        returnresult; }    /*** Write Cache * *@paramKey *@paramValue *@return     */     Public BooleanSetFinalString Key, Object value, Long expiretime) {        Booleanresult =false; Try{valueoperations<serializable, object> operations =Redistemplate.opsforvalue ();            Operations.set (key, value);            Redistemplate.expire (Key, Expiretime, timeunit.seconds); Result=true; } Catch(Exception e) {logger.error ("Set Cache Error", E); }        returnresult; }         Public LongIncrementFinalString Key,LongDelta) {         returnredistemplate.opsforvalue (). Increment (key, delta); }     Public voidSetredistemplate (redistemplate<serializable, object>redistemplate) {         This. redistemplate =redistemplate; }}

5. Call the method in the Redisutil class in the function code,

 PackageCom.test.fep.service.impl;ImportJava.math.BigDecimal;Importjava.util.Date;Importjava.util.List;Importorg.springframework.beans.factory.annotation.Autowired;ImportOrg.springframework.stereotype.Service;ImportCom.test.fep.domain.SysAppLoginToken;ImportCom.test.fep.mapper.SysAppLoginTokenMapper;ImportCom.test.fep.redis.RedisUtil;ImportCom.test.fep.service.AuthService;Importnet.sf.json.JSONObject; @Service ("Authservice") Public classAuthserviceimplImplementsauthservice{@AutowiredPrivateSysapplogintokenmapper Sysapplogintokenmapper; @AutowiredPrivateRedisutil Redisutil;//Remember to inject@Override Publicsysapplogintoken Verification (String Tokenid) {Sysapplogintoken token=NULL; if(Redisutil.exists (Tokenid)) {token= (Sysapplogintoken) redisutil.get (Tokenid);//find tokens from the cache}Else{token=Sysapplogintokenmapper.selectbyprimarykey (Tokenid);    Redisutil.set (Tokenid, token); //Write token to cache        }                return NULL; }}

All right, here's a complete use of Redis in a project.

It is also important to note that all interfaces that are stored in Redis must implement the Serializable interface
