Redis installation, deployment, and integration with spring cache

Installation

Go to http://redis.io/Download the latest stable version of the source code. Unzip, go to unzip directory, execute

makemake install

After src/ that, there are several more files in the directory:

redis-serverredis-benchmarkredis-cliredis-conf

To the copy /usr/redis directory.

Deployment

redis-confto modify a file, add:

requirepass 111111

Set the connection password to 111111 . And then execute

./redis-server redis-conf

To start the Redis server.

Integration with spring cache

First pom.xml Add the Jedis and spring data redis dependencies in:

<!--Spring Data Redis ---        <dependency>            <groupId>Org.springframework.data</groupId>            <artifactid>Spring-data-redis</artifactid>            <version>${spring-redis}</version>        </Dependency>        <dependency>            <groupId>Redis.clients</groupId>            <artifactid>Jedis</artifactid>            <version>${jedis}</version>        </Dependency>

Because we're going to use Jackson to provide the class serialization feature, we need to add:

<dependency>            <groupId>org.codehaus.jackson</groupId>            <artifactId>jackson-mapper-asl</artifactId>            <version>1.9.4</version>        </dependency>

Then, add the following in the spring configuration file:

<!--redis cache configuration --     <beans:bean id= "redisconnectionfactory"class=" Org.springframework.data.redis.connection.jedis.JedisConnectionFactory " >                        <beans:property name="HostName" value="XX.XX.XX.XX" />         <beans:property name="password" value="111111" / >    </Beans:bean>    <!--serializer --    <beans:bean id= "keyserializer" class=" Org.springframework.data.redis.serializer.StringRedisSerializer " />    <beans:bean id= "ValueSerializer" class=" Org.springframework.data.redis.serializer.JacksonJsonRedisSerializer " />    <!--redis template ---    <beans:bean id= "redistemplate"class=" Org.springframework.data.redis.core.StringRedisTemplate ">                        <beans:property name= "connectionfactory" ref=" Redisconnectionfactory " />        <beans:property name="Keyserializer" ref="Keyserializer " />        <beans:property name="ValueSerializer" ref="ValueSerializer" />    </Beans:bean>    <!--cache Manager --    <beans:bean id= "CacheManager" class=" Org.springframework.data.redis.cache.RedisCacheManager ">        <beans:constructor-arg name="template" ref="Redistemplate" / >    </Beans:bean>

Once you have done this, you can use the method in the service method @Cacheable :

@Override    @Transactionaltrue)    @Cacheable"cache""#username")    publicfindMemberboolean isWired) {        MemberModel mem = memMapper.selectByUsername(username);        CheckUtils.nullCheck(mem);        return mem;    }

However, using the spring cache has the disadvantage of not setting the cache expiration time. If there is a need for this, you must use the client directly instead jedis spring cache .
