Java Spring代码方式和XML配置文件方式配置Redis

1、pom.xml配置

<dependency>
   <groupId>redis.clients</groupId>
   <artifactId>jedis</artifactId>
   <version>2.9.0</version>
</dependency>
<dependency>
   <groupId>org.springframework.data</groupId>
   <artifactId>spring-data-redis</artifactId>
   <version>1.8.23.RELEASE</version>
</dependency>

2、xml配置文件实现redis的配置

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- redis连接池配置 -->
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="${redis.maxTotal}"></property>
        <property name="maxIdle" value="${redis.maxIdle}"/>
        <property name="maxWaitMillis" value="${redis.maxWait}"/>
        <property name="testOnBorrow" value="${redis.testOnBorrow}"/>
        <property name="testOnReturn" value="${redis.testOnReturn}"></property>
    </bean>

    <!-- redis连接工厂 -->
    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="poolConfig" ref="jedisPoolConfig"/>

        <property name="hostName" value="${redis.host}"/>
        <property name="port" value="${redis.port}"/>
        <property name="password" value="${redis.password}"/>
        <property name="timeout" value="${redis.timeout}"/>
    </bean>

    <!--  注册StringRedisTemplate  -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>

        <property name="keySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
        <property name="valueSerializer">
            <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>
        </property>

        <property name="hashKeySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
        <property name="hashValueSerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
    </bean>

    <bean id="redisUtil" class="com.RedisUtils">
        <property name="redisTemplate" ref="redisTemplate"/>
    </bean>

</beans>

3、java代码方式实现redis的配置

在spring的配置类中，加上如下三个类。

    /**
     * redis连接池配置
     */
    @Bean
    public JedisPoolConfig jedisPoolConfig() {
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        // 链接池中最大空闲的连接数,默认为8
        jedisPoolConfig.setMaxTotal(300);
        // 连接池中最少空闲的连接数,默认为0.
        jedisPoolConfig.setMaxIdle(200);
        // 当连接池资源耗尽时，调用者最大阻塞的时间，超时将跑出异常。单位，毫秒数;默认为-1.表示永不超时.
        jedisPoolConfig.setMaxWaitMillis(1000);
        return jedisPoolConfig;
    }

    /**
     * redis连接工厂
     */
    @Bean
    public JedisConnectionFactory connectionFactory() {
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();

        jedisConnectionFactory.setPoolConfig(this.jedisPoolConfig());
        jedisConnectionFactory.setHostName(localhost);
        jedisConnectionFactory.setPort(6379);
        jedisConnectionFactory.setPassword(123456);
        jedisConnectionFactory.setTimeout(10000);

        return jedisConnectionFactory;
    }

    /**
     * 注册StringRedisTemplate
     */
    @Bean
    public StringRedisTemplate redisTemplate() {
        StringRedisTemplate redisTemplate = new StringRedisTemplate();
        redisTemplate.setConnectionFactory(this.connectionFactory());

        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new StringRedisSerializer());
        return redisTemplate;
    }
