ssm+redis部署

 1.导入jar或对应pom(亲测可行)

下载地址:https://mvnrepository.com/

2.编写redis-config.properties

redis.host=127.0.0.1
redis.port=6379
redis.pass=
redis.database=0
redis.maxIdle=300
redis.maxWaitMillis=3000
redis.testOnBorrow=true
redis.maxTotal=6000
redis.blockWhenExhausted=true

3.编写applicationContext-redis.xml文件

<?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:p="http://www.springframework.org/schema/p"

       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:task="http://www.springframework.org/schema/task"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

           http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"
       default-autowire="byName" default-lazy-init="false">

    <context:property-placeholder location="classpath*:*.properties"/>
    <!-- redis 相关配置 -->
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <!-- 最大空闲数 -->
        <property name="maxIdle" value="${redis.maxIdle}" />
        <!-- 最大空连接数 -->
        <property name="maxTotal" value="${redis.maxTotal}" />
        <!-- 最大等待时间 -->
        <property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
        <!-- 连接超时时是否阻塞，false时报异常,ture阻塞直到超时, 默认true -->
        <property name="blockWhenExhausted" value="${redis.blockWhenExhausted}" />
        <!-- 返回连接时，检测连接是否成功 -->
        <property name="testOnBorrow" value="${redis.testOnBorrow}" />
    </bean>
    <bean id="JedisConnectionFactory"
          class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
          p:host-name="${redis.host}" p:port="${redis.port}" p:password="${redis.pass}"
          p:pool-config-ref="poolConfig"/>

    <!-- spring提供的模板对象 通过模板对象操作redis-->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="JedisConnectionFactory"/>
        <!--针对各种数据选择序列化方式,不序列化会导致查询和设置key异常-->
        <property name="keySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        </property>
        <property name="valueSerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        </property>
        <property name="hashKeySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
        </property>
    </bean>

</beans>

4. 测试

/**
 * @author laijiangfeng
 * @date 2022/8/18 17:04
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations ="classpath*:applicationContext-redis.xml")
public class JunitTest {

    @Resource
    private RedisTemplate redisTemplate;

    @Test
    public void test(){
        redisTemplate.opsForValue().set("jf","22");
        Object o = redisTemplate.opsForValue().get("jf");
        System.out.println(o);
        redisTemplate.opsForValue().set("ljf",123);
    }
}

5.序列化配置问题

 <!-- spring提供的模板对象 通过模板对象操作redis-->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="JedisConnectionFactory"/>
        <!--1.针对各种数据选择序列化方式,不序列化会导致查询和设置key异常,优点:占用内存小，效率高|缺点:只能存string型,需要转化比较麻烦-->
<!--        <property name="keySerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />-->
<!--        </property>-->
<!--        <property name="valueSerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />-->
<!--        </property>-->
<!--        <property name="hashKeySerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />-->
<!--        </property>-->

        <!-- 2.如果不配置Serializer，那么存储的时候只能使用String，如果用对象类型存储，那么会提示错误 can't cast to String！！！,优点:存储快，可以不用考虑类型|缺点:服务端查询的值是乱码,不利于调试,占用内存大-->
<!--        <property name="keySerializer">-->
<!--            &lt;!&ndash;对key的默认序列化器。默认值是StringSerializer&ndash;&gt;-->
<!--            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>-->
<!--        </property>-->
<!--        &lt;!&ndash;是对value的默认序列化器，默认值是取自DefaultSerializer的JdkSerializationRedisSerializer。&ndash;&gt;-->
<!--        <property name="valueSerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>-->
<!--        </property>-->
<!--        &lt;!&ndash;存储Map时key需要的序列化配置&ndash;&gt;-->
<!--        <property name="hashKeySerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>-->
<!--        </property>-->
<!--        &lt;!&ndash;存储Map时value需要的序列化配置&ndash;&gt;-->
<!--        <property name="hashValueSerializer">-->
<!--            <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>-->
<!--        </property>-->

        <!--3.GenericJackson2JsonRedisSerializer序列化，优点:可读性较好,存储方便|缺点:占用内存较大,ssm个人选用-->
        <property name="keySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
        <property name="valueSerializer">
            <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
        </property>
        <property name="hashKeySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
        <property name="hashValueSerializer">
        <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
        </property>

        <!--4.Jackson2RedisSerializer序列化,配置文件的方式不知道,会配置的可以说下,谢谢,可以通过@bean配置,boot个人选用 -->
    </bean>
