Spring5简单整合Redis(单机)


以下使用的是配置文件整合(单机Redis)

整合的版本,spring5.2.7 + Redis客户端Jedis3.1.0 + Redis6.0.6

1、创建新的maven空项目.

目录结构

目录结构

2、导入依赖.

<properties>
    <spring.version>5.2.7.RELEASE</spring.version>
</properties>

<dependencies>
    <!-- springmvc -->
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <!-- lombok 需要导入插件 -->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.16</version>
    </dependency>

    <!-- test -->
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>${spring.version}</version>
    </dependency>

    <!-- jackson -->
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.11.2</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.11.2</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.11.2</version>
    </dependency>

    <!-- redis -->
    <!-- spring-data-redis -->
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-redis</artifactId>
        <version>2.3.4.RELEASE</version>
    </dependency>
    <!-- redis客户端 -->
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>3.1.0</version>
    </dependency>
</dependencies>

3、创建redis.properties.

文件内容如下

redis.host=ip地址
redis.port=6379 # 默认端口
redis.password=你的Redis设置的密码 如果没有就不必设置
redis.timeout=2000
redis.pool.maxTotal=100
redis.pool.maxIdle=20
redis.pool.maxWaitMills=2000
redis.pool.testOnBorrow=true

4、编写 applicationContext.xml.

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

    <context:property-placeholder location="redis.properties"/>

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <!-- 最小维持连接数 -->
        <property name="maxIdle" value="${redis.pool.maxIdle}"/>
        <!-- 最大可用连接数 -->
        <property name="maxTotal" value="${redis.pool.maxTotal}"/>
        <!-- 最大等待连接数 -->
        <property name="maxWaitMillis" value="${redis.pool.maxWaitMills}"/>
        <!-- 可用连接 -->
        <property name="testOnBorrow" value="${redis.pool.testOnBorrow}"/>
    </bean>

    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="poolConfig" ref="jedisPoolConfig"/>
        <property name="hostName" value="${redis.host}"/>
        <property name="password" value="${redis.password}"/>
        <property name="timeout" value="${redis.timeout}"/>
    </bean>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="valueSerializer">
<!--            <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>-->
            <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
        </property>
        <property name="stringSerializer">
            <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
            <!--            <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer"/>-->
        </property>
        <property name="keySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>
        <property name="hashKeySerializer">
            <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
        </property>

    </bean>
</beans>

5、编写实体类 User.

需要序列化

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {
    private static final long serialVersionUID = -6954400516630825467L;

    private String name;
    private String pwd;
}

6、编写测试类.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class TestRedis {

    @Autowired
    RedisTemplate<String, Object> redisTemplate;

    @Test
    public void test(){
        ValueOperations<String, Object> str = redisTemplate.opsForValue();
        str.set("spring5","redis6");
        System.out.println(str.get("spring5"));
    }
}

测试结果
