如何创建一个简单的SpringDataRedisDemo

（1）构建Maven工程 

（2）引入依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.lixiuyang</groupId>
  <artifactId>springdataredis-demo</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>

  <!--版本控制-->
  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  </properties>

  <dependencies>
    <!-- 缓存 -->
    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.9.0</version>
    </dependency>

    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-pool2</artifactId>
      <version>2.0</version>
    </dependency>

    <!--spring-data-redis-->
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>1.8.8.RELEASE</version>
    </dependency>

    <!--test-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>4.3.12.RELEASE</version>
      <scope>test</scope>
    </dependency>

    <!-- Test dependencies -->
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

  <build>
    <defaultGoal>install</defaultGoal>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.6.1</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
        <version>3.0.2</version>
        <configuration>
          <encoding>UTF-8</encoding>
        </configuration>
      </plugin>
    </plugins>

    <!--IDEA编译src的java文件，而目录下的xml文件并不会一起打包，需要手动指定哪些配置文件需要读取-->
    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.xml</include>
          <include>**/*.properties</include>
        </includes>
      </resource>
      <resource>
        <directory>src/main</directory>
        <includes>
          <include>**/*.conf</include>
        </includes>
      </resource>
    </resources>
  </build>
</project>

（4）创建spring/spring-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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:cache="http://www.springframework.org/schema/cache"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/cache
        http://www.springframework.org/schema/cache/spring-cache.xsd">

    <!--加载解析配置文件-->
    <context:property-placeholder location="classpath:redis-config.properties" />

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

    <!--Jedis连接工厂对象-->
    <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"/>

    <!--Jedis对缓存操作的模板对象-->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="JedisConnectionFactory" />
    </bean>
</beans>

（4）在src/main/resources下创建properties文件夹，建立redis-config.properties(没有密码则不写)

redis.host=localhost
redis.port=6379 
redis.pass=
redis.database=0 
redis.maxIdle=300 //最大空闲数
redis.maxWait=3000 //连接时最大等待毫秒数
redis.testOnBorrow=true //在提取一个jedis实例时，是否提前进行验证操作；如果为true，则得到的jedis实例均是可用的

（5）编写一个测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/spring-redis.xml")
public class DataRedisTest {
    @Autowired
    private RedisTemplate redisTemplate;

    /***
     * 增加数据测试
     */
    @Test
    public void testSetValue(){
        redisTemplate.boundValueOps("name").set("hello");
    }

    /***
     * 查询数据
     */
    @Test
    public void testGetValue(){
        String name = (String) redisTemplate.boundValueOps("name").get();
        System.out.println(name);
    }

    /**
     * 删除数据
     */
    @Test
    public void testDeleteValue(){
        redisTemplate.delete("name");
    }
}

试没问题，说明你已成功搭建了一个项目环境！缓存技术的存在为了处理高并发提供了另一个解决方案，那就是Redis集群！有兴趣的朋友可以留言，一起讨论
