在Spring中使用Redis使用使用两个依赖包jedis.jar、spring-data-redis.jar
一下是Maven项目pom.xml添加依赖
<!--jedis.jar -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>
<!-- Spring下使用Redis -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.7.2.RELEASE</version>
</dependency>
要注意的是jar包和Spring版本的兼容性问题
笔者这里是使用注解方式进行配置
@Configuration
@ComponentScan("the_mass.redis")
public class SpringConfig {
//Spring连接工厂
@Bean
RedisConnectionFactory redisFactory () {
return new JedisConnectionFactory();
}
//反序列化
@Bean
RedisTemplate redisTemplate () {
return new StringRedisTemplate(redisFactory());
}
}
在JedisConnectionFactory可以设置许多参数的在此使用的是本机默认就好了
第二部服务层
package the_mass.redis;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisOperations;
import org.springframework.stereotype.Service;
import java.nio.charset.StandardCharsets;
@Service
public class RedisService {
@Autowired
RedisConnectionFactory factory;
@Autowired
RedisOperations redisOperations;
public void testRedis() {
RedisConnection connection = factory.getConnection();
byte[] bytes = connection.get("hello".getBytes());
System.out.println(new String(bytes, StandardCharsets.UTF_8));
}
public void testRedisTemplate () {
Object hello = redisOperations.opsForValue().get("hello");
System.out.println(hello);
}
}
第三步
package the_mass.redis;
import redis.clients.jedis.Jedis;
public class JedisDemo {
public void execute () {
Jedis jedis = new Jedis();
//Jedis jedis1 = new Jedis("44.55.66.7", 3333);
Boolean hello = jedis.exists("hello");
System.out.println(hello);
String s = jedis.get("hello");
System.out.println(s);
jedis.set("hello:1", "world:23");
Long hello1 = jedis.exists("hello", "hello:123");
System.out.println(hello1);
}
}
第四部在此笔者在redis里面已经有了一个Hello(key)
package the_mass.redis;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
public class Main {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SpringConfig.class);
RedisService redisService = context.getBean(RedisService.class);
//redisService.testRedis();
redisService.testRedisTemplate();
}
}
简单测试
