SpringBoot如何集成Jedis

• 添加jedis依赖

在项目pom.xml文件中添加依赖

<!-- 添加jedis依赖 -->
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>

• 添加redis配置

在项目resources目录中找到application.properties文件添加reids配置信息

# redis
redis.host=10.x.x.x
redis.port=6379 //redis端口
redis.timeout=3
redis.password=xxxx
redis.poolMaxTotal=10   //最大连接池
redis.poolMaxIdle=10    //最大休闲连接
redis.poolMaxWait=3

• 测试例子

首先我们需要定义一个RedisConfig配置类,通过这个配置类对redis的相关属性进行设置与获取

@Component
@ConfigurationProperties(prefix="redis")
public class RedisConfig {
	private String host;
	private int port;
	private String password;
	private int timeout;
	private int poolMaxTotal;
	private int poolMaxIdle;
	private int poolMaxWait;

	public String getHost() {
		return host;
	}
	public void setHost(String host) {
		this.host = host;
	}
	public int getPort() {
		return port;
	}
	public void setPort(int port) {
		this.port = port;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	/*
            Something code....    //一部分属性没有编写，这个自己整理吧
        */
}

接下来,我们就要测试连接redis是否成功.在SpringBoot->Controller层中写上一个获取某个key的值功能.

通常控制层一般调用服务层方法,也就是我们要在服务层里获取Jedis类的实例对象,最后我们实例对象调用相关的方法jedis.get(key)来获取键的值

控制层代码如下

@Controller
public class DemoController {

	@Autowired
	RedisService redisService;

    @RequestMapping("/db/getredis")
	@ResponseBody
	public Result<String> getRedis()
	{
		String strVal = redisService.getInstance().get("Hello");
		return Result.success(strVal);
	}
}

服务层代码如下

@Service
public class RedisService {
    @Autowired
	JedisPool jedisPool;

	@Autowired
	RedisConfig redisConfig;

	public Jedis getInstance(){
		Jedis jedis = new Jedis(redisConfig.getHost(),
				redisConfig.getPort());
		return jedis;
	}
}
