SpringBoot如何集成Jedis

Posted 2020-10-27 学无涯鲸拍浪

• 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;
    }
    public int getTimeout() {
        return timeout;
    }
    public void setTimeout(int timeout) {
        this.timeout = timeout;
    }
    public int getPoolMaxTotal() {
        return poolMaxTotal;
    }
    public void setPoolMaxTotal(int poolMaxTotal) {
        this.poolMaxTotal = poolMaxTotal;
    }
    public int getPoolMaxIdle() {
        return poolMaxIdle;
    }
    public void setPoolMaxIdle(int poolMaxIdle) {
        this.poolMaxIdle = poolMaxIdle;
    }
    public int getPoolMaxWait() {
        return poolMaxWait;
    }
    public void setPoolMaxWait(int poolMaxWait) {
        this.poolMaxWait = poolMaxWait;
    }
}

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("k1");
        return Result.success(strVal);
    }
}

服务层代码如下

@Service
public class RedisService {
    @Autowired
    JedisPool jedisPool;
    
    public Jedis getInstance(){
        Jedis jedis = jedisPool.getResource();
        return jedis;
    }
}
