Spring boot上集成Jedis

梦里梦外; 2022-06-09 00:47 173阅读 0赞

1、首先在pom中添加Jedis依赖

<dependency>  
        <groupId>redis.clients</groupId>  
        <artifactId>jedis</artifactId>  
        <version>2.8.2</version>  
    </dependency>

2、在aplication.properties配置文件中加入Jedis的参数配置

#jedis配置===============================
    #redis服务器地址
    jedis.pool.host=192.168.184.100
    #redis服务器端口
    jedis.pool.port=6379
    #最大连接数
    jedis.pool.config.maxTotal=100
    #最小空闲连接数
    jedis.pool.config.maxIdle=10
    #获取连接时的最大等待毫秒数
    jedis.pool.config.maxWaitMillis=100000
    #redis的auth密码
    jedis.pool.password=0.0.0.

3、创建Jedis的连接配置文件

package com.cy.example.config;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Qualifier;
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    
    import com.cy.example.utils.RedisClient;
    
    import redis.clients.jedis.JedisPool;
    import redis.clients.jedis.JedisPoolConfig;
    import redis.clients.jedis.Protocol;
    
    
    @Configuration
    public class RedisConfig {
    
        private Logger logger = LoggerFactory.getLogger(RedisClient.class);
    
        @Bean(name= "jedis.pool")  
        @Autowired  
        public JedisPool jedisPool(@Qualifier("jedis.pool.config") JedisPoolConfig config,   
                    @Value("${jedis.pool.host}")String host,   
                    @Value("${jedis.pool.port}")int port,
                    @Value("${jedis.pool.password}")String password) {  
            logger.info("缓存服务器的地址："+host+":"+port);
            return new JedisPool(config, host, port,Protocol.DEFAULT_TIMEOUT,password); 
        }
    
        @Bean(name= "jedis.pool.config")  
        public JedisPoolConfig jedisPoolConfig (@Value("${jedis.pool.config.maxTotal}")int maxTotal,  
                                    @Value("${jedis.pool.config.maxIdle}")int maxIdle,  
                                    @Value("${jedis.pool.config.maxWaitMillis}")int maxWaitMillis) {  
            JedisPoolConfig config = new JedisPoolConfig(); 
            config.setMaxTotal(maxTotal); 
            config.setMaxIdle(maxIdle); 
            config.setMaxWaitMillis(maxWaitMillis); 
            return config; 
        }  
    }

4、编写Jedis操作的两个简单接口

package com.cy.example.utils;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired; 
    import org.springframework.stereotype.Component; 
    
    
    import com.cy.example.config.LoginInterceptor;
    
    import redis.clients.jedis.Jedis; 
    import redis.clients.jedis.JedisPool; 
    
    
    @Component  
    public class RedisClient {  
    
        private Logger logger = LoggerFactory.getLogger(RedisClient.class);
    
        @Autowired  
        private JedisPool jedisPool; 
    
        public void set(String key, String value){  
            Jedis jedis = null; 
            try {  
                jedis = jedisPool.getResource(); 
                jedis.set(key, value); 
            } catch(Exception e){
                logger.info("缓存服务器连接失败！");
            }finally {
                //返还到连接池  
                jedis.close(); 
            }  
        }  
    
        public String get(String key){  
            String value = "";
            Jedis jedis = null; 
            try {  
                jedis = jedisPool.getResource(); 
                value = jedis.get(key);
            } catch(Exception e){
                logger.info("缓存服务器连接异常！");
            }finally {
                //返还到连接池  
                jedis.close(); 
            }  
            return value;
        }  
    
    }

5、写一个简单的测试demo

package com.cy.example.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import redis.clients.jedis.Jedis;
    
    import com.cy.example.utils.RedisClient;
    
    /* * 测试redis */
    @Controller
    @RequestMapping("/redis")
    public class RedisController {
    
        @Autowired  
        private RedisClient redisClinet; 
    
        @RequestMapping("/set")  
        public String set(String key, String value) throws Exception{  
            redisClinet.set(key, value); 
            return "success";
        }
    
        @RequestMapping("/get")  
        public String get(String key) throws Exception {  
            return redisClinet.get(key);
        }  
    }
