Springboot项目连接Redis（jedis）

1.添加依赖：

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

2.修改配置文件
将application.properties改为yml并添加如下配置：

spring:
  redis:
    database: 0
    host: 192.168.145.128
    password: 123456
    port: 6379
    jedis:  #连接池相关配置
      pool:
        max-active: 8  #最大连接数
        max-idle: 8     #最大空闲数
        min-idle: 1    #最小空闲数

创建jedisConfig类：

package com.example.moduledemo01.config;
@Configuration
@ConfigurationProperties(prefix = "spring.redis")
public class jedisConfig {
    private int database;
    private String host;
    private String password;
    private int port;

    /*
    * 1.jedis连接池配置（得到JDBC连接池）
    *
    * */
    @Bean
public JedisPool jedisPool(){
    /*
    * 连接池
    * */
    JedisPoolConfig jedisPoolConfig=new JedisPoolConfig();
    jedisPoolConfig.setMaxTotal(8);
    jedisPoolConfig.setMaxIdle(8);
    jedisPoolConfig.setMinIdle(1);
    JedisPool jedisPool=new JedisPool(jedisPoolConfig,host,port,2000,password);

    return jedisPool;
}

    public int getDatabase() {
        return database;
    }

    public void setDatabase(int database) {
        this.database = database;
    }

    public String getHost() {
        return host;
    }

    public void setHost(String host) {
        this.host = host;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public int getPort() {
        return port;
    }

    public void setPort(int port) {
        this.port = port;
    }
}

测试：

package com.example.moduledemo01;
@SpringBootTest
class Moduledemo01ApplicationTests {
    @Autowired
    private JedisPool jedisPool;
    @Test
    void contextLoads() {
        //从连接池中得到链接对象
        Jedis jedis = jedisPool.getResource();
        jedis.set("java111","springboot");
        System.out.println(jedis.get("java111"));
        jedis.close();
    }

}
