SpringBoot实现自定义Redis的连接

SpringBoot实现自定义Redis的连接

1.docker安装Redis

docker run -p 6379:6379 --name redis -v /mydata/redis/data:/data -v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf -d redis redis-server /etc/redis/redis.conf

2.maven 的pom文件导包

<dependency>
     	<groupId>org.redisson</groupId>
     	<artifactId>redisson-spring-boot-starter</artifactId>
</dependency>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-configuration-processor</artifactId>
 </dependency>

3.自定义属性

在application.yml文件中加入你自己想要的配置

redis:
	config:
		host: 192.168.200.142 #填你redis安装的电脑的ip
	  	port: 6379
	  	password: 你的密码
	  	pool-size: 10
	  	min-idle-size: 5
	  	idle-timeout: 30000
	  	connect-timeout: 5000
	  	retry-attempts: 3
	  	retry-interval: 1000
	  	ping-interval: 60000
	  	keep-alive: true

4.读取配置

@Data
@ConfigurationProperties(prefix = "redis.config", ignoreInvalidFields = true)
public class RedisClientConfigProperties {

    private String host;
    
    private int port;

    private String password;

    private int poolSize = 64;

    private int minIdleSize = 10;

    private int idleTimeout = 10000;

    private int connectTimeout = 10000;

    private int retryAttempts = 3;

    private int retryInterval = 1000;

    private int pingInterval = 0;

    private boolean keepAlive = true;

}

ignoreInvalidFields字段含义

当这个属性设置为true时，Spring会忽略配置文件中那些与配置类字段不匹配的属性。这意味着，如果配置文件中存在与配置类字段不存在的属性，Spring不会抛出异常，而是忽略这些属性。

注入容器

@Configuration
@EnableConfigurationProperties(RedisClientConfigProperties.class)
public class RedisClientConfig {

    @Bean("redissonClient")
    public RedissonClient redissonClient(ConfigurableApplicationContext applicationContext, RedisClientConfigProperties properties) {
        Config config = new Config();
        
        //设置编码器
        config.setCodec(new JsonJacksonCodec());

        config.useSingleServer()
                .setAddress("redis://" + properties.getHost() + ":" + properties.getPort())
                .setPassword(properties.getPassword())
                .setConnectionPoolSize(properties.getPoolSize())
                .setConnectionMinimumIdleSize(properties.getMinIdleSize())
                .setIdleConnectionTimeout(properties.getIdleTimeout())
                .setConnectTimeout(properties.getConnectTimeout())
                .setRetryAttempts(properties.getRetryAttempts())
                .setRetryInterval(properties.getRetryInterval())
                .setPingConnectionInterval(properties.getPingInterval())
                .setKeepAlive(properties.isKeepAlive())
        ;

        return Redisson.create(config);
    }

各个参数含义

• setAddress：连接的地址和端口
• setPassword：密码
• setConnectionPoolSize：设置连接池的大小
• setConnectionMinimumIdleSize：设置连接池的最小空闲连接数
• setIdleConnectionTimeout：设置连接的最大空闲时间（单位：毫秒），超过该时间的空闲连接将被关闭
• setConnectTimeout：设置连接超时时间（单位：毫秒）
• setRetryAttempts：设置连接重试次数
• setRetryInterval：设置连接重试的间隔时间（单位：毫秒）
• setPingConnectionInterval：设置定期检查连接是否可用的时间间隔（单位：毫秒）
• setKeepAlive：设置是否保持长连接
