1 在SpringBoot中常规的配置
<dependency>
<!--自带lettcute客户端-->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>
RedisProperties类会映射yaml文件中的redis相关配置
redis:
host: 10.20.5.47
port: 6379
password:
database: 0
lettuce:
pool:
# Whether to enable the pool. Enabled automatically if "commons-pool2" is available. With Jedis, pooling is implicitly enabled in sentinel mode and this setting only applies to single node setup. 项目里需要引入commons-pool2依赖
enabled: true
min-idle: 16
max-idle: 16
max-active: 64
max-wait: 3000
// 基于 spring boot starter data redis 3.0
@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)

/**
