添加配置

spring:

redis:

lettuce:

pool:

max-active: 8

max-idle: 8

min-idle: 2 # 保持最小空闲连接数

max-wait: 1000ms

time-between-eviction-runs: 30000 # 空闲连接检测周期（毫秒）

redisconfig配置增加

复制代码

@Bean
public LettuceConnectionFactory redisConnectionFactory() {
   RedisStandaloneConfiguration serverConfig = new RedisStandaloneConfiguration(host, port);
   serverConfig.setPassword(password);

   LettuceClientConfiguration clientConfig = LettuceClientConfiguration.builder()
         .commandTimeout(Duration.ofSeconds(5))  // 增加命令超时时间
         .shutdownTimeout(Duration.ofSeconds(2))  // 增加关闭超时时间
         .clientOptions(ClientOptions.builder()
               .autoReconnect(true)
               .disconnectedBehavior(ClientOptions.DisconnectedBehavior.REJECT_COMMANDS)  // 断开连接时拒绝命令
               .pingBeforeActivateConnection(true)  // 连接前PING测试
               .build())
         .build();

   LettuceConnectionFactory factory = new LettuceConnectionFactory(serverConfig, clientConfig);
   factory.setValidateConnection(true);  // 在工厂级别设置连接验证
