使用CassandraAutoConfiguration配置Cassandra策略

Question

使用CassandraAutoConfiguration时yml配置应如何配置Class<? extends ...>字段，例如reconnectionPolicy: com.datastax.driver.core.policies.ConstantReconnectionPolicy with delayMs = 3000

Answer 1

所以似乎提供ClusterBuilderCustomizer自定义属性是唯一的选择。

  @Bean
public ClusterBuilderCustomizer clusterBuilderCustomizer(CassandraBaseProperties properties) {
    return builder -> builder.withReconnectionPolicy(
            new ConstantReconnectionPolicy(properties.getReconnectionPolicyConstantDelayMs()));
}
