cassandra-replication_factor 和 consistency level

参考

replication_factor 决定了数据会被写到多少个节点。为2表示要写到两个节点。

consistency level决定客户端要等待多少个节点被写成功。为1表示只要第一个节点被写成功，客户就发送下一个写请求。

读操作也有自己的consistency level，决定读操作时的行为。

如果只有一个节点服务器，缺设置 replication_factor为2呢？

cassandra只会写一次。

玩转spring boot——properties配置

前言 在以往的java开发中,程序员最怕大量的配置,是因为配置一多就不好统一管理,经常出现找不到配置的情况.而项目中,从开发测试环境到生产环境,往往需要切换不同的配置,如测试数据库连接换成生产数据库连接,若有一处配错或遗漏,就会带来不可挽回的损失.正因为这样,spring boot给出了非常理想的解决方案——application.properties.见application-properties的官方文档:http://docs.spring.io/spring-boot/docs/curr

SpringBoot的核心注解和配置

一.入口类和SpringBootApplication Spring Boot的项目一般都会有*Application的入口类,入口类中会有main方法,这是一个标准的Java应用程序的入口方法. @SpringBootApplication注解是Spring Boot的核心注解,它是一个组合注解: @SpringBootConfiguration:这是Spring Boot项目的配置注解,这也是一个组合注解,与@Configuration作用相同,标识这是一个被装载的Bean,在Spring
