springboot连接Redis的教程详解
创建springboot项目
在NoSQL中选择Redis
项目目录
pom.xml中还需要加入下面的jar包
org.springframework.bootspring-boot-starter-json
在application.properties文件中添加Redis服务器信息
spring.redis.host=192.168.5.132 spring.redis.port=6379
剩下4个test类，我直接以源码的方式粘出来，里面有些代码是非必须的，我保留了测试的验证过程，所以里面会有冗余代码。（这些代码在我GitHub上的练习项目中也有）
packagecom.myspringboot.redis;
importorg.springframework.boot.SpringApplication;
importorg.springframework.boot.autoconfigure.SpringBootApplication;
importorg.springframework.context.ConfigurableApplicationContext;
@SpringBootApplication
publicclassDemoApplication{
publicstaticvoidmain(String[]args){
ConfigurableApplicationContextconfigurableApplicationContext=SpringApplication.run(DemoApplication.class,args);
RedisTestredisTest=configurableApplicationContext.getBean(RedisTest.class);
redisTest.testRedis();
}
}
