1.创建项目
如果出现init失败(需要等待网络可以正常连接)
或者运行主类的时候报错(错误: 找不到或无法加载主类),需要重新导入maven项目再重新编译试试。
2.引入pom jar

3.添加redis配置
代码语言:javascript复制server.port=8088
spring.redis.host=127.0.0.1
#Redis服务器连接端口
spring.redis.port=6379
#Redis服务器连接密码(默认为空)
spring.redis.password=
#连接池最大连接数(使用负值表示没有限制)
spring.redis.pool.max-active=8
#连接池最大阻塞等待时间(使用负值表示没有限制)
spring.redis.pool.max-wait=-1
#连接池中的最大空闲连接
spring.redis.pool.max-idle=8
#连接池中的最小空闲连接
spring.redis.pool.min-idle=0
#连接超时时间(毫秒)
spring.redis.timeout=30000
4.controller模拟订单号每次请求增加1
代码语言:javascript复制package com.redis.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@SpringBootApplication
public class DemoApplication {
@Autowired
private StringRedisTemplate redisTemplate;
@RequestMapping("/")
public String demo(){
Long idx = redisTemplate.opsForValue().increment("orderId");
return "Hello World! orderId = " idx;
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
