Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis] with root cause

springboot运行不了，报错原因

redis无法连接

错误原因显示"Caused by: java.net.ConnectException: Connection refused: no further information"

此种情况一般都是Redis服务器没有启动或者配置文件参数配置错误造成的。

注意配置文件格式

spring.data.redis.host=192.168.187.140
spring.data.redis.port=6379
spring.data.redis.database=0
spring.data.redis.jedis.pool.max-wait=-1ms
