This article will explain in detail the example analysis of setting redis passwords for springboot integrated redis support. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

The recently used spring boot project needs to integrate the redis cluster, and you need to set the password when connecting to the redis. However, after setting the password, it is found that the boot integrated redis does not support setting the password (the same is true for the redis single node). Once you set the password, an error will be reported: Jedis does not support password protected Redis Cluster configurations

The version of boot I use is 1.4.x

Org.springframework.boot spring-boot-starter-parent 1.4.7.RELEASE

I took a look at the source code, which is shown in the figure:

Once it is found in the source code that you have set a password, directly throw an exception and get drunk.

Then I looked at the Redis-related version of the default integration, where the jedis version is 2.8.x, and the version of JedisCluster is 1.7.x, and none of the constructors in the corresponding version contain password parameters.

Solution 1: replace the versions of jedis and spring-data-redis

Before modification, the maven depends on the following

Org.springframework.boot spring-boot-starter-data-redis

The modified maven dependencies are as follows

Org.springframework.boot spring-boot-starter-data-redis redis.clients jedis org.springframework.data spring-data-redis redis.clients jedis 2.9.0 org.springframework.data spring-data-redis 1.8.0.RELEASE

Solution 2: upgrade boot version 1.5 or above

Org.springframework.boot spring-boot-starter-parent 1.5.2.RELEASE

In boot 1.5.x, the default jedis version is 2.9.x, and the default is 1.8.x, so you can use the redis password for verification.

Redis configuration example in application.properties file

# spring.redis.host = 140.143.23.94spring.redis.password = 123456#spring.redis.port = 637 connections timeout unit ms (milliseconds) spring.redis.timeout = 6000spring.redis.cluster.nodes = 12.2.3.14 123456#spring.redis.port 7001, 12.2.3.14, 7002, 12.2.3.14, 7003, 12.2.3.14, maximum idle connections in the connection pool The default value is also 8spring.redis.pool.max-idle = minimum idle connections in the connection pool, and the default value is 0spring.redis.pool.min-idle = idle. If the value is-1, there is no limit. If pool has allocated maxActive jedis instances, the status of pool is exhausted. Spring.redis.pool.max-active = 8 # maximum time to wait for available connections, in milliseconds. The default value is-1, which means that you will never time out. If more than waiting time, then directly throw spring.redis.pool.max-wait =-1 on "springboot integrated redis support to set redis password example analysis" this article will share here, I hope the above content can be of some help to you, so that you can learn more knowledge, if you think the article is good, please share it out for more people to see.
