springboot + redis集群和单机切换（密码）自定义配置文件

绝地灬酷狼 2022-02-03 00:07 928阅读 0赞

项目中因为不是使用springRedis的配置，而是采用自定义的配置redis.pool，而且需要进行单机和集群的切换，中间出现了一些jar包冲突的问题，导致部分功能不能使用，还是记录一下，这个找了好久

1、配置文件如下，可能和现行的配置不同，使用model进行区分，当然代码有判断

redis:
      pool:
        maxTotal: 120 # 最大连接数
        maxIdle: 30 # 最大空闲实例的个数
        minIdle: 3 #最小空闲实例个数
        numTestsPerEvictionRun: 1024 # 每个逐出器运行期间要检查的最大对象数
        timeBetweenEvictionRunsMillis: 30000 # 释放扫描的扫描间隔
        minEvictableIdleTimeMillis: 1800000 # 连接的最小空闲时间
        softMinEvictableIdleTimeMillis: 10000 # 连接控歘按时间多久后释放，当空闲时间>该值且空闲连接>最大空闲连接数时直接释放
        maxWaitMillis: 1500 # 获得链接时的最大等待毫秒数，小于0：阻塞不确定时间，默认-1
        testOnBorrow: true # 在获得链接的时候检查有效性，默认false
        testWhileIdle: true # 在空闲时检查有效性，默认false
        blockWhenExhausted: false # 连接耗尽时是否阻塞，false报异常，true阻塞超时,默认true
        timeOut: 10000 # jedis超时时间
      maxRedirects: 5 # RedisClusterConfiguration配置
      nodeCluters: 192.168.98.105:7000,192.168.98.105:7001,192.168.98.105:7002,192.168.98.105:7003,192.168.98.105:7004,192.168.98.105:7005
      hostName: localhost
      password: 43b6f9b82c71c13063a523c0dcbc6db8fc0ac8a0
      port: 6379
      model: 3 #redis的模式1 表示单机，2 表示sentinel， 3表示cluster

2、pom文件

原来使用的pom是1.4.7，但是这个版本好像有点低

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-redis</artifactId>
    	<version>1.4.7.RELEASE</version>
    </dependency>

这个版本在jedisConnectionFactory设置密码处好像不太兼容

因此**需要处理jar的版本冲突问题（敲黑板啦\`\`\`\`\`这个才是重点），需要排除依赖**

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-data-redis</artifactId>
    	<exclusions>
    		<exclusion>
    			<groupId>redis.clients</groupId>
    			<artifactId>jedis</artifactId>
    		</exclusion>
    	    <exclusion>
    		    <groupId>org.springframework.data</groupId>
    			<artifactId>spring-data-redis</artifactId>
    		</exclusion>
    	</exclusions>
    </dependency>
    <dependency>
    	<groupId>redis.clients</groupId>
    	<artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>
    <dependency>
    	<groupId>org.springframework.data</groupId>
    	<artifactId>spring-data-redis</artifactId>
    	<version>1.8.10.RELEASE</version>
    </dependency>

3、一下为具体的config，因为有个工具类需要注入，所以会有CacheUtil，然后里面进行了redis的序列化，据说默认是jdk的序列化方式
