spring集成redisson踩过的坑 我用spring的xml集成一直报错,所以只能选择注解方式:
@Configurationpublic class RedissionConfig { Logger log = LoggerFactory.getLogger(RedissionConfig.class); @Value("${redis_ip}")String redis_ip; @Value("${redis_port}")String redis_port; @Value("${redis_password}")String redis_password; @Bean(name="redissonClient")public RedissonClient init(){log.info("redis_ip:"+redis_ip); log.info("redis_port:" +redis_port); log.info("redis_password:"+redis_password); Config config = new Config(); String url = "redis://"+redis_ip+":"+redis_port; log.info(url); config.useSingleServer().setAddress(url).setPassword(redis_password); RedissonClient redissonClient = Redisson.create(config); log.info("初始化RedissonClient"); return redissonClient; } }


第一坑就是版本兼容问题
我用的Spring是4.2.7,第一次集成的是3.12.0,会报以下错误:
严重: Unable to process Jar entry [module-info.class] from Jar [jar:file:/C:/Users/Administrator/.m2/repository/com/fasterxml/jackson/dataformat/jackson-dataformat-yaml/2.10.1/jackson-dataformat-yaml-2.10.1.jar!/] for annotations org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 19 at org.apache.tomcat.util.bcel.classfile.Constant.readConstant(Constant.java:133) at org.apache.tomcat.util.bcel.classfile.ConstantPool.(ConstantPool.java:60) at org.apache.tomcat.util.bcel.classfile.ClassParser.readConstantPool(ClassParser.java:209) at org.apache.tomcat.util.bcel.classfile.ClassParser.parse(ClassParser.java:119) at org.apache.catalina.startup.ContextConfig.processAnnotationsStream(ContextConfig.java:2134) at org.apache.catalina.startup.ContextConfig.processAnnotationsJar(ContextConfig.java:2010) at org.apache.catalina.startup.ContextConfig.processAnnotationsUrl(ContextConfig.java:1976) at org.apache.catalina.startup.ContextConfig.processAnnotations(ContextConfig.java:1961) at org.apache.catalina.startup.ContextConfig.webConfig(ContextConfig.java:1319) at org.apache.catalina.startup.ContextConfig.configureStart(ContextConfig.java:878) at org.apache.catalina.startup.ContextConfig.lifecycleEvent(ContextConfig.java:376) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.util.LifecycleBase.fireLifecycleEvent(LifecycleBase.java:90) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5322) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask.run$$$capture(FutureTask.java:266) at java.util.concurrent.FutureTask.run(FutureTask.java) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748)
所以把版本降低到3.10.0,就不会报错了。

第二个坑是设置密码问题
因为要区分多环境,所以把redis的信息写到配置文件中,如果按照上面的配置,会报以下错误:
Caused by: org.redisson.client.RedisException: ERR Client sent AUTH, but no password is set. channel: [id: 0xe37c85e0, L:/192.168.0.128:54867 - R:192.168.0.128/192.168.0.128:5802] command: (AUTH), params: [] at org.redisson.client.handler.CommandDecoder.decode(CommandDecoder.java:314) at org.redisson.client.handler.CommandDecoder.decodeCommand(CommandDecoder.java:130) at org.redisson.client.handler.CommandDecoder.decode(CommandDecoder.java:110) at io.netty.handler.codec.ByteToMessageDecoder.decodeRemovalReentryProtection(ByteToMessageDecoder.java:502) at io.netty.handler.codec.ReplayingDecoder.callDecode(ReplayingDecoder.java:366) at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:278) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io.netty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io.netty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io.netty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io.netty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io.netty.channel.DefaultChannelPipeline$HeadContext.channelRead(DefaultChannelPipeline.java:1434) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io.netty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io.netty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:965) at io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:163) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:656) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:591) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:508) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:470) ... 3 more
所以要判断密码是否为空,如果是空不做参数即可,下面是改正过的代码:
public RedissonClient init(){log.info("redis_ip:"+redis_ip); log.info("redis_port:" +redis_port); log.info("redis_password:"+redis_password); Config config = new Config(); String url = "redis://"+redis_ip+":"+redis_port; log.info(url); SingleServerConfig singleServerConfig = config.useSingleServer().setAddress(url); if(!StringUtils.isEmpty(redis_password)){singleServerConfig.setPassword(redis_password); }RedissonClient redissonClient = Redisson.create(config); log.info("初始化RedissonClient"); return redissonClient; }

另外,网上的帖子好多直接放的ip+端口号,但是我本地会报错,一定在加redis://192.168.2.128:6379这种格式的,可能是因为版本问题,也有可能就是误导人的。
看到上面的报错,感觉知道xml的错误了:

没有设置密码,一定不要把password属性放上去,要不会报错的~

spring整合redisson配置
配置方式
redis的部署方式有单节点部署、哨兵方式部署、集群方式部署3种方式
各种配置方式可以去看xsd文件:redisson-1.1.xsd
// 单节点 // 哨兵 // 集群 // 主从

等其他方式

单节点配置standalone
单纯的java代码,基于单节点部署为了保证数据的备份,一般会添加一个节点作为slave来备份master节点上的数据
//创建配置Config config = new Config(); //指定使用单节点部署方式config.useSingleServer().setAddress("redis://127.0.0.1:6379"); //创建客户端(发现这一非常耗时,基本在2秒-4秒左右)RedissonClient redisson = Redisson.create(config); //首先获取redis中的key-value对象,key不存在没关系RBucket keyObject = redisson.getBucket("key"); //如果key存在,就设置key的值为新值value//如果key不存在,就设置key的值为valuekeyObject.set("value"); //最后关闭RedissonClientredisson.shutdown();

spring整合pom
org.redissonredisson2.10.4 redis.clientsjedis1.7.1.RELEASEorg.springframework.dataspring-data-redis1.7.1.RELEASE

spring整合redisson.xml


哨兵配置sentinel
纯java代码
//创建配置Config config = new Config(); //指定使用哨兵部署方式config.useSentinelServers()//设置sentinel.conf配置里的sentinel别名//比如sentinel.conf里配置为sentinel monitor my-sentinel-name 127.0.0.1 6379 2,那么这里就配置my-sentinel-name.setMasterName("my-sentinel-name")//这里设置sentinel节点的服务IP和端口,sentinel是采用Paxos拜占庭协议,一般sentinel至少3个节点//记住这里不是配置redis节点的服务端口和IP,sentinel会自己把请求转发给后面monitor的redis节点.addSentinelAddress("redis://127.0.0.1:26379").addSentinelAddress("redis://127.0.0.1:26389").addSentinelAddress("redis://127.0.0.1:26399"); //创建客户端(发现这一非常耗时,基本在2秒-4秒左右)RedissonClient redisson = Redisson.create(config); //首先获取redis中的key-value对象,key不存在没关系RBucket keyObject = redisson.getBucket("key"); //如果key存在,就设置key的值为新值value//如果key不存在,就设置key的值为valuekeyObject.set("value"); //最后关闭RedissonClientredisson.shutdown();

spring整合redis和redisson的配置文件

使用
@Autowired@Lazyprivate RedissonClient redissonClient; /*** @param key 具体键值* @return 锁对象*/public RReadWriteLock getLock(String key) {return redissonClient.getReadWriteLock(key); }


集群配置cluster
纯java代码
//创建配置Config config = new Config(); //指定使用集群部署方式config.useClusterServers()// 集群状态扫描间隔时间,单位是毫秒.setScanInterval(2000)//cluster方式至少6个节点(3主3从,3主做sharding,3从用来保证主宕机后可以高可用).addNodeAddress("redis://127.0.0.1:6379" ).addNodeAddress("redis://127.0.0.1:6380").addNodeAddress("redis://127.0.0.1:6381").addNodeAddress("redis://127.0.0.1:6382").addNodeAddress("redis://127.0.0.1:6383").addNodeAddress("redis://127.0.0.1:6384"); //创建客户端(发现这一非常耗时,基本在2秒-4秒左右)RedissonClient redisson = Redisson.create(config); //首先获取redis中的key-value对象,key不存在没关系RBucket keyObject = redisson.getBucket("key"); //如果key存在,就设置key的值为新值value//如果key不存在,就设置key的值为valuekeyObject.set("value"); //最后关闭RedissonClientredisson.shutdown();

使用方式与哨兵配置方式相同,@Autowired注入即可

主从部署方式(master/slave)
纯java代码
//创建配置Config config = new Config(); //指定使用主从部署方式config.useMasterSlaveServers()//设置redis主节点.setMasterAddress("redis://127.0.0.1:6379")//设置redis从节点.addSlaveAddress("redis://127.0.0.1:6380", "redis://127.0.0.1:6381"); //创建客户端(发现这一非常耗时,基本在2秒-4秒左右)RedissonClient redisson = Redisson.create(config); //首先获取redis中的key-value对象,key不存在没关系RBucket keyObject = redisson.getBucket("key"); //如果key存在,就设置key的值为新值value//如果key不存在,就设置key的值为valuekeyObject.set("value"); //最后关闭RedissonClientredisson.shutdown();

以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
