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：

@Configuration

public class RedissionConfig {

Logger log = LoggerFactory.getLogger(RedissionConfig.class);

@Value("${redis_iphttp://}")

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-ty.handler.codec.ByteToMessageDecoder.decodeRemovalReentryProtection(ByteToMessageDecoder.java:502) at io-ty.handler.codec.ReplayingDecoder.callDecode(ReplayingDecoder.java:366) at io-ty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:278) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io-ty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io-ty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io-ty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io-ty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io-ty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io-ty.channel.ChannelInboundHandlerAdapter.channelRead(ChannelInboundHandlerAdapter.java:86) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io-ty.channel.AbstractChannelHandlerContext.fireChannelRead(AbstractChannelHandlerContext.java:340) at io-ty.channel.DefaultChannelPipeline$HeadContext.channelRead(DefaultChannelPipeline.java:1434) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:362) at io-ty.channel.AbstractChannelHandlerContext.invokeChannelRead(AbstractChannelHandlerContext.java:348) at io-ty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:965) at io-ty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:163) at io-ty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:656) at io-ty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:591) at io-ty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:508) at io-ty.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value

keyObject.set("value");

//最后关闭RedissonClient

redisson.shutdown();

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http://，就设置key的值为value

keyObject.set("value");

//最后关闭RedissonClient

redisson.shutdown();

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)
