解决spring集成redisson踩过的坑

作者:丶诸子百家

这篇文章主要介绍了spring集成redisson踩过的坑,具有很好的参考价值,希望对大家有所帮助。如有错误或未考虑完全的地方,望不吝赐教

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_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.<init>(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:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:redisson="http://redisson.org/schema/redisson"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
  http://www.springframework.org/schema/context

  http://redisson.org/schema/redisson
       http://redisson.org/schema/redisson/redisson.xsd">
<beans profile="development">
       <!--redisson -->
  <!--<redisson:client id="redissonClient">
   <redisson:single-server address="redis://182.92.97.141:5802"/>
  </redisson:client>-->
    </beans>

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

<xsd:element name="single-server"> // 单节点
<xsd:element name="sentinel-servers"> // 哨兵
<xsd:element name="cluster-servers"> // 集群
<xsd:element name="master-slave-servers"> // 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<String> 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();

    //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<String> 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();
