解決spring集成redisson踩過(guò)的坑
spring集成redisson踩過(guò)的坑
我用spring的xml集成一直報(bào)錯(cuò)，所以只能選擇注解方式：
@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問(wèn)題
我用的Spring是4.2.7，第一次集成的是3.12.0，會(huì)報(bào)以下錯(cuò)誤：
嚴(yán)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，就不會(huì)報(bào)錯(cuò)了。
第二個(gè)坑是設(shè)置密碼問(wèn)題
因?yàn)橐獏^(qū)分多環(huán)境，所以把redis的信息寫到配置文件中，如果按照上面的配置，會(huì)報(bào)以下錯(cuò)誤：
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
所以要判斷密碼是否為空，如果是空不做參數(shù)即可，下面是改正過(guò)的代碼：
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，網(wǎng)上的帖子好多直接放的ip+端口號(hào)，但是我本地會(huì)報(bào)錯(cuò)，一定在加redis://192.168.2.128:6379這種格式的，可能是因?yàn)榘姹締?wèn)題，也有可能就是誤導(dǎo)人的。
看到上面的報(bào)錯(cuò)，感覺(jué)知道xml的錯(cuò)誤了：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"

</beans>
沒(méi)有設(shè)置密碼，一定不要把password屬性放上去，要不會(huì)報(bào)錯(cuò)的~
spring整合redisson配置
配置方式
redis的部署方式有單節(jié)點(diǎn)部署、哨兵方式部署、集群方式部署3種方式
各種配置方式可以去看xsd文件：redisson-1.1.xsd
<xsd:element name="single-server"> // 單節(jié)點(diǎn) <xsd:element name="sentinel-servers"> // 哨兵 <xsd:element name="cluster-servers"> // 集群 <xsd:element name="master-slave-servers"> // 主從
等其他方式
單節(jié)點(diǎn)配置standalone
單純的java代碼，基于單節(jié)點(diǎn)部署為了保證數(shù)據(jù)的備份，一般會(huì)添加一個(gè)節(jié)點(diǎn)作為slave來(lái)備份master節(jié)點(diǎn)上的數(shù)據(jù)
//創(chuàng)建配置
Config config = new Config();
//指定使用單節(jié)點(diǎn)部署方式
config.useSingleServer().setAddress("redis://127.0.0.1:6379");
//創(chuàng)建客戶端(發(fā)現(xiàn)這一非常耗時(shí)，基本在2秒-4秒左右)
RedissonClient redisson = Redisson.create(config);
//首先獲取redis中的key-value對(duì)象，key不存在沒(méi)關(guān)系
RBucket<String> keyObject = redisson.getBucket("key");
//如果key存在，就設(shè)置key的值為新值value
//如果key不存在，就設(shè)置key的值為value
keyObject.set("value");
//最后關(guān)閉RedissonClient
redisson.shutdown();

//指定使用哨兵部署方式
config.useSentinelServers()
//設(shè)置sentinel.conf配置里的sentinel別名
//比如sentinel.conf里配置為sentinel monitor my-sentinel-name 127.0.0.1 6379 2,那么這里就配置my-sentinel-name
.setMasterName("my-sentinel-name")

//記住這里不是配置redis節(jié)點(diǎn)的服務(wù)端口和IP，sentinel會(huì)自己把請(qǐng)求轉(zhuǎn)發(fā)給后面monitor的redis節(jié)點(diǎn)
