springmvc关于redisCluster的使用及配置

2023-03-07 15:14:12

首先附上maven仓库jar包的下载地址:https://repo.spring.io/webapp/#/artifacts/browse/tree/General/libs-release-local/org

首先在linux系统安装redis3.0以上的版本,并且保证redis集群已经启动:

本次项目所需jar包:

完整图视:

1 新建属性文件:在src/conf/redis.properties:

address0=127.0.0.1:7000
address1=127.0.0.1:7001
address2=127.0.0.1:7002
address3=127.0.0.1:7003
address4=127.0.0.1:7004
address5=127.0.0.1:7005

redis.timeout=300000
redis.maxActive=1024
redis.minIdle=8
redis.maxIdle=100
redis.maxWaitMillis=1000
redis.maxRedirections=6
redis.testOnBorrow=true

2 新建文件夹 :src/xml/redis-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

   <context:property-placeholder location="classpath:/conf/redis.properties" ignore-unresolvable="true"/>
    <context:component-scan base-package="conf"/>
    <bean name="genericObjectPoolConfig" class="org.apache.commons.pool2.impl.GenericObjectPoolConfig">
        <property name="maxWaitMillis" value="-1" />
        <property name="maxTotal" value="1000" />
        <property name="minIdle" value="8" />
        <property name="maxIdle" value="100" />
        <property name="testOnBorrow" value="true" />
    </bean>
    <bean id="jedisCluster" class="testDao.JedisClusterFactory">
        <property name="addressConfig" value="classpath:/conf/redis.properties"/>
        <property name="addressKeyPrefix" value="address" />   
        <property name="timeout" value="300000" />
        <property name="maxRedirections" value="6" />
        <property name="genericObjectPoolConfig" ref="genericObjectPoolConfig" />
    </bean>
</beans>

3 实现bean工厂:src/testDao/JedisClusterFactory

package testDao;

import java.util.HashSet;
import java.util.Properties;
import java.util.Set;
import java.util.regex.Pattern;
import org.apache.commons.pool2.impl.GenericObjectPoolConfig;

import org.springframework.beans.factory.FactoryBean;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.core.io.Resource;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
public class JedisClusterFactory implements FactoryBean<JedisCluster>, InitializingBean{

   private Resource addressConfig;
   private String addressKeyPrefix ;
   private JedisCluster jedisCluster;
   private Integer timeout;
   private Integer maxRedirections;
   private GenericObjectPoolConfig genericObjectPoolConfig;
   private Pattern p = Pattern.compile("^.+[:]\\d{1,5}\\s*$");


   public JedisClusterFactory() {

   }
   @Override
   public void afterPropertiesSet() throws Exception {
           Set<HostAndPort> haps = this.parseHostAndPort();

            jedisCluster = new JedisCluster(haps, timeout, maxRedirections,genericObjectPoolConfig);

   }

private Set<HostAndPort> parseHostAndPort() throws Exception{
       try {
            Properties prop = new Properties();
            prop.load(this.addressConfig.getInputStream());

            Set<HostAndPort> haps = new HashSet<HostAndPort>();
            for (Object key : prop.keySet()) {

                if (!((String) key).startsWith(addressKeyPrefix)) {
                    continue;
                }

                String val = (String) prop.get(key);

                boolean isIpPort = p.matcher(val).matches();

                if (!isIpPort) {
                    throw new IllegalArgumentException("ip 或 port 不合法");
                }
                String[] ipAndPort = val.split(":");

                HostAndPort hap = new HostAndPort(ipAndPort[0], Integer.parseInt(ipAndPort[1]));
                haps.add(hap);
            }

            return haps;
        } catch (IllegalArgumentException ex) {
            throw ex;
        } catch (Exception ex) {
            throw new Exception("解析 jedis 配置文件失败", ex);
        }
   }

@Override
   public JedisCluster getObject() throws Exception {

       return jedisCluster;
   }

@Override
   public Class<? extends JedisCluster> getObjectType() {
       return (this.jedisCluster != null ? this.jedisCluster.getClass() : JedisCluster.class);
   }

@Override
   public boolean isSingleton() {
          return true;
   }

public void setAddressConfig(Resource addressConfig) {
        this.addressConfig = addressConfig;
    }

    public void setTimeout(int timeout) {
        this.timeout = timeout;
    }

    public void setMaxRedirections(int maxRedirections) {
        this.maxRedirections = maxRedirections;
    }

    public void setAddressKeyPrefix(String addressKeyPrefix) {
        this.addressKeyPrefix = addressKeyPrefix;
    }

    public void setGenericObjectPoolConfig(GenericObjectPoolConfig genericObjectPoolConfig) {
        this.genericObjectPoolConfig = genericObjectPoolConfig;
    }
}

4 新建Test类测试redis-cluster

public class Test {

@Autowired
   static
   JedisCluster jedisCluster;
   private static ApplicationContext context;
   static{
        context = new ClassPathXmlApplicationContext("classpath:/xml/redis-context.xml");
   }
   public static void main(String[] args) {
       jedisCluster = (JedisCluster) context.getBean("jedisCluster",JedisCluster.class);

       System.out.println(jedisCluster.get("name1"));
       System.out.println(jedisCluster.get("name2"));
         System.out.println(jedisCluster.get("first"));
         int num = 100;
         String key = "wusc";
         String value = "";
         for (int i=1; i <= num; i++){
           // 存数据
//             jedisCluster.set(key+i,"WuShuicheng"+i);
             // 取数据
             value= jedisCluster.get(key+i);
             System.out.println(value);
//             // 删除数据
//             jedisCluster.del(key+i);
        }
   }

}
