搭建Spring MVC+JedisCluster集群

系统：Ubuntu

开发工具：eclipse

JDK：1.8

服务器：Tomcat8.0

Redis：3.0.7

搭建流程：

1.搭建spring框架，见文章：http://blog.youkuaiyun.com/u012810317/article/details/51452604

2.在pom.xml中添加Redis依赖:

<!-- redis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.1</version>
</dependency>

3.在springMVC-servlet.xml中添加以下内容：

<context:component-scan base-package="com.springmvc.repository" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" />
</context:component-scan>

4.在src/main/resources下创建connect-redis.properties文件；文件内容如下：

address1=192.168.56.102:7000
address2=192.168.56.102:7001
address3=192.168.56.103:7000
address4=192.168.56.103:7001
address5=192.168.56.104:7000
address6=192.168.56.105:7001

5.在src/main/java中创建com.springmvc.repository包，并在包中创建JedisClusterFactory.java；内容如下：

package com.springmvc.repository;

import java.io.InputStream;
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.stereotype.Repository;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
 
@Repository
public class JedisClusterFactory implements FactoryBean<JedisCluster>, InitializingBean {
  
    private InputStream is;
    private String addressKeyPrefix ;
    private JedisCluster jedisCluster;
    private Integer timeout;
    private Integer maxRedirections;
    private GenericObjectPoolConfig genericObjectPoolConfig;
      
    private Pattern p = Pattern.compile("^.+[:]\\d{1,5}\\s*$");
  
    @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;
    }
  
    private Set<HostAndPort> parseHostAndPort() throws Exception {
        try {
            Properties prop = new Properties();
            prop.load(is);


            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 void afterPropertiesSet() throws Exception {
    is = getClass().getResourceAsStream("/connect-redis.properties");
    addressKeyPrefix = "address";
    timeout = 300000;
    maxRedirections = 6;
    genericObjectPoolConfig = new GenericObjectPoolConfig();
    genericObjectPoolConfig.setMaxWaitMillis(-1);
    genericObjectPoolConfig.setMaxTotal(1000);
    genericObjectPoolConfig.setMinIdle(8);
    genericObjectPoolConfig.setMaxIdle(100);
   
        Set<HostAndPort> haps = this.parseHostAndPort();
        jedisCluster = new JedisCluster(haps, timeout, maxRedirections,genericObjectPoolConfig);
    }
}

6.将src/main/java/com/springmvc/test的HelloController.java文件修改成：

package com.springmvc.test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import redis.clients.jedis.JedisCluster;

@Controller
public class HelloController {
@Autowired
private JedisCluster jediscluster;

@RequestMapping("/hello")
public String hello(@RequestParam(value="name",required=false,defaultValue="world")String name,Model model){
System.out.println(jediscluster.get("CM::百度::5608646537"));
model.addAttribute("name",name);
return "hello";
}
}

7.将src/main/webapp下的index.jsp文件修改成：

<html>
<body>
<a href="/springmvc/hello">hello</a>
</body>
</html>

8.右键项目--> Run As --> Run on Server --> Finish -->在浏览器地址栏输入“localhost:8080/springmvc” --> 点击页面中的“hello”;

如果控制台出现Value的值，则表示成功，否则失败。
