Redis+nginx +memcached

1、redis是一个nosql的数据库，操作内存数据，并可以将其存储到硬盘中来持久化

2、与spring的整合 http://www.cnblogs.com/holdouts/articles/5811118.html

　　需要jar包common-pool2.jar jedis.jar spring-data-redis.jar

　　spring 配置文件

　　<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 http://www.springframework.org/schema/beans/spring-beans.xsd"
　　 default-autowire="byName">
   　　<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
   　　   <property name="maxIdle" value="${redis.maxIdle}"></property>
      　　 <property name="minEvictableIdleTimeMillis" value="${redis.minEvictableIdleTimeMillis}"></property>
       　　 <property name="numTestsPerEvictionRun" value="${redis.numTestsPerEvictionRun}"></property>
       　　 <property name="timeBetweenEvictionRunsMillis" value="${redis.timeBetweenEvictionRunsMillis}"></property>
   　　 </bean>
   　　<bean id="jedisConnectionFactory"
     　　 class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
       　　 destroy-method="destroy">
       　　 <property name="poolConfig" ref="jedisPoolConfig"></property>
       　　 <property name="hostName" value="${redis.hostName}"></property>
      　　 <property name="port" value="${redis.port}"></property>
       　　 <property name="timeout" value="${redis.timeout}"></property>
       　　 <property name="usePool" value="${redis.usePool}"></property>
   　　 </bean>
   　　 <bean id="jedisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
       　　 <property name="connectionFactory" ref="jedisConnectionFactory"></property>
       　　 <property name="keySerializer">
       　　   <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" /> //代表redis的key/value需要序列化若是实体类，实体类需要实现序列化
       　　 </property>
       　　<property name="valueSerializer">
          　　 <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
       　　 </property>
　　 </bean>
　　</beans>

　　    @Autowired
   　　@Qualifier("jedisTemplate")
   　　public RedisTemplate redisTemplate;

　　需要redis的类中，可以注入redisTemplate

　　有5种数据操作方式

　　redisTemplate.opsForValue();//操作字符串
　　redisTemplate.opsForHash();//操作hash
　　redisTemplate.opsForList();//操作list
　　redisTemplate.opsForSet();//操作set
　　redisTemplate.opsForZSet();//操作

3、nginx的安装与部署

　　http://blog.csdn.net/kingzma/article/details/46331999
　　http://www.runoob.com/linux/nginx-install-setup.html

　cd /home/soft
   　　　　 yum install openssl 　 yum install openssl-devel
  　　　　 yum install zlib-devel    yum install zlib
   　　　　 yum install pcre-devel   yum install pcre
   下载nginx
      wget http://nginx.org/download/nginx-1.13.3.tar.gz
   解压　　 tar -zxvf nginx-1.13.3.tar.gz
      重命名 mv nginx-1.33.3 nginx
　安装 c yum install -y gcc gcc-c++
     编译nginx　　cd /home/soft/nginx
   ./configure
      安装    make make install
      默认安装目录 /usr/local/nginx
      关闭默认防火墙
      systemctl stop firewalld.service #停止firewall
   systemctl disable firewalld.service #禁止firewall开机启动
　　nginx负载均衡 http://blog.csdn.net/kingzma/article/details/46331999

4、memcached的配置

　　http://www.cnblogs.com/mafly/p/memcached.html

<bean id="memcachedClientBuilder" class="net.rubyeye.xmemcached.XMemcachedClientBuilder"
        p:connectionPoolSize="${memcached.connectionPoolSize}" p:failureMode="${memcached.failureMode}">
        
        <constructor-arg>
            <list>
                <bean class="java.net.InetSocketAddress">
                    <constructor-arg>
                        <value>${server1.memcached.host}</value>
                    </constructor-arg>
                    <constructor-arg>
                        <value>${server1.memcached.port}</value>
                    </constructor-arg>
                </bean>
                <bean class="java.net.InetSocketAddress">
                    <constructor-arg>
                        <value>${server2.memcached.host}</value>
                    </constructor-arg>
                    <constructor-arg>
                        <value>${server2.memcached.port}</value>
                    </constructor-arg>
                </bean>
            </list>
        </constructor-arg>
        <constructor-arg>
            <list>
                <value>${server1.memcached.weight}</value>
                <value>${server2.memcached.weight}</value>
            </list>
        </constructor-arg>
        <property name="commandFactory">
            <bean class="net.rubyeye.xmemcached.command.TextCommandFactory" />
        </property>
        <property name="sessionLocator">
            <bean class="net.rubyeye.xmemcached.impl.KetamaMemcachedSessionLocator" />
        </property>
        <property name="transcoder">
            <bean class="net.rubyeye.xmemcached.transcoders.SerializingTranscoder" />
        </property>
   </bean>
   
   <bean id="memcachedClient" factory-bean="memcachedClientBuilder"
        factory-method="build" destroy-method="shutdown" />

　　需要的缓存的类继承该类变可以

　　@Component
　　public class MemcachedBasis {
  　　 @Autowired
   　　protected MemcachedClient memcachedClient;

  　　 protected int Exptime = 3600 * 24;

  　　 protected int DataExptime = this.Exptime * 7;

  　　 protected String Prefix = "SPRINGDEMO:";
　　}
5、redis整合代码

public class UserDAOImpl  implements UserDAO{
    @Autowired
        public RedisTemplate<Serializable, Serializable> redisTemplate;

        public void saveUser(final User user) {
            redisTemplate.execute(new RedisCallback<Object>() {

                @Override
                public Object doInRedis(RedisConnection connection) throws DataAccessException {
                    connection.set(redisTemplate.getStringSerializer().serialize("user.uid." + user.getId()),
                                   redisTemplate.getStringSerializer().serialize(user.getName()));
                    return null;
                }
            });
        }

        @Override
        public User getUser(final long id) {
            return redisTemplate.execute(new RedisCallback<User>() {
                @Override
                public User doInRedis(RedisConnection connection) throws DataAccessException {
                    byte[] key = redisTemplate.getStringSerializer().serialize("user.uid." + id);
                    if (connection.exists(key)) {
                        byte[] value = connection.get(key);
                        String name = redisTemplate.getStringSerializer().deserialize(value);
                        User user = new User();
                        user.setName(name);
                        user.setId(id);
                        return user;
                    }
                    return null;
