redis示例

1. 引入redis相关包

 <!-- redis 相关包-->
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>1.8.6.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.9.0</version>
    </dependency>

2. 配置applicationContext.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.shsxt" />
    <context:annotation-config/>

    <bean id="sentinelConfiguration" class="org.springframework.data.redis.connection.RedisSentinelConfiguration">
        <constructor-arg name="master" value="mymaster" />
        <constructor-arg name="sentinelHostAndPorts">
            <set>
                <value>172.16.54.135:26380</value>
            </set>
        </constructor-arg>
    </bean>

    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="password" value="123456" />
        <property name="usePool" value="true" />
        <constructor-arg name="sentinelConfig" ref="sentinelConfiguration" />
    </bean>

    <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
        <property name="connectionFactory" ref="connectionFactory" />
    </bean>



</beans>

3. 编写redis配置文件

/**
 * Java 配置的操作步骤：
 *  1、编写 RedisConfig 的配置类
 *  2、编写测试类
 *  3、添加 Spring 的配置文件
 *  4、启动测试查看结果
 */
//@Configuration
public class RedisConfig {

    @Bean
    public StringRedisTemplate redisTemplate(){
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(jedisConnectionFactory());
        return stringRedisTemplate;
    }

    @Bean
    public static RedisConnectionFactory jedisConnectionFactory(){
        RedisSentinelConfiguration sentinelConfiguration = new RedisSentinelConfiguration().master("mymaster")
                .sentinel("172.16.54.135",26380);
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(sentinelConfiguration);
        jedisConnectionFactory.setPassword("123456");
        return jedisConnectionFactory;
    }
}

4. 编写启动文件，支持xml和java配置两种方法

package com.shsxt;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.BoundValueOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;

public class Application {

    /**
     * 方法一、java配置
     * @param args
     */
    /*
    public static void main(String[] args) {

        try {
            ApplicationContext context = new FileSystemXmlApplicationContext("classpath:applicationContext.xml");

            JedisConnectionFactory connectionFactory = context.getBean(JedisConnectionFactory.class);

            StringRedisTemplate redisTemplate = new StringRedisTemplate(connectionFactory);
            BoundValueOperations<String,String> boundValueOperations = redisTemplate.boundValueOps("abcd");

            boundValueOperations.set("11111");
            System.out.println("设置完毕。。。");
            String result = boundValueOperations.get();
            System.out.println("获取值为：" + result);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    */

    /**
     * 方法二、xml 配置
     * @param args
     */
    public static void main(String[] args) {

        try {
            ApplicationContext context = new FileSystemXmlApplicationContext("classpath:applicationContext.xml");

            RedisTemplate redisTemplate = context.getBean(RedisTemplate.class);
            BoundValueOperations<String,String> boundValueOperations = redisTemplate.boundValueOps("abde111");
            boundValueOperations.set("111111");
            System.out.println("设置完毕");
            String result = boundValueOperations.get();
            System.out.println("获取值为："+ result);

        } catch (BeansException e) {
            e.printStackTrace();
        }
    }
}
