1.檢視6379埠是否開放

[[email protected] src]# firewall-cmd --permanent --zone=public --list-ports

下圖為查詢後的結果

如果沒有開放6379埠則根據下面步驟操作

1.1永久的新增該埠。去掉--permanent則表示臨時。

firewall-cmd --permanent --zone=public --add-port=需要開放的埠號/tcp

1.2載入配置，使得修改有效。

firewall-cmd --reload 

2.設定客戶端的protected-mode 為no (禁用保護模式)

config set protected-mode "no"

3.進行最基礎的測試

這裡只需要匯入一個最基本的Jedis包即可

<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.9.0</version>
</dependency>

import org.junit.Test;
import redis.clients.jedis.Jedis;

/**
 * author:wlm
 * name:
 * function:
 * 2018/10/26 18:38
 */
public class javaToRedisTest {
    @Test
    public void redisConnectionTest(){
        Jedis jedis= new Jedis("172.20.10.2",6379);
        jedis.set("test","測試");
        System.out.println(jedis.get("test"));

    }

}
 

到這裡如果測試沒問題接下來就開始整合Redis到SSM中去

一.所需要的jar包（注意版本）

    <!--redis-->
    <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>2.9.0</version>
    </dependency>
    <!-- config redis data and client jar-->
    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-redis</artifactId>
      <version>2.1.0.RELEASE</version>
    </dependency>
    <!--commons-pool2-->
    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-pool2</artifactId>
      <version>2.6.0</version>
    </dependency>
 

二.redis.properties檔案

redis.host=172.30.20.3
redis.port=6379
redis.maxIdle=300
redis.maxWaitMillis=1000
redis.maxTotal=600
redis.testOnBorrow=true
redis.testOnReturn=true

三.redis-context.xml檔案

<?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:p="http://www.springframework.org/schema/p"
       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">
    <!--掃描redis配置檔案-->
    <context:property-placeholder ignore-unresolvable="true" location="classpath:redis.properties"/>
    <!--設定連線池-->
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxIdle" value="${redis.maxIdle}"/>
        <property name="maxTotal" value="${redis.maxTotal}" />
        <property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
        <property name="testOnBorrow" value="${redis.testOnBorrow}" />
        <property name="testOnReturn" value="${redis.testOnReturn}" />
    </bean>
    <!--設定連結屬性-->
    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
          p:hostName="${redis.host}"
          p:port="${redis.port}"
          p:password=""
          p:pool-config-ref="poolConfig"
          p:timeout="100000"/>
    <!-- Jedis模板配置  -->
    <bean id="redisTemplate" class="org.springframework.data.redis.core.StringRedisTemplate">
        <property name="connectionFactory"   ref="connectionFactory" />
    </bean>

</beans>

四.把redis-context.xml檔案引入到spring核心檔案中

<?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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.1.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">


    <!-- 引入redis配置檔案 -->
    <import resource="classpath:redis-context.xml"/>

   
</beans>

 五.測試

/**
 * author:wlm
 * name:
 * function:
 * 2018/10/22 10:12
 */
@Controller
public class StudentController {


    @Autowired
    private RedisTemplate redisTemplate; //注入


    @RequestMapping("add")
    public String addStudent(){
   
        try{
            redisTemplate.opsForValue().set("test", "測試");
            Log4j2Controller.info("value："+redisTemplate.opsForValue().get("chen"));
        }catch(Exception e){
            Log4j2Controller.error("Redis-error");
        }

        return null;
    }

   

}
