SpringMVC整合redis(Spring Data Redis)

1.引入依赖(pom文件)

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>2.1.4.RELEASE</version>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

2.redis配置(redis.properties)

redis.host=host
redis.port=6379
redis.password=""
redis.maxIdle=400
redis.maxTotal=6000
redis.maxWaitMillis=1000
redis.blockWhenExhausted=true
redis.testOnBorrow=true
redis.db=1

3.bean配置

方法一：springConfig.xml

<!-- 加载redis配置 -->
<context:property-placeholder location="classpath:properties/redis.properties" />

<bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <!-- 最大空闲数 -->
    <property name="maxIdle" value="${redis.maxIdle}" />
    <!-- 最大空连接数 -->
    <property name="maxTotal" value="${redis.maxTotal}" />
    <!-- 最大等待时间 -->
    <property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
    <!-- 连接超时时是否阻塞，false时报异常,true阻塞直到超时, 默认true -->
    <property name="blockWhenExhausted" value="${redis.blockWhenExhausted}" />
    <!-- 返回连接时，检测连接是否成功 -->
    <property name="testOnBorrow" value="${redis.testOnBorrow}" />
</bean>

<bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
      p:host-name="${redis.host}"
      p:port="${redis.port}"
      p:password="${redis.password}"
      p:database="${redis.db}"
      p:pool-config-ref="poolConfig"/>

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
    <property name="connectionFactory" ref="connectionFactory" />
    <property name="keySerializer">
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
    </property>
    <property name="valueSerializer">
        <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
    </property>
    <property name="hashKeySerializer">
        <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
    </property>
    <property name="hashValueSerializer">
        <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
    </property>
    <!--开启事务  -->
    <property name="enableTransactionSupport" value="true"></property>
</bean>

<!--自定义redis工具类,在需要缓存的地方注入此类  -->
<bean id="redisService" class="services.RedisService">
    <property name="redisTemplate" ref="redisTemplate" />
</bean>

<!--启用spring的一些annotation -->
<context:annotation-config/>

方法二：RedisConfig.java

package configs;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;
import services.RedisService;

@Configuration
public class RedisConfig {

    @Value("${redis.host}")
    private String hostName;

    @Value("${redis.port}")
    private int port;

    @Value("${redis.password}")
    private String password;

    @Value("${redis.db}")
    private int database;


    /**
     * redis链接池配置
     * @return JedisPoolConfig
     */
    @Bean
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();

        jedisPoolConfig.setMaxTotal(100);

        jedisPoolConfig.setMinIdle(20);

        jedisPoolConfig.setMaxWaitMillis(10000);

        return jedisPoolConfig;
    }

    /**
     * redis工厂方法
     * @return JedisConnectionFactory
     */
    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        System.out.println(hostName);

        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(hostName, port);

        redisStandaloneConfiguration.setDatabase(database);

        redisStandaloneConfiguration.setPassword(password);

        return new JedisConnectionFactory(redisStandaloneConfiguration);
    }

    @Bean
    public RedisTemplate redisTemplate(){
        RedisTemplate redisTemplate = new RedisTemplate();

        redisTemplate.setConnectionFactory(jedisConnectionFactory());

        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        redisTemplate.setDefaultSerializer(stringRedisSerializer);

        redisTemplate.setEnableTransactionSupport(true);

        return redisTemplate;
    }

    @Bean
    public RedisService redisService(){
        RedisService redisService = new RedisService();

        redisService.setRedisTemplate(redisTemplate());

        return redisService;
    }
}

4.使用

@Controller
public class HelloController {

    @Resource
    private RedisService redisService;

    @RequestMapping("hello")
    @ResponseBody
    public Movies hello(HttpServletRequest request){
        redisService.getKey();

        Movies movies = new Movies();
        return movies;
    }
}
