• Spring中使用Redis


    普通使用Redis的方法很简单,前面的文章也有讲解,这篇文章主要就是讲解通过注解的方式实现Spring和Redis的整合。
    这里我们创建了3个类:
    1.Config 全局配置类,相当于xml配置文件
    2.RedisTest 启动类,就一个main方法,同时初始化Spring容器
    3.SpringStart 具体操作类,在这个类里面操作具体的Redis

     pom.xml

    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-redis</artifactId>
        <version>1.8.4.RELEASE</version>
    </dependency>

    config

    package cn.duanjt;
    
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    
    import redis.clients.jedis.JedisPoolConfig;
    
    @Configuration
    public class Config {
        @Bean("poolConfig")
        public JedisPoolConfig JedisPoolConfig(){
            JedisPoolConfig config = new JedisPoolConfig();
            config.setMaxTotal(20);
            config.setMaxIdle(5);
            config.setMaxWaitMillis(100);
            config.setTestOnBorrow(true);
            return config;
            //return new JedisPool(config, "172.23.88.107", 6379);
        }
        
        @Bean("jedisConnectionFactory")
        public JedisConnectionFactory JedisConnectionFactory(JedisPoolConfig poolConfig){
            JedisConnectionFactory factory=new JedisConnectionFactory();
            
            factory.setHostName("172.23.88.107");
            factory.setPort(6379);
            factory.setPoolConfig(poolConfig);
            factory.setUsePool(true);
            return factory;
        }
        
        @Bean("redisTemplate")
        public RedisTemplate<String, Object> RedisTemplate(JedisConnectionFactory factory){
            RedisTemplate<String, Object> template=new RedisTemplate<String, Object>();
            template.setConnectionFactory(factory);
            template.setKeySerializer(new StringRedisSerializer());
            template.setValueSerializer(new JdkSerializationRedisSerializer());
            template.setHashKeySerializer(new StringRedisSerializer());
            template.setHashValueSerializer(new JdkSerializationRedisSerializer());
            template.setEnableTransactionSupport(true);//开启事务
            return template;
        }
        
        @Bean
        public SpringStart SpringStart(){
            return new SpringStart();
        }
    }

     RedisTest

    package cn.duanjt;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.annotation.AnnotationConfigApplicationContext;
    
    public class RedisTest {
        public static void main(String[] args) {
            ApplicationContext context = new AnnotationConfigApplicationContext(Config.class);
            SpringStart test=context.getBean(SpringStart.class);
            test.start();
        }
        
    }

    SpringStart

    package cn.duanjt;
    
    import java.util.HashMap;
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.RedisTemplate;
    
    public class SpringStart {
        @Autowired
        RedisTemplate<String, Object> redisTemplate;
    
        public void start() {
            // 设置值
            redisTemplate.opsForValue().set("age", 100);
            // 获取值
            System.out.println("String年龄"+redisTemplate.opsForValue().get("age"));
    
            Map<String, String> map = new HashMap<>();
            map.put("age", "100");
            map.put("name", "张三");
            redisTemplate.opsForHash().putAll("stu:001", map);
            
            System.out.println("Hash姓名:"+redisTemplate.opsForHash().get("stu:001", "age"));
            //redisTemplate.opsForSet();
            //redisTemplate.opsForZSet();
        }
    }

    1.注意最后的redisTemplate.opsForSet()和redisTemplate.opsForZSet(),Redis里面的不同类型对应了一个不同方法

    2.开始启动的时候报了类没有找到的错误,后来排查是因为jedis和spring-data-redis的版本不兼容,后来将jedis修改为2.9.0之后完美解决。
