1. spring-boot整合Redis

1 pom.xml中新增Jedis依賴， 新增Fastjson依賴

        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.38</version>
        </dependency>
 

2 application.properties中新增配置

#redis
redis.host=10.110.3.62
redis.port=6379
redis.timeout=10
redis.password=123
redis.poolMaxTotal=1000
redis.poolMaxIdle=500

3 建立redis

• 1 controller

@RequestMapping("/redis/get")
@ResponseBodypublic Result<User> redisGet(){
    User  user  = redisService.get(UserKey.getById, ""+1, User.class);    return Result.success(user);}
@RequestMapping("/redis/set")
@ResponseBodypublic Result<Boolean> redisSet(){
    User user = new User();    user.setId(1);    user.setName("test_redis");    Boolean b = redisService.set(UserKey.getById, "1", user);    String str = redisService.get(UserKey.getByName, "name", String.class);    return Result.success(true);}
 

• 2 service

// 首先注入jedisPool
@AutowiredJedisPool jedisPool;

    + RedisPoolFactory生產JedisPool物件

@Servicepublic class RedisPoolFactory {
    @Autowired    RedisConfig redisConfig;    @Bean    public JedisPool JedisPoolFactory(){
        JedisPoolConfig poolConfig = new JedisPoolConfig();        poolConfig.setMaxIdle(redisConfig.getPoolMaxIdle());        poolConfig.setMaxTotal(redisConfig.getPoolMaxTotal());        poolConfig.setMaxWaitMillis(redisConfig.getPoolMaxWait());        JedisPool jp = new JedisPool(poolConfig, redisConfig.getHost(), redisConfig.getPort(),                redisConfig.getTimeout() * 1000, redisConfig.getPassword(), 0);        return jp;    }

}
 

    + RedisPoolFactory 依賴的RedisConfig

@Component@ConfigurationProperties(prefix = "redis")
public class RedisConfig {
    private String host;    private int port;    private int timeout;//秒    private String password;    private int poolMaxTotal;    private int poolMaxIdle;    private int poolMaxWait;//秒
  // 還有對應的get/set方法

• 編寫service層呼叫redis程式碼

// 關鍵程式碼：jedis.setex(realKey, seconds, str);


/** *  設定物件 * @param prefix * @param key * @param value * @param <T> * @return */public <T> boolean set(KeyPrefix prefix, String key, T value){
    Jedis jedis = null;    try{
        jedis = jedisPool.getResource();        String str = beanToString(value);        if(str == null || str.length() <= 0){
            return false;        }
        // 生成真正的key        String realKey = prefix.getPrefix() + key;        int seconds = prefix.expireSeconds();        if(seconds <= 0){
            jedis.set(realKey, str);        }else{
            jedis.setex(realKey, seconds, str);        }
        return true;    }finally {
        returnToPool(jedis);    }
}
public <T> T get(KeyPrefix prefix, String key, Class<T> clazz){
    Jedis jedis = null;    try{
        jedis = jedisPool.getResource();        // 生成真正的key        String realKey = prefix.getPrefix() + key;        String str = jedis.get(realKey);        T t = stringToBean(str, clazz);        return t;    }finally {
        returnToPool(jedis);     }
}
