SpringBoot+Redis整合

SpringBoot+Redis整合

1.在pom.xml添加Redis依赖

        <!--整合Redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>
        <!--整合Redis-->

2.在application.yml配置Redis

#引入Redis 安装在Linux
jedis :
  pool :
    host : 192.168.13.128
    port : 6379
    password: 123456
    timeout: 10000
    config :
      maxTotal: 100
      maxIdle: 10
      maxWaitMillis : 100000

　　

3.在Resources添加redis.properties

#redis配置开始
# Redis数据库索引（默认为0）
spring.redis.database=0
# Redis服务器地址
spring.redis.host=192.168.13.128
# Redis服务器连接端口
spring.redis.port=6379
# Redis服务器连接密码（默认为空）
spring.redis.password=123456
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.jedis.pool.max-active=1024
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.jedis.pool.max-wait=10000
# 连接池中的最大空闲连接
spring.redis.jedis.pool.max-idle=200
# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=0
# 连接超时时间（毫秒）
spring.redis.timeout=10000
#redis配置结束
spring.redis.block-when-exhausted=true

　　

4.配置RedisConfiguration.java类，自动注入

@Configuration
@PropertySource("classpath:redis.properties")
public class RedisConfiguration {

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

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

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

    @Value("${spring.redis.jedis.pool.max-idle}")
    private int maxIdle;

    @Value("${spring.redis.jedis.pool.max-wait}")
    private long maxWaitMillis;

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

    @Value("${spring.redis.block-when-exhausted}")
    private boolean  blockWhenExhausted;

    @Bean
    public JedisPool redisPoolFactory()  throws Exception{
        System.out.println("JedisPool注入成功！！");
        System.out.println("redis地址：" + host + ":" + port);
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(maxIdle);
        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
        // 连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true
        jedisPoolConfig.setBlockWhenExhausted(blockWhenExhausted);
        // 是否启用pool的jmx管理功能, 默认true
        jedisPoolConfig.setJmxEnabled(true);
        JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout, password);
        return jedisPool;
    }

}

5.配置Util类：序列化类SerializeUtil，参数静态类RedisConstants，Redis基础操作类RedisUtil

public class SerializeUtil {

    public static byte[] serialize(Object object) {
        ObjectOutputStream oos = null;
        ByteArrayOutputStream baos = null;
        try {
//序列化
            baos = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(baos);
            oos.writeObject(object);
            byte[] bytes = baos.toByteArray();
            return bytes;
        } catch (Exception e) {
        }
        return null;
    }

    public static Object unserialize(byte[] bytes) {
        ByteArrayInputStream bais = null;
        try {
//反序列化
            bais = new ByteArrayInputStream(bytes);
            ObjectInputStream ois = new ObjectInputStream(bais);
            return ois.readObject();
        } catch (Exception e) {
        }
        return null;
    }

    /**
     * 序列化 list 集合
     *
     * @param list
     * @return
     */
    public static byte[] serializeList(List<?> list) throws Exception {
        if (list == null || list.size() == 0) {
            return null;
        }
        ObjectOutputStream oos = null;
        ByteArrayOutputStream baos = null;
        byte[] bytes = null;
        try {
            baos = new ByteArrayOutputStream();
            oos = new ObjectOutputStream(baos);
            for (Object obj : list) {
                oos.writeObject(obj);
            }
            bytes = baos.toByteArray();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            close(oos);
            close(baos);
        }
        return bytes;
    }

    /**
     * 反序列化 list 集合
     *
     * @param
     * @return
     */
    public static List<?> unserializeList(byte[] bytes) throws Exception {
        if (bytes == null) {
            return null;
        }
        List<Object> list = new ArrayList<Object>();
        ByteArrayInputStream bais = null;
        ObjectInputStream ois = null;
        try {
            // 反序列化
            bais = new ByteArrayInputStream(bytes);
            ois = new ObjectInputStream(bais);
            while (bais.available() > 0) {
                Object obj = (Object) ois.readObject();
                if (obj == null) {
                    break;
                }
                list.add(obj);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            close(bais);
            close(ois);
        }
        return list;
    }

}

public class RedisConstants {

    public static final String spilt=":";

    /**
     * redis库0  保存档案树
     */
    public static final Integer datebase0=0;

    /**
     * redis库1  保存档案树
     */
    public static final Integer datebase1=1;

    /**
     * 1.redis库2 保存档案表格
     * 2.保存分页码
     */
    public static final Integer datebase2=2;

    /**
     * redis库3 保存档案image url
     */
    public static final Integer datebase3=3;

    /**
     * 1.redis库4 保存手机验证码
     *
     */
    public static final Integer datebase4=4;

    /**
     * redis库5 保存身份认证信息
     */
    public static final Integer datebase5=5;

    /**
     * redis库6 记录身份认证次数
     */
    public static final Integer datebase6=6;

    /**
     * redis库7 记录重发次数
     */
    public static final Integer datebase7=7;

    /**
     * redis库8 记录任务参数
     */
    public static final Integer datebase8=8;

    public RedisConstants() {

    }

}

@Component
//@Slf4j
public class RedisUtil {

    private static  final Log log= LogFactory.getLog(RedisUtil.class);

    @Autowired
    private JedisPool jedisPool;

    public RedisUtil() {
    }

    /**
     * <p>
     * 通过key获取储存在redis中的value
     * </p>
     * <p>
     * 并释放连接
     * </p>
     *
     * @param key
     * @param indexdb 选择redis库 0-15
     * @return 成功返回value 失败返回null
     */
    public String get(String key,int indexdb) {
        Jedis jedis = null;
        String value = null;
        try {
            jedis = jedisPool.getResource();
            jedis.select(indexdb);
            value = jedis.get(key);
            System.out.println(value);
          //  log.info(value);
        } catch (Exception e) {

         log.error(e.getMessage());
        } finally {
            returnResource(jedisPool, jedis);
        }
        return value;
    }

    /**

     *
     * @param key

     */
    public byte[] get(byte[] key,int indexdb) {
        Jedis jedis = null;
        byte[] value = null;
        try {
            jedis = jedisPool.getResource();
            jedis.select(indexdb);
            value = jedis.get(key);
        } catch (Exception e) {

            log.error(e.getMessage());
        } finally {
            returnResource(jedisPool, jedis);
        }
        return value;
    }
}

6.在Controller添加操作类RedisController

@Controller
@RequestMapping(value="/redis")
public class RedisController{

    @Autowired
    RedisUtil redisUtil;

    @Autowired
    AccountService accountService;

    @RequestMapping(value = "getRedis",method = RequestMethod.POST)
    @ResponseBody
    public ModelMap getRedis() throws Exception {

        //存储String
//        redisUtil.set("20182019","这是一条测试数据1", RedisConstants.datebase1);
//        Long resExpire = redisUtil.expire("20182018", 60, RedisConstants.datebase1);//设置key过期时间
//        String res = redisUtil.get("20182019", RedisConstants.datebase1);
//        String name = redisUtil.get("name", RedisConstants.datebase0);

//        //存储hash-map
//        Map<String, String> map=new HashMap<String,String>();
//        map.put("a","a1");
//        map.put("b","a2");
//        map.put("c","a2");
//        redisUtil.hmset("dd",map,RedisConstants.datebase1);

//        List<String> list111 = (List<String>) redisUtil.getList("testlist");
//        System.out.println(list111);

        //存储list serialize
//       List<UserVO>  userList=accountService.selsetUserList();
//       System.out.println(userList);
//       for(UserVO user:userList){
//           redisUtil.lpush(RedisConstants.datebase1,"userList",user.getUserid()+"");
//           redisUtil.hset("user:"+user.getUserid(),"userId",user.getUserid()+"");
//           redisUtil.hset("user:"+user.getUsername(),"userName",user.getUsername()+"");
//           redisUtil.hset("user:"+user.getEmail(),"usereEail",user.getEmail()+"");
//
//       }

        //获取List数据
      String userId=  redisUtil.hget("userList:"+1,"userId");
      String userName=  redisUtil.hget("userList:"+1,"userName");
      String userEmail=  redisUtil.hget("userList:"+1,"userEmail");
        System.out.println(userId);
        System.out.println(userName);
        System.out.println(userEmail);

        return null;

    }

}
