SpringBoot集成redisson分布式锁

官方文档:https://github.com/redisson/redisson/wiki/%E7%9B%AE%E5%BD%95

1、引用redisson的pom

<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson</artifactId>
    <version>3.5.0</version>
</dependency>

2、定义Lock的接口定义类

import java.util.concurrent.TimeUnit;

public interface DistributedLocker {

    void lock(String lockKey);

    void unlock(String lockKey);

    void lock(String lockKey, int timeout);

    void lock(String lockKey, TimeUnit unit ,int timeout);
}

3、Lock接口实现类

import org.redisson.api.RLock;
import org.redisson.api.RedissonClient;

import java.util.concurrent.TimeUnit;

public class RedissonDistributedLocker implements DistributedLocker {

    private RedissonClient redissonClient;

    @Override
    public void lock(String lockKey) {
        RLock lock = redissonClient.getLock(lockKey);
        lock.lock();
    }

    @Override
    public void unlock(String lockKey) {
        RLock lock = redissonClient.getLock(lockKey);
        lock.unlock();
    }

    @Override
    public void lock(String lockKey, int leaseTime) {
        RLock lock = redissonClient.getLock(lockKey);
        lock.lock(leaseTime, TimeUnit.SECONDS);
    }

    @Override
    public void lock(String lockKey, TimeUnit unit ,int timeout) {
        RLock lock = redissonClient.getLock(lockKey);
        lock.lock(timeout, unit);
    }

    public void setRedissonClient(RedissonClient redissonClient) {
        this.redissonClient = redissonClient;
    }
}

4、redisson属性装配类

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "redisson")
public class RedissonProperties {

    private int timeout = 3000;

    private String address;

    private String password;

    private int connectionPoolSize = 64;

    private int connectionMinimumIdleSize=10;

    private int slaveConnectionPoolSize = 250;

    private int masterConnectionPoolSize = 250;

    private String[] sentinelAddresses;

    private String masterName;

    public int getTimeout() {
        return timeout;
    }

    public void setTimeout(int timeout) {
        this.timeout = timeout;
    }

    public int getSlaveConnectionPoolSize() {
        return slaveConnectionPoolSize;
    }

    public void setSlaveConnectionPoolSize(int slaveConnectionPoolSize) {
        this.slaveConnectionPoolSize = slaveConnectionPoolSize;
    }

    public int getMasterConnectionPoolSize() {
        return masterConnectionPoolSize;
    }

    public void setMasterConnectionPoolSize(int masterConnectionPoolSize) {
        this.masterConnectionPoolSize = masterConnectionPoolSize;
    }

    public String[] getSentinelAddresses() {
        return sentinelAddresses;
    }

    public void setSentinelAddresses(String sentinelAddresses) {
        this.sentinelAddresses = sentinelAddresses.split(",");
    }

    public String getMasterName() {
        return masterName;
    }

    public void setMasterName(String masterName) {
        this.masterName = masterName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getConnectionPoolSize() {
        return connectionPoolSize;
    }

    public void setConnectionPoolSize(int connectionPoolSize) {
        this.connectionPoolSize = connectionPoolSize;
    }

    public int getConnectionMinimumIdleSize() {
        return connectionMinimumIdleSize;
    }

    public void setConnectionMinimumIdleSize(int connectionMinimumIdleSize) {
        this.connectionMinimumIdleSize = connectionMinimumIdleSize;
    }
}

5、SpringBoot自动装配类

import org.apache.commons.lang3.StringUtils;
import org.redisson.Redisson;
import org.redisson.api.RedissonClient;
import org.redisson.config.Config;
import org.redisson.config.SentinelServersConfig;
import org.redisson.config.SingleServerConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.longge.lock.DistributedLocker;
import com.longge.lock.RedissonDistributedLocker;
import com.longge.lock.RedissonProperties;
import com.longge.utils.RedissLockUtil;

@Configuration
@ConditionalOnClass(Config.class)
@EnableConfigurationProperties(RedissonProperties.class)
public class RedissonAutoConfiguration {

    @Autowired
    private RedissonProperties redssionProperties;

    /**
     * 哨兵模式自动装配
     * @return
     */
    @Bean
    @ConditionalOnProperty(name="redisson.master-name")
    RedissonClient redissonSentinel() {
        Config config = new Config();
        SentinelServersConfig serverConfig = config.useSentinelServers().addSentinelAddress(redssionProperties.getSentinelAddresses())
                .setMasterName(redssionProperties.getMasterName())
                .setTimeout(redssionProperties.getTimeout())
                .setMasterConnectionPoolSize(redssionProperties.getMasterConnectionPoolSize())
                .setSlaveConnectionPoolSize(redssionProperties.getSlaveConnectionPoolSize());

        if(StringUtils.isNotBlank(redssionProperties.getPassword())) {
            serverConfig.setPassword(redssionProperties.getPassword());
        }
        return Redisson.create(config);
    }

    /**
     * 单机模式自动装配
     * @return
     */
    @Bean
    @ConditionalOnProperty(name="redisson.address")
    RedissonClient redissonSingle() {
        Config config = new Config();
        SingleServerConfig serverConfig = config.useSingleServer()
                .setAddress(redssionProperties.getAddress())
                .setTimeout(redssionProperties.getTimeout())
                .setConnectionPoolSize(redssionProperties.getConnectionPoolSize())
                .setConnectionMinimumIdleSize(redssionProperties.getConnectionMinimumIdleSize());

        if(StringUtils.isNotBlank(redssionProperties.getPassword())) {
            serverConfig.setPassword(redssionProperties.getPassword());
        }

        return Redisson.create(config);
    }

    /**
     * 装配locker类,并将实例注入到RedissLockUtil中
     * @return
     */
    @Bean
    DistributedLocker distributedLocker(RedissonClient redissonClient) {
        DistributedLocker locker = new RedissonDistributedLocker();
        locker.setRedissonClient(redissonClient);
        RedissLockUtil.setLocker(locker);
        return locker;
    }

}

6、Lock帮助类

import java.util.concurrent.TimeUnit;

import com.longge.lock.DistributedLocker;

/**
 * redis分布式锁帮助类
 * @author yangzhilong
 *
 */
public class RedissLockUtil {
    private static DistributedLocker redissLock;

    public static void setLocker(DistributedLocker locker) {
        redissLock = locker;
    }

    public static void lock(String lockKey) {
        redissLock.lock(lockKey);
    }

    public static void unlock(String lockKey) {
        redissLock.unlock(lockKey);
    }

    /**
     * 带超时的锁
     * @param lockKey
     * @param timeout 超时时间   单位:秒
     */
    public static void lock(String lockKey, int timeout) {
        redissLock.lock(lockKey, timeout);
    }

    /**
     * 带超时的锁
     * @param lockKey
     * @param unit 时间单位
     * @param timeout 超时时间
     */
    public static void lock(String lockKey, TimeUnit unit ,int timeout) {
        redissLock.lock(lockKey, unit, timeout);
    }
}

属性文件实例:

1、单机模式

# redisson lock
redisson.address=redis://10.18.75.115:6379
redisson.password=

这里如果不加redis://前缀会报URI构建错误,

Caused by: java.net.URISyntaxException: Illegal character in scheme name at index 0

其次,在redis进行连接的时候如果不对密码进行空判断,会出现AUTH校验失败的情况。

Caused by: org.redisson.client.RedisException: ERR Client sent AUTH, but no password is set. channel

2、哨兵模式

redisson.master-name=mymaster
redisson.password=xxxx
redisson.sentinel-addresses=10.47.91.83:26379,10.47.91.83:26380,10.47.91.83:26381

Redisson 分布式锁超简封装

Redisson是一个在Redis的基础上实现的Java驻内存数据网格.它几乎提供了Redis所有工具,不仅封装Redis底层数据结构,而且还提供了很多Java类型映射.Redisson支持redis单实例.redis哨兵.redis cluster.redis master-slave等各种部署架构.Redisson除了普通分布式锁还支持 联锁(MultiLock),读写锁(ReadWriteLock),公平锁(Fair Lock),红锁(RedLock),信号量(Semaphore),可过期
