Redisson
方式1
引入依赖

<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson</artifactId>
    <version>3.15.1</version>
</dependency>

配置文件application.properties

自定义配置

redisson.url=redis://127.0.0.1:6379
配置类

import org.redisson.Redisson;
import org.redisson.api.RedissonClient;
import org.redisson.config.Config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RedissonConfig {

    @Value("${redisson.url}")
    private String redisUrl;

    @Bean
    public RedissonClient getRedissonClient(){
        Config config = new Config();
        config.useSingleServer().setAddress(redisUrl);
        return Redisson.create(config);
    }
}

使用

import org.redisson.api.RLock;
import org.redisson.api.RedissonClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class DemoService {

    @Autowired
    private RedissonClient redissonClient;

    public void doSomething(){
        RLock lock = redissonClient.getLock("lock_key");

        try {
            lock.lock();
            // TODO 业务逻辑

        } finally {
            lock.unlock();
        }

    }

}

方式2：
依赖

<dependency>
    <groupId>org.redisson</groupId>
    <artifactId>redisson-spring-boot-starter</artifactId>
    <version>3.15.1</version>
</dependency>

配置文件application.properties（这种方式完全兼容SpringBoot配置）

spring.redis.host=127.0.0.1
spring.redis.port=6379
使用

import org.redisson.api.RLock;
import org.redisson.api.RedissonClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class DemoService {

    @Autowired
    private RedissonClient redissonClient;

    public void doSomething(){
        RLock lock = redissonClient.getLock("lock_key");

        try {
            lock.lock();
            // TODO 业务逻辑

        } finally {
            lock.unlock();
        }

    }

}

spring-integration-redis
依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-integration</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-redis</artifactId>
</dependency>

配置文件application.properties

spring.redis.host=127.0.0.1
spring.redis.port=6379
配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.integration.redis.util.RedisLockRegistry;

@Configuration
public class RedisLockConfig {

    @Bean
    public RedisLockRegistry redisLockRegistry(RedisConnectionFactory redisConnectionFactory) {
        return new RedisLockRegistry(redisConnectionFactory, "registry_key");
    }

}

使用

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.integration.redis.util.RedisLockRegistry;
import org.springframework.stereotype.Service;

import java.util.concurrent.locks.Lock;

@Service
public class DemoService {

    @Autowired
    private RedisLockRegistry redisLockRegistry;

    public void doSomething(){
        Lock lock = redisLockRegistry.obtain("lock_key");

        try {
            lock.lock();
            // TODO 业务逻辑
            
        } finally {
            lock.unlock();
        }
    }
}

追加方式：两种方式测试方便合在一块，实际独立的

org.redisson redisson 3.15.1

import org.redisson.Redisson;
import org.redisson.api.RedissonClient;
import org.redisson.config.Config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RedissonConfig {

    @Bean
    public RedissonClient getRedissonClient() {
        Config config = new Config();
        config.useSingleServer().setAddress("redis://127.0.0.1:6379");
        return Redisson.create(config);
    }
}

@Slf4j @RunWith(SpringRunner.class) @SpringBootTest(classes = TaskApplication.class) public class ExceptionTest {

//way of first
//redisson-spring-boot-starter-3.13.6.jar
@Autowired
private RedissonClient redissonClient;

// //way of second // //lock4j-redisson-spring-boot-starter-2.2.2.jar // @Resource // private LockTemplate lockTemplate;

//way of first
@Test
public void redisTest() {
    RLock lock = redissonClient.getLock("this_is_key");
    try {
        lock.lock();
        //模拟业务
        Thread.sleep(5000);
    } catch (Exception e) {
        log.warn("e:{}", e);
    } finally {
        lock.unlock();
    }
}

// //way of second // @Test // public void secondTest(){ // LockInfo lockInfo = null; // try { // lockInfo = lockTemplate.lock("this_is_second_key", 5000L, 0); // // Thread.sleep(5000); // } catch (Exception e) { // log.warn("e:{}", e); // } // // lockTemplate.releaseLock(lockInfo); // } }

\==========第二种

com.baomidou  
lock4j-redisson-spring-boot-starter  
2.2.2

spring: redis: host: 127.0.0.1 port: 6379

@Slf4j
@RunWith(SpringRunner.class)
@SpringBootTest(classes = TaskApplication.class)
public class ExceptionTest {

//    //way of first
//    //redisson-spring-boot-starter-3.13.6.jar
//    @Autowired
//    private RedissonClient redissonClient;

    //way of second
    //lock4j-redisson-spring-boot-starter-2.2.2.jar
    @Resource
    private LockTemplate lockTemplate;


//    //way of first
//    @Test
//    public void redisTest() {
//        RLock lock = redissonClient.getLock("this_is_key");
//        try {
//            lock.lock();
//            //模拟业务
//            Thread.sleep(5000);
//        } catch (Exception e) {
//            log.warn("e:{}", e);
//        } finally {
//            lock.unlock();
//        }
//    }

    //way of second
    @Test
    public void secondTest(){
        LockInfo lockInfo = null;
        try {
            lockInfo = lockTemplate.lock("this_is_second_key", 5000L, 0);

            Thread.sleep(5000);
        } catch (Exception e) {
            log.warn("e:{}", e);
        }

        lockTemplate.releaseLock(lockInfo);
    }
}

```
