代码生成（springboot集成Actor实现数据并发处理入库）

以下是一个基于 Spring Boot 和 Akka 的代码示例，演示了如何利用 Actor 模型实现数据并发处理入库。

### 1. 引入依赖

在 `pom.xml` 文件中添加以下依赖：

<dependency>
    <groupId>com.typesafe.akka</groupId>
    <artifactId>akka-actor_2.12</artifactId>
    <version>2.6.10</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

### 2. 定义 Actor

定义一个 Actor，用于并行处理接收到的数据并将其保存到数据库中。

import akka.actor.AbstractActor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceUnit;

@Component
public class DataWriterActor extends AbstractActor {

    @PersistenceUnit
    private EntityManagerFactory entityManagerFactory;

    @Autowired
    public DataWriterActor(EntityManagerFactory entityManagerFactory) {
        this.entityManagerFactory = entityManagerFactory;
    }

    @Override
    public Receive createReceive() {
        return receiveBuilder()
                .match(DataMessage.class, data -> {
                    saveData(data);
                })
                .build();
    }

    private void saveData(DataMessage data) {
        EntityManager entityManager = entityManagerFactory.createEntityManager();
        try {
            entityManager.getTransaction().begin();
            entityManager.persist(data.getData());
            entityManager.getTransaction().commit();
        } catch (Exception e) {
            entityManager.getTransaction().rollback();
            e.printStackTrace();
        } finally {
            entityManager.close();
        }
    }
}

### 3. 定义消息

定义一个消息类，用于传递需要处理的数据。

public class DataMessage {
    private Object data;

    public DataMessage(Object data) {
        this.data = data;
    }

    public Object getData() {
        return data;
    }
}

### 4. 配置 ActorSystem

在 Spring Boot 的配置类中创建一个 ActorSystem，并将 DataWriterActor 注册到该 ActorSystem 中。

import akka.actor.ActorRef;
import akka.actor.ActorSystem;
import akka.actor.Props;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ActorSystemConfig {

    @Autowired
    private EntityManagerFactory entityManagerFactory;

    @Bean
    public ActorSystem actorSystem() {
        ActorSystem actorSystem = ActorSystem.create("DataWriterActorSystem");
        ActorRef dataWriterActor = actorSystem.actorOf(Props.create(DataWriterActor.class, entityManagerFactory));
        return actorSystem;
    }
}

### 5. 发送消息

在需要处理数据的地方，通过 ActorSystem 发送消息给 DataWriterActor 进行处理。

import akka.actor.ActorRef;
import akka.actor.ActorSystem;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class DataProcessor {

    @Autowired
    private ActorSystem actorSystem;

    public void processData(Object data) {
        ActorRef dataWriterActor = actorSystem.actorSelection("/user/dataWriterActor").resolveOne().value().get();
        dataWriterActor.tell(new DataMessage(data), ActorRef.noSender());
    }
}

以上就是利用 Spring Boot 和 Akka 实现数据并发处理入库的示例代码。
