java 自定义线程池

import lombok.Getter;

import javax.annotation.PostConstruct;
import java.util.concurrent.*;
//创建一个线城池
public class LogOptionThreadPool {
    private static final ThreadFactory mThreadFactory = new ThreadFactory() {
        //线程的名字
        public Thread newThread(Runnable r) {
            return new Thread(r,"OperationLogThread");
        }
    };
    BlockingQueue<Runnable> workQueue=new LinkedBlockingDeque<>(1000);

    @Getter
    ThreadPoolExecutor logThread;

    @PostConstruct
    public void init(){
        logThread=new ThreadPoolExecutor(2,2,60, TimeUnit.SECONDS,workQueue,
                mThreadFactory,  new ThreadPoolExecutor.CallerRunsPolicy());
        logThread.prestartAllCoreThreads();
    }
}

//在service中注入该线程，调用execute方法，开启线程，线程里面放入参数

@Service
@RequiredArgsConstructor
public class LogOptionalService {
    // 异步保存操作记录
    private final LogOptionThreadPool logOptionThreadPool;

    public void doLog(T t){
　　　　　//参数目前都是随便写的
        logOptionThreadPool.getLogThread().execute(new OptionRun(t));
    }
}

在实现类中，继承 Runnable 接口，然后在run方法里面实现具体的逻辑

public class OptionRun implements Runnable{
    private Integer teamId;
    private String operationName;
    private String operation;

    public OptionRun(Integer teamId, String operationName, String operation) {
        this.teamId = teamId;
        this.operationName = operationName;
        this.operation = operation;
    }

    public void run() {
        //处理逻辑
        //insert(teamId,operationName,operation);
    }
}
