springboot 使用多线程和线程池

日常业务中，出于及时响应和效率问题对于涉及日志类的保存操作经常使用多线程处理，这里展示其中的一种调用方式。
因为博主本人不喜欢@Async注解对启动类的侵入，所以使用Runnable接口配合线程池实现多线程的使用。

• 步骤一：创建自定义线程池配置类

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;


@Configuration
public class ThreadPoolConfig {

    
    @Bean
    public ThreadPoolTaskExecutor commonThreadPoolTaskExecutor() {
        ThreadPoolTaskExecutor pool = new org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor();
        // 返回可用处理器的Java虚拟机的数量
        int processNum = Runtime.getRuntime().availableProcessors();
        int corePoolSize = (int) (processNum / (1 - 0.2));
        int maxPoolSize = (int) (processNum / (1 - 0.5));
        // 核心池大小
        pool.setCorePoolSize(corePoolSize);
        // 最大线程数
        pool.setMaxPoolSize(maxPoolSize);
        // 队列程度
        pool.setQueueCapacity(maxPoolSize * 1000);
        pool.setThreadPriority(Thread.MAX_PRIORITY);
        pool.setDaemon(false);
        // 线程空闲时间
        pool.setKeepAliveSeconds(300);
        return pool;
    }
}

• 步骤二：创建Runnable接口的实现类(通过构造方法传入所需参数和对象，在run方法实现相关操作逻辑)

public interface ITaskService extends Runnable {
}

import com.gbx.sms.platform.common.exception.ErrorException;
import com.gbx.sms.platform.module.yidong.domain.SmsLogs;
import com.gbx.sms.platform.module.yidong.dto.YiDongDTO;
import com.gbx.sms.platform.module.yidong.service.ISmsLogsService;
import com.gbx.sms.platform.module.yidong.service.ITaskService;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;


@Slf4j
public class TaskServiceImpl implements ITaskService {

    private ISmsLogsService logsService;
    private YiDongDTO yiDongDTO;

    public TaskServiceImpl(ISmsLogsService logsService, YiDongDTO yiDongDTO) {
        this.logsService = logsService;
        this.yiDongDTO = yiDongDTO;
    }

    @Override
    public void run() {
        SmsLogs smsLogs = SmsLogs.builder()
                .appKey(yiDongDTO.getAppKey())
                .appName(yiDongDTO.getAppName())
                .modeCode(yiDongDTO.getModeCode())
                .modeName(yiDongDTO.getModeName())
                .reqMsg(yiDongDTO.getReqMsg())
                .phone(yiDongDTO.getPhone())
                .build();
        String content = yiDongDTO.getContent();
        if (StringUtils.isNotBlank(content)) {
            if (content.length() > 200) {
                content = content.substring(0, 200);
            }
            smsLogs.setSmsContent(content);
        }
        String code = yiDongDTO.getCode();
        if (StringUtils.isNotBlank(code)) {
            smsLogs.setSmsCode(code);
        }
        int add = logsService.insertSmsLogs(smsLogs);
        if (add <= 0) {
            throw new ErrorException("添加短信调用日志失败，参数：" + yiDongDTO.toString());
        }
    }
}

• 步骤三：对实现多线程的方法进行调用

import cn.hutool.core.lang.Validator;
import cn.hutool.core.util.ObjectUtil;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.gbx.sms.platform.common.constant.HttpStatus;
import com.gbx.sms.platform.common.core.bean.Result;
import com.gbx.sms.platform.common.exception.ErrorException;
import com.gbx.sms.platform.common.utils.SmsSendUtil;
import com.gbx.sms.platform.module.yidong.domain.SmsAuth;
import com.gbx.sms.platform.module.yidong.domain.SmsLogs;
import com.gbx.sms.platform.module.yidong.domain.SmsMode;
import com.gbx.sms.platform.module.yidong.dto.YiDongDTO;
import com.gbx.sms.platform.module.yidong.service.*;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.codec.digest.DigestUtils;
import org.apache.commons.lang3.StringUtils;
import org.apache.tomcat.util.codec.binary.Base64;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.concurrent.TimeUnit;


@Service
@Slf4j
public class SmsYiDongServiceImpl implements SmsYiDongService {
    @Autowired
    private ISmsLogsService logsService;
    @Autowired
    private ThreadPoolTaskExecutor commonThreadPoolTaskExecutor;

    
    @Override
    public Result onlySendSmsMsg(YiDongDTO yiDongDTO) {
                //此处使用线程池的额外线程执行
                try {
                    ITaskService taskService = new TaskServiceImpl(logsService, yiDongDTO);
                    commonThreadPoolTaskExecutor.execute(taskService);
                } catch (Exception eA) {
                    log.error(eA.getMessage());
                }
    }
}

至此，成功实现多线程的使用，可以使用Thread.sleep()查看是否成功。
