springboot使用多線程調用接口控制層

同樣是拿別人的,整體沒報錯,不過還未經具體測試
配置類: 

package com.tansuo365.test1.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.task.TaskExecutor;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.ThreadPoolExecutor;

@Configuration
@EnableAsync
public class AsyncConfig {

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        // 設置核心線程數
        executor.setCorePoolSize(5);
        // 設置最大線程數
        executor.setMaxPoolSize(10);
        // 設置隊列容量
        executor.setQueueCapacity(20);
        // 設置線程活躍時間（秒）
        executor.setKeepAliveSeconds(60);
        // 設置默認線程名稱
        executor.setThreadNamePrefix("danhao-");
        // 設置拒絕策略
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        // 等待所有任務結束后再關閉線程池
        executor.setWaitForTasksToCompleteOnShutdown(true);
        return executor;
    }
}

注意配置類的新注解 @EnableAsync

控制層:

    @Async
    @RequestMapping("/getChukuNumber")
    public ListenableFuture<String> genBillCode(String type) throws Exception {
        StringBuffer billCodeStr = new StringBuffer();
        billCodeStr.append(chukudanPrefix);
        billCodeStr.append(DateUtil.getCurrentDateStr());
        String todayMaxChukuDanNumber = chukuZongService.getTodayMaxChukuDanNumber();
        if (todayMaxChukuDanNumber != null) {
            billCodeStr.append(StringUtil.formatCode(todayMaxChukuDanNumber));
        } else {
            billCodeStr.append("0001");
        }
        return new AsyncResult<>(billCodeStr.toString());
//        return billCodeStr.toString();
    }

注意控制層的返回類型 返回值 以及新注解@Async
同樣的啟動類上:

//@EnableCaching
@SpringBootApplication
@MapperScan(value = {"com.xxxxxxxxx.test1.mapper"})
@EnableAsync//開啟異步任務
public class Test1Application {

    public static void main(String[] args) {
        SpringApplication.run(Test1Application.class, args);
    }

}

注意啟動類上的 @EnableAsync 注解
