springboot @Async 多线程使用

 

测试版本

 

1.5 和 2.0.4 完全一样

 

 

一、配置类 AsyncConfig

import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import com.ly.async.AsyncExceptionHandler;
import java.util.concurrent.Executor;

@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {
    
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(100);
        executor.setQueueCapacity(100);
        executor.setWaitForTasksToCompleteOnShutdown(true);
        executor.setAwaitTerminationSeconds(60 * 10);
        executor.setThreadNamePrefix("AsyncThread-");
        executor.initialize(); //如果不初始化，导致找到不到执行器
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new AsyncExceptionHandler();
    }
}
