1、配置文件yaml :java
task:
core:
poolsize: 100
max:
poolsize: 200
queue:
capacity: 200
keepAlive:
seconds: 30
thread:
name:
prefix: msgcenterspring
2、java 代码配置异步
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.ThreadPoolExecutor;br/>@Configuration
@EnableAsync
public class AsyncConfig {ide
//接收报文核心线程数 @Value("${task.core.poolsize}") private int taskCorePoolSize; //接收报文最大线程数 @Value("${task.max.poolsize}") private int taskMaxPoolSize; //接收报文队列容量 @Value("${task.queue.capacity}") private int taskQueueCapacity; //接收报文线程活跃时间(秒) @Value("${task.keepAlive.seconds}") private int taskKeepAliveSeconds; //接收报文默认线程名称 @Value("${task.thread.name.prefix}") private String taskThreadNamePrefix; /** * bookTaskExecutor:(接口的线程池). <br/> * * @return TaskExecutor taskExecutor接口 * @since JDK 1.8 */ @Bean() public ThreadPoolTaskExecutor bookTaskExecutor() { //newFixedThreadPool ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); // 设置核心线程数 executor.setCorePoolSize(taskCorePoolSize); // 设置最大线程数 executor.setMaxPoolSize(taskMaxPoolSize); // 设置队列容量 executor.setQueueCapacity(taskQueueCapacity); // 设置线程活跃时间(秒) executor.setKeepAliveSeconds(taskKeepAliveSeconds); // 设置默认线程名称 executor.setThreadNamePrefix(taskThreadNamePrefix); // 设置拒绝策略 // rejection-policy:当pool已经达到max size的时候,如何处理新任务 // CALLER_RUNS:不在新线程中执行任务,而是由调用者所在的线程来执行 executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy()); // 等待全部任务结束后再关闭线程池 executor.setWaitForTasksToCompleteOnShutdown(true); executor.initialize(); return executor;
}
}线程
3、异步方法,添加@Async() 注解code
@Async() @Override public void addAppExceldata(List<AppointUploadUserVo> list, String taskId, int type) throws Exception { } } 以上方法从一万上传效率提高到5万 ,而且在一分钟只能请求接口不超时。
