线程池配置

ThreadPoolConfig

package com.newland.iot.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.task.TaskExecutor;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

@Configuration
public class ThreadPoolConfig {
    @Value("${spring.executor.core.pool.size:500}")
    private Integer corePoolSize;
    @Value("${spring.executor.max.pool.size:0x7fffffff}")
    private Integer maxPoolSize;
    @Value("${spring.executor.queue.capacity:0x7fffffff}")
    private Integer queueCapacity;

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        taskExecutor.setCorePoolSize(corePoolSize);
        taskExecutor.setMaxPoolSize(maxPoolSize);
        taskExecutor.setQueueCapacity(queueCapacity);
        taskExecutor.setWaitForTasksToCompleteOnShutdown(true);
        return taskExecutor;
    }
}

使用

@Component
public class TestTaskExecutor {

    @Autowired
    private TaskExecutor taskExecutor;

    taskExecutor.execute(() -> System.out.println("taskExecutor...");
}
